Fresh lime and apple typical also of other wines in this collection mark the nose and palate of Kreydenweiss’s 2008 Riesling Kastelberg, accompanied by a greenhouse-like profusion of leafy and bittersweet floral notes. Palpably extract-rich, silken yet refreshing, this finishes with the addition of piquant toasted hazelnut and a decided lick of wet stone. A bottle open for five days was even more expressive aromatically yet more precise and thus in a sense more strict in its long, stony finish. This has enormous potential for further complexity and two decades of good health in bottle, predictions in which I note that three generations of Kreydenweisses concur. Antoine Kreydenweiss is now running his family’s Alsace domaine on an ongoing basis, while his father Marc concentrates on their property in the Costieres de Nimes. I was dismayed – especially in view of such high-quality 2009s and 2008s – to learn that this justly-renowned domaine for the time being no longer has a U.S. importer. Most of the 2008s received 15 months’ elevage. The 2009s were all harvested early even by vintage standards and harbor nuances not found in most Alsace wines of their vintage, being at times capable – as Antoine Kreydenweiss had remarked of his 2008s – of projecting a sense of their sites without obviously revealing their varietal identity. I did not taste several slowly-evolving 2009s, including a Clos Rebberg Pinot Gris that was still fermenting when I visited last November.No current U.S. importer.
