WLP925 White Labs High Pressure Lager Yeast Liquid Yeast is Used to ferment lager beer in one week. Ferment at room temperature; 62-68°F (17-20°C) under 1.0 bar (14.7 PSI) until final gravity is obtained, generally one week. Lager the beer at 35°F (2°C), 15 PSI, for 3-5 days to condition. Sulfur production is strong the first 2 days, then disappears by day 5.
HP Lager strain from White Labs is ideal for fermenting under pressure. When beer is fermented under pressure, it allows for the production of a clean flavor profile, even when fermenting a lager at room temperature. Fermenting under pressure is advantagous in that it reduces ester and fusel alcohol production, reduces or negates the possibility of oxidation, carbonates the beer during fermentation and allows you to ferment warmer than you would otherwise. Check out The Fermentasaurus if you are in the market for an affordable fermentor that holds pressure.
Do not need to carbonate, since at 1 bar entire time!
