The Yeast Bay PurePitch® Next Generation WLP4663 Berkeley Hills Sour Yeast Blend
PurePitch® Next Generation (an evolution of White Labs’ PurePitch®) delivers great shelf life, and provides a commercial pitch rate for homebrewers.
This blend of lactic acid producing Lachancea thermotolerans isolates is unique from any yeast we’ve ever isolated. In addition to creating an acidic character that is much more complex, multi-dimensional and reminiscent of a traditional long-aged sour as compared to a kettle sour, the attenuation, pH and ester profile are precisely tuneable based upon the percent of fermentables as glucose.
