I had a business venture going on with someone for a while and we were making it, but ended up selling off our equipment and moving on because we weren't producing enough at the time to make it financially worth it.
I know there are random guys that brew the stuff in small amounts, but as far as I am aware, there isn't anyone around here making it in large quantities.
And last I knew, buying it from a gas station or major manufacturer was as expensive, if not more expensive than regular diesel.

that said, what do you need it for?
