Fodor's Expert Review Alexander Valley Vineyards

The 1840s homestead of Cyrus Alexander, for whom the valley is named, is the site of this winery known for Chardonnay, Merlot, Cabernet Sauvignon, and a trio of Zinfandels, most notably the widely distributed Sin Zin. Tastings here are low-key and breezy; opt for the reserve one to sample the single-vineyard Cabernet Sauvignon and the Bordeaux blend called Cyrus. Twice-daily free tours take in the winery and caves dug deep into a nearby hillside. Weather permitting, you can take an invigorating vineyard hike (book at least two days ahead) focusing on the land and the winery's history.
