As an aside to this thread and only because it will help all our efforts:
All tobaccos continue to change throughout their shelf life. From first made to two years, they will change. All tobaccos must be steeped. Period. Some more so than others. It does not matter if its a forced steep via a crock pot, a UC, or left in a closet for a month. Just varied rates of change. I have tobaccos I like fresh, that I appreciate how they change over time. And I have tobaccos that need two weeks minimum before I touch them, and from there on I can appreciate how they mature. A crock or UC gets you there faster, in little time.
The key in both was the temperature and time used for both the crock pot and the UC. 150° constant temp for 4 hours. Both method produced consistant and very very similar results. Only a slight edge from the UC was noted. In the end, after numerous reviewers tried them, we all felt there was little difference of note between the two methods. Either method used will shave a little more than 2 weeks off wait time vs just putting it in a closet.
As I am the one who nailed down the process for steeping at or near 150°, I agree with Mike's findings and they were very scientifically done. The jury is out. Both UC and crock offers the same benefits. The key is constant temp and heat, as I have said for nearly 2 years now.
One hour in a UC is not enough to change a darn thing, much less if it isnt a heated UC.
