As autumn gives way to winter, slip away to this signature event, presented at the Ahwahnee in incomparable Yosemite Valley. Leading winemakers celebrate the fall harvest by pouring their prized vintages, and sharing their insights on winemaking trends at exclusive seminars—a don’t-miss experience for serious winophiles (sign up in advance on the website). There’s also an intimate reception to mingle with winemakers and pick up more tips (and sample more wines, of course). The crowning event is a five-course gala dinner, with dishes carefully paired with often rare or limited-release vintages shared by the participating wineries. Sign up early—this event typically sells out.
