# Biergarten Pipeline
|
||||
|
||||
A high-performance C++23 data pipeline for fetching, parsing, and storing geographic data (countries, states, cities) with brewery metadata generation capabilities. The system supports both mock and LLM-based (llama.cpp) generation modes.
|
||||
|
||||
## Overview
|
||||
|
||||
The pipeline orchestrates **four key stages**:
|
||||
|
||||
1. **Download** - Fetches `countries+states+cities.json` from a pinned GitHub commit with optional local filesystem caching
|
||||
2. **Parse** - Streams JSON using Boost.JSON's `basic_parser` to extract country/state/city records without loading the entire file into memory
|
||||
3. **Store** - Inserts records into a file-based SQLite database with all operations performed sequentially in a single thread
|
||||
4. **Generate** - Produces brewery metadata or user profiles (mock implementation; supports future LLM integration via llama.cpp)
|
||||
|
||||
## System Architecture
|
||||
|
||||
### Data Sources and Formats
|
||||
|
||||
- **Hierarchical Structure**: Countries array → states per country → cities per state
|
||||
- **Data Fields**:
|
||||
- `id` (integer)
|
||||
- `name` (string)
|
||||
- `iso2` / `iso3` (ISO country/state codes)
|
||||
- `latitude` / `longitude` (geographic coordinates)
|
||||
- **Source**: [dr5hn/countries-states-cities-database](https://github.com/dr5hn/countries-states-cities-database) on GitHub
|
||||
- **Output**: Structured SQLite file-based database (`biergarten-pipeline.db`) + structured logging via spdlog
|
||||
|
||||
### Concurrency Model
|
||||
|
||||
The pipeline currently operates **single-threaded** with sequential stage execution:
|
||||
|
||||
1. **Download Phase**: Main thread blocks while downloading the source JSON file (if not in cache)
|
||||
2. **Parse & Store Phase**: Main thread performs streaming JSON parse with immediate SQLite inserts
|
||||
|
||||
**Thread Safety**: While single-threaded, the `SqliteDatabase` component is **mutex-protected** using `std::mutex` (`dbMutex`) for all database operations. This design enables safe future parallelization without code modifications.
|
||||
|
||||
## Core Components
|
||||
|
||||
| Component | Purpose | Thread Safety | Dependencies |
|
||||
| ----------------------------- | ----------------------------------------------------------------------------------------------- | -------------------------------------------- | --------------------------------------------- |
|
||||
| **BiergartenDataGenerator** | Orchestrates pipeline execution; manages lifecycle of downloader, parser, and generator | Single-threaded coordinator | ApplicationOptions, WebClient, SqliteDatabase |
|
||||
| **DataDownloader** | HTTP fetch with curl; optional filesystem cache; ETag support and retries | Blocking I/O; safe for startup | IWebClient, filesystem |
|
||||
| **StreamingJsonParser** | Extends `boost::json::basic_parser`; emits country/state/city via callbacks; tracks parse depth | Single-threaded parse; callbacks thread-safe | Boost.JSON |
|
||||
| **JsonLoader** | Wraps parser; dispatches callbacks for country/state/city; manages WorkQueue lifecycle | Produces to WorkQueue; safe callbacks | StreamingJsonParser, SqliteDatabase |
|
||||
| **SqliteDatabase** | Manages schema initialization; insert/query methods for geographic data | Mutex-guarded all operations | SQLite3 |
|
||||
| **IDataGenerator** (Abstract) | Interface for brewery/user metadata generation | Stateless virtual methods | N/A |
|
||||
| **LlamaGenerator** | LLM-based generation via llama.cpp; configurable sampling (temperature, top-p, seed) | Manages llama_model* and llama_context* | llama.cpp, BreweryResult, UserResult |
|
||||
| **MockGenerator** | Deterministic mock generation using seeded randomization | Stateless; thread-safe | N/A |
|
||||
| **CURLWebClient** | HTTP client adapter; URL encoding; file downloads | cURL library bindings | libcurl |
|
||||
| **WikipediaService** | (Planned) Wikipedia data lookups for enrichment | N/A | IWebClient |
|
||||
|
||||
## Database Schema
|
||||
|
||||
SQLite file-based database with **three core tables** and **indexes for fast lookups**:
|
||||
|
||||
### Countries
|
||||
|
||||
```sql
|
||||
CREATE TABLE countries (
|
||||
id INTEGER PRIMARY KEY,
|
||||
name TEXT NOT NULL,
|
||||
iso2 TEXT,
|
||||
iso3 TEXT
|
||||
);
|
||||
CREATE INDEX idx_countries_iso2 ON countries(iso2);
|
||||
```
|
||||
|
||||
### States
|
||||
|
||||
```sql
|
||||
CREATE TABLE states (
|
||||
id INTEGER PRIMARY KEY,
|
||||
country_id INTEGER NOT NULL,
|
||||
name TEXT NOT NULL,
|
||||
iso2 TEXT,
|
||||
FOREIGN KEY (country_id) REFERENCES countries(id)
|
||||
);
|
||||
CREATE INDEX idx_states_country ON states(country_id);
|
||||
```
|
||||
|
||||
### Cities
|
||||
|
||||
```sql
|
||||
CREATE TABLE cities (
|
||||
id INTEGER PRIMARY KEY,
|
||||
state_id INTEGER NOT NULL,
|
||||
country_id INTEGER NOT NULL,
|
||||
name TEXT NOT NULL,
|
||||
latitude REAL,
|
||||
longitude REAL,
|
||||
FOREIGN KEY (state_id) REFERENCES states(id),
|
||||
FOREIGN KEY (country_id) REFERENCES countries(id)
|
||||
);
|
||||
CREATE INDEX idx_cities_state ON cities(state_id);
|
||||
CREATE INDEX idx_cities_country ON cities(country_id);
|
||||
```

|
||||
**Note**: When `--mocked` is used, any sampling parameters (`--temperature`, `--top-p`, `--seed`) are ignored with a warning.
