Watch it made

U-Boot (Beer and Vodka Drop)

Taste

Crisp, malty beer with a clean alcoholic warmth that grows toward the bottom of the glass as the vodka mixes in.

History and origin

U-Boot is German for submarine, and the name describes exactly how the drink is served: a filled shot glass is lowered into a larger glass of beer so that it sits on the bottom. Similar drop drinks exist in many countries, from the American boilermaker, where a shot of whiskey is dropped into beer, to the Korean somaek of soju and beer and the Russian yorsh of beer and vodka.

The U-Boot is not a bartender's creation with a known history but a pub and party serve, and there is no documented inventor. What unites all these drinks is that they combine a beer with a spirit in one glass, which makes them considerably stronger than beer alone, so they are best taken slowly rather than downed in one.

Bartender tips

  • Use a sturdy shot glass and never drop it from high up: a glass hitting glass can chip or break.
  • A light, crisp lager or pilsner works best; dark or strongly hopped beers clash with the vodka.
  • Keep the vodka at a single 20 ml measure; the drink is already clearly stronger than a normal beer.

Variations

Somaek
Korean mix of soju and beer, often made with a shot glass balanced on or dropped into the beer glass.

Frequently asked questions

Why is it called U-Boot?

Because the small shot glass sits at the bottom of the beer glass like a submarine and only comes up as the drink goes down.

How strong is a U-Boot?

With 330 ml lager and 20 ml vodka it contains roughly as much alcohol as one and a half beers.

What beer is best for a U-Boot?

A cold, light lager or pilsner. It keeps the drink crisp and lets the vodka blend in smoothly.
