got my hands on White labs 672 (Brevis) 677 (Delbruekii) and split a batch (5 gallons each) - the one i have labeled as Delbruekii is cranking like no other blowing off for 2 days now. the other one is still. silent. nothing. Ive read conflicting things on these bacteria. Unless i mislabeled my carboys, Delbruekii is heterofermentive producing C02 etc. and Brevis is homofermentive producing only, or mostly, lactic acid. I will taste later this evening and PH test and report back.
