A blend of two Lactobacillus species, L. brevis and L. plantarum. This blend is designed to be usable at a wide range of temperatures, and is especially suited for kettle souring/sour worting. Escarpment Labs recommends pre-acidifying wort to 4.5 with lactic acid, then pitching the Lactobacillus blend in a CO2-purged kettle or fermentor at 32-42ºC.
