single vineyard in the municipality of Erbach in the German wine-growing region of Rheingau. The name dates back to the 13th century and is a reminder of the "Markenburne" well on the boundary between Erbach and Hattenheim. A curious border dispute arose between the two municipalities over this in 1810, which is still visible today. The municipality of Erbach had the following inscription carved in stone on its side of the fountain: Marcobrunn Gemeinde Erbach. In response, the people of Hattenheim wrote on their side of the fountain: " That's the way it is, that's the way it should be. For Erbach the water, for Hattenheim the wine. The name Marcobrunn was already a sign of quality in the 18th century and was mentioned on bottle labels as early as 1726.
