What juice is typically used in a Salty Dog cocktail?

A Salty Dog cocktail is typically made with grapefruit juice, which is the correct choice. This cocktail features the combination of vodka and grapefruit juice, served in a glass with a salted rim. The salt enhances the flavors of the grapefruit and balances the bitterness, creating a refreshing and tangy drink that is popular in many bars.

While other juices such as orange juice, lemon juice, and tomato juice can be used in various cocktails, they do not define the traditional flavor profile of a Salty Dog. Orange juice might be more familiar in drinks like the Screwdriver, while lemon juice is often associated with cocktails like a Whiskey Sour. Tomato juice is primarily used in drinks such as a Bloody Mary. Each juice has its distinctive taste, but the refreshing bitterness and tartness of grapefruit juice is what characterizes the Salty Dog.
