What You'll Find on BeerFYI

BeerFYI is a comprehensive beer reference covering 112 beer styles, 82 hop varieties, 41 malts, 29 yeast strains, and 150 expert guides. The database follows the Beer Judge Certification Program (BJCP) style guidelines -- the global standard for beer style classification used in homebrewing competitions and professional brewing.

Beer Style Categories

Beer styles are organized into broad families based on fermentation method, yeast type, and regional brewing traditions. Each style has defined parameters for appearance, aroma, flavor, and mouthfeel:

Category	Description	Notable Styles
Ale	Top-fermented, warm fermentation (15-24C)	Pale Ale, IPA, Stout, Porter, Belgian Tripel
Lager	Bottom-fermented, cold conditioning (7-13C)	Pilsner, Helles, Bock, Dunkel, Marzen
Wheat	Significant wheat malt proportion (30-70%)	Hefeweizen, Witbier, Berliner Weisse
Stout	Roasted barley, dark color, rich body	Dry Stout, Imperial Stout, Milk Stout, Oatmeal Stout
IPA	Hop-forward, American craft innovation	West Coast IPA, New England IPA, Double IPA, Session IPA
Sour	Intentional acidity from wild yeast/bacteria	Lambic, Gose, Flanders Red, Kettle Sour
Belgian	Complex yeast character, phenols, esters	Dubbel, Tripel, Quadrupel, Saison, Witbier
Wild/Spontaneous	Open-air inoculation, Brettanomyces	Lambic, Gueuze, American Wild Ale

BeerFYI catalogs 82 hop varieties with detailed profiles including alpha acid percentage, aroma descriptors, typical usage (bittering, flavor, aroma, dry-hop), and recommended beer styles. Hops provide bitterness to balance malt sweetness, contribute floral, citrus, pine, or tropical aromas, and act as a natural preservative.

Major hop-growing regions include the Pacific Northwest (Yakima Valley), Germany (Hallertau, Tettnang), England (Kent), Czech Republic (Saaz), and New Zealand (Nelson). Each region's terroir influences hop character -- Cascade from Yakima delivers different citrus notes than Cascade grown in other regions.

Malts and Grains

The 41 malts in the database cover base malts (Pale, Pilsner, Munich, Vienna), specialty malts (Crystal, Caramel, Chocolate, Black Patent), and adjuncts (wheat, oats, rye, corn, rice). Malt provides fermentable sugars, body, color (measured in SRM/Lovibond), and flavor complexity.

The malting process -- steeping, germination, and kilning -- transforms raw barley into brewing malt. Temperature and duration of kilning determine color and flavor: light kilning produces pale malt (2-4 SRM), moderate kilning creates Munich malt (8-10 SRM), and high-temperature roasting yields chocolate malt (350-450 SRM).

Yeast Strains

BeerFYI tracks 29 yeast strains with fermentation temperature ranges, attenuation percentages, flocculation characteristics, and flavor contributions. Yeast is the most influential ingredient in beer -- the same wort fermented with different yeast strains produces fundamentally different beers.

Major yeast categories include clean ale strains (American, English), expressive Belgian strains (Abbey, Saison), clean lager strains (Bohemian, Bavarian), and wild cultures (Brettanomyces, Lactobacillus, Pediococcus).
