Fermentis Safale US-05 American Ale Yeast


American ale yeast producing well balanced beers with low diacetyl and a very clean, crisp end palate. Forms a firm foam head and presents a very good ability to stay in suspension during fermentation. Clean ferment characteristics with a reliable result. US-05 is the most popular beer yeast in the world.

Ingredients: Yeast (Saccharomyces cerevisiae), emulsifier E491


Alcohol tolerance (ABV): 9-11%
Apparent attenuation: 78-82%
Sedimentation: Medium
Total esters: Low
Fermentation Temperature: 18°C - 28°C
Dosage: 0.5 - 0.8 g/L for standard ferments. 


Direct Pitching - Pitch the yeast directly in the fermentation vessel on the surface of the wort at or above the fermentation temperature. Progressively sprinkle the dry yeast into the wort ensuring the yeast covers all the surface of wort available to avoid clumps. Ideally, the yeast will be added during the first part of the filling of the vessel; in which case hydration can be done at wort temperature higher than fermentation temperature, the fermenter being then filled with wort at lower temperature to bring the entire wort temperature at fermentation temperature.

Rehydration - Alternatively, sprinkle the yeast in minimum 10 times its weight of sterile water or boiled and hopped wort at 25 to 29°C (77°F to 84°F). Leave to rest 15 to 30 minutes, gently stir and pitch the resultant cream into the fermentation vessel.
