The estate is located in the municipality Mertesdorf-Lorenzhof directly on the Ruwer in the German wine-growing region Moselle
, The Karlsmühle is considered the oldest stone mill north of the Alps. Nearby you could find remains of buildings that suggest a Roman mill. The Romans sawed here from Italy brought in marble and shell limestone slabs for the magnificent buildings in Trier. The Roman poet Ausonius
(310-395) describes in his around 370 resulting poem "Mosella" a boat trip on the Moselle and its tributaries. In it, he also reports of the Ruwer: The Ruwer turns in vortex swirling the grain-grinding stones and pulls the screeching saws through smooth marble blocks
. From 1457 the mill was owned by the monastery of St. Maximin in Trier. Johann Karl acquired it in 1803 at the dissolution of the monastery and gave it the present name. Since then, the family and their descendants have been growing wine. In 1889, Peter married Geiben into the family, whose eponymous grandson manages the estate since the late 1970s. The property also includes a hotel, which is currently leased.
The vineyards cover 12.5 hectares of vineyards in the individual layers Kehrnagel
(Chasuble), as well as the owner-owned very steep terraced slopes Felslay and Mäuerchen (Lorenzhof). The wines of the latter two individual layers are but mostly under the collective name Lorenz Höfer
marketed. The vineyards are largely with the Riesling (11 ha), as well as smaller amounts Müller-Thurgau, Pinot Blanc, Dornfelder, Pinot Noir and the special Moselle variety Elbling
planted. The Rieslings are usually spontaneously fermented with the natural yeasts and largely dry and semi-dry expanded. In weather-appropriate years also ice wines and Trockenbeerenauslese be pressed. It also produces bottled fermented sparkling wine.
