As to your (implied) question why humidity affects cigar flavor, I think it has to do with the oils inside the tobacco leaf. Too dry or too wet and the oils don't come across the same way when burned. I've read where this is more of a factor in long term aging than in keeping your cigars ready to be smoked. More educated folks on here are welcome to chime in & correct me if I'm off base.

What makes for proper humidification is mostly personal preference. My "premiums to be smoked" humidor runs from 59-63%, my cc sits around 60% and my cooler is at 70%. Seems to work for me, and I've never had any problems, but I don't worry too much about it, either (now that my leaky glasstop is fixed.)
