A Versatile Blend for Perfectly Balanced Sour Beers

White Labs Lactobacillus Blend (WLP4682) is a dynamic combination of two Lactobacillus species—L. plantarum and L. brevis—designed for creating clean, balanced, and consistent sour beers. Ideal for kettle souring, Berliner Weisse, Gose, and other sour styles, this blend produces pleasant tartness without overpowering acidity. Brewers seeking to craft flavorful and approachable sour beers will find WLP4682 a perfect addition to their fermentation toolkit.

Our Commitment to Yeast Health

At SoCal Brewing Supply, we take yeast storage and viability very seriously. We ensure yeast is always stored under optimal conditions, with 24-hour monitoring of refrigerator temperatures to prevent spikes that could negatively impact yeast health.

For liquid yeast orders, we recommend shipping with an ice pack and insulated envelope to ensure your yeast arrives in top condition. It’s normal for ice packs to melt during transit; their purpose is to protect the yeast from extreme temperatures caused by external weather conditions.
