WildBrew™ Philly Sour is a unique species of Lachancea selected from nature by University of the Sciences in Philadelphia, PA, USA (Patent pending N° PCT/US20 18/043 148). WildBrew™ Philly Sour produces moderate amounts of lactic acid in addition to ethanol in one simple fermentation step. This first yeast in the WildBrew™ series is a great choice for innovative, sessionable sour beers with refreshing acidity and notes of stone fruit. With high attenuation, high flocculation and good head retention, WildBrew™ Philly Sour is an ideal yeast for traditional styles such as Berliner Weiss, Gose, American Lambic Styles and American Wild Ales, and its resistance to hops make it perfect for Sour IPA’s. Usage: The pitch rate will affect the fermentation performance and flavor of the beer. For WildBrew™ Philly Sour yeast, a pitch rate of 50-100 g per hL of wort is sufficient to achieve a minimum of 0.5 - 1 million viable cells/mL. More stressful fermentations such as high gravity, high adjunct or high acidity may require higher pitch rates and additional nutrients to ensure a healthy fermentation. WildBrew™ Philly Sour is a slow fermenting, killer negative strain and will tend to be outcompeted by other brewing strains. For this reason, it is not recommended to re-pitch this strain. WildBrew™ Philly Sour is not recommended for bottle conditioning applications. A dedicated bottle conditioning strain such as LalBrew® CBC-1 should be used when bottle conditioning WildBrew™ Philly Sour fermentations. As a non-Saccharomyces species, WildBrew™ Philly Sour should be treated according to normal best practices for handling wild yeast.
