Working with high gravity brews or lower fermentation temperatures?

​Our online calculator at yeastman.com allows you to see the exact recommendation for you using your volume, temperature, and gravity. Allowing you to customize the pitch rate to anything you want, larger or smaller!


Increased Fermentation Speed

The demand for higher pitch rates has been steadily rising for decades. To fit brewer's needs we’ve optimized the cell count of PurePitch® Next Generation to ensure brewers worldwide see consistent, clean, and speedy fermentations. With our consistent pitch rates, brewers have seen shortened lag times resulting in quicker gravity drops.

Increased Viability

Improved shelf life – through process improvements and laboratory analysis, we monitor the glycogen content of the yeast cells to give them more energy when starting a fermentation.

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.

InnovationPowered by FlexCell Technology

Because we never stop, PurePitch® Next Generation has an improved proprietary film designed specifically for White Labs and allows for one-way off-gassing to promote yeast health and viability. 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.


Technology at your fingertips

A QR code on each package directs you to all the information you need to make the best beer: the quality report of every lot, additional strain-specific information, data, and recipes. ​White Labs is the industry leader in quality with the same quality and care taken for every culture, including proprietary qPCR methods (developed with Invisible Sentinel) for higher limits of detection. The online pitch rate calculator will recommend the right amount of yeast for a foolproof fermentation or allow you to customize the amount based on your desired pitching rate.
