Ross and I can only describe Swanson Vineyards as a very unique experience. It has a great, Parisian flea market feel to the Sip Shoppe (the informal tasting room that doesn't require reservations). There is a tasting menu with kitchy food pairings, that range from potato chips and caviar to custom-wrapped Vosges chocolate.
The marketing for all of their products is very clever and even though we weren't overwhelmed by the taste of their wines, we really enjoyed the experience over all. (http://www.swansonvineyards.com/)
