Vesper
A Vesper martini was an alcoholic Earth beverage, enjoyed by both Jett Reno and Commander Rayner when served "ice cold".
While time jumping as a result of a Krenim chronophage in 3191, Commander Rayner encountered Reno aboard the USS Discovery in 3189 where she saved him from an Emerald Chain regulator. She assured him he could repay the debt by "buying" her a Vesper martini at Red's, and the two agreed "ice cold" was the only way to enjoy them. (DIS: "Face the Strange")
