KOSHER FOR PASSOVER Troyanska Slivovitz kosher 4 years old is a unique beverage that originated from traditional production methods in conjunction with the stringent rules of representatives of the American Orthodox Union. For this masterpiece, RUDOLF JELINEK allows an extra 4 years for aging, thereby achieving the highest possible quality fruit distillate. As it ages in the barrels it gets its distinctive color and aroma reminiscent of cognac or brandy, while still retaining its typically fruity flavor which is enriched with woody undertones.
