I finally received a response from a non salesperson at Mangrove Jacks the other day, according to them M-84 Bohemian is a bottom fermenting S. Cerevisiae, M-76 Bavarian is a bottom fermenting combination of S. Cerevisiae and S. Pastorianus, and M-54 Cali Lager is a combination of bottom and top fermenting S. Cerevisiae. I guess in today’s world one can call a thing whatever the hell one wants.
