Opus X release dates.

[troutbreath]

The names of the various Añejo vitolas (eg "No.48") are derived from the ring gauge of the cigar in question (except for the "Shark"; see below).

Añejo (which means "aged, refined" in Spanish) cigars were originally released in June 2000 (in a very small batch), and then again in December 2000 due to Fuente being skittish about whether enough Opus X tobacco would be available after the hurricane hit their farm in 1998.

Añejos have a blend of Opus X, Don Carlos, and Hemingway filler, with Connecticut broadleaf maduro wrappers that are cured in cognac barrels after they've been aged.