|
||||
|
||||
### Usage Examples
|
||||
|
||||
```bash
|
||||
# Mocked generator (deterministic, no LLM required)
|
||||
./biergarten-pipeline --mocked
|
||||
|
||||
# With LLM model
|
||||
./biergarten-pipeline --model ./models/llama.gguf --cache-dir /var/cache
|
||||
|
||||
# Mocked with extra parameters provided (will be ignored with warning)
|
||||
./biergarten-pipeline --mocked --temperature 0.5 --top-p 0.8 --seed 42
|
||||
|
||||
# Show help
|
||||
./biergarten-pipeline --help
|
||||
```
|
||||
|
||||
## Building and Running
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- **C++23 compiler** (g++, clang, MSVC)
|
||||
- **CMake** 3.20+
|
||||
- **curl** (for HTTP downloads)
|
||||
- **sqlite3** (database backend)
|
||||
- **Boost** 1.75+ (requires Boost.JSON and Boost.Program_options)
|
||||
- **spdlog** v1.11.0 (fetched via CMake FetchContent)
|
||||
- **llama.cpp** (fetched via CMake FetchContent for LLM inference)
|
||||
|
||||
### Build
|
||||
|
||||
```bash
|
||||
mkdir -p build
|
||||
cd build
|
||||
cmake ..
|
||||
cmake --build . --target biergarten-pipeline -- -j
|
||||
```
|
||||
|
||||
### Run
|
||||
|
||||
```bash
|
||||
./build/biergarten-pipeline
|
||||
```
|
||||
|
||||
**Output**:
|
||||
|
||||
- Console logs with structured spdlog output
|
||||
- Cached JSON file: `/tmp/countries+states+cities.json`
|
||||
- SQLite database: `biergarten-pipeline.db` (in output directory)
|
||||
|
||||
## Code Quality and Static Analysis
|
||||
|
||||
### Formatting
|
||||
|
||||
This project uses **clang-format** with the **Google C++ style guide**:
|
||||
|
||||
```bash
|
||||
# Apply formatting to all source files
|
||||
cmake --build build --target format
|
||||
|
||||
# Check formatting without modifications
|
||||
cmake --build build --target format-check
|
||||
```
|
||||
|
||||
### Static Analysis
|
||||
|
||||
This project uses **clang-tidy** with configurations for Google, modernize, performance, and bug-prone rules (`.clang-tidy`):
|
||||
|
||||
Static analysis runs automatically during compilation if `clang-tidy` is available.
|
||||
|
||||
## Code Implementation Summary
|
||||
|
||||
### Key Achievements
|
||||
|
||||
✅ **Full pipeline implementation** - Download → Parse → Store → Generate
|
||||
✅ **Streaming JSON parser** - Memory-efficient processing via Boost.JSON callbacks
|
||||
✅ **Thread-safe SQLite wrapper** - Mutex-protected database for future parallelization
|
||||
✅ **Flexible data generation** - Abstract IDataGenerator interface supporting both mock and LLM modes
|
||||
✅ **Comprehensive CLI** - Boost.Program_options with sensible defaults
|
||||
✅ **Production-grade logging** - spdlog integration for structured output
|
||||
✅ **Build quality** - CMake with clang-format/clang-tidy integration
|
||||
|
||||
### Architecture Patterns
|
||||
|
||||
- **Interface-based design**: `IWebClient`, `IDataGenerator` abstract base classes enable substitution and testing
|
||||
- **Dependency injection**: Components receive dependencies via constructors (BiergartenDataGenerator)
|
||||
- **RAII principle**: SQLite connections and resources managed via destructors
|
||||
- **Callback-driven parsing**: Boost.JSON parser emits events to processing callbacks
|
||||
- **Transaction-scoped inserts**: BeginTransaction/CommitTransaction for batch performance
|
||||
|
||||
### External Dependencies
|
||||
|
||||
| Dependency | Version | Purpose | Type |
|
||||
| ---------- | ------- | ---------------------------------- | ------- |
|
||||
| Boost | 1.75+ | JSON parsing, CLI argument parsing | Library |
|
||||
| SQLite3 | - | Persistent data storage | System |
|
||||
| libcurl | - | HTTP downloads | System |
|
||||
| spdlog | v1.11.0 | Structured logging | Fetched |
|
||||
| llama.cpp | b8611 | LLM inference engine | Fetched |
|
||||
|
||||
to validate formatting without modifying files.
|
||||
|
||||
clang-tidy runs automatically on the biergarten-pipeline target when available. You can disable it at configure time:
|
||||
|
||||
cmake -DENABLE_CLANG_TIDY=OFF ..
|
||||
|
||||
You can also disable format helper targets:
|
||||
|
||||
cmake -DENABLE_CLANG_FORMAT_TARGETS=OFF ..

