The Schwarzwald region, despite the stereotypical Bavarian love affair with beer, is actually known for its time-honored and capable weingarters (wine-makers), at least 20 of which produce a variety of wines from very near the city of Stuttgart. Connoisseurs among us already know of the international reputation of German wines, making this quite an intriguing addition to the itinerary, especially if you're looking to taste a locally famous red known as Trollinger.
Beginning at the train station in Obertürkheim, you'll have the opportunity to walk from winery to winery or by means of public transportation through 12 km (about 7.5 miles) of luscious vineyard landscapes. Most wineries will have guided tours and samples of various wine types, most of them on the sweeter end. Keep in mind that the best time to visit is not in the touristy summer months, but any time from fall to spring - popular festivals like the Fellbach Autumn Festival do an excellent job highlighting these local wines.
