. It is named after the castle of the same name, which was restored at the end of the 19th century. The southwest-facing vineyards at 100 to 230 metres above sea level have slopes of 45 to 60%. The foot of the slope is only 150 metres above sea level from the Rhine. Riesling is the main grape variety cultivated here. The castle and the site are solely owned by the pharmaceutical entrepreneur Werner Siekmann; the vineyards are leased to a group of winegrowers from Kauber.
