Sonoma County



  • a county in California that, with its neighbor Napa Valley, has helped to improve the quality and production of wine in California. The county has a range of climatic conditions enabling its more than 190 wineries to grow nearly every grape variety found in California. It is here that Count Agoston Haraszthy founded Buena Vista Winery and planted most of the 100,000 cuttings he brought from Europe.
