When I was young, I wold go and watch the older men that mad their own chewing tobacco. They would have either wooden barrels or burlap sacks and pack them full, then keep them in a spot that would stay hot, above 90 degrees and around 65-68% humidity. For small amounts, you need a kiln and I have a link that explains. I had zero luck with trying to get a small rubbermaid container to work when I tried a few years ago. Best of luck. Avoid getting the humidity at 70%, it will mold.
