Omega Yeast OYL-437 German Lager I + Liquid Yeast


Omega Yeast OYL-437 German Lager is propagated from one of the world’s most prominent lager strains. It sports a versatile malty profile with light esters at a wide fermentation range. Fermenting with this strain will help you maintain a more crisp profile by fermenting low or bring out slightly heightened esters at warmer temps (65 – 68°F). It avoids any hints of diacetyl and ups your lager game!
