The Zwack Unicum Museum is sometimes referred to as the Hungarian national spirit. The signature wines of the Zwack Unicum family date back more than two centuries. The drink Unicum was originally invented in the late 18th century by the royal physician to King Joseph II of Hungary ( Joseph II) Dr. Zwack; It is worth noting that the history of this lively place is on display along with the largest collection of small bottles of alcohol in Central Europe in the Zwak Distillery.
