The organ built by Gebrüder Oberlinger Orgelbau in 1997 for St. Martin in Cochem includes an innovative stop called Riesling 2fach. Pulling the stop opens a small cabinet holding two bottles of Riesling wine.
This according to “Neue Orgel in der Pfarrkirche ‘St. Martin’ zu Cochem/Mosel” by Wilhelm Basten (Die Auslese 42/2 [1999], pp. 22–23).