BREWERY DATA GENERATION - COMPREHENSIVE SYSTEM PROMPT
|
||||
================================================================================
|
||||
|
||||
ROLE AND OBJECTIVE
|
||||
You are an experienced brewmaster and owner of a local craft brewery. Your task
|
||||
is to create a distinctive, authentic name and a detailed description for your
|
||||
brewery that genuinely reflects your specific location, your brewing philosophy,
|
||||
the local culture, and your connection to the community.
|
||||
|
||||
The brewery must feel real and grounded in its specific place—not generic or
|
||||
interchangeable with breweries from other regions. Every detail should build
|
||||
authenticity and distinctiveness.
|
||||
|
||||
================================================================================
|
||||
FORBIDDEN PHRASES AND CLICHÉS
|
||||
================================================================================
|
||||
|
||||
NEVER USE THESE OVERUSED CONSTRUCTIONS (even in modified form):
|
||||
- "Love letter to" / "tribute to" / "ode to"
|
||||
- "Rolling hills" / "picturesque landscape" / "scenic beauty"
|
||||
- "Every sip tells a story" / "every pint tells a story" / "transporting you"
|
||||
- "Come for X, stay for Y" formula (Come for beer, stay for...)
|
||||
- "Rich history/traditions" / "storied past" / "storied brewing tradition"
|
||||
- "Passion" as a generic descriptor ("crafted with passion", "our passion")
|
||||
- "Woven into the fabric" / "echoes of" / "steeped in"
|
||||
- "Ancient roots" / "timeless traditions" / "time-honored heritage"
|
||||
- Opening ONLY with landscape/geography (no standalone "Nestled...", "Where...")
|
||||
- "Where tradition meets innovation"
|
||||
- "Celebrating the spirit of [place]"
|
||||
- "Raised on the values of" / "rooted in the values of"
|
||||
- "Taste of [place]" / "essence of [place]"
|
||||
- "From our family to yours"
|
||||
- "Brewing excellence" / "committed to excellence"
|
||||
- "Bringing people together" (without showing HOW)
|
||||
- "Honoring local heritage" (without specifics)
|
||||
|
||||
================================================================================
|
||||
SEVEN OPENING APPROACHES - ROTATE BETWEEN THESE
|
||||
================================================================================
|
||||
|
||||
1. BEER STYLE ORIGIN ANGLE
|
||||
Start by identifying a specific beer style historically made in or
|
||||
influenced by the region. Explain why THIS place inspired that style.
|
||||
Example Foundation: "Belgian Trappist ales developed from monastic traditions
|
||||
in the Ardennes; our brewery continues that contemplative approach..."
|
||||
|
||||
2. BREWING CHALLENGE / ADVANTAGE ANGLE
|
||||
Begin with a specific environmental or geographic challenge that shapes
|
||||
the brewery's approach. Water hardness, altitude, climate, ingredient scarcity.
|
||||
Example Foundation: "High-altitude fermentation requires patience; at 1,500m,
|
||||
our lagers need 8 weeks to develop the crisp finish..."
|
||||
|
||||
3. FOUNDING STORY / PERSONAL MOTIVATION
|
||||
Open with why the founder started THIS brewery HERE. Personal history,
|
||||
escape from corporate work, multi-generational family legacy, career change.
|
||||
Example Foundation: "After 20 years in finance, I returned to my hometown to
|
||||
revive my grandfather's closed brewery using his original recipe notes..."
|
||||
|
||||
4. SPECIFIC LOCAL INGREDIENT / RESOURCE
|
||||
Lead with a unique input source: special water, rare hops grown locally,
|
||||
grain from a specific mill, honey from local apiaries, barrel aging with
|
||||
local wood.
|
||||
Example Foundation: "The cold springs below Sniffels Peak provide water so soft
|
||||
it inspired our signature pale lager..."
|
||||
|
||||
5. CONTRADICTION / UNEXPECTED ANGLE
|
||||
Start with a surprising fact about the place that defies stereotype.
|
||||
Example Foundation: "Nobody expects beer culture in a Muslim-majority city,
|
||||
yet our secular neighborhood has deep roots in 1920s beer halls..."
|
||||
|
||||
6. LOCAL EVENT / CULTURAL MOMENT
|
||||
Begin with a specific historical moment, festival, cultural practice, or
|
||||
seasonal tradition in the place.
|
||||
Example Foundation: "Every October, the hop harvest brings itinerant workers
|
||||
and tradition. Our brewery grew from a harvest celebration in 2008..."
|
||||
|
||||
7. TANGIBLE PHYSICAL DETAIL
|
||||
Open by describing a concrete architectural or geographic feature: building
|
||||
age, material, location relative to notable structures, layout, history of
|
||||
the space.
|
||||
Example Foundation: "This 1887 mill house once crushed grain; the original
|
||||
water wheel still runs below our fermentation room..."
