Weingut Sermann — Winery in Altenahr
It may not be on the list of the best-known wineries in the Ahr, but the quality is top-notch: a kind of hidden gem in the Ahr. A nice extra is that besides Spätburgunders they also make very good white Rieslings. It's on the other side of the Ahr valley from Bad Neuenahr, and they have one of the better restaurants in the area, called Thüres. Ideal for combining lunch with a tasting here!
