Fermentis US-05 is a widely used and well-known American ale yeast strain. It is a ready-to-pitch, dry yeast that produces well-balanced beers with low diacetyl and a very clean, crisp palate. This yeast has the ability to form a firm foam head and present a very good ability to stay in suspension during fermentation.

• Recommended Fermentation Temperature: US-05 yeast performs optimally at a temperature range of 18-26°C, but it is commonly fermented at the lower end of this range for cleaner profiles.

• Attenuation: It has a medium to high attenuation, typically around 78-82%, which means it will consume a large proportion of the fermentable sugars, leading to a drier beer.

• Alcohol Tolerance: US-05 has an alcohol tolerance of approximately 9-11% ABV, making it suitable for a variety of beer styles, including higher gravity ones.

Suitable Beer Styles for Fermentis US-05:

1. American Pale Ale: US-05 is well-suited for American Pale Ales, providing clean and neutral flavors that allow the hops to shine.

2. American IPA: The clean fermentation profile and high attenuation make it a good choice for IPAs, highlighting hop bitterness, flavor, and aroma.

3. American Stout/Porter: It can be used in darker and roasty beers like stouts and porters, where it won’t overshadow the malt character.

4. American Amber Ale: This yeast is suitable for Amber Ales, complementing the balanced malt and hop profile.

5. Blonde Ale: For light and easy-drinking Blonde Ales, US-05 offers a clean and crisp finish.
