Lallemand is a global leader in the development and production of yeast, bacteria and nutrients. Synonymous with quality, Lallemand produces some of our very favorite products. MoreBeer! has had a long working relationship with Lallemand as we package down Go Ferm, Fermaid K, Fermaid O, and several strains of wine yeast. Recently Lallemand has put considerable energy into releasing super interesting dry yeast strains in both sachets and bricks.
