The 2008 Eroica Riesling from Michelle Loosen in Washington State has11.5% alcohol (hidden in tiny print on black along side the label as well as being a bit high for Riesling) cost under $20 then, and scored a pleasant 15 points on the Dionysian scale of a possible 20.
It is made by Germany’s Dr. Loosen, but the color was not as rich and was unlike true German 12-year-old Rieslings. It served as a learning experience. It was enjoyable, but it seemed the sugars were not balanced with enough acid.
All quality Riesling should last at least ten years I am not certain that this example is worth it. In Vino Veritas.
