Dry Creek and Alexander Valleys

On the west side of U.S. 101, Dry Creek Valley remains one of the least-developed appellations in Sonoma. Zinfandel grapes flourish on the benchlands, whereas the gravelly, well-drained soil of the valley floor is better known for chardonnay and, in the north, sauvignon blanc. The wineries in this region tend to be smaller, which makes them a good bet on summer weekends, when larger spots and those along the main thoroughfares fill up with tourists.
