Guinan prepared a concoction containing mostly Saurian brandy along with Targ milk and Denevian mead, after hearing about it on Prakal II. Data observed that the drink contained a high concentration of fructose and monosaccharides (which is to say, it was sweet). (TNG: "In Theory")
When trying to distract Doctor Bashir from his dealings with Elim Garak in 2370, Quark asked Bashir if he wanted "a little Saurian Brandy to go or maybe a late-night in a holosuite." (DS9: "The Wire")
In 2371, Quark later ordered some Saurian brandy to have delivered to his quarters while he was conducting a negotiation with Emi. Rom, who was to deliver the brandy, instead warned Quark to leave immediately, as Grand Nagus Zek had arrived. (DS9: "Prophet Motive")
In early 2374, Nog managed to aquire some Saurian brandy for the USS Defiant crew despite the Dominion War going on. (DS9: "Behind the Lines") Later that year, Quark received a shipment of Saurian brandy. (DS9: "Resurrection")
In 2375, a Ferengi named Gant had ten cases of Saurian brandy for sale, and according to Nog, it was Benjamin Sisko's favorite.

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)
Quark often had bottles resembling Saurian brandy on his shelves in his bar on Deep Space 9.
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 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.