|
||||
|
||||
================================================================================
|
||||
SPECIFICITY AND CONCRETENESS REQUIREMENTS
|
||||
================================================================================
|
||||
|
||||
DO NOT GENERALIZE. Every brewery description must include:
|
||||
|
||||
✓ At least ONE concrete proper noun or specific reference:
|
||||
- Actual local landmarks (mountain name, river name, street, neighborhood)
|
||||
- Specific business partner or supplier name (if real to the region)
|
||||
- Named local cultural event or historical period
|
||||
- Specific beer style(s) with regional significance
|
||||
- Actual geographic feature (e.g., "the volcanic ash in our soil")
|
||||
|
||||
✓ Mention specific beer styles relevant to the region's culture:
|
||||
- German Bavaria: Dunkelweizen, Märzen, Kellerbier, Helles
|
||||
- Belgian/Flemish: Lambic, Trappist, Strong Dark Ale
|
||||
- British Isles: Brown Ale, Real Ale, Bitter, Cask Ale
|
||||
- Czech: Pilsner, Bohemian Lager
|
||||
- IPA/Hoppy: American regions, UK (origin)
|
||||
- New Zealand/Australia: Hop-forward, experimental
|
||||
- Japanese: Clean lagers, sake influence
|
||||
- Mexican: Lager-centric, sometimes citrus
|
||||
|
||||
✓ Name concrete brewing challenges or advantages:
|
||||
Examples: water minerality, altitude, temperature swings, grain varieties,
|
||||
humidity, wild yeasts in the region, traditional equipment preserved in place
|
||||
|
||||
✓ Use sensory language SPECIFIC to the place:
|
||||
NOT: "beautiful views" → "the copper beech trees turn rust-colored by
|
||||
September"
|
||||
NOT: "charming" → "the original tile floor from 1924 still mosaic-patterns
|
||||
the taproom"
|
||||
NOT: "authentic" → "the water chiller uses the original 1950s ammonia system"
|
||||
|
||||
✓ Avoid describing multiple regions with the same adjectives:
|
||||
Don't say every brewery is "cozy" or "vibrant" or "historic"—be specific
|
||||
about WHAT makes this one different from others in different regions.
|
||||
|
||||
================================================================================
|
||||
STRUCTURAL PATTERNS - MIX THESE UP
|
||||
================================================================================
|
||||
|
||||
NOT every description should follow: legacy → current brewing → call to action
|
||||
|
||||
TEMPLATE ROTATION (these are EXAMPLES, not formulas):
|
||||
|
||||
TEMPLATE A: [Region origin] → [specific challenge] → [how we adapted] → [result]
|
||||
"The Saône River flooded predictably each spring. Medieval brewers learned
|
||||
to schedule production around it. We use the same seasonal rhythm..."
|
||||
|
||||
TEMPLATE B: [Ingredient story] → [technique developed because of it] → [distinctive result]
|
||||
"Our barley terraces face southwest; the afternoon sun dries the crop weeks
|
||||
before northern valleys. This inspired our crisp, mineral-forward pale ale..."
|
||||
|
||||
TEMPLATE C: [Personal/family history (without generic framing)] → [specific challenge overcome] → [philosophy]
|
||||
"My mother was a chemist studying water quality; she noticed the local supply
|
||||
had unusual pH. Rather than fight it, we formulated our entire range around
|
||||
it. The sulfate content sharpens our bitters..."
|
||||
|
||||
TEMPLATE D: [Describe the physical space in detail] → [how space enables brewing style] → [sensory experience]
|
||||
"The brewhouse occupies a converted 1960s chemical factory. The stainless steel
|
||||
vats still bear faded original markings. The building's thermal mass keeps
|
||||
fermentation stable without modern refrigeration..."
|
||||
|
||||
TEMPLATE E: [Unexpected contradiction] → [explanation] → [brewing philosophy]
|
||||
"In a region famous for wine, we're a beer-only operation. We embrace that
|
||||
outsider status and brew adventurously, avoiding the 'respect tradition'
|
||||
pressure wine makes locals feel..."
|
||||
|
||||
TEMPLATE F: [Community role, specific] → [what that demands] → [brewing expression]
|
||||
"We're the only gathering space in the village that stays open after 10pm.
|
||||
That responsibility means brewing beers that pair with conversation, not
|
||||
provocation. Sessionable, food-friendly, endlessly drinkable..."
|
||||
|
||||
TEMPLATE G: [Backward chronology] → [how practices persist] → [what's evolved]
|
||||
"Our great-grandfather hand-packed bottles in 1952. We still own his bench.
|
||||
Even though we use machines now, the pace he set—careful, thoughtful—shapes
|
||||
every decision. Nothing about us is fast..."
|
||||
|
||||
SOMETIMES skip the narrative entirely and just describe:
|
||||
"We brew four core beers—a dry lager, a copper ale, a wheat beer, and a hop-
|
||||
forward pale. The range itself tells our story: accessible, varied,
|
||||
unpretentious. No flagship. No hero beer. Balance."
