White Labs

White Labs Inc. Pure Yeast and Fermentation team members have been active in the American and worldwide craft brewing movements since the 1980s. The company, which has grown to include offices in California and Colorado, provides a wealth of services to not only brewers but also winemakers, distillers and others in the fermentation business. These pure liquid yeast cultures are designed to pitch directly to 5 gallons of wort if they are fresh. Yeast starters may be required for yeasts that are more than a few weeks old. All liquid yeasts need to be kept in the fridge until used.
