The Brewery Museum was founded in 1986 by the Union Brewery. The material was collected by workers who wanted to preserve objects and documentation related to beer brewing and was an important contribution to the conservation of the city's technical heritage.
The permanent exhibition is displayed across more than 600 square metres of exhibition space and illustrates the development of the Pivovarna Union brewery from its foundation in 1864 to the present day showing the procedures of making and marketing beer, showing the cultivation of hops, the standard ingredient of beer, the malt house, the mashhouse, the fermenting and lager cellars, filtration, the bottling plant, the barrel store, transportation, pub furnishings, labels and advertising. Some of the objects were donated to the museum by workers from their private collections, while others were contributed by other breweries in the former Yugoslavia, by the Institute for Hop Growing and Beer Brewing in Žalec and by publicans.
For the preservation and promotion of the cultural heritage in its museum, the Union Brewery received European Museum of the Year Award (EMYA) in 1989 for special achievement, handed out by the European Museum Forum and a special award from the Council for Cultural Co-operation of the Council of Europe.
