Summary
Wraps comprehensive brewing reference data into six tools your AI can query directly. Search 85 BJCP beer styles with vital stats and commercial examples, diagnose 25 off-flavors with causes and prevention steps, look up 113 hops plus malts and yeasts with substitutes and characteristics, match water profiles by city or style, generate complete recipes with grain bills and hop schedules, and get beer and food pairings. All data is embedded, so there's no network dependency or API keys. Reach for this when you're recipe planning, troubleshooting a batch, or need brewing chemistry details without leaving your editor. Built on BJCP 2021 guidelines, published maltster specs, and brewing science literature.
On Capafy, your Skill runs online 24/7 as an agent product, and you get paid every time someone uses it.

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.
Install

Tools
| Tool | Description |
|---|---|
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. |
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).
