This yeast is used to produce the “California Common” style beer. A unique lager strain, it has the ability to ferment up to 65F (18C) while retaining lager characteristics. Can also be fermented down to 50F (10℃) to produce marzens, pilsners and other style lagers.

Oktoberfest/Marzen Lager Yeast

This yeast produces a very malty, bock-like beer. It does not finish as dry as WLP830. It’s much slower in the first generation than WLP830, so we encourage using a larger starter during the first generation or scheduling a longer lagering time.

The excellent malt profile makes it well suited for bocks, doppelbocks, and Oktoberfest-style beers. A very versatile lager yeast, it is so well balanced that it has gained tremendous popularity for use in classic American-style pilsners. Also good for helles-style lager beers.
