Bob Luken:Just a guess, but I'd say that it is likely a construction problem that is made worse by the humidity. Just a guess. A long time ago I asked a question about burn problems keeping an AB Prensado lit during high humidity and the majority of the replies told me it AB Prensado's fault and was not related to the humidity outside where I was smoking. But here lately I've seen a bit of talk from guys on here who talk like humidity does make a difference in general. And that would make sense to me. There's more oxygen at high humidity and less at low. You need three things to make fire. Source of ignition, (lighter) check. Fuel (cigar) check. And oxygen, check, wait wait. Do I have TOO LITTLE oxygen or TOO MUCH oxygen? Sure I might be able to force it burn. But with the oxygen available, will it burn well enough to enjoy the flavor?
bigharpoon:I notice a big difference in burn when the humidity is high regardless of brand or shape. The cigars just seem to be absorbing moisture at a rapid rate and before I know it my cigar acts like it's plugged and I have a wonky burn. It affects the flavor, too, as you aren't going to get all the cigar has to offer with a bad burn. In Maine humidity is a fact of life but when I smoke in those conditions I just pay extra close attention to my cigar because I know it won't take care of itself with ease.
kuzi16:part of the reason why cigars burn well is the relationship between the binder and the wrapper and then again the relationship between the binder and the filler. too much of a gap between anything and the wrapper and the cigar wont burn correctly. Box pressed cigars are made just like regular cigars with a touch less tobacco so that it can take to the press without splitting the wrapper or binder. this press changes the relationship of the binder, wrapper, and filler. the trick is to fill the cigar correctly, a task that is difficult with a regular cigar let alone a box pressed one. the best box pressed cigars dont have this issue.
