Black and Tan is a style of beer made from a blend of a pale ale and a dark beer such as a stout or porter. Sometimes a pale lager is used instead of ale; this is more usually called a half and half.

The style is believed to have originated in pubs in the British Isles with drinkers ordering a mix of Guinness and Bass ale. The name is first recorded in 1889, though an earlier origin of an 18th century blend of porter and pale ale has been conjectured. Several American breweries currently make pre-mixed Black and Tan, and it is a popular blend at American bars. One of the oldest and best known commercial examples is Yuengling's Original Black and Tan. However, British breweries do not make it, and it is rarely requested in pubs.
