About
A clean American ale dry yeast and one of the most reliable, forgiving and widely available strains in homebrewing. It ferments with low ester production and good attenuation, leaving a neutral background that lets hops and malt do the talking. Its wide temperature tolerance and ease of use make it the standard choice for a huge range of American and modern styles.

Brewing tips
- Lag is typically 12–24 hours; an overnight start is normal.
- Minimal ester increase across its range, so it stays clean even at the warmer end.
- Low pressure tolerance — not suited to pressure fermentation above 1–2 PSI.
- Ferment cool (15–16°C) for a clean, lager-adjacent American profile.
Handling & storage
- Rehydration
- Rehydrate in water 15 min at 20–25°C, or direct-pitch (≈85% viability direct).
- Storage
- 2–8°C ideal; room temperature acceptable short-term (1–2 months).
- Shelf life
- 1–2 years if kept cool; check the date code. Viability drops ~10% per 6 months at room temp.
