The Zwack Museum is a very personal, intimate collection of photographs from the Zwack family but also a treasury of old posters and personal memorabilia dating back over two hundred years which tell the story not only of Unicum and the Zwack family. Here you can see the bottles and the machines of the past and the old distillery, which is called the heart of Unicum. It is located in Budapest at headquarters of the company where the production also happens.

For groups and individual visitors the program contains a visit to the old distillery as well, namely the "Heart of Unicum" which is now in its original condition since it has been renovated based on the original photos that remained. More than 100 years old distilling systems, stone barrels - used for extraction - and aromatic herbs that might be a part of the Unicum's secret recipe are exhibited in this tarnished building.
