Clemens Busch is widely acknowledged as one of the top producers in Mosel. His wines are simply superb.
"The 2020 Marienburg Raffes is pure, very intense and fresh on the crystalline nose, with popcorn, mocha and crushed slate aromas. Silky, lush and generous on the palate, this is a full-bodied, dense, intense and refined yet crystalline and saline, firmly structured and very sustainable Raffes with fine tannins and a long and promising finish. This is a highly complex dry Riesling that is not as soft or as feminine as the Felsterrasse but behaves like the Hermannshöhle to the Dellchen. More aristocratic and shy rather than generous and tender. 12.5% stated alcohol. Natural cork. Tasted at the domaine in July 2022."
