I am supposed to take some visitors from Vietnam to Napa Valley tomorrow.
We will be starting at Domaine Carneros. My wife told me these visitors know
nothing about wine, and I am supposed to pick the wineries for the
tourist experience (tour, etc) not for the wine. So I am wondering what
are the Napa wineries that have the best tours right now? It has been
a while since I have tried to be a tourist in Napa. The tours I remember
from many years ago are: Robert Mondavi, Domaine Chandon, Beringer
and Sterling Vineyards. Are there any newer fun tours you could recommend?
