What problem does it solve? Brewers designing or refining beer recipes need accurate style targets for gravity, bitterness, color, water chemistry, and ingredients, and this reference supplies those BJCP-aligned specifications in one place. ## Core Features & Use Cases - Style Specifications: OG, FG-relevant ABV, IBU, and SRM ranges for 37 styles across lagers, ales, porters, stouts, wheat beers, and Belgian ales. - Ingredient Guidance: Recommended base malts, specialty malts, hop varieties, and yeast strains with attenuation and fermentation temperature notes. - Water & Serving Profiles: Calcium, sulfate, and chloride targets plus carbonation volumes and serving temperatures per style. - Flaw Diagnosis: Common off-flavor causes per style, such as DMS in lagers, oxidation in IPAs, and diacetyl in English bitters. - Use Case: When designing a Hazy IPA, look up the style to get the 1:3 sulfate-to-chloride water ratio, oat and wheat grist percentages, and low-bittering dry-hop guidance. ## Quick Start Ask the agent to design a recipe for a specific beer style, such as a German Pilsner, and it will apply the style's gravity, hop, water, and yeast specifications.
