Moonshine, white lightning, mountain dew, hooch, and Tennessee white whiskey are terms used to describe high-proof distilled spirits, generally produced illicitly. The word "moonshine" is believed to derive from the term "moonrakers" used for early English smugglers and the clandestine (i.e., by the light of the moon) nature of the operations of illegal Appalachian distillers who produced and distributed whskey.
