Alcoholic beverages

In some cafés in Brussels, a "half en half", Dutch for "half and half", is a mixture of white wine and champagne." Originally, it was a mixture of two different typical beer types from Brussels: 50% lambic and 50% faro."
Denmark
If you order a "half and half" in a Copenhagen bar, you will get a mixture of dark beer and pilsner. The dark beer is a Danish version of an Imperial stout-type beer – in Denmark simply called "porter", which is a little sweeter than a Guinness.
In Britain, a half and half may mean a mixture of mild ale and bitter. In the North East of England, a request for a half and half would more commonly produce a combination of Scotch ale and India pale ale. This drink fell from favour when the Scottish & Newcastle brewery were obliged to sell many of their tied public houses and McEwan's Scotch and IPA disappeared from public bars across the North East. In Canada and the United States, Black and Tan refers to Guinness and a lager or ale that will support the Guinness, most commonly Bass Ale, although some Irish-themed bars shun the term for its association with the Royal Irish Constabulary's "Black and Tans" force. A Half and Half is Guinness and Harp. A Guinness and Smithwick's is a Blacksmith.

Switzerland
In Switzerland, and more particularly in Valais, a half & half is a mixture of dry and sweet liquor of the same fruit.

Uruguay
In Uruguay there's a beverage called "Medio y Medio" that consists of sweet sparkling wine and dry white wine in equal parts. "Medio y medio" comes in Red, Rosé and White varieties, the latter being the original and most popular. It is massively consumed during the holidays but it can be found in certain places throughout the year as well. The most common "Medio y Medio" is the one produced by Roldós, a local restaurant that claims having invented the mixture. "Medio y medio" is also the name for another cocktail, made with White Vermouth and "Caña", a 35–50% alcoholic beverage distilled from sugar cane. This name, however, is used not in the majority of bars but only in the most traditional ones, probably due to the existence of Roldós' "Medio y Medio".
