Brewers Almanack

A brewing knowledge MCP server: beer styles, ingredients, off-flavour diagnosis, water chemistry, and recipe guidance for AI assistants.

Ask your AI assistant about beer styles, diagnose off-flavours, build recipes, match water profiles, and pair food (all backed by real brewing data, not hallucinations).

6 tools. Zero config. Works with every MCP-compatible IDE.

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 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.
