So earlier today I read a thread where, somewhere in the middle, the experiment was suggested of taking two jars of the same tobacco and cellaring both for five years. One jar would be left untouched, the other popped open and given a little fresh air once a year. I should have replied then, and now I cannot find it. Who was it, are you out there? I'm just starting to build a cellar, but I think this could be fun.
