Tobacconist University
This term should refer to the year a tobacco leaf in a particular cigar or pipe tobacco is harvested.  In most retail brands, the vintage (i.e. 1993) refers to a specific leaf/component like the wrapper, binder or filler(s) grown in a specific year.

In the absence of provenance or appellation-like standards in the cigar/pipe industry, there can be some ambiguity when the term vintage is used. Some cigar makers can misuse the term simply to make their cigars seem older or more attractive.   Also, see Estate VintageClick here to learn about a true vintage cigar.
