Later that year, Hector Ilario experienced his first taste of Saurian brandy; he also stated that it was Captain Sisko's favorite.

The same Saurian brandy bottle that appeared on TOS would resurface in a 1971 episode of the Desilu/Paramount series "Mission: Impossible" entitled, "The Missile". In a move that had to be an intentional homage to Star Trek, the director prominently placed it in frame next to Leonard Nimoy.
