| [[Mainiacal Yeast]] (CLOSED) || MYLP2 || ''L. plantarum'' || Facultatively heterofermentative || || Isolated from grains going through the steeping process at Blue ox Malthouse. It produces a clean lactic sour and is a viable option for kettle souring, co-pitching, or post fermentation. Recommended fermentation temperature is 70-105°F <ref name="Amaral_Mainiacal" />.

| [[Mainiacal Yeast]] (CLOSED) || MYLD1 || ''L. delbruekii'' || Homofermentative || || Isolated from a spontaneous beer, this strain likes it warm but not to hot. It does not sour as quickly and will require some longer aging times to reach terminal pH. It produces a clean acidity with a hint of farmhouse like straw. Recommended fermentation temperature is 65-90°F <ref name="Amaral_Mainiacal" />. '''Commercial pitches only'''.
|-
| [[Mainiacal Yeast]] (CLOSED) || MYLB2 || ''L. brevis'' || Heterofermentative || || Produces a clean lactic acidity, but generally doesn't produce as much lactic acid as some other variants. It's best used co-pitched with other microbes and allowed to age. Expect this strain to be a bit lighter on the souring side leaving a tart refreshing beer. Recommended fermentation temperature is 60-85°F <ref name="Amaral_Mainiacal" />. '''Commercial pitches only'''.
