This super fast fermenting, high alcohol yeast from Alcotec can ferment 6kgs of sugar in 25 litres of water to produce 14% alcohol in 24 hrs. In order to obtain the best results, it is usual to add activated charcoal to the wash at the beginning of fermentation and then add Turbo Klar after degassing the wash to remove any dissolved CO2. In countries where home distillation is legally allowed, this "base spirit" can be further distilled in a home distillation unit to produce standard 40% spirit. In the UK, the undistilled base spirit is mixed with any of the available "essences" to produce your favourite spirit or liqueur.
