This revolutionary type of pot still is air-cooled and doest use water at all, which is great news for drought affected or water restricted regions. Wh's more, it's compact and as easy to use as your kitchen kettle. Most other air stills are made largely to distil water and often work too hot or too fast to produce good quality spirit, but the Turbo Air Still is designed to work at the correct temperature and optimum rate for alcohol distillation. It's fast too, distilling 4 litres of wash to make 1 litre of spirit in just two hours. It's also made from high quality stainless steel. It produces distillate at about 55% abv. As this still is a pot still and the alcohol is not 'purified'; in a reflux column it is important to produce the wash from ingredients that will produce the highest quality wash.
