OBTAINIUM Light Whiskey came into existence in 1968 because consumers were moving away from Bourbon and more into clear spirits such as vodka or gin. Light whiskey is distilled between160-190 proof. Contrast that with Bourbon or American Rye which tops out at 160 proof. It must be aged in used, charred oak barrels or new, uncharred oak. Most distilleries didn’t let it age very long. Sourced from MGP in Indiana. Light whiskey fell out of favor, and stocks were left hanging around, mostly ignored and forgotten.
