Vineyard in the municipality of Graach (Bernkastel area) in the German Moselle wine region. In terms of wine law, this is not a single vineyard site, but a single vineyard site free district. It was already mentioned in documents in the 10th century. The name is derived from the single farm settlement Josephshof, which is located just outside and northwest of Graach and was a former monastery estate. For almost a millennium, the estate belonged to the abbey St. Martin from Trier, that is why it is still called "Merteshof" today. In the course of secularisation under Emperor Napoleon (1769-1821), Matthias Joseph Hain from Trier bought the estate at auction in 1803 for 247 florins and gave it its present name. His son-in-law Mohr sold the estate for 58,000 thalers to the Count of Kesselstatt. Since then the vineyard has been in the monopoly possession of Count von Kesselstatt.
This vineyard is also said to be the first vineyard on the Moselle where the Hungarian method of producing an outbreak is said to have succeeded. The south-facing vineyard at an altitude of 120 to 170 metres above sea level with a gradient of 50 to 70% comprises 5.7 hectares of vines on deep, stony Devonian slate weathered soil with a high proportion of fine soil. It lies between the Wehlener Sonnenuhr and the Graacher Domprobst. Only the Riesling variety is cultivated here. The wine is marketed as "Josephshöfer" (without the name of Graach), which documents its special status.
