Alcotec 48 is based around a “pure” yeast strain which is a temperature tolerant, high alcohol distillers strain. With the unique precisely composed nutrition, containing the nitrogen source, pH regulator, trace minerals, vitamins and an antifoaming agent, it is the perfect yeast compound for creating a high alcohol wash. It has a “dual” use, you can either use it for 20% (21% in special circumstances) alcohol in 5-6 days, or 14% in 48 hours (hence the name). The alcohol level is simply determined by the amount of sugar you add at start.
