The winery is located in the municipality of Pünderich (Bernkastel area) in the German wine-growing region of Mosel. The head office is in a half-timbered house built in 1663 directly on the banks of the Moselle, while the cellar, built in the 1970s, is further up the hill. The winery has been run by Rita and Clemens Busch since 1986. The vineyards cover 17 hectares of vines in the single vineyard sites Marienburg (in the plots Fahrlay, Fahrlay-Terrassen, Falkenlay, Felsterrasse, Raffes and Rothenpfad) and Nonnengarten (Pünderich). They are 99% planted with Riesling, as well as a small amount of Pinot Noir. Biodynamic viticulture is implemented according to the respekt-BIODYN guidelines. Particular attention is paid to strengthening the plants, which is achieved mainly through cover crop between the rows of vines, as well as in fertilisation through the use of exclusively natural nitrogen, clay minerals and plant extracts.
The grapes are only lightly crushed and pressed at low pressure. The best lots then ferment in old fuder barrels, others partly in stainless steel. Spontaneous fermentation is mainly practised with the vineyard's own yeasts; only for the production of Trockenbeerenauslese is pure-bred yeast used as an exception. The wines are stored for a long time on the full le es and are aged for up to 24 months. The premium wines include the local wine "Riesling vom roten Schiefer" and the Grosse Lage wine "Marienburg FAHRLAY". Fine brandies (yeast, marc, fruit) matured in oak barrels and bottle-fermented sparkling wines are also produced. Around 100,000 bottles of wine are produced annually. The winery has been a member of the VDP since 2007, as well as the associations La Renaissance des Appellations and respekt-BIODYN.
