RE: [Distillers] Question about yield
- Ok, so around 4 liters of 92% alcohol from 8 kg of sugar.
Well, I'm still pretty far below, but not by more than perhaps 1 liter
But 4 liters of 92% alcohol is a pretty bad result also, as the
mash then only would be barely 15%, and it should be closer to 20 than
