Clemens is the fifth generation winemaker at this estate. Clemens started working in his father’s 2-hectare estate in 1975 and has spent his career expanding the acreage and breadth of his holdings. He now works on 21ha, 12ha+ of which are on the prime slopes of the Marienburg. He stopped using herbicides in 1976, then in 1984 he and wife Rita converted to organics. They were among the first in Germany to commit to organic viticulture and led the movement establishing an association of organic growers in 1986. The estate converted to biodynamics entirely in 2005, earning certifications from the EU and Respekt-Biodyn.

The geology here is unique, based on a volcanic formation hundreds of millions of years old, manifested in a long, undulating cliff face that is nothing short of epic. The three main colors of slate (blue, red and grey) are all found here, dominating different parcels along the slopes across the river from the village. Clemens identifies the different terroirs of the original hillside on his labels by their historical names: Fahrlay, Falkenlay, Rothenpfad, Felsterrasse, and Raffes. He further delineates his wines by their soil type, using an ingenious method: the color of the capsule on the bottles indicates the type of slate (blue, gray or red) that dominates the source from which each wine comes.

Most of the wines at the Busch estate are vinified dry, and they are rich, complex and often powerful. They age very beautifully, gaining in complexity and texture. However, the sweet and noble sweet wines from the estate are also impressive, ranking among the finest wines made anywhere on the Mosel.
