What is "soplica"

Soplica is one of the older brands of Polish pure and flavoured vodka, having been first produced in 1891 (in a factory that was opened in 1888). Although the origins of vodka in Poland can be traced back to as early as the 8th century, Soplica is one of the older industrially produced brands of vodka in the country. Żubrówka, for example, is based on a much older recipe than Soplica (dating back to the Polish-Lithuanian Commonwealth) but exists as an industrially produced brand only since the 1920s.
