Recommended for American Pale Ale, IPA, Blonde Ale, Amber, Brown, Porter, and Stout
Ferment between 59-77°F
Angel Yeast A01 is a clean-fermenting American ale strain ideal for a wide range of hop-forward and malt-balanced styles. It delivers a crisp, neutral profile with low ester production, allowing hops and specialty malts to take center stage. With strong attenuation and medium-to-high flocculation, A01 produces bright, well-finished beers that require little intervention to clarify.
A01 performs well across a broad temperature range and is suitable for a variety of ales including American Pale Ale, IPA, Amber, Blonde, Brown, and even Stout. It is POF-negative, non-diastatic, and offers fast, consistent fermentation—making it a highly reliable choice for both commercial and home brewers.

Excellent for a wide range of American ale styles
POF-negative and non-diastatic
Alcohol tolerance up to 10% ABV
Fermentation Range:
59–77°F (15–25°C)
Recommended range for cleanest profile: 59–68°F (15–20°C)
Usage Rate:
0.5–1.0 g/L depending on wort gravity and fermentation temperature
Typical pitch rate: 50–100 g/hL for standard-strength ales
Rehydration Instructions:
For best results, rehydrate yeast in clean water at 86°F (30°C) for 15 minutes before pitching. While direct pitching is possible, rehydration is strongly recommended for high-gravity fermentations or when yeast health is critical.
