WHAT IS 80, 190, 192, OR 200 PROOF ALCOHOL?

All ethyl alcohol products have a proof associated with the product description. The proof is a measure of the water content of the ethyl alcohol portion of the product, and any level of proof can be manufactured based upon the amount of water added. The proof is calculated as two times (2x) the actual ethanol concentration by volume. The most common pharmaceutical-grade alcohol products are 190, 192, and 200 proof. Vodka, on the other hand, is generally 80 proof.
