Well drink
A well drink or rail drink is an alcoholic beverage served using the lower-cost liquors stored within easy reach of the bartender in the counter 'speed rail' or well. Rail drinks differ from "call" drinks in that the former are offered when a customer does not specify a particular brand of liquor when ordering a mixed drink. The terms "well drink" and "rail drink" come from the name for a bartender's workspace, known as either the well or the rail. In any given establishment, the rail/well liquors available may be known as the "house pours" or "house brands".
