Safale US-05 is a quintessential dry American Ale strain that produces well-balanced beers with low diacetyl and a clean, crisp palate.
This strain forms a firm foam head and has the ability to stay in suspension during fermentation. It’s particularly well-suited for American beer types and highly hopped beers. The fermentation properties of Safale US-05 are similar to those of Wyeast 1056 (American Ale) or White Labs WLP001 (California Ale). Sedimentation is low to medium, and the final gravity is medium.
- Forms a firm foam head
- Good ability to stay in suspension during fermentation
- Ideal for American beer types and highly hopped beers

Pitch Rate / Dosage Instructions
50 to 80 g/100 litres (10g – 16g per 20L)
Direct Pitching
- Pour the yeast directly onto the wort’s surface, making sure the temperature is at or above the fermentation temperature.
- Gradually sprinkle the dry yeast into the wort, ensuring it covers the entire surface to avoid clumping.
- It’s best to add the yeast during the first part of the filling process. If you do this, you can hydrate the yeast at a higher temperature than the fermentation temperature. Then, fill the rest of the vessel with wort at a lower temperature to bring the overall temperature to the fermentation temperature.
Rehydration Instructions
- Sprinkle the yeast into a minimum of 10 times its weight of sterile water or boiled and hopped wort.
- Ensure the water or wort temperature is between 25°C to 29°C (77°F to 84°F).
- Let the mixture rest for 15 to 30 minutes.
- Gently stir the mixture to create a cream-like consistency.
- Pitch the resultant cream into the fermentation vessel.
