Chub, ya asked if anyone has used small Mason jars for our finished product? If you mean by "used" storing/aging and drinking from them, the answer is YES! I've used em myself, only prolem is the metal lids tend to rust if ya leave them full too long.
Thats probably due to water left in the product (surely a little corrosive 100proof alchohol wouldn't hurt em?
Matter of fact, my uncle used em by th case, course he had a slightly larger operation than any thing I would even dream of.
Ah yes, "ol Unc" died in prison after his third conviction fer moonshining wouldn't ya know?
He was 'bout 70 by then.
