<P> To prepare a Black and Tan, fill a glass halfway with pale ale then add the stout . The top layer is best poured slowly over an upside - down tablespoon 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 . Alternatively, the stout can be poured first so that the drinks are thoroughly mixed together . </P> <P> Several American breweries currently make premixed Black and Tan, for example Yuengling's Original Black and Tan . </P> <P> The name "Black and Tan" is not used in Ireland as a term for a mixture of two beers . The drink is instead referred to as a half and half . Indeed, the drink has image problems in Ireland and elsewhere due to the association with the Royal Irish Constabulary Reserve Force, nicknamed the "Black and Tans", which was sent into Ireland in the early 1920s . As a result, in Ireland the name is seen as contentious and disrespectful . </P> <P> In March 2006, Ben and Jerry's released an ice cream flavour in the United States for Saint Patrick's Day inspired by the drink; the name offended Irish nationalists because of the paramilitary association . Ben and Jerry's has since apologised . A spokesman told Reuters, "Any reference on our part to the British Army (sic) unit was absolutely unintentional and no ill will was ever intended ." In March 2012, the drink's name once more came into the news when Nike, as part of an Irish themed set of designs, released a pair of shoes advertised as the "Black and Tan" and generating offence similar to the earlier Ben and Jerry's ice cream . </P>
