Krupnik is a traditional sweet alcoholic drink similar to a liqueur, based on grain spirit (usually vodka) and honey, popular in Poland and Lithuania. In Poland it is grouped in the nalewka category of alcoholic beverages.
Mass-produced versions of krupnik consist of 40–50% alcohol, but traditional versions will use 80–100% grain alcohol as the base. Honey, usually clover honey, is the main ingredient used to add sweetness, as well as up to 50 different herbs. There are many versions and some recipes have been passed down through generations; producers typically use their own recipes.
At times, spicy seasonings and herbs are added for flavor. The brand of the honey and the ratio of seasonings are key factors which determine the final taste of krupnik. A mixture of the honey and spices is diluted, boiled and strained before being added to a vodka base.
It may be served hot, at room temperature or chilled.
