Hungry? If you're visiting between Mar and Nov check out the Seghesio Family Tables food & wine pairing! http://winerycritic.com/a-visit-to-seghesio-family-vineyards/
If you have a Visa Signature card, you may qualify for a free tasting; make sure you ask about it. Seriously though, buy a bottle and get a complimentary tasting; it's completely worth it.
