For over 25 years, White Labs has been committed to furthering the art of fermentation by making fresh, pure liquid yeast more accessible to the brewing, winemaking, distilling, cider making, kombucha and fermentation industries. Through research and development we continue to innovate in the areas of yeast and fermentation for professionals and enthusiasts alike.
Through our Research & Development team, White Labs has done extensive research on the differences between dry yeast and liquid yeast. Yeast contributes more than 500 flavor and aroma compounds and the use of lab-grown, high-quality liquid yeast creates a cleaner, more complex final product. All White Labs yeast comes with a guarantee that each culture has met our strict quality control standards.
PurePitch® is White Labs' state of the art packaging technology, with our patented FlexCell™ technology. White Labs yeast is propagated in all-malt wort, providing the perfect nutrients for growth and optimal performance. Our breathable FlexCell™ technology also reduces risk of contamination by growing and delivering yeast in the same package.
Yeast should be stored in the refrigerator prior to use. Remove the yeast from the refrigerator approximately two to six hours before pitching and allow the yeast to come up to room temperature. The reason for this is to prevent a temperature shock when the yeast is pitched.
PurePitch® contains 2.0-2.8 billions cells/ml.

Cultures are grown in small batches throughout a 17-day period to ensure the yeast is in optimal physiological condition for highest viability and multiple reuses. The cultures are propagated in all-grain wort produced in our custom brewhouses. Each culture undergoes a rigorous testing process from start to finish, which includes 61 quality checkpoints throughout the propagation cycle. Cultures are held following the completion of propagation to clear the final quality control process. Results shown reflect the product at the time of release. Samples in final packaging are retained at White Labs to assist with research and development. Our tests adhere to the guidelines of the American Society of Brewing Chemists, when applicable.

The shade of the yeast can vary between lots due to the wort used in the production of that specific lot as well as where the propagation vessel lies in the filling process. Some lots may be darker than others due to the protein or trub content, but the health and viability of the yeast are not affected. Every package of yeast that leaves our facilities falls within our acceptable SRM range, so you can rest assured that regardless of the color, your yeast is healthy and biting at the chance to ferment your wort.
