Ungstein's Terra Rossa Grosse Lage on Roman Ground

Weilberg

The Weilberg rises above the village of Ungstein, a district of Bad Dürkheim in the northern Pfalz, and it carries a claim few German sites can match. It is regarded as the nucleus of Palatinate viticulture, the place where Roman settlers established a winery roughly two thousand years ago and brought vines to the region. A reconstructed Roman winepress still stands at the site as a reminder of that continuity.

The Site

The Weilberg is a gently inclined slope rather than one of the steep faces associated with Germany's river valleys. It sits at roughly 140 to 170 metres above sea level, with gradients that run from around 5 up to about 20 percent. The exposure is south to south-southeast, giving the site steady sun through the growing season without the extreme pitch of a slate cliff. The classified area covers around 32 hectares, planted very largely to Riesling.

Red Earth

What sets the Weilberg apart is its soil. Across most of the Pfalz the ground is dominated by Buntsandstein, the coloured sandstone of the region. The Weilberg instead carries a clayey loam with a notable limestone content and a high proportion of fine earth, stained deep red by hematite (iron oxide, Fe2O3). Growers and the VDP describe it as Roterde, or red earth, and liken it to the Terra Rossa soils otherwise found around the Mediterranean, reading the colour as a sign of a generous mineral supply. At the core of the site lies a parcel of roughly one hectare where this red earth is at its most intense, long regarded as the heart of the Weilberg.

Classification

The Weilberg is classified as a VDP.GROSSE LAGE, the top tier of the VDP's four-level vineyard hierarchy and the German equivalent of a grand cru. A dry Riesling from the site, farmed to VDP standards, is bottled as Grosses Gewächs (GG).

The Wines

Weilberg Rieslings tend toward richness and spice rather than austerity, a character growers attribute to the warm red-earth clay. Weingut Pfeffingen, based in Bad Dürkheim and one of the site's leading names, describes its Weilberg GG through aromas of wild herbs, pineapple and sage with a note of white pepper, calling the wine fresh and mineral with a powerful, dense body built for ageing. Weingut Rings farms the site as well; a wein.plus assessment of its dry Weilberg GG found a firm, deep and completely dry wine with chalky, smoky and buttery traces and marked acidity. Oliver Zeter also bottles a Weilberg Riesling, from vines planted in 1982, fermented spontaneously in barrel and held on its lees into late summer.

Across producers the through-line is the red earth. These are wines with breadth, a savoury and spiced edge, and the mineral drive that limestone and iron lend to Riesling on one of the oldest cultivated slopes in Germany.
