Kilju is a Finnish word that refers to a homemade alcoholic beverage. It is similar to moonshine in the United States. Other synonyms for kilju include fusel, hooch, swipes, bootleg, and white lightning. Kilju is typically made by fermenting sugar, yeast, and water, and it can be flavored with different fruit juices or extracts. However, because it is homemade, the alcohol content can vary greatly, and it is often associated with illegal production. In Finland, it is illegal to sell or distribute kilju without a license, but some people still make it for personal consumption or to share with friends.
