Black and Tan is a beer cocktail made by layering a pale beer (usually pale ale) and a dark beer (usually stout). In Ireland, the drink is called a half and half.
A Black and Tan is prepared by filling a glass halfway with pale ale, then adding stout to fill the glass completely. An upside-down tablespoon may be placed over the glass to avoid splashing and mixing the layers. A specially designed black-and-tan spoon is bent in the middle so that it can balance on the edge of the pint-glass for easier pouring. The "layering" of Guinness on top of the pale ale or lager is possible because of the lower relative density of the Guinness.
Several American breweries currently make premixed Black and Tan, for example Yuengling's Original Black and Tan.查看更多两种成分的鸡尾酒。
