Over a decade ago, we sought to produce a dry White Labs strain to support the growing interest in dry brewing yeasts. During that quest, we found that there wasn’t a good opportunity to make the dry yeast we wanted to make, one we could 100% stand behind.
After several years of research and trials with dry yeast production and fermentation, we finally entrusted our beloved yeasts to a family-owned and operated, experienced yeast manufacturer, with a passion for the industry, just like us: Lallemand Brewing. In collaboration, we brought the yeast strains and uncompromising quality White Labs is known for in a brand new product. This first strain release brings you an authentic dry version of WLP001 California Ale Yeast®, the most popular brewing strain in the world.
The standardized quality control we perform on our liquid yeast is also the same as what we employ with our dry yeast. The process by which liquid and dry yeast are grown, stored, and used can be different, resulting in some practical differences for brewers and nuances in the flavor and aroma profile of the final product.
Now you may ask, “Are your dry and liquid yeast the same?” Yes, and no. This strain is indeed WLP001 California Ale Yeast® and can be verified by genetic identification.
Providing the most flexible options for brewers has always been important to us, and we’re excited to offer another choice when it comes to 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
How does White Labs WLP001 California Ale Yeast® compare to other similar strains?
Most dry yeasts are produced in a conventional process with propagation, drying and quality control, including WLP001 California Ale Yeast® and you will get the same quality, viability and performance you would expect from an active dry yeast.
WLP001 California Ale Yeast is genetically distinct from other strains of similar origin, making this the only California Ale Yeast out there.
Our dry yeast is also tested using proprietary qPCR methods, allowing for higher sensitivity for potential wild yeast contaminants. Using WLP001 California Ale Yeast®, you will get the craft industry’s most popular strain, known for its clean and robust fermentations, along with the confidence of the uncompromising White Labs quality control standards.
What is the cell count?
The viable cell count is generally 5-10 x 109 cells per gram and a minimum of 5 x 109 cells per gram.
What is the viability?
Dry yeast viability is generally expressed in the number of viable cells per gram rather than as a percentage, like liquid yeast. White Labs Dry Yeast typically contains 60-80% viable yeast with a minimum of 5 x 109 viable cells per gram. The remaining dead yeast provides nutritional value in fermentation, including sterols, nitrogen, and vitamins.
What are the sizes you offer in dry?
White Labs Dry Yeast are available in Professional (500g) and Homebrew (11g) sizes.
How much yeast do I need?
We recommend 0.5-1g of dry yeast per Liter of wort up to 18° Plato.
500g → 5-10hL
11g → 20L/5 gallons
To get specific pitch rate recommendations, see our yeastman.com pitching rate calculator and select Dry Yeast.
How should I store it?
While dry yeast can be stored at room temperature for short periods of time, we recommend storing all dry yeast refrigerated (36º-40ºF/2º-4ºC) to maintain the appropriate shelf life.
Is it gluten-free?
Yes, the yeast is grown on molasses, so it is gluten-free.
Is it organic?
No, it is not.
Why is the color different from lot to lot?
There are color variations, but they have no impact on the yeast's performance or the beer's flavor. These variances are mainly caused by variations of raw materials (molasses) and, to a lesser extent, pH towards the end of propagation.
Note to readers: This is not about beer and health but more about the history and future of beer and how keeping the sugars in balance has advantages for many people. Creating a lighter beer with great flavor also has market advantages as the popularity of these styles continues to climb. Health and beer in…
