Setting and Exposure
Felseneck faces due south, catching the warm midday sun across a steep slope while surrounding forest shelters it from cold downslope winds. Sources place the vineyard between roughly 220 and 310 metres of elevation, on gradients running from around 35 up to about 60 percent, with the steepest reaches reported by some accounts as high as 70 percent. Its position in a narrow, elevated side valley rather than on the main river makes it a cool, late-ripening site, and that slow ripening is central to the firm structure of its wines.
Geology
The rock here is unusual for the region. Rather than the single blue Devonian slate of the Mittelmosel, or the porphyry-dominated volcanic sites downstream at Schlossböckelheim, Felseneck rests on a stony, weathered conglomerate of the Upper Rotliegend (the local Wadern layers). Its main components are blue Devonian slate, basaltic volcanic rubble and white-grey quartzite, with porphyry noted in the VDP's own description. The result is a barren, quick-warming, stony-sandy ground that fuses slate and volcanic material in one formation. That combination is the source of the "fine, multi-layered minerality" that the site's growers and grosse-lage.de attribute to the wines.
The Wines
Felseneck is planted to Riesling, and Schäfer-Fröhlich draws an unusually complete range from it: a dry Grosses Gewächs alongside Kabinett, Spätlese, Spätlese Goldkapsel and Auslese in the fruity and noble-sweet styles. The estate's leading Rieslings are fermented spontaneously. The vines are old by the estate's own measure, averaging roughly 60 to 65 years, the highest average age of any Schäfer-Fröhlich holding, which feeds the concentration and depth the wines are known for.
Across styles, Felseneck is described as the firmest and most tightly built of Tim Fröhlich's dry sites, with a stony, mineral character and the acid backbone to hold in the cellar for many years. Tim Fröhlich won the 2009 Der Feinschmecker German Riesling Cup with a Felseneck Grosses Gewächs, an early signal of the standing the site now carries.
Holdings
The Felseneck monopoly covers roughly seven to eight hectares within a Schäfer-Fröhlich estate of around 20 to 24 hectares, the bulk of it Riesling. The family has grown wine in Bockenau since about 1800 and farms the site outright, which makes Felseneck the clearest single statement of the estate's style: cool-climate Nahe Riesling grown on slate and volcanic rock and built for age.
