A salty dog is a cocktail of gin, or vodka, and grapefruit juice, served in a highball glass with a salted rim. The salt is the only difference between a salty dog and a greyhound. The Greyhound dates to at least 1930, when it appeared in Harry Craddock’s "Savoy Cocktail Book" as a simple cocktail combining gin, grapefruit and ice.
Kir is a popular French cocktail made with a measure of crème de cassis topped up with white wine. In France it is usually drunk as an apéritif before a meal or snack. There are also many variations of the kir, the most notable being the kir royale, which uses Champagne or Prosecco. There are other versions that use cider or different liqueurs as well.
