 Improved Performance

Our goal in creating PurePitch® Next Generation for Homebrewers was to provide a product that will allow hobbyists and small scale brewers a convenient and modular package to pitch a consistent 7.5 million cells/mL; a commercially recommended pitching rate for standard ale ranges. The same package has proven to be an optimization to PurePitch® for larger professional brewers for over a year.

Now at 2x the pitch

Now with more yeast, get a foolproof fermentation without a starter. Following a commercially recommended pitching rate allowing you to pitch like the pros!

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.

PurePitch® Next Generation for Homebrewers FAQ

Is PurePitch® Next Generation larger than your previous package?

Yes!  Now with more yeast, you get double the pitch. PurePitch® Next Generation is designed to pitch at a rate of 7.5 million cells/mL per 5 gallons/19 liters, a commercially recommended pitching rate for standard ale ranges. 

Do I need to make a starter?

No! For any standard ale, you will get the perfect fermentation by pitching directly - NO STARTER NEEDED.  

What if I am brewing something that is not a “standard ale” - how do I know how much yeast I need for my batch?

Each pouch of PurePitch® Next Generation provides general quantity recommendations per 5gal/20L of wort.

​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!

What does 7.5 million cells/mL mean?

When pitching 1 pouch of PurePitch® Next Generation into 5 gal/19L of wort, there will be 7.5 million cells per milliliter.  This is a commercially recommended pitching rate, allowing you to pitch like the pros. 

What is the shelf-life of PurePitch® Next Generation?

The shelf-life is 6 months from the QC-release date labeled on the package.  As a result of the proprietary dual-layer film, yeast are able to remain in excellent condition with high viability and performance.   

Why change to a new version of PurePitch® ?

Our number one request from the homebrewing community has been for more yeast! Next Generation has been developed in response to brewing styles and fermentation techniques requiring more yeast than ever before, as well as the desire for a more optimal yeast package without the need for a starter.
