Few people realize just how simple vodka is to make. It isn't aged or blended, it can be made from wheat, potatoes, turnips, corn, barley, rice, oats, etc. The distillation process is exactly like that of the simplest grain alcohol, except it is made from vegetables or grain. A good vodka is triple filtered through charcoal, which is simple and cheap. There is no art involved in the making of vodka, it is purely an industrial process. A little bit of the ingredient that was distilled is fermented into a wine and is added to the distilled alcohol to add as much or as little flavor as the manufacturer desires to the vodka.
So it is easy to see that outrageous prices being charge for those super premium vodkas are a total scam, and why so many people are trying to sell these super premium vodkas.
