It was such a lovely place...
My wife and i went to this domaine in the napa area.
The place was really lovely and the quality of foods and drinks were really impressive. You have several options for the degustation : different kind of champagne with or without cheese and same things for wine.
We took the champagne because we're french and we wanted to taste the difference with the champagne we know. It was really exceptional. Then, we learned that the domain belongs to one of the most famous champagne brand in france : Taittinger.
Overall, it's a really good experience despite it's pretty expensive ( $14 for the champagne experience and then $14 for the cheese )
Also they offer free tour in their caves which was really interesting !!
