| [[Wyeast]] || 5335 || L. buchneri || 1L starter, 1.020 DME sterile wort, no stir plate, no O2, starter at 90°F if possible 5-7 days || Incubate at 90°F for 5-7 days for greater lactic acid production.

| [[Wyeast]] || 5223-PC || L. brevis || no stir plate, room temp is fine || Heterofermentative (produces lactic acid, ethanol and CO2), more hop tolerant. Does well at room temperature. AVAILABLE ONLY FROM JULY THROUGH SEPTEMBER 2014 (Michael Dawson from Wyeast indicated that this culture may return at some point). Jamie Daly indicated on MTF that he got almost no sourness after 24 hours at 100°F (37.8°C). He lowered the temperature to 90°F-95°F (32.2°C-35°C) for 36 hours, and the pH of the wort went down to 3.29. Thus, Jamie recommends 90°F-95°F (32.2°C-35°C) for 60 hours for better souring; avoid warmer temperatures. He also aerated his starter of L. (brevis 2L starter of 1.020 dme) and set it on a stir plate at 95°F. The beer wort was not aerated, and the fermenter was flushed with CO2. These methods need verification.
