Background information Edit
This drink was referred to as simply "brandy" in the final draft script of "The Enemy Within". The beverage received its full name in the revised final draft of that teleplay.
The "powder horn" bottles used in TOS and DS9 were originally commemorative whiskey bottles from the George Dickel Distillery in Tennessee, produced in 1964. (Star Trek Encyclopedia 2nd ed., p. 431; Star Trek: The Original Series 365, p. 45)
In a line cut from "The Die is Cast", Vice Admiral Toddman noted to Julian Bashir that he was "in trouble", because the Admiral had bet two cases of Saurian brandy that he was going to win the Carrington Award that year. Toddman told Bashir, "You lost, which means I lost. And I don't like to lose." (Star Trek: Deep Space Nine Companion - A Series Guide and Script Library)
The same Saurian brandy bottle that appeared on TOS later resurfaced 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.
