Kitron is a traditional citron liqueur hailing from the Greek island of Naxos. It is made from citron leaves (Citrus medica) that are macerated in neutral alcohol. The macerate is distilled, and the spirit is then mixed with sugar and water.
Kitron typically comes in three versions that differ in color and strength. Green-colored kitron is the sweetest and has the lowest alcohol content (30% ABV). The colorless version is bottled at 33% ABV, while the strongest yellow-colored variety comes bottled at 36% ABV.
