U-boot (cocktail)

A U-boot is a beer cocktail that is made by placing a shot of vodka into a glass of beer, typically a lager. It is popular in Germany, Poland, North Macedonia, and Flanders. In Germany, the liquor korn is sometimes used instead, while in Flanders and the Netherlands, jonge jenever is preferred.

It is called a U-boot (German abbreviation of Unterseeboot, "submarine") because the shot glass of vodka sinks to the bottom of the glass of beer. The shot glass then "surfaces" when the cocktail is drunk. Place a pint glass over the two glasses so it sits against the shot glass and flip them over. Fill the pint glass with lager and as the drink is consumed the vodka will leak into drink.
