What an interesting thread made more substantive by the welcomed comments of Mr. Oliva.
I suppose it's not impossible that Dominican or Nicaraguan suppliers are sending tobacco into Cuba. The real question, of course, is whether or not it is used in any of the Habanos denomination of origin premium handmade cigars.
As to the claim that Cuban wrappers are unfermented? I find that impossible to believe. Unfermented tobacco leaves have 5-10 times the nicotine that fermented leaves contain. Even in as small a proportion by weight as wrapper, I cannot imagine a cigar containing unfermented leaf to be even remotely smokable.
Mr. Oliva's comment on the 90% RH claim is right on the button. Terroir and the effect it has on the expression of genetic traits is the most likely, most plausible explanation for the distinctive character of Cuban tobacco. This is, in fact, the "nature through nurture" perspective on growth and individuation that the great majority of developmental scientists hold.
It surprises me just a little that someone with such a depth of practical experience (i.e. the fermentation of Connecticut shade tobacco) could be so far off base on such fundamental technical items.

You're right mac. After rereading Wilkey's post I've just made an ASS of myself. Sorry Wilk. I thought your post was directed at me. Wilk please IM me your snailer. A making an ASS of myself bomb package will be sent out tommorrow. Sorry dude.
Wilkey, I think you should reread my reply to Joe's post more clearly (no where did I state that all Cuban wrappers are underfermented. What I stated was that not all Cuban wrappers as well as their non-Cuban brethrean are fermented PROPERLY). As to the last sentence of your above post I'm, frankly, taken aback. For the record I don't ferment "Connecticut Shade tobacco" (which, incidentally, goes through a box sweat and not the traditional Cuban style pilon sweat). For a better understanding of what my company does I would invite you to google Oliva Tobacco Company or Angel Oliva Sr. You obviousley have grown a lot of tobacco. I don't have to tell you or anybody else in my end of the business that a lot of tobacco (both Cuban and non-Cuban) goes to market inproperly cured and or underfermented. I have a rather extensive aged collection of both and see evidence of it everyday.
As to my technical expertise in curing tobacco I would invite you to ask anybody in the tobacco business (including the Cuban tobacco business, who incidentally have come to operations to see what we're doing) about or who is doing some of the best processing of tobacco in the world right now. It's the one aspect of our business we've staked our money and our reputations on.
