The Brömserburg in Rüdesheim is one of the oldest castles along the Rhine River. The former fort, which was once surrounded by water, was built around 1000 AD as a stronghold of the Electorate of Mainz. Since 1950, it has housed the Rheingau Wine Museum.

The castle which was built in 12th century, offers the world's oldest wine-related collection, ranging from wine- and drinking-vessels made out of different materials over bottles and labels to tools and equipment used by coopers, cellar men and wine-growers. There is also a wine-distillery installed true to the original.

Besides offering information on the history of wine, the Brömserburg also gives visitors the opportunity to try different wines.
