I need suggestions for which wineries to visit for a very short trip to either Napa or Sonoma. We will most likely drive there one morning and head back to San Francisco early/late afternoon. It will be our first trip to a winery. I enjoy whites/sparkling wines and my husband enjoys red.
Any advice would be greatly appreciated. I have searched and searched the internet but there are so many choices and with little time to spend any advice would be great.
