Walk in the door of this restored barn, and you'll be greeted with a sample of wine made in Pennsylvania's largest winery. Then take a self-guided or guided half-hour tour. In-depth winemaking tours are also offered Fridays at 3pm and Saturdays at 1pm. For $8, buy a glass and try a wide variety of regional wines. Check the website for classes and festivals. This is also a good place to start on the Brandywine Valley Wine Trail, a collection of area wineries and vineyards. Get a map at Chaddsford or go to www.bvwinetrail.com. (Bring your GPS; the map's just a guide.)
