How much does it cost to produce 1 gallon of ethanol?
A. If you do this on a large enough scale, it will cost anywhere form $0.95/gallon to $1.40/gal to make the alcohol, depending on your feedstock. Look at my web pages, “Mashing and Fermentation” and also, “Molasses and Rum “. You will also have animal feed by-products which you can sell to reduce the total cost by another $0.40/gal.