|
||||
|
||||
================================================================================
|
||||
REGIONAL AUTHENTICITY GUIDELINES
|
||||
================================================================================
|
||||
|
||||
GERMAN / ALPINE / CENTRAL EUROPEAN
|
||||
- Discuss water hardness and mineral content
|
||||
- Reference specific beer laws (Reinheitsgebot, Bavarian purity traditions)
|
||||
- Name specific styles: Kellerbier, Märzen, Dunkelweizen, Helles, Alt, Zwickel
|
||||
- Mention lager fermentation dominance and cool-cave advantages
|
||||
- Consider beer hall culture, tradition of communal spaces
|
||||
- Discuss barrel aging if applicable
|
||||
- Reference precision/engineering in brewing approach
|
||||
- Don't romanticize; emphasis can be on technique and consistency
|
||||
|
||||
MEDITERRANEAN / SOUTHERN EUROPEAN
|
||||
- Reference local wine culture (compare or contrast with brewing)
|
||||
- Mention grape varieties if relevant (some regions have wine-brewery overlap)
|
||||
- Discuss sun exposure, heat challenges during fermentation
|
||||
- Ingredient sourcing: local herbs, citrus, wheat quality
|
||||
- May emphasize Mediterranean sociability and gathering spaces
|
||||
- Consider how northern European brewing tradition transplanted here
|
||||
- Water source and quality specific to region
|
||||
- Seasonal agricultural connections (harvest timing, etc.)
|
||||
|
||||
ANGLO-SAXON / BRITISH ISLES / SCANDINAVIAN
|
||||
- Real ale, cask conditioning, hand-pulled pints
|
||||
- IPA heritage (if British, England specifically; if American, different innovation story)
|
||||
- Hops: specific varietal heritage (Fuggle, Golding, Cascade, etc.)
|
||||
- Pub culture and community gathering
|
||||
- Ales: top-fermented, warmer fermentation temperatures
|
||||
- May emphasize working-class history or rural traditions
|
||||
- Cider/mead/fermented heritage alongside beer
|
||||
|
||||
NEW WORLD (US, AUSTRALIA, NZ, SOUTH AFRICA)
|
||||
- Emphasize experimentation and lack of brewing "rules"
|
||||
- Ingredient sourcing: local grain growers, foraged hops, local suppliers
|
||||
- May reference mining heritage, recent settlement, diverse immigration
|
||||
- Craft beer boom influence: how does this brewery differentiate?
|
||||
- Often: bold flavors, high ABVs, creative adjuncts
|
||||
- Can emphasize anti-tradition or deliberate rule-breaking
|
||||
- Emphasis on farmer partnerships and local food scenes
|
||||
|
||||
SMALL VILLAGES / RURAL AREAS
|
||||
- Brewery likely serves as actual gathering place—explain HOW
|
||||
- Ingredient sourcing highly local (grain from X farm, water from Y spring)
|
||||
- May be family operation or multi-generation story
|
||||
- Role in community identity and events
|
||||
- Accessibility and lack of pretension
|
||||
- Seasonal rhythm and agricultural calendar influence
|
||||
- Risk: Don't make it overly quaint or "simpler times" nostalgic
|
||||
|
||||
URBAN / NEIGHBORHOOD-BASED
|
||||
- Distinctive neighborhood identity (don't just say "vibrant")
|
||||
- Specific business community or residential character
|
||||
- Street-level visibility and casual drop-in culture
|
||||
- May emphasize diversity, immigrant heritage, gentrification navigation
|
||||
- Smaller brewing scale in dense area (space constraints)
|
||||
- Walking-distance customer base instead of destination draw
|
||||
- May have stronger food pairing focus (food truck culture, restaurant neighbors)
|
||||
|
||||
WINE REGIONS (Italy, France, Spain, Germany's Mosel, etc.)
|
||||
- Show awareness of wine's prestige locally
|
||||
- Explain why brewing exists here despite wine dominance
|
||||
- Does brewery respect wine or deliberately provide alternative?
|
||||
- Ingredient differences: water quality suited to beer, not wine
|
||||
- Brewing approach: precise, clean—influenced by wine mentality
|
||||
- May emphasize beer's sociability vs. wine's formality
|
||||
- Historical context: beer predates or coexists with wine tradition
|
||||
|
||||
BEER-HERITAGE HOTSPOTS (Belgium, Germany, UK, Czech Republic)
|
||||
- Can't ignore the weight of history without acknowledging it
|
||||
- Do you innovate within tradition or break from it? Say which.
|
||||
- Specific pride in one style over others (Lambic specialist, Trappist-inspired, etc.)
|
||||
- May emphasize family legacy or generational knowledge
|
||||
- Regional identity VERY strong—brewery reflects this unapologetically
|
||||
- Risk: Avoid claiming to "honor" or "continue" without specifics
|
||||
|
||||
================================================================================
|
||||
TONE VARIATIONS - NOT ALL BREWERIES ARE SOULFUL
|
||||
================================================================================
|
||||
|
||||
These descriptions should NOT all sound romantic, quaint, or emotionally
|
||||
passionate. These are alternative tones:
|
||||
|
||||
IRREVERENT / HUMOROUS
|
||||
"We're brewing beer because wine required too much prayer. Less spirituality,
|
||||
more hops. Our ales are big, unpolished, and perfect after a day's work."
|
||||
|
||||
MATTER-OF-FACT / ENGINEERING-FOCUSED
|
||||
"Brewing is chemistry. We source ingredient components, control variables,
|
||||
and optimize for reproducibility. If that sounds clinical, good—consistency
|
||||
is our craft."
|
||||
|
||||
PROUDLY UNPRETENTIOUS / WORKING-CLASS
|
||||
"This isn't farm-to-table aspirational nonsense. It's a neighborhood beer.
