Here are my recommendations for your trip to San Francisco Bay Area’s Wine Country.
Mumm Napa – the US outlet of the French champagne maker. Has “champagne” tastings, a great tour, nice surroundings and sun decks for relaxing on.
Kaz – small, family run winery. Mainly selling reds, you can “bottle your own” which is fun.
Hop Kiln – bigger but still local-ish winery. Out of the way country setting. Fruity whites.
Casa Nuestra – another small, local family run winery. Whites and reds are both good.
Gott’s, St Helena – old fashioned burgers and shakes. They have locations in Napa county and SF. This is the oldest one. All are recommended.
Morimoto Napa – Japanese restaurant owned by a US TV chef. It has a chic calming atmosphere if you get a seat away from the bar.
Sonoma State Historic Park – historic buildings in Sonoma. A little quaint with the usual themed guides but nice for a quick visit to get a feel for the old country.
As you travel to/from San Francisco over the Golden Gate bridge I recommend a few stops.
Fish, Sausalito – great harbour side fish restaurant en route to/from Muir Woods/Sonoma in Sausalito. Outside seats are best so bring a jumper if you are heading there in the evening.
