Angel A01 American Ale Yeast

Angel A01 is typical American ale yeast with a clean, neutral, and crisp profile, producing low fruity esters. This yeast has wide adaptability for many kinds of American styles, highlighting the characteristics and style of malt and hops.

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.

Fermentation Profile

Usage

Dosage: 50 to 100 g/hl, increasing yeast dosage under difficult fermentation conditions and high gravity.

Rehydration method:

1. Rehydrate the yeast in 10 times its weight of clean boiled water at 25-30℃ in a sterile container.

2. Ensure all the yeast contact with water, leave it for 15 minutes and then gently stir to suspend yeast completely and rehydrate fully. Leave it for another 5 minutes at 25-30℃.

3. The rehydration process does not exceed 30 minutes. If it is above 30 minutes, yeast viability will be hurt.

4. Pitch the rehydration yeast into the fermentation vessel. The temperature difference between the wort to be inoculated and the rehydration yeast should never be over 10°C.

Storage

Store in low temperature (≤10℃) and dry place, with the shelf life of 24 months.
