Daniel Vollenweider, who is actually Swiss rather than German, launched this small but perfectly formed domaine in 1999 when he bought a hectare of vineyard in Goldgrube. Fifteen years later and the domaine is not much bigger in terms of vineyards, although its reputation as a source of great Riesling has grown substantially. The domaine is based in Traben-Trarbach, a charming old trading town in the northern part of the Middle Mosel. Goldgrube lies on the bend of the river just downstream opposite the village of Wolf, to which it is attached, and forms the majority of the domaine. Daniel is understandably excited to have found such a site as it not just well located but is planted with old, ungrafted vines. The soil in the Goldgrube is made up of grey and reddish grey slate and within the vineyard there is a sweet spot called Reiler, which Daniel harvests and treats separately. These are very fine wines.
