Hmmm, good question. I thought that most of the domestic crop of cigar leaf was wrapper. To my surprise, Connecticut is a major wrapper leaf growing state. I don't know that filler is grown much in the U.S. I buy my cigar leaf from C&D, and I supposed that it was the Connecticut wrapper leaf. It has a good robust cigar-flavor, although in a pipe, cigar leaf is still pipe tobacco. These are two different smoking experiences, and I prefer pipes; the the occasional cigar is fine. Some educated tobacconist may post here to clarify my guesswork, I hope.
