Thumper
In Appalachian and Southern speech, a "thumper" (also "thump keg") is the secondary vessel attached to a moonshine still. Hot vapor from the copper pot "thumps" through it, distilling the liquor a second time and boosting proof.

Origin and Etymology
From Appalachian moonshining slang. "Thumper" describes the thump-thump sound as vapor hits liquid in the keg. The setup - copper pot plus thumper - dates back to Scotch-Irish distilling traditions brought to the mountains.
Usage Notes
Still widely used by legal distilleries and hobbyists seeking authentic mountain methods. Outsiders may call it a "doubler" or "secondary condenser," but "thumper" remains the colorful local term.
