We made an interesting discovery about wineries. The ones in the Napa Valley are MUCH more expensive than the ones in Sonoma. They seem to think that people visit for the experience rather than to stock up with wine. We were surprised by the cost, which was often quite similar to what we expected to pay in restaurants - but we thought that it must be right as it was consistent wherever we visited. Then we visited a vineyard near Sonoma and discovered that the prices were less than half ! It is obviously a Napa Valley cartel, designed to keep their bottle price high. As far as we are concerned, the wine in Sonoma was just as excellent (I can hear Tiggy and Sergio groaning when they think of the wine we used to be happy with, before they both got us in hand). As we will not be bringing any back to London, you will have to take our word for it.
