Some posts in another thread told me there are some vodka drinkers here. I would like to invite vodka drinkers (okay, anybody) to react/respond to the following:
Vodka is grain neutral spirits (GNS) and water. The water is added to reduce the 190+ proof GNS to between 100 and 80 proof for bottling. That is the legal definition of vodka. Vodka, by law, has no "distinctive character, aroma, taste, or color." The only reason two different vodkas taste different is because different sources were used for the water used to dilute it after distillation. Therefore, the only difference between the contents of a $10 bottle of vodka and a $50 bottle of vodka is that different water has been used to dilute the GNS.
