Francis Ford Coppola Winery 

Hi there. There's a bus that you can take from San Francisco Airport to Sonoma County airport. Here's the link for the Sonoma County Airport Bus schedule. You will also find the ticket cost here. airportexpressinc.com/schedule.php. When you get to the Sonoma airport, it will be like 15 miles away to get to the winery. You can take a taxi or Uber. Unfortunately, there's no bus that will take you directly there. You need a reservation. If you don't drink, they have a lot of options for food and other non alcoholic drinks. There's also a swimming pool but you need a separate reservation. The museum is free. Good luck with the trip!
