On the Winery Experience in Napa Valley

What makes a good winery experience? Although every winery is different, some common features that stand out for me are a beautiful setting, attentive staff, tasting room managers who share their knowledge of the wine while they pour it, and, above all, good wine. I leave a good winery reluctantly, promising myself to return on a leisurely afternoon when I can relax with their great wine and learn more about the winery.
