Angel Yeast KO is a specialized top-fermenting strain ideal for Kölsch-style beers and clean hybrid ales. It produces a soft, neutral base that allows subtle hops and malt character to shine, while releasing light fruity esters at warmer temperatures. Medium-to-high flocculation promotes clarity, and its strong β-glucosidase activity enhances hop biotransformation—ideal for dry-hopped blonde ales or modern Kölsch interpretations. KO ferments clean at cool ale temps but can flex into warmer regimes with minimal off-flavors.

• Neutral, lager-like ale profile with restrained esters

• Medium-to-high flocculation for bright, polished beers

• Attenuation range of 78–83% for a crisp, dry finish

• Ferments from 59–77 °F (15–25 °C); cooler for classic Kölsch, warmer for esters

• High β-glucosidase activity for enhanced hop biotransformation

• Alcohol tolerance up to 9% ABV

Fermentation Range:
 59–77 °F (15–25 °C)
Recommended for classic Kölsch: 59–64 °F (15–18 °C)

Usage Rate:
0.5–1.0 g/L (50–100 g/hL); increase to 1.5–2.0 g/L (150–200 g/hL) for high-gravity or heavily dry-hopped beers

Rehydration Instructions:
Rehydrate in 5–10× its weight of clean water or diluted wort at 72–86 °F (22–30 °C) for 10–20 minutes. Gently adjust to wort temperature and pitch within 30 minutes for optimal viability.

Applications:
Kölsch • Blonde Ale • Cream Ale • California Common • Hybrid Fermentations
