Our Yeast

Making the best liquid yeast, services and education accessible to professionals and enthusiasts

What began as homebrewers searching for higher quality yeast quickly grew into a team of dedicated biochemists exploring new ways to advance brewing altogether. Today, White Labs stands at the intersection of science, education and craft. Constantly striving for perfection, and in the process continually raising the bar in the art of fermentation.

Every day, we set out on a single mission: to stretch the limits of science in order to set new standards in purity and freshness. From the industry’s first pitchable liquid yeast, to a complete revolution in the way it’s propagated and packaged, our innovative spirit is tireless. Our belief is that creating the best products goes hand-in-hand with making the best use of them. This has inspired a culture of education and collaboration with brewers, distillers and winemakers the world over.
 

PurePitch®

The process for cultivating pure yeast cultures had not changed much since Emil Christian Hansen isolated the first brewers yeast and developed a process for propagation in the late 1880s. Soon after White Labs began producing liquid yeast, we embarked on a journey to revolutionize the art of fermentation. We believed there was a better way to propagate yeast that could reduce our company’s environmental footprint while creating a streamlined process that would provide a better quality culture.
 
Rather than the traditional method of transferring the finished yeast to a number of vessels and ultimately into our commercial packaging, with the FlexCell™ process we use a flexible container to propagate the yeast and package it in this same material.

Our team developed the FlexCell™ process which uses proprietary patented technology to cultivate the yeast. Rather than the traditional method of transferring the finished yeast to a number of vessels and ultimately into our commercial packaging, with the FlexCell™ process we use a flexible container to propagate the yeast and package it in this same material. This process reduces the risk of contamination and creates yeast that has had limited exposure to the environment. In addition to creating the industry’s first pitchable yeast grown and delivered in the same package, White Labs is demonstrating our commitment to sustainability by reducing water, electricity and cleaners used to sanitize traditional propagation vessels during the transfer process and reducing our overall use of rigid plastic packaging material. The PurePitch® package is more recyclable and more breathable reducing the chance of gas buildup and maintaining a favorable environment for the yeast. The FlexCell™ process and PurePitch® package delivers the purity and high-quality yeast that you expect from White Labs.

Why Liquid Yeast?

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.
 

                    Liquid Yeast

               Highest possible purity
               Enhanced esters

               Higher viability after fermentation
               Multiple generational use
               Higher flocculation
 

                    Dry Yeast

                              Higher fusel alcohols and acetaldehyde
   Phenolic characteristics possible 
   Lower viability and flocculation 
   Muted flavor and aromas
   Decrease in purity
 

Research & Development, The Forefront of White Labs

Our Research & Development team executes scientific research and applies the latest developments in our field, to identify areas of technological advancement within our manufacturing operations, including new strain development, improved culture health and stability, and novel propagation technologies.  Through our commitment to discovery and learning, White Labs is able to share these valuable innovations with the beverage industry as a whole.
