Each stop allowed us six to eight tastings of everything from fruity whites to painfully tannic reds (which I detest) to raspberry champagnes to weirdly sweet ports. R arranged for the local market to have lunch delivered at our second vintner, and we dined peacefully and happily in the shade of the trees, with magnificent views all around.
The last stop on our journey involved a woman who seemed to be hurrying us along, and I think that's the only place we didn't spend any of our hard-won cash, but as a group we did buy quite a bit of wine, and, for the most part, it was an extremely enjoyable experience.
California is weird, and beautiful, and unique, and spending a day with good friends and good wine is a pretty amazing thing. When you come to visit, we'll do this, I PROMISE!! :)
