Alexander Valley Vineyards
Occupying the 1840s homestead of Cyrus Alexander, the valley’s namesake, this winery known for the widely distributed Sin Zin produces wines from Chardonnay, Sauvignon Blanc, Cabernet Franc, Merlot, and a few more grapes. Tastings are old-Sonoma low-key; book Experience Cabernet Sauvignon to sample the Bordeaux-style blend Cyrus and other Cabs. Twice-daily free tours pass by the production facility and through caves dug deep into a nearby hillside. Daily vineyard hikes focusing on the land and the winery's history conclude with a box lunch and tasting.