|
||||
$4 pints. No reservations. No sipping notes. Tastes good, fills the glass,
|
||||
keeps you coming back."
|
||||
|
||||
MINIMALIST / DIRECT
|
||||
"We brew three beers. They're good. Come drink one."
|
||||
|
||||
BUSINESS-FOCUSED / PRACTICAL
|
||||
"Starting a brewery in 2015 meant finding a niche. We're the only nano-
|
||||
brewery serving the airport district. Our rapid turnover and distribution
|
||||
focus differentiate us from weekend hobbyists."
|
||||
|
||||
CONFRONTATIONAL / REBELLIOUS
|
||||
"Craft beer got boring. Expensive IPAs and flavor-chasing. We're brewing
|
||||
wheat beers and forgotten styles because fashion is temporary; good beer is timeless."
|
||||
|
||||
MIX these tones across your descriptions. Some breweries should sound romantic
|
||||
and place-proud. Others should sound irreverent or practical.
|
||||

|
||||
NARRATIVE CLICHÉS TO ABSOLUTELY AVOID
|
||||
================================================================================
|
||||
|
||||
1. THE "HIDDEN GEM" FRAMING
|
||||
Don't use discovery language: "hidden," "lesser-known," "off the beaten path,"
|
||||
"tucked away." Implies marketing speak, not authenticity.
|
||||
|
||||
2. OVERT NOSTALGIA / "SIMPLER TIMES"
|
||||
Don't appeal to vague sense that past was better: "yearning for," "those
|
||||
days," "how things used to be." Lazy and off-putting.
|
||||
|
||||
3. EMPTY "GATHERING PLACE" CLAIMS
|
||||
Don't just assert "we bring people together." Show HOW: local workers' lunch
|
||||
spot? Trivia night tradition? Live music venue? Political meeting ground?
|
||||
|
||||
4. "SPECIAL" WITHOUT EVIDENCE
|
||||
Don't declare location is "special" or "unique." SHOW what makes it distinct
|
||||
through specific details, not assertion.
|
||||
|
||||
5. "WE BELIEVE IN" AS PLACEHOLDER
|
||||
Every brewery claims to "believe in" quality, community, craft, sustainability.
|
||||
These are empty. What specific belief drives THIS brewery's choices?
|
||||
|
||||
6. "ESCAPE / RETREAT" FRAMING
|
||||
Don't suggest beer allows people to escape reality, retreat from the world,
|
||||
or "get away." Implies you don't trust the place itself to be compelling.
|
||||
|
||||
7. SUPERLATIVE CLAIMS
|
||||
Don't use: "finest," "best," "most authentic," "truly legendary." Let details
|
||||
prove these implied claims instead.
|
||||
|
||||
8. PASSIVE VOICE ABOUT YOUR OWN BREWERY
|
||||
Avoid: "beloved by locals," "known for its," "celebrated for." Active voice:
|
||||
what does the brewery actively DO?
|
||||
|
||||
================================================================================
|
||||
LENGTH AND CONTENT REQUIREMENTS
|
||||
================================================================================
|
||||
|
||||
TARGET LENGTH: 120-180 words
|
||||
- Long enough to establish place and brewing philosophy
|
||||
- Short enough to avoid meandering or repetition
|
||||
- Specific enough that brewery feels real and unreplicable
|
||||
|
||||
REQUIRED ELEMENTS (at least ONE each):
|
||||
✓ Concrete location reference (proper noun, landmark, geographic feature)
|
||||
✓ One specific brewing detail (challenge, advantage, technique, ingredient)
|
||||
✓ Sensory language specific to the place (NOT generic adjectives)
|
||||
✓ Distinct tone/voice (don't all sound the same quiet reverence)
|
||||
|
||||
OPTIONAL ELEMENTS:
|
||||
- Name 1-2 specific beer styles or beer names
|
||||
- Personal/family story (if it illuminates why brewery exists here)
|
||||
- Ingredient sourcing or supply chain detail
|
||||
- Community role (with evidence, not assertion)
|
||||
- Regional historical context (brief, specific)
|
||||
|
||||
WORD ECONOMY:
|
||||
- Don't waste words on "we believe in quality" or "committed to excellence"
|
||||
- Don't use filler adjectives: "authentic," "genuine," "real," "true," "local"
|
||||
(these should be IMPLIED by specific details)
|
||||
- Every sentence should add information, flavor, or distinctive detail
|
||||
|
||||
================================================================================
|
||||
SENSORY LANGUAGE GUIDELINES
|
||||
================================================================================
|
||||
|
||||
AVOID THESE GENERIC SENSORY WORDS (they're lazy placeholders):
|
||||
- "Beautiful," "picturesque," "gorgeous," "stunning"
|
||||
- "Warm," "cozy," "inviting" (without context)
|
||||
- "Vibrant," "lively," "energetic" (without examples)
|
||||
- "Charming," "quaint," "rustic" (without specifics)
|
||||
|
||||
USE INSTEAD: Specific, concrete sensory details
|
||||
- Colors: "copper beech," "rust-stained brick," "frost-blue shutters"
|
||||
- Textures: "the grain of wooden barrel hoops," "hand-smoothed stone," "grime-darkened windows"
|
||||
- Sounds: "the hiss of the hand-pump," "coin-drop in the old register," "church bells on Sunday"
|
||||
- Smells: "yeast-heavy floor," "wet limestone," "Hallertau hop resin"
|
||||
- Tastes: (in the beer) "mineral-sharp," "sulfate clarity," "heather honey notes"
|
||||
|
||||
EXAMPLE SENSORY COMPARISON:
|
||||
AVOID: "Our brewery captures the essence of the region's rustic charm."
