White Labs WLP661 Pediococcus Damnosus is a cocci bacteria known for its souring capabilities by producing lactic acid. High diacetyl producing and slow growing, it is perfect to add to any sour program.
White Labs yeast is world-renowned for quality and innovation, certified kosher, GMO free, and subject to thorough quality analysis before being packaged. Beverage Factory is closer to White Labs than any other online reseller, allowing us to provide the freshest yeast possible with the highest vitality.
Due to variable temperatures and transit times we are unable to guarantee that the yeast will remain at the ideal temperature for the entire journey. For increased protection, we suggest adding ice packs and insulated packaging, available below as optional upgrades. If you are ordering yeast during summertime or are located in a warmer climate, we recommend ordering dry yeast rather than liquid yeast.
