I believe it is 90% marketing and 10% people sucking at talking. But scientifically it is possible for the same molecule that is responsble for say, the taste of citrus, to be found in a cigar. Whether this happens at a discernable level is a matter of debate (obviously). Again, marketing and people talking out their ass. Also, complex flavors like leather and oil are more difficult to describe than one dimensional flavors. I love the art/science barrier. Sometimes a cigar is just a cigar.
