Alcotec Rum Turbo Yeast contains both the yeast strain to best promote the fine flavours from your raw materials and the enzyme needed. For grain or molasses based recipes, we have added a GA (glucoamylase) enzyme which breaks down dextrins which are leftovers from the raw materials after fermentation. For grain based recipes, you also need to pre-treat the wash with Alcotec Alpha Amylase Enzyme. Available in 73g sachets (108g for Australia/NZ)
