White Labs is the industry leader in quality with 38 quality checkpoints for every single strain. The same quality and care you trust, since 1995.


With 79 Core strains and countless more in the Vault, White Labs has a strain for every beer whether you’re using a trusty workhorse like WLP001 California Ale Yeast or experimenting with something new and rare in the Vault. 


Our teams are passionate about what we do – a combination of Departments from Sales & Marketing, Customer Service, Microbiology, Production, Packaging, White Labs Brewing Co, White Labs Analytical Laboratory, Education, and R&D are dedicated to making the best yeast possible.  This drives our mission to help our customers make the best beer, wine, and spirits in the world, from 5 gallons to 500 barrels, every time.
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® Next Generation, an evolution of White Labs’ PurePitch® – the most superior and consistent yeast on the market – has been made even better with new packaging powered by FlexCell® Technology for ease of use and a pitch rate resulting in a foolproof fermentation every time.

PurePitch® Next Generation combines the ease of a bottle and the innovation of PurePitch®, offering a modular pouch with a cap and a consistent cell concentration intended to pitch at 7.5 million cells/ mL; a commercially recommended pitching rate to ensure a foolproof fermentation.

Working with high gravity brews or lower fermentation temperatures?

​Our online calculator at 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!

Our yeast package sizes include:
  • PurePitch® Next Generation = 1.75L
  • PurePitch® Classic/Organic (Only Available through WL Copenhagen) = 2L
  • PurePitch® Nano = 500mL
  • PurePitch® Homebrew  = 35-50mL
  • PurePitch® Custom Pour
Along with the package itself, we have updated our online pitch rate calculator at to help customers dial in their pitch rate and package needs with a well-defined recommendation for the number of pouches needed, based on beer style, batch size, temperature and gravity to ensure the ideal pitch rate.

PurePitch® Next Generation is made to contain 2.15 billion cells/mL in every package.
PurePitch® Next Generation is currently available in an optimized and convenient 1.75L size. A modular design to result in one pouch is a pitch 5 HL of standard beer at a rate of 7.5 million cells/mL. Providing flexibility for customers to achieve a customizable and more effective pitch rate for any batch size and fermentation condition.No matter the strain, PPNG provides consistent cell counts for consistent fermentations.

PurePitch® Classic/Organic (Only Available through WL Copenhagen) is made to contain 1.8 to 2.8 billion cells/mL in every 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.

To ensure the yeast is in optimal physiological condition for the best flavor production, highest viability, and multiple reuses, White Labs yeast utilizes a 21-day growth and testing program.

Our yeast cultures are lot controlled, go thru 38 points of verified quality checks, and end with our complete QC toolkit of every lot after final packaging.

Certificate of Analysis with detailed data, including cell count, yeast viability, and microbiological verification, are available for every lot and package size, imbedded in a QR code on the package and stored on
We always encourage customers to do their own testing as well, as should be done on all ingredients and batches, but we want to give customers the confidence of knowing the quality control we perform at White Labs. 

Quality Parameters
  • Adhering to industry-standard American Society of Brewing Chemist (ASBC) methods, White Labs’ monitors our yeast ranging from parameters of

    • Culture Purity

    • pH

    • Attenuation

    • Microbiological Contaminants

    • Accurate and Precise Cell Counts


Testing for the STA1 (Diastatic) gene in our strains

All of our strains have been identified as either STA1+ or STA1- strains via PCR techniques. All strains are tested on LCSM wild yeast media which can easily detect STA1+ contamination. Additionally, molecular techniques, such as qPCR, are being used to detect STA1+ yeast in our cultures.

There are many ways to make yeast. With more than 25 years of scientific exploration and technological innovation in fermentation under our belt, we know our controlled process results in the highest quality yeast with optimum cell mass and physiology.
While you can create high levels of cell mass in a fast propagation, superior yeast physiology is only achieved through a slow and controlled growth process. 

Our 21-day growth process along with our 38 points of verified quality checks provides optimum cell physiology and performance, such as high glycogen content, which is critical for flavor, fermentation, and long-term yeast health, especially for customers reusing yeast for multiple generations.

The Aseptic Transfer System was designed in conjunction with PurePitch® Next Generation and offers brewers a new and affordable way to pitch first-generation yeast inline.  Together, the Aseptic Transfer System and PurePitch® Next Generation provide a safer, cleaner, and more efficient way to pitch.

In order to maintain viability and vitality of our yeast cultures, stored yeast must remain cold in order to limit metabolic activity.
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.

Shipping is calculated based on a percentage of the order total or if the order is small, there is a minimum shipping charge that can vary depending on the carrier of choice.

There is no difference in charge based on where the product is shipping from.

***If you are within Ground radius from either San Diego or Asheville, this would be the cheapest option shipping-wise. You can make this choice in order via Yeastman.
***Otherwise, we recommend 2-day for retailers and overnight for professional breweries.
Unfortunately, shipping delays can occur based on weather, mechanical issues, or an increase in the number of packages going through a particular hub.

If delivery of your order is delayed for some reason, please make sure that the parcel is inspected once it finally arrives at the destination address.

We can replace or credit any item that is damaged in shipping as long as we are notified and emailed to [email protected] within 30 days of the order shipping.

*Most of the time a 1 or 2-day delay will not be harmful to the viability of the yeast, thanks to our insulated packaging!
