WLP925 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 advantageous 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.

Use to ferment lager beer in one week! Ferment at room temperature (62-68°F) under 1.0 bar (14.7 PSI) until final gravity is obtained, generally in one week. Lager the beer at 35°F, 15 PSI, for 3-5 days, to condition. Sulfur production is strong first 2 days, then disappears by day 5. Do not need to carbonate, since at 1 bar entire time.

PurePitch® Next Generation—now with more yeast, get a foolproof fermentation without a starter! Just twist the cap & pitch!

Why PurePitch Next Gen versus other options?
Typically yeast manufacturers use a range for how many yeast cells are going into each package. This can vary widely, especially from strain to strain. Next Gen offers a far more precise cell count across all strains allowing you to use the Whitelabs exclusive pitch calculator. Simply scan the barcode on the back of each package to be taken to their online calculator. Enter the volume, strength, and pitching temperature of the wort you are fermenting and the calculator tells you exactly how much yeast to pitch. You will be fermenting like a professional brewer, using the same concentration of yeast every time and enjoying more consistent results. Don't need a full package? Put the lid back on and store in the refrigerator for your next batch. Whitelabs has also increased the viability (the number of living cells in the package) over the shelf life of the yeast. Next Gen strains are grown in their unique, small-batch reactors to assure freshness and then packaged in a special film that allows for off-gassing, assuring that their viability is absolutely industry leading.

For best results we always recommend ordering an ice pack with your liquid yeast.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.
