From a plot in the Falkenlay that could not be harvested until November – long after his other vineyards – Busch’s 2005 Pundericher Marienburg Riesling Spatlese Raffes displays fascinatingly complex, pungent aromatics: lemon and grapefruit zest. yellow plum, gooseberry, wood smoke, yeast, and crushed stone. This hits the palate with almost smarting intensity, yet for all of its suggestions of sur-maturite and what Busch reports was an achingly slow fermentation, it’s admirably clear, bright, and much less creamy than most of its siblings. In a finish marked by decisive stoniness, one reaps the consequences of 14.8% alcohol in heat. I would not bet on this wine’s future, still, it would be fascinating to return to over the next couple of years, perhaps to reassess, and meantime to consider its strength when matching with foods. Clemens Busch farms the steep slopes of the once-famous Pundericher Marienburg on the Lower Mosel entirely organically, which make him unique in the region and a source of wonder for his fellow vintners. Most of his top wines are labeled with their old pre-1971 site names. (Increasingly many growers are managing to get away with this.) Busch has been bottling nobly sweet Riesling since 1999, but never before – he hastens to inform me – in quantities remotely like those that nature imposed on him in 2006: Nine Auslesen, three Beerenauslesen, and a T.B.A.! Like Reinhard Lowenstein (and in a similar style), Busch is best-known inside Germany for his dry (or near-dry) single-site wines, which are not released for more than a year after harvest. (In fact, most of the 2006s had not finished fermenting yet when I visited last summer.)Mosel Wine Merchant selections (various importers), Trier, Gemany; fax 011 49 (0)651-14551 39; also imported by by Ewald Moseler Selections, Portland OR; tel. 888-274-4312
