The G.H. von Mumm estate was launched in 1811, when Gottlieb Mumm presciently purchased the entire harvest of Schloss Johannisberg in what turned out to be one of the greatest European vintages of the early 19th Century. Two hundred years later, the estate consists of 161 acres of vines in 16 prime sites in the Rheingau, 85 percent of the acreage devoted to riesling. If the nomenclature “G.H.” and “Mumm” look familiar, Gottlieb and his two brothers and two other partners founded a little company in Champagne in 1827 that would become G.H. Mumm, named after Gottlieb’s son and famous for the unmistakeable diagonal red stripe; the Champagne house has been owned since 2005 by Pernod Ricard, taken in its acquisition of Allied-Domecq. The Mumm family has not owned the German estate since 1918.

But enough history! Our concern today is with the Wine of the Week, the G.H. von Mumm 50 degree Riesling Trocken 2011, Rheingau, produced under the watchful eye of present estate director Christian Witte. “Trocken” indicates a dry wine, and while even some German wines so designated can taste a little sweet, at least at the first sips, this example is the true bone-dry, limestone-dry, flint-dry. The wine is titled in honor of the 50th parallel that runs right through the vineyards of the Rheingau. Ephemeral elements of lime peel and grapefruit and elusive touches of lychee and jasmine characterize a bouquet that teems with limestone-like mineral qualities that go on to dominate the flavors of spicy and slightly roasted stone-fruit — peaches and yellow plums –and lend the wine a scintillating and steely sheen, all abetted by whiplash acidity of crystalline intensity. Yes, you feel the vibrancy and resonance all the way down through the somewhat austere but deeply refreshing finish. Now don’t mistake the G.H. von Mumm 50 degree Riesling Trocken 2011 for a multi-layered, nuance-filled wine; this is an entry-level riesling that displays all the necessary qualities in fairly simple direct and tasty form. We drank this one night with seared swordfish, covered with cracked black pepper and chile maresh, and it was terrific. 12 percent alcohol. Very Good+. About $13, representing Great Value.
