Mangrove Jacks M84 Bohemian Lager Yeast - Craft Series Yeast. Bohemian Lager Yeast is characterized by its dry and clean palate, typical of traditional Czech brewing. Lagering periods as short as 4 weeks may produce acceptable beer, but allowing beer to lager 6-8 weeks will result in beer that is richer, smoother, with a more refined aroma and flavour.