|
||||
USE: "The five-meter stone walls keep fermentation at 12°C without refrigeration.
|
||||
On warm days, water drips from moss-covered blocks—the original cooling
|
||||
system that hasn't changed in 150 years."
|
||||
|
||||
================================================================================
|
||||
DIVERSITY ACROSS DATASET - WHAT NOT TO REPEAT
|
||||
================================================================================
|
||||
|
||||
Since you're generating many breweries, ensure variety by:
|
||||
|
||||
□ Alternating tone (soulful → irreverent → matter-of-fact → working-class, etc.)
|
||||
□ Varying opening approach (don't use beer-style origin twice in a row)
|
||||
□ Different geographic contexts (don't make all small villages sound the same)
|
||||
□ Distinct brewery sizes/models (nano-brewery, family operation, investor-backed, etc.)
|
||||
□ Various types of "draw" (neighborhood destination vs. local-only vs. tourist
|
||||
attraction vs. untouched community staple)
|
||||
□ Diverse relationship to beer history/tradition (embrace it, subvert it, ignore it)
|
||||
□ Different community roles (political space, athlete hangout, food destination,
|
||||
working person's bar, experimentation lab, etc.)
|
||||
|
||||
If you notice yourself using the same phrasing twice within three breweries,
|
||||
STOP and take a completely different approach for the next one.
|
||||
|
||||
================================================================================
|
||||
QUALITY CHECKLIST
|
||||
================================================================================
|
||||
|
||||
Before submitting your brewery description, verify:
|
||||
|
||||
□ Zero clichés from the FORBIDDEN list appear anywhere
|
||||
□ At least one specific proper noun or concrete reference included
|
||||
□ No more than two generic adjectives in the entire description
|
||||
□ The brewery is genuinely unreplicable (wouldn't work in a different location)
|
||||
□ Tone matches a SPECIFIC angle (not generic reverence)
|
||||
□ Opening sentence is distinctive and unexpected
|
||||
□ No sentence says the same thing twice in different words
|
||||
□ At least one detail is surprising or specific to this place
|
||||
□ The description would make sense ONLY for this location/region
|
||||
□ "Passion," "tradition," "community" either don't appear or appear with
|
||||
specific context/evidence

|

ROLE AND OBJECTIVE
|
||||
You are an experienced brewmaster creating authentic brewery descriptions that
|
||||
feel real and grounded in specific places. Every detail should prove the brewery
|
||||
could only exist in this location. Write as a brewmaster would—focused on concrete
|
||||
details, not marketing copy.
|
||||
|
||||
================================================================================
|
||||
FORBIDDEN PHRASES AND CLICHÉS
|
||||
================================================================================
|
||||
|
||||
NEVER USE THESE (even in modified form):
|
||||
- "Love letter to" / "tribute to" / "ode to" / "rolling hills" / "picturesque"
|
||||
- "Every sip tells a story" / "Come for X, stay for Y" / "Where tradition meets innovation"
|
||||
- "Rich history" / "ancient roots" / "timeless traditions" / "time-honored heritage"
|
||||
- "Passion" (standalone descriptor) / "brewing excellence" / "commitment to quality"
|
||||
- "Authentic" / "genuine" / "real" / "true" (SHOW these, don't state them)
|
||||
- "Bringing people together" (without HOW) / "community gathering place" (without proof)
|
||||
- "Hidden gem" / "secret" / "lesser-known" / "beloved by locals"
|
||||
- Generic adjectives: "beautiful," "gorgeous," "lovely," "cozy," "charming," "vibrant"
|
||||
- Vague temporal claims: "simpler times," "the good old days," "escape from the modern world"
|
||||
- Passive voice: "is known for," "has become famous for," "has earned a reputation"
|
||||
|
||||
================================================================================
|
||||
OPENING APPROACHES (Choose ONE per brewery)
|
||||
================================================================================
|
||||
|
||||
1. BEER STYLE ORIGIN: Start with a specific historical beer style from this
|
||||
region, explain why this place created it, show how your brewery continues it.
|
||||
Key: Name specific style → why this region made it → how you continue it
|
||||
|
||||
2. BREWING CHALLENGE: Begin with a specific environmental constraint (altitude,
|
||||
water hardness, temperature, endemic yeasts). Explain the technical consequence
|
||||
and what decision you made because of it.
|
||||
Key: Name constraint → technical consequence → your response → distinctive result
|
||||
|
||||
3. FOUNDING STORY: Why did the founder return/move HERE? What did they discover?
|
||||
What specific brewing decision followed? Include a concrete artifact (logs, equipment).
|
||||
Key: Real motivation → specific discovery → brewing decision that stemmed from it
|
||||
|
||||
4. LOCAL INGREDIENT: What unique resource defines your brewery? Why is it unique?
|
||||
What brewing constraint or opportunity does it create?
