Lager Yeast
Fermolager W
Attenuation: 82%
Best for: Pilsner, Helles, Bock, Vienna, Märzen
Fermolager W is a classic lager yeast for Pilsners and traditional styles, delivering clean fermentation, high attenuation, and a crisp, balanced finish.
Fermolager W is a German-origin bottom-fermenting yeast developed for a wide range of lager styles. It produces a clean profile with very low ester and phenolic character, ensuring clarity of both malt and hop expression.
Its high attenuation and strong flocculation support consistent fermentation performance and efficient processing. It is particularly well suited to Pilsner, Helles, Bock, Vienna, and Marzen styles where precision, balance, and repeatability are critical.
