Lallemand WildBrew™ Philly Sour Yeast - 500g Bulk BrickWildBrew Philly Sour is a unique species of Lachancea selected from nature for its ability to produce both lactic acid and ethanol in a single fermentation step. This 500g bulk brick is the perfect solution for commercial breweries producing Gose, Berliner Weisse, and other tart ales without the need for kettle souring or bacterial inoculation. Philly Sour produces a clean, refreshingly tart profile with subtle notes of red stone fruit. Brewery Recipe
