"Black and Tan" is a popular beer cocktail made by layering two different types of beer. Typically, it combines a dark beer, such as stout or porter, with a pale ale or lager. The dark beer is poured slowly over the back of a spoon to create a distinct separation between the two layers, resulting in a visually appealing drink. The name "Black and Tan" has historical roots, referring to the British forces known as the "Black and Tans" during the Irish War of Independence. However, the cocktail itself is enjoyed for its unique flavor profile, blending the rich, roasted notes of the dark beer with the crispness of the lighter beer.
