I found this and made one yesterday that's just awesome. Cost about 40-50bucks to make if you have the pot already and it seemed to make about 6 batches which looks like 3 gal. It's really easy but a little time consuming. I would recommend doubling the batch to speed it up if you have a giant pot. If you join archerytalk you can watch the guys step to step pictures. I'll post my own finished one later I made grape vanilla.
