## Description
A brewing knowledge MCP server with beer styles (BJCP 2021), 113 hop varieties, malts, yeasts, water profiles, off-flavour diagnosis, recipe suggestions, and food pairings.

## Tools
Capabilities this server exposes over MCP:

- **search_styles** — Search 85 BJCP beer styles by name, category, or characteristics. Returns vital statistics, overall impression, ingredients, and commercial examples.
- **search_ingredients** — Search hops, malts, yeasts, and adjuncts by name, type, or characteristic. Filter by category or search across all.
- **diagnose_off_flavour** — Identify off-flavours from taste or aroma descriptions. Returns the likely compound, causes, prevention steps, and styles where it may be acceptable.
- **match_water_profile** — Find brewing water profiles by city name or beer style. Returns mineral composition (Ca, Mg, Na, Cl, SO4, HCO3) and style recommendations.
- **suggest_recipe** — Generate a recipe for a target beer style. Returns grain bill, hop schedule, yeast selection, water profile, and process parameters.
- **pairing_guide** — Beer and food pairing suggestions. Search by beer style or dish name. Returns matches with complement, contrast, and cleanse principles.

## Claude Desktop Quick Installation

## Example Conversations

**"What hops work in a Belgian Dubbel?"**
> Searches ingredients for hops that complement Belgian styles, returning varieties like Styrian Goldings and Saaz with alpha acid ranges, aromas, and substitutes.

**"My beer tastes like butter, what went wrong?"**
> Diagnoses diacetyl: identifies the compound, explains causes (incomplete fermentation, premature racking), and gives prevention steps (diacetyl rest, healthy yeast pitch).

**"Suggest a recipe for a West Coast IPA"**
> Builds a complete recipe: pale malt base with crystal malt, Centennial/Cascade hop schedule with dry hop additions, American ale yeast, and a Burton-style water profile.

**"What food pairs well with a stout?"**
> Returns pairing suggestions (oysters, chocolate desserts, grilled meats) with principles explaining why each pairing works (complement, contrast, or cleanse).

## Roadmap

See [ROADMAP.md](https://github.com/gregario/brewers-almanack/blob/HEAD/ROADMAP.md) for planned features: brewing calculators, recipe intelligence, BeerXML/BeerJSON integration, and a brewing journal.

## Contributing

Contributions are welcome, especially data contributions. More hop varieties, yeast strains, regional water profiles, and food pairings make the server more useful for everyone.

```bash
git clone https://github.com/gregario/brewers-almanack.git
cd brewers-almanack
npm install
npm run build
npm test        # 73 tests
