43.6g/l RS, 10g acid, 7.5% alc. Krettnacher Altenberg and Euchariusberg are two of the top-ranked sites on the Saar; steep, well-situated, and slatey. But Altenberg is much smaller, cooler, and in addition to its foundational blue-grey slate, contains the exceedingly rare "green slate" known as Diabas. This vivid Kabi teems with fresh aromas of apples and tangerines, and holds its sweetness in a precise structure, destined to age beautifully. While not exactly a unicorn, it is still a precious and rare exemplar of ultra-filigreed Saar Riesling.
