Salmiakki Koskenkorva, (also Salmiakkikossu for short, or Salmari more colloquially) is a pre-mixed liqueur popular in Finland.
Salmiakki Koskenkorva is a somewhat viscous black liquid, or a dark grayish brown when of a thinner consistency.
The concept of mixing vodka and liquorice probably existed long before the 1990s, since both Koskenkorva Viina and Tyrkisk Peber were around before the alleged invention of the cocktail.
A well-known anecdote says that singer Jari Sillanpää invented the drink when he was working as a bartender in the late 1980s.
The taste of Salmiakki Koskenkorva strongly resembles that of black liquorice and cough medicine.
