Open Cellar Days Ruwer

The Open Cellar Days are one of the central wine events in the Ruwer Region – the small but exceptionally distinctive valley for Riesling, which flows into the Moselle near Trier. From May 14th to 17th, 2026, vintners in the towns of Waldrach, Kasel, and Mertesdorf will open their cellars and tasting rooms to visitors from the region, from Trier, from Luxembourg, and for wine tourists from all over Germany.

The Ruwer-Riesling e.V. association bundles the activities of the local wineries and coordinates the event. Both well-known, internationally renowned houses – which have shaped the region's reputation – and smaller family businesses, whose wines are often hard to find outside the region, are involved. This mix is one of the attractions of the event: over a weekend, you can taste top Rieslings from the vineyards Karthäuserhofberg, Maximin Grünhäuser Abtsberg, Kaseler Nies'chen, or Waldracher Sonnenberg in comparison.

With around 200 hectares of vineyards, the Ruwer has a significantly smaller area than the Middle or Lower Moselle, but it has developed a distinctive style: the Devonian slate soils, combined with the cool locations, produce particularly fine, nuanced, and long-lasting Rieslings. Dry, off-dry, and noble-sweet styles are all produced.

In 2026, the Open Cellar Days will take place concurrently with the wine hike 'Wein im Weinberg' (May 14th), also organized by the association – combining both offers an experience of the Ruwer Valley over a long weekend, both in the cellars and on the steep slopes. Exact opening hours for individual wineries and the complete list of participants will be published on ruwer-riesling.de.
