We had a bottle of Sorgum that we got in Kentucky at while we were at the NCOWS National last year (2006). It's never been opened and the other day I noticed the molasses were seeping out. My wife wiped off the bottle and set it by the sink and later some more was seeping out. We left the lid loose and in about two hours the stuff was crawling out the mouth of the bottle like it was alive. What's going on here? Is it fermenting?
