The 2015 Nackenheimer Rothenberg Riesling Trockenbeerenauslese displays a clear and mineral nose of concentrated, but still clear Riesling and lemon flavors. Noble, rich and elegant on the palate, this has a fine and salty acidity. It is an enormously sweet, very intense and piquant TBA with a delicate acidity that combines its immense richness with citrus flavors, vitality and finesse. However, readers should store this extraordinary TBA for 10-20 years to reduce the richness, and receive more transparency and elegance.
