Ürzig & Erden: Ürziger Würzgarten and Erdener Vineyards

The villages of Ürzig and Erden occupy one of the most geologically distinctive stretches of the Middle Mosel. Where most of the Mosel Valley is defined by blue-grey Devonian slate, the bend at Ürzig exposes volcanic rhyolite nearly 300 million years old, the result of the Mosel cutting into the Wittlischer Senke depression along an ancient rift line. This makes Ürzig the only Mosel wine-growing village with volcanic rock outcrops, and Ürziger Würzgarten the only vineyard in the entire region where volcanic flow combines with Devonian slate and sandstone to produce blazing red, iron-rich soils. Erdener Treppchen, directly across the river, features red slate with iron oxide elements, while the tiny Erdener Prälat combines blue-grey slate with red iron oxide influences.

• Volcanic rhyolite in Würzgarten is approximately 300 million years old
• Ürzig sits on a rift line, the only such geology in the Mosel
• Erdener Treppchen: red slate with iron oxide; Erdener Prälat: blue-grey slate with red iron oxide
• Rocky volcanic soils allowed ungrafted Riesling vines to survive phylloxera in the 1860s

Both villages benefit from a classic Mosel cool climate with a long growing season, but Ürzig enjoys additional protection from western rain thanks to a barrier created by the Eifel highlands. The amphitheatre-shaped Würzgarten vineyard traps heat from the river below, complemented by approximately 1,400 hours of annual sunshine and July average temperatures around 18°C. Slopes reach gradients of 65 degrees or more, making mechanical cultivation impossible. Every harvest is carried out by hand, and the stone steps built into the vineyards centuries ago, the origin of the Treppchen name, remain the only practical way to navigate these precipitous sites.

• Ürzig sits in a rain shadow created by the Eifel highlands to the west
• Approximately 1,400 hours of annual sunshine; July average around 18°C
• Slopes exceed 65 degrees, requiring exclusive hand-harvesting
• Treppchen means 'little steps,' referring to the ancient stone stairways built into the vineyard

Riesling is the exclusive grape planted across the premium vineyards of Ürzig and Erden. Ürziger Würzgarten and Erdener Treppchen both hold Grosse Lage status under the VDP classification, the German equivalent of Grand Cru, with their dry wines released as Grosses Gewächs. Erdener Prälat, at approximately 2 hectares, is among the most prized sites in the entire Mosel Valley. It is harvested last each year and, due to its exceptional botrytis conditions, exclusively produces Auslese-level wines. Vines in both Würzgarten and Erdener Prälat include ungrafted examples up to 100 years old, a direct result of the rocky volcanic soils that prevented phylloxera from taking hold.

• Grosse Lage (Grand Cru) status under VDP for Würzgarten and Erdener Treppchen
• Grosses Gewächs designation applies to dry Rieslings from these sites
• Erdener Prälat: approximately 2 hectares, always harvested last, Auslese level only
• Ungrafted vines up to 100 years old survive due to volcanic rocky soil

Viticulture in Ürzig and Erden stretches back more than 2,000 years, with Roman-era evidence including an ancient wine press uncovered during excavation at Erdener Treppchen. Monastic production was established by 1177 when the Cistercian Abbey at Himmerod founded what is now Weingut Mönchhof, a property that has been in continuous wine production since the medieval period and in the Eymael family since 1804. The area survived phylloxera in the 1860s largely because of its rocky volcanic soils. Today, key producers include Weingut Joh. Jos. Christoffel Erben, Dr. Loosen (a VDP estate with Würzgarten holdings), Dr. Hermann, Karl Erbes Riesling Winery, and Weingut Merkelbach, all of which maintain traditional practices suited to these demanding steep-slope sites.

• Weingut Mönchhof founded as monastic vineyard in 1177; Eymael family ownership since 1804
• Rocky volcanic soils allowed the area to survive phylloxera in the 1860s
• Dr. Loosen is a VDP-classified estate with significant Ürziger Würzgarten holdings
