Reflux-still.jpg

A Reflux still is effective in producing an odourless and flavourless end-product. Thus, for individuals intending to produce potent neutral-taste alcohol, reflux-based stills are the best. This still works by condensing the material coming up as vapour during the purification process, and which is again re-distilled by the vapour below. Afterward, the water is separated from the alcohol at the stage, and falls to the boiler in liquid form, whereas the liquor arises as condensed vapour. When the cool liquid mingles with the hot vapour, the end-product is pure distillate.
