How much feedstock does it take to produce one gallon of ethanol?
180-proof is 90% pure ethanol. To make it, start out with something cheap and readily available to make your own beer. I suggest you start with ordinary corn, wheat or barley, and start by following an ordinary recipe for making beer at home. Corn is best, with more starch. Grind it with a 1/8th inch screen mill (if it is too small, it is like flour and will ball up in water, so a course grind is better). For starters, use two 50-pound sacks of grain (40 kg). (I don’t suggest buying this on a regular basis, but just for your first run if you dont have anything else available for free).
