Fermentis · Safale American Ale US-05

The Fermentis Safale American Ale (US-05) is a dry, ale type yeast known for its versatility and reliable performance. With an attenuation rate of 81.0%, it demonstrates a high capacity to ferment available sugars, resulting in a drier beer. The yeast exhibits a medium flocculation, meaning it forms moderate clumps and settles in the middle of the spectrum between high (clear beer) and low (cloudy beer). It has a low alcohol tolerance, making it ideal for brewing standard strength beers rather than high alcohol variants.

The Safale US-05 thrives at fermentation temperatures between 53.6-77.0 °F (12.0-25.0 °C), accommodating a wide range of brewing environments. Typical beer styles brewed with this yeast include American Ales, Pale Ales, IPAs, Porters, and Stouts, but its neutral flavor profile allows for diverse application across many styles. This yeast is appreciated for its clean, well-balanced and bright flavor profile, promoting the malt and hop character of the beer without introducing significant yeast-derived flavors. It is an excellent choice for brewers aiming for a true-to-style American craft beer character.
