Any brand of liquor that a customer must ask for by name in a restaurant or bar, instead of the more generic and less expensive house brand.
"Call for another round of Captain and Coke." Here the person is directing someone to order them a rum and Coke, and is asking for Captain Morgan Spiced Rum (the Call Brand) instead of the less expensive Well Brand kept under the counter.
