Angel Yeast CS31 is a robust, high-performance Belgian Saison ale yeast known for its fruity ester expression, vigorous fermentation, and ability to produce very dry, highly attenuated beers. A diastatic strain (STA1+), CS31 delivers the classic Saison character peppery, fruity, and crisp while tolerating high alcohol levels and finishing reliably.

• Fruity, ester-forward Belgian Saison profile with dry finish

• Medium-to-high flocculation for bright, refined beer

• Very high attenuation (~83–94%) for crisp, dry styles

• Ferments well between 59–77 °F (15–25 °C); ideal at 64–72 °F (18–22 °C)

• Diastatic (STA1+) for full, dry fermentation

• Alcohol tolerance up to 14% ABV

Fermentation Range:
59–77 °F (15–25 °C)
Recommended for precision brewing: 64–72 °F (18–22 °C)

Usage Rate:
0.5–1.0 g/L (50–100 g/hL); increased pitching of 1.5–3.0 g/L (150–300 g/hL) advised for high-gravity or challenging fermentations

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 half an hour to ensure optimal yeast vitality.

Applications:
Saison • Belgian Blond • Tripel • Strong Golden Ale • High-Gravity Belgian Ales
