Fermentis

Fermentis is a leading producer of active dry brewing yeast, offering dependable fermentation solutions for home brewers, craft breweries, and professional beverage producers around the world. Fermentis is part of Lesaffre, a company whose fermentation and yeast expertise stretches back more than a century; the roots of its historic site in northern France date to 1853, with yeast eventually becoming a central focus of the Lesaffre business. For brewers, Fermentis is best known for its SafAle™, SafLager™, and SafBrew™ families of dry beer yeast. The selection covers everything from clean American ales and traditional English beers to crisp lagers, expressive Belgian styles, wheat beers, and specialty fermentations.

What makes Fermentis yeast especially practical is the combination of strain diversity with the convenience and stability of active dry yeast. Many strains can be pitched directly into wort, simplifying yeast handling while providing brewers with predictable fermentation performance. Popular strains offer distinctly different brewing tools: SafAle US-05™ provides a clean, neutral profile suited to American and hop forward ales, while strains such as SafAle BE-134™ emphasize fruity, spicy Belgian character and high attenuation, and the SafLager range provides options for different lager profiles. This variety makes Fermentis a useful brand for beginners looking for straightforward, reliable dry yeast as well as experienced brewers selecting strains according to attenuation, sedimentation, fermentation temperature, ester production, and desired flavor profile.
