ALL YOU NEED TO KNOW ABOUT YEAST
TO PROFESSIONALS & ENTHUSIASTS
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.
All of our people are passionate about what we do – a combination of Departments from Sales & Marketing, Customer Success, 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 every time.
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.
PurePitch® Next Generation gives customers a consistent cell count to more accurately pitch for a foolproof fermentation. We’ve also made it easier to customize pitch rates using the online pitch rate calculator at www.yeastman.com. Get recommendations for the number of pouches needed based on beer style, batch size, temperature and gravity to ensure the ideal pitch rate.

For specific information on lots, you can look up the QC sheet: Click Here
For Pro sizes, pitching 1 pouch per 5HL
For Homebrew sizes, pitching 1 pouch per 5 Gal/20L
There will be 7.5 million cells per milliliter, a commercially recommended pitching rate for standard ale ranges.
We’ve also made it easier for customers to manage pitch rates by updating our online pitch rate calculator at www.yeastman.com to give customers 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.

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

Top 5 Benefits of White Labs Liquid Yeast
-
Selection. The expansive variety of strains with Core and specialty cultures allows you to craft any beer style, NA beer, and non-beer beverages.
-
High Viability & Vitality. Because of our 21-day process, we make yeast resulting in big plump cells full of nutrients and healthy cell membranes great for sustained viability and reuse.
-
Flavor. Distinct aromas and complex flavors due to the health and viability
-
Flocculation. Predictable flocculation patterns, even after multiple reuses. This results from robust cell membranes with intact flocculation proteins, leading to efficient flocculation.
-
Modular Sizes Resulting in Optimal Pitching Rate. Precise and standardized cell counts based on scientific data for a foolproof fermentation every time. Modular packages allow customizable calculations for pitch rates to meet your every need.
Always store the yeast at temperatures between 36°F to 40°F (2°C–4°C) and follow the recommended best by dates for optimal performance, 5-7 months from QC clear. Keep yeast in the refrigerator until needed. Remove yeast at least two hours before pitching, so the slurry can come close to room temperature. To inoculate, sanitize, twist cap, and pitch. An opened pouch, if refrigerated, can be used until its best by date. DO NOT FREEZE
Top 5 Benefits of White Labs Dry Yeast
-
High Live Cell Count. Over 3 billion live cells per gram, along with extra nutrition and sterols from cell membrane content of non-viable cells.
-
Convenience of Production Planning. Extensive shelf life (12-24 months from production date) makes scheduling, planning, and those unforeseen issues stress-free.
-
Available Anywhere You Brew. White Labs Yeast will now be available for global brewers who had challenges importing liquid yeast, with straightforward and more affordable delivery in dry format.
-
Easy to Use. Straightforward pitch rates and no rehydration is necessary for a hassle-free fermentation.
-
Gluten-Free. Propagated on beet molasses and is 100% gluten-free.
All dry yeast should be stored refrigerated to maintain 36°F to 40°F (2°C-4°C) the appropriate shelf life. Dry yeast can be used up to the expiration date printed on the package, 2 years from production date. Once a pack is opened, use the yeast as quickly as possible. An opened pack must be stored refrigerated and used within one week. A re-sealed vacuumed and refrigerated pack can be kept until the end of its shelf life. DO NOT FREEZE

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.
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.
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!
How to recycle:
- Caps can be removed and recycled curbside
- Recycle pouch at your local retail store with #4 plastics collection programs
To inquire about restock dates for homebrew and to place a backorder, please email, chat, or call 1-888-593-2785. From that point, we can set up a backorder of the out-of-stock items, or you can place them on your next homebrew order, whichever is preferred.
Nano Bundle (5 x 70mL pouches) and Nano Pouch (1 x 350mL) have the same volume of yeast and the same price. We may substitute your preference based on availability and ship date.
