When you start distilling spirits, you will first need to make a mash, or wash, is wine used for making spirit. Mash has a low alcohol content and is prepared by adding yeast, tap water and sugar and allowing it to stand for a few days. There are fermentation vessels with and without airlock. An airlock is not required for our turbo yeasts and a fermentation bucket with lid will be sufficient. See the instructions on the turbo yeast packaging for the correct ratios.
