Fermentis SafAle US-05 American Ale Dry Yeast – 11.5g Sachet

Fermentis SafAle US-05 is a classic dry American ale strain for brewers who want a clean fermentation profile, dependable attenuation, and the kind of neutral yeast character that lets hop expression and malt balance stay front and center. It is a strong fit for pale ales, West Coast IPAs, amber ales, blonde ales, porters, and other recipes where the yeast should support the beer without crowding it.

This 11.5 g sachet is known for delivering a crisp finish with restrained ester production, medium flocculation, and solid all-around versatility. With a working range around 64 to 82°F and published attenuation around 78% to 82%, US-05 is one of the most useful dry strains to keep on hand when you want reliable performance across a wide range of modern American ale styles.

Practical Brewing Notes

SafAle US-05 is a good choice when you want consistent fermentation performance without building the recipe around expressive yeast esters. It works especially well in hop-forward beers, but it is equally useful in balanced malt-driven ales that benefit from a tidy, low-interference fermentation profile.

Because this is dry yeast, it is generally less risky to ship than liquid yeast. Even so, warm-weather exposure and extended transit are never ideal, so brewers should still avoid unnecessary heat and long delivery windows when possible.
