Site & Terroir Vineyard: The Geisenheimer Rothenberg was first mentioned by the nobleman Ruthard de Rothenberch in 1145. The name could be derived from two other possibilities: "Rodenberg" in the sense of "to clear" or "to make arable," or it could refer to the red color of the soil. The vineyard covers 44 hectares, of which 5.44 hectares are classified as "Große Lage." With a south-southwest exposure and a slope of approximately 40%, it is arguably one of the winners of climate change. On the world's oldest vineyard classification map, dating from 1867 and rediscovered in 2011, this site is already listed as one of the Rheingau's first-class vineyards. Since 2005, this vineyard has set the German must weight record three times. In the record year of 2011, Rothenberg harvested TBAs with must weights of 259°, 319°, and an incredible 340°. 2015, 2016, and 2017 are the most recent vintages with optimal conditions for TBAs. Must weights of 170°, 190°, and 230° were harvested, respectively. Terroir: Taunus quartzite, interspersed with red slate (iron oxide).
