Snakebite is a cocktail that combines equal parts of lager beer and cider. When served with a dash of blackcurrant liqueur, it is called Snakebite and Black, Purple Nasty, or Diesel. The variation that includes a shot of vodka is known as Turbo Diesel while using stout instead of lager creates Poor Man's Black Velvet. The classic Snakebite is made by layering beer on top of the cider.
