White Labs NEW PurePitch has improved shelf life through process improvements and laboratory analysis, White Labs monitor the glycogen content of the yeast cells to give them more energy when starting a fermentation.

Each PurePitch package pitches a consistent 7.5 million cells/mL.

PurePitch Next Generation features a breathable proprietary dual-layer film designed to allow for more effective off-gassing to reduce product inflation and deliver higher viability and shelf life for the yeast. While the industry standard shelf life is 2-4 weeks, PurePitch Next Generation achieves an impressive five to seven-month shelf life. The cap allows for ease of use, no more scissors or fumbling with two-layer film, and the option to open and reseal for sampling or using partial pouches.
