Goodness gracious, you are dramatic. Nothing wrong with using beer fermenters for distilleries; I am familiar with folks who do. a tank is a tank is a tank...use a fiberglass tank, use a 55 gallon steel drum, use a hdpe tank, use a glass tank, I know distilleries who are using each one (yeah, even the glass one). I know nothing of whiskey washes, but I don't see how ngs and rum would be incompatible.
In fact, equipment from a microbrewery is ideal because it will have temperature controls already on it, in case you need to control the fermentation temperature. Plus if it's a good deal, you could use those stainless tanks as holding tanks. If anyone here has some used, good condition tanks from a microbrewery at a great price, contact me. You probably don't want to contact ckrogstad
I wonder how much they'll get for the piano
