Citron
A source of confusion is that "citron" or similar words in French (and other languages), and English are false friends, as they refer to the lemon. Indeed, into the 16th century, the English name "citron" included the lemon and perhaps the lime as well.
Absolut Citron
Absolut Citron is one of the major core flavors of Absolut Vodka. The name means "lemon" in Swedish, and it is made from citrus fruits. It is crafted from Swedish winter wheat and water comes from deep well in Åhus. Absolut Citron was launched in 1988.
The drink is best suited for cocktail cosmopolitans and among many other drinks.
