Schloss Johannisberg
The origins of this grand wine estate, high in the hills above (and slightly west of) Oestrich-Winkel, date from 1100, when Benedictine monks built a monastery and planted vines on the slopes below. The striking early-18th-century palace is closed to the public, but follow signs for the Weinprobierstand (wine tasting stand), where you can sample the local produce on a scenic terrace overlooking the vineyards. On the way, you'll pass by the beautiful, 12th-century parish church, notable for its suspended red cross. Elsewhere around the complex, you'll find a wine shop, which also offers the estate's gin, as well as Schlossschänke restaurant.
\nBetween April and October, you can book a guided cellar tour and wine tasting (in German only), or throughout the year you can opt for a pricier, exclusive individual/group wine tasting (English option). Schloss Johannisberg is a 10-minute drive or 45-minute hike from the center of Oestrich-Winkel.
