A well drink is a common term used in bars and restaurants to describe a cocktail made with the establishment's house or well liquor, which is typically the lowest priced and most basic type of alcoholic beverage. However, there are several other words that can be used interchangeably with the term "well drink." Some of these synonyms include rail drink, house cocktail, basic libation, standard pour, or simply a standard cocktail. Whatever the name may be, the concept remains the same - a simple cocktail made with the establishment's most affordable liquor.
