Wrappers do constitute the majority of your flavor.

As for pre-embargo, don't waste any money, even if they can authenticate them, the shelf life of a cigar is about 50 years. It'd be like paying for the 2000 dollar bottle of 1940's burgundy just to say you have the 1940's burgundy, it's content is really more like vinegar than alcohol at this point, but hey, it's still a 1940's burgundy. Similarly with a cigar, even if kept in prime condition, tobacco ages, but only to a point, which is approximately 50 years. The longer it ages though, the less flavor it will have as the oils evaporate. Which means unless these pre-embargos were the strongest cigars ever produced, they'll be like smoking macanudos by this century easily.

As for the more common "pre-embargo" cigars, the pinars (typically 8-12 a stick) I just don't buy the story of "we found a stash of tobacco in a warehouse after 40 years." Even if true, who's to guarantee the tobacco was kept in ideal conditions all that time, and even if it was, the above problem occurs. Finally, to claim that it is a pre-embargo cuban, legally they'd only have to have less than one percent of the cigars total make up actually from pre-embargo leaf in order to keep the claim. It's not false advertising if some part of it is pre-embargo leaf.

So, nobody should ever waste their time with these.
