Angel Yeast AW-19 is built for grain-based whisky fermentations that demand strength and reliability. With exceptional tolerance to alcohol, heat, and acidic conditions, AW-19 ensures fast, complete fermentation while producing a clean and neutral spirit base. Perfect for bourbon, corn whisky, or high-gravity neutral washes where yield and consistency are critical.
-
High alcohol tolerance with strong stress resistance
-
Clean, low-ester profile for neutral or light grain spirits
-
Fast attenuation and robust kinetics, even in high-gravity or hot ferments
-
Performs well in corn, wheat, or mixed-grain mashes
-
Living yeast cells ≥ 10 billion cfu/g; moisture ≤ 7%; high apparent fermentation rate
Fermentation Range
72–90 °F (22–32 °C)
Usage Rate
0.5–1.0 g per liter (0.5–1.0 kg per 1000 kg mash/wash)
Instructions
Rehydrate in 5–10× its weight of clean water or low-strength wort at 22–30 °C for 7–15 minutes. Stir gently, rest for another 10–15 minutes, then pitch into the fermenter at 28–32 °C. Typical fermentation completes in 3–7 days depending on substrate and gravity.
Applications
Bourbon • Corn Whisky • Wheat Whisky • Neutral Grain Spirits • High-Gravity Ferments
