What problem does it solve? Brewers struggle to choose the right hop varieties, addition timings, and quantities for a target beer style, and often miscalculate substitutions when a hop is unavailable. This reference consolidates flavor profiles, pairing rules, and dosing guidelines for over 40 hop varieties into one decision-ready resource. ## Core Features & Use Cases - Hop Flavor Profiles: Tables of 40+ varieties organized by flavor category (citrus/tropical, resinous, noble, English, high-alpha bittering) with origin, alpha acid range, and usage role. - Style-Based Pairing Guide: Bittering, flavor, and dry hop recommendations for American IPAs, NEIPAs, lagers, Belgian ales, English ales, and stouts, including which hops to avoid per style. - Dry Hop Rates & Techniques: Total g/L dosing guidelines by intensity, Cryo hop conversion rules, and biotransformation dry hopping technique with recommended yeasts and timing. - Substitution Formula: Alpha-acid ratio formula to compute equivalent bittering weight when swapping varieties, with caveats for aroma-only additions. - Use Case: When designing a hazy IPA, look up the NEIPA section to select a Citra + Mosaic dry hop combo, dose it at 15–25 g/L split across a biotransformation charge and a cold-side charge, and substitute Galaxy for Citra using the AA ratio if needed. ## Quick Start Ask the agent to recommend a hop schedule for a New England IPA using Citra and Mosaic with biotransformation dry hopping.
