Overview
BrewCodex (formerly Brew Alchemy) started as a way to keep better brewing data close at hand. It has grown into a database and set of tools for comparing ingredients, testing recipes, and exploring the more technical side of brewing.
Brewing Data & Databases
Comprehensive information about brewing ingredients with scientific normalization and technical specifications:
- Hop Varieties (200+): Alpha/beta acids, oil content, and detailed aroma/flavor descriptors
- Yeasts & Cultures (150+): Attenuation, flocculation, temperature ranges, and alcohol tolerance
- Fermentables: Malts, sugars, and other fermentable ingredients with extraction potential
- Water Chemistry: Water profiles and their impact on different beer styles
- Beer Styles (100+): Guidelines categorized by ABV, IBU, and color standards
- Fermentation: Fermentation processes and parameters
Specialized Brewing Tools
Purpose-built calculators and comparison wizards to simplify complex brewing decisions:
- Hop Comparison Wizard: Compare multiple hop varieties side-by-side with detailed acid profiles and flavor characteristics
- Hop Substitution Wizard: Find the perfect substitute for any hop based on similar characteristics and flavor profiles
- Yeast Comparison Wizard: Compare yeast strains across manufacturers with attenuation, flocculation, and flavor notes
- Yeast Starter Calculator: Calculate the optimal starter size for your yeast based on gravity and batch size
- Carbonation Calculator: Determine the right amount of priming sugar for bottle conditioning based on style and temperature
- ABV Calculator: Calculate alcohol by volume from original and final gravity readings
- Gravity Calculator: Calculate fermentable amounts, water additions, and blend batches to hit your target gravity