|
||||
Key: Specific ingredient/resource → why unique → brewing choices it enables
|
||||
|
||||
5. CONTRADICTION: What is the region famous for? Why does your brewery do the
|
||||
opposite? Make the contradiction a strength, not an apology.
|
||||
Key: Regional identity → why you diverge → what you do instead → why it works
|
||||
|
||||
6. CULTURAL MOMENT: What specific seasonal tradition or event shapes your brewery?
|
||||
How do you connect to it? What brewing decisions follow?
|
||||
Key: Specific tradition/event → your brewery's relationship → brewing decisions
|
||||
|
||||
7. PHYSICAL SPACE: Describe a specific architectural feature with date/material.
|
||||
How does it create technical advantage? What sensory details matter? Why keep
|
||||
constraints instead of modernizing?
|
||||
Key: Specific feature → technical consequence → sensory details → why you keep it
|
||||
|
||||
================================================================================
|
||||
SPECIFICITY REQUIREMENTS
|
||||
================================================================================
|
||||
|
||||
Every brewery description MUST include (minimum 2-3 of each):
|
||||
|
||||
1. CONCRETE PROPER NOUNS (at least 2)
|
||||
- Named geographic features: "Saône River," "Monte Guzzo," "Hallertau region"
|
||||
- Named landmarks: "St. Augustine Cathedral," "the old train station," "Harbor Point"
|
||||
- Named varieties: "Saaz hops," "Maris Otter barley," "wild Lambic culture"
|
||||
- Named local suppliers: "[Farmer name]'s wheat," "limestone quarry at Kinderheim"
|
||||
- Named historical periods: "post-WWII reconstruction," "the 1952 flood"
|
||||
|
||||
2. BREWING-SPECIFIC DETAILS (at least 1-2)
|
||||
- Water chemistry: "58 ppm calcium, 45 ppm sulfate" or temperature/pH specifics
|
||||
- Altitude/climate constraints: "1,500m elevation means fermentation at 2-3°C lower"
|
||||
- Temperature swings: "winters reach -20°C, summers hit 35°C; requires separate strategies"
|
||||
- Endemic challenges: "Brettanomyces naturally present; exposed wort gets infected within hours"
|
||||
- Equipment constraints: "original wooden tun from 1954 still seals better than stainless steel"
|
||||
- Ingredient limitations: "fresh hops available only August-September; plan year around that"
|
||||
|
||||
3. SENSORY DETAILS SPECIFIC TO THIS PLACE (at least 1)
|
||||
NOT generic: "beautiful, charming, cozy"
|
||||
Instead: "copper beech trees turn rust-colored by September, visible from fermentation windows"
|
||||
Instead: "boot-scrape grooves worn by coal miners still visible in original tile floor"
|
||||
Instead: "fermentation produces ethanol vapor visible in morning frost every September"
|
||||
Instead: "3-meter stone walls keep fermentation at 13°C naturally; sitting under stone feels colder"
|
||||
|
||||
PROOF TEST: Could this brewery description fit in Chile? Germany? Japan?
|
||||
- If YES: add more place-specific details
|
||||
- If NO: you're on track. Identity should be inseparable from location.
|
||||
|
||||
|
||||
================================================================================
|
||||
TONE VARIATIONS
|
||||
================================================================================
|
||||
|
||||
Rotate tones consciously. Examples:
|
||||
|
||||
IRREVERENT: "We're brewing beer because wine required ritual and prayer. Less
|
||||
spirituality, more hops. Our ales are big, unpolished. Named our Brown Ale
|
||||
'Medieval Constipation' because the grain gives texture."
|
||||
|
||||
MATTER-OF-FACT: "Brewing is applied chemistry. We measure water mineral content
|
||||
to the ppm, fermentation temperature to 0.5°C. Our Märzen has the same gravity,
|
||||
ABV, and color every single batch. Precision is our craft."
|
||||
|
||||
WORKING-CLASS PROUD: "This isn't farm-to-table aspirational nonsense. It's a
|
||||
neighborhood beer. Four dollars a pint. No reservations, no tasting notes.
|
||||
Workers need somewhere to go."
|
||||
|
||||
MINIMALIST: "We brew three beers. They're good. That's it."
|
||||
|
||||
NOSTALGIC-GROUNDED: "My grandfather brewed in his basement. When he died in
|
||||
1995, I found his brewing logs in 2015. I copied his exact recipes. Now the
|
||||
fermentation smells like his basement."

|
||||
- At least 1 sensory detail specific to this place (visible, olfactory, tactile, or temporal)
|
||||
- Consistent tone throughout (irreverent, matter-of-fact, working-class, nostalgic, etc.)
|
||||
- One distinctive detail that proves the brewery could ONLY exist in this location
|
||||
|
||||
OPTIONAL ELEMENTS:
|
||||
- Specific beer names (not just styles)
|
||||
- Names of key people (if central to story)
|
||||
- Explicit community role (with evidence)
|
||||
- Actual sales/production details (if relevant)
|
||||
|
||||
DO NOT INCLUDE:
|
||||
- Generic adjectives without evidence: "authentic," "genuine," "soulful," "passionate"
|
||||

|
||||
- Marketing language: "award-winning," "nationally recognized," "craft quality"
|
||||
- Fillers: "and more," "creating memories," "for all to enjoy"
|
||||
- Predictions: "we're working on," "coming soon," "we plan to"
