The Geisenheimer Rothenberg was first mentioned by the noble Ruthard de Rothenberch in 1145. The naming can be derived from two other possibilities: Rodenberg in the sense of making arable or clearing, or it refers to the red color of the soil. The size of the vineyard is 48 hectares, of which around 6 hectares are classified as "First Growths". With a south-southwest orientation and approx. 40% slope, it is probably one of the winners of climate change. On the world's oldest vineyard classification map from 1867, which was rediscovered in 2011, this vineyard is already listed as one of the 1st class vineyards in the Rheingau. Since 2005, this vineyard has set the German record for must weights three times. In the record year 2011, TBAs with must weights of 259°, 319° and an incredible 340° were harvested in Rothenberg. 2015, 2016 and 2017 are the last vintages with the optimal conditions for TBAs. The must weights 170°, 190° and 230° were harvested.
