Napa Valley is nice, but if you want some real romantic shyt, you go to Mendocino wine country in March during off season. It’s the most stereotypically beautiful small town costal California as it can get and all the wineries are empty.
If you go to Napa you can just go to Frog’s Leap or Duckhorn. I’m a member there. It’s nice. Wines are high quality. Their best wine vines burned down in 2017. Also a big secret that crackers won’t tell you is that most of the best vines at a lot of wineries actually burned away. And wine is grossly overpriced and they lie and their vines are young and they are running out of supply of their finest aged wines because they sold them to stay afloat.
