White Labs PurePitch® Liquid Lager Yeast Strains
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.
