Craft vodka is all the rage at the moment, so you'll find some inexpensive as well as some uniquely made vodka. Traditionally and by law, vodka can be made from anything that you can extract sugar from, barley, wheat, potato, even milk!! Vodka must be distilled to between 95%-96% abv, and water is subsequently added to achieve a more marketable abv. How much flavour remains depends on the distiller, but usually charcoal filtration is used to strip away any colours or flavours.
