Which type of drink is a Salty Dog classified as?

A Salty Dog is classified as a highball. This type of drink typically consists of a spirit base combined with a larger proportion of a non-alcoholic mixer. In the case of a Salty Dog, the primary spirit is vodka or gin, and it is mixed with grapefruit juice. The unique element that defines it is the salted rim, which adds a distinct flavor contrast.

Highballs are known for their straightforward preparation and refreshing quality, making them a popular choice at bars. They are typically served over ice in a tall glass, further aligning the Salty Dog with this classification.

A cocktail generally involves a combination of spirits and other ingredients, often with more complex preparation methods, which doesn't fully represent the simplicity of a Salty Dog. Mocktails are non-alcoholic beverages designed to mimic cocktails, so they wouldn’t apply here, given that a Salty Dog contains alcohol. Sour drinks typically feature a spirit with citrus juice and a sweetener, but the emphasis on the type of glass and the preparation method aligns more closely with highball standards for a Salty Dog.
