moonshine mash pronunciation
/MOON-shine mash/
Meaning
Mash is the wet, working batch that turns corn (and sometimes sugar or other grain) into a sour beer you later run through a still. In the mountains that batch was the whole job before the run: sprouted corn ground up, scalded into mush, left to bubble until it went sour. Folks talk about mash like cook talk about dough. If the mash is off, the liquor will be too.
How folks use it
- “He's out tending the moonshine mash like it was a garden.”
- “That mash smells sharp enough to curl the paint in the shed.”
Origin and etymology
Mash is old brewing and distilling English for grain mixed with water. Appalachian moonshiners kept the word for the corn beer that sits before a run. Writers like Horace Kephart described mountain "sweet mash" turning into "sour mash" once it fermented. The phrase moonshine mash just names that batch in liquor talk.
Frequently asked questions
Is moonshine mash the finished liquor?
No. Mash is the fermented grain mix. The liquor comes later, after you run it through a still.
