As you approach the upper end of Napa Valley, an alabaster-white monastery-like structure comes into view sitting atop a wooded knoll rising from the valley floor two miles south of Calistoga. This is Sterling Vineyards Winery, called the most spectacular winery in America when it was completed in 1973. It was the biggest new winegrowing venture in Napa County, with a six-million-dollar investment in the future of premium table wines.
