Autumn is just now beginning to cast its spell on the Texas Hill Country, with burst of burnt orange and gold scattered among the evergreens. Cruising down Highway 290, also known as the Texas Wine Trail, on a busy Saturday afternoon I encountered party buses and limousines full of eager wine enthusiasts being ferried to their next tasting. With five million annual visitors, the Texas Hill Country wine region is the second most popular wine tasting destination in the United States, Napa Valley being the first. There are 52 wineries in the region, which stretches from Austin to Fredericksburg and Lampasas to New Braunfels. On this day, I visited two wineries each offering its visitors a distinctive tasting experience.
