White Labs WLP925 High Pressure Lager Yeast

Description

White Labs WLP925 High Pressure Lager yeast

A specialized lager yeast designed for pressure fermentation at room temperature. When fermented under 1.0 bar (14.7 PSI) pressure, this strain produces clean, crisp lagers with minimal ester and fusel alcohol production, even at warmer temperatures. Allows brewers to complete lager fermentation in one week at 62-68°F, eliminating the need for traditional cold fermentation while maintaining lager character. Produces strong sulfur initially that dissipates by day 5. Beer carbonates naturally during fermentation under pressure.
