Other than beer are there any fictional drinks that eventually became real? While reading this question (What other beer brands began as fictional but eventually became real?), I became interested in knowing if there are any fictional alcoholic drinks other than beer that eventually became real?
The Vesper Martini was first described by James Bond in Ian Fleming's book Casino Royale in 1953. The recipe is: 


  "Three measures of Gordon's, one of vodka, half a measure of Kina
  Lillet. Shake it very well until it's ice-cold, then add a large thin
  slice of lemon-peel."
