Bloodwine is a popular alcoholic beverage among the Klingons, best served warm. As with many Klingon foods and beverages, it is not for the faint of heart. Bloodwine is known to be highly intoxicating, to the point that most non-Klingons are scarcely capable of handling it; it is twice as potent as whiskey. (VOY: "The Killing Game, Part II") Klingon captains and generals are fond of carrying several barrels of their favorite vintages to celebrate victories. Martok considers the vintage of 2309 to be the finest. (DS9: "What You Leave Behind") Worf likes his bloodwine very young and very sweet.
- Whether there is actual blood in the ingredients has never been revealed, however, the Star Trek Cookbook suggests that bloodwine is made of fermented blood and sugar.
- During an interview with Michael Dorn, he explained that blood wine used during filming is actually fruit punch with added red dye to darken it.
