Twice as large as Napa in size, Sonoma County only makes about a half the amount of wine as her northeasterly neighbor. But Sonoma, with her size, is able to vouch for more diversity within her borders, including sub-AVAs that are climatically varied. The atmosphere of Sonoma is decidedly laid back and down home country style. But in wines, they are keeping up with the Joneses, or Napa-ites if you will. Grape varieties are more varied here, from Pinot Noir and Zinfandel to Cabernet Sauvignon and Chardonnay.
