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 Coast, the second largest plum-growing area in the world. "Slijvovica" is the common name for Croatian plum brandy from former Yugoslavia. Traditionally this spirit is double-distilled and has been famous since the Middle Ages. The fruit comes from trees never less than 20 years old and the mash is fermented for three 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. Maraska is certified Star-K and is therefore Kosher for Passover.
