The historic Maximin Grünhaus estate lies at the foot of a long, steep south-facing slope on the left bank of the tiny Ruwer river, about two kilometers upstream from where it joins the Mosel. The estate belongs to the family of Carl von Schubert and is divided into three separate but contiguous vineyards: Abtsberg, Herrenberg, and Bruderberg. Each of these vineyards has its own distinct differences in terroir, which explain the unique character of the wines made at Maximin Grünhaus. The first documentary evidence of Grünhaus, then called "Villa ad Valles," dates from February 6, 966. Emperor Otto I, heir of Charlemagne, confirmed a donation that had been made in the Seventh century by the Frankish King Dagobert. At that time, the buildings, vineyards and surrounding land had been given to the Benedictine monastery of Saint Maximin in Trier. In 1882, it was purchased by an ancestor of Carl von Schubert, who is the fifth generation of his family to own the Grünhaus estate.
