The Alchemist can do 90-95% comfortably, all due to length of the columns. My three inch and four inch will do 94-95% abv in one run if the mash is done correctly. Please call if you want to understand this or having issues.
All these stills do everything from making essential oils, distilling chlorine fluoride and radiation, all heavy metals of out water, alcohol, medical alcohol, cooking alcohol,
slash fuel for your car= ethanol. There are hundreds of other uses as well. For micro distilleries you can make your Brandies, Rum and Whiskeys etc.
