Starka is a traditional dry vodka distilled from rye grain, currently produced only in Poland. A Starka-flavoured vodka is also produced in Lithuania. Traditional Starka is made from natural (up to 2 distillations, no rectification) rye spirit and aged in oak barrels with small addition of lime-tree and apple-tree leaves. The process of production is similar to that used in whisky. Sold in various varieties, the most notable difference between them is the length of aging period, varying from 5 to over 50 years, and the natural colour which is taken from the long reaction between alcohol and the oak, not from the addings.
