I have a pretty solid understanding of the processes involved in distilling, but I keep trying to gauge production run sizes into the still, and linking it back to actual yield.
I am going to use round numbers to start to make it easier.
If I create a 100 Gallon sugar wash that is 10% ABV at the completion of fermentation. There is 10 gallons of ethanol contained within. The best I could hope to extract is 94% of that so 9.4 gallons of pure ethanol, but realistically if I am using a pot still and with about 85% efficiency, for a single pass distillation. I am likely to only get 7.99 gallons of pure ethanol out (but lets round up to 8 to keep the math simple). I know that I am not going to distill 100% ABV, and will probably get something starting around 180 and tapering down. If I am extracting at around an average ABV of 70%, should I reasonably expect the yield to be approx. 11.4 gallons? Or even just proofing down whatever results from the distillation to an average of 100 proof to have a yield of about 16 gallons?
Am I thinking correctly?
