Haus des Deutschen Weines, Wine institute building at Gutenbergplatz, Mainz, Germany

The Haus des Deutschen Weines is a building in Mainz dedicated to German wine culture, combining dining and educational facilities under one roof. The structure features gray stone walls decorated with heraldic symbols representing wine-producing regions throughout the country.

The building opened in 1958 and was created to bring together and share knowledge about German wine regions in one place. Its founding reflected a wider effort to promote wine culture and the wine industry across Germany and present them internationally.

The German Wine Academy, based in the building, initiated the Mainz Wine Study, which asked how moderate but regular drinking of German red and white wine affects coronary heart disease. The academy describes itself as a mediator between science, business and consumers. The building also housed the German Wine Institute and the German Wine Fund until 2016.

The ground floor holds a restaurant with a terrace overlooking the Mainz State Theatre and provides direct access to wine-tasting sessions. The location sits centrally in Mainz and is easy to reach, especially when exploring other sites around Gutenbergplatz.

The institute carried out a large study examining the link between moderate wine consumption and heart and blood vessel health. This research connected scientific questions to the everyday lives of people who drink wine.
