Dr. Loosen Riesling “Red Slate” Trocken 2018, "Smoky and stony notes mingle with fresh apple and lime on the nose, and that cast of characters reemerges on a polished palate to deliver tangy animation and considerable mineral interest. Erden-typical green herbal notes add to the appeal, and this finishes with admirable persistence as well as more than adequate refreshment.
(This bottling, sourced primarily from Erden and Lösnich, is known as “Rotschiefer” in German-speaking markets.)" - David Schildknecht, Vinous
