single vineyard in the municipality of Erden (Bernkastel area) in the German Moselle wine-growing region. Centuries ago, the stone steps that gave the site its name were built to provide better access, or access at all, to the vine rows in the steep terraces for the laborious vineyard work. Wine was already cultivated here in Roman times, as evidenced by an ancient wine press that was found and partially excavated in the middle of the vineyard in 1998. The masonry structure measuring 10 by 14 metres with several chambers dates back to the second century and is thus the oldest known Roman wine press north of the Alps.
The south-facing vineyards at an altitude of 120 to 220 metres above sea level with a slope of 50 to 65% cover 37 hectares of vines on blue-grey Devonian slate weathered soils with a very high rock content. The Riesling variety is the main variety cultivated here. During the land consolidation in 1971, the formerly independent 0.5 hectare single vineyard Herzlay was incorporated into the Treppchen site. In 2015, it was registered as a cadastral site under the name Herzlei. It is solely owned by the Dr. Hermann winery. Shares in the Treppchen vineyard are held, for example, by the Berres, Bischöfliche Weingüter Trier, Dr . Hermann, Dr. Loosen, Dr. Pauly-Bergweiler, Erbes Karl, Joh. Jos. Christoffel Erben, Jos. Christoffel jr, Kees-Kieren, Kiebel Benedikt, Lotz Klaus, Max Ferd. Richter, Molitor, Mönchhof Robert Eymael, Roth Andreas, S. A. Prüm, Schmitges, Schwaab Albert and St. Anna vineyards. There are also other single vineyard sites called Treppchen in the Moselle communities of Piesport and Treis.
