A visit to Napa or Sonoma is not complete without a stop at Domaine Carneros. Located in the Carneros AVA, between Napa and Sonoma counties, the eye-catching Domaine Carneros sits on a hill in its grandiosity. Owned by the Tattinger family, the magnificent château was inspired by the 18^th century Château de la Marquetterie, the Taittinger family residence in the Champagne region. To get to the château, you walk up a large set of stairs. At the top, you will be greeted and seated at a table along the outdoor terrace where you can enjoy a flight of wine or a glass of wine. It is a relaxing, elegant wine tasting experience. But, Domaine Carneros has now taken it to the next level with the Jardin d'Hiver, a garden conservatory.
