I was hoping an actual person could offer me some advice. I work in a craft distillery and I'm getting a lot of mixed information on how compatible PVC is with high-proof alcohol. It definitely seems that "Food-Grade" doesn't necessarily mean "Alcohol-Grade". A. Is PVC hose safe to use for transferring Grain, Water, and most importantly, Ethanol? B. If not, is there a type of material you would recommend for any and all distillery applications?
