Actually I have a theory that a cigar with higher moisture content for an extended of period of time will be a better cigar in the long run. I believe moisture is the only way diffusion will happen from leaf to leaf. Very much like how soup and other foods taste better the next day. So if a cigar has higher initial moisture content and allowed to dehydrate slower then it seems to me that you'll get a better blending of flavors.
I'm sure there is fermentation going on at some level and I don't want that in a finished cigar, however, I'd hope not much. Ammonia is one of many gasses produced as a result of tobacco fermentation
and I sure don't want that.
I don't know what moisture level it takes to cause fermentation, other than to say I've cased leaf (probably more than I should have) from both suppliers which caused the leaf to smell of ammonia. Different leaf had different levels of smell. I've also noticed tightly packed leaf when cased higher than they should have been got warm.
Like I always say, if it works for you, keep doing it.
