"The sloping vineyards of the Leistenberg are characterised predominantly by clay slate soils. This dry, blackish-grey slate is perfect for producing superbly elegant wines. Our characterful dry Riesling wines from these soils are therefore named after this ancient rock. Tonschiefer translates as clay slate. Full-bodied, mineral Riesling wine with a fruit nose of great finesse and classic acidity." Dönnhoff
