SafSour™ LB-1 is a high-purity Lactobacillus strain specifically selected for its ability to produce clean, sharp lactic acid. This 100g bulk brick is the ideal solution for commercial breweries producing Berliner Weisse, Gose, and other sour styles via kettle souring or co-fermentation. LB-1 is prized for its reliability and rapid acidification, allowing brewers to reach target pH levels (3.2 - 3.6) in as little as 24-48 hours. It provides a crisp tartness that is the perfect foundation for fruit-forward sour beers.
