A strain of Lactobacillus brevis. It is extremely hop sensitive and therefore should only be used in worts without hops. Lacto brevis is a great strain for souring wort in the kettle or fermenter, prior to adding yeast for fermentation. For best performance use inoculation rates of 0.1% - 1.0% by volume of wort. Lacto brevis will typically drop wort pH to 3.3 in 1-4 days depending on temperature and inoculation rate.
