Napa is made up of two main roads, Rt 29 and the Silverado Trail, and a series of cross roads connecting the two highways. There are wineries all along the two main roads as well as the cross roads. You can't throw a stone without hitting a winery in Napa. Therefore, many people head to Napa without a plan ... and that kinda works ... kinda. You will drive by countless wineries with a sign at the driveway that says "Tasting 10-4". You will also drive by wineries that are gated or have a sign that says, "By Appointment Only". No plan ... no problem. There will be plenty of "stop in" wineries and you won't miss out on wine tasting. But ... you may miss out on some of the more special wineries. Wineries that are off the beaten path and not directly visible from the highway. If you have the time ... or make the time ... spend some time planning your trip. It's easy find wineries like Robert Mondavi or Beringer Vineyards, but it's going to take a little effort to find wineries like Prager Port or Andretti ... and they are well worth the effort. One fun way to get ideas is to ask other wineries. If you call a winery to make an appointment ask that person what wineries they like ... and then research the names they give you to see if it is to your liking. If you want our help, feel free to send us an information request. We are happy to provide you with no-cost feedback on any winery in the valley that we have visited, and we have visited a lot! Happy Tasting!
