Maraska Slivovitz is a pure, natural brandy made by special fermentation and distillation of the finest ripe blue plums grown in the rich soil of the Adriatic Hinterland, the second largest plum-growing area in the world. Slivovitz is the common name for Croatian plum brandy from the former Yugoslavia. Traditionally, this spirit has been double-distilled and has been famous since the Middle Ages. The fruit comes from trees no less than 20 years old and the mash is fermented for 3 months in large 2,000-gallon tanks. After a second distillation, it is matured in specially treated 500-gallon oak casks for a minimum of 2 years. Kosher Slivovitz is made under strict kosher guidelines that allows this brandy to be Kosher For Passover.
