Most likely antifreeze
Or using an old lead-soldered automobile radiator as a condensing coil.
And you can bet they're not keeping just the "middle cut" of each distillation run.
Wondering if it was run through a radiator. Gotta look at the bubbles when you turn the bottle up. Small bubbles good. Big bubbles bad. Or vice versa. Can’t keep it straight.
Reminds me that I need to take the last of my moonshine and share it with my father-in-law at his gravesite for Christmas.
Merry Christmas, Dad. Sure do miss you.
