Hi David! We actually do not have a permit to allow picnicking. Sorry we can't accommodate! The Napa Valley Vintners website provides a list of wineries that do allow picnicking: https://napavintners.com/wineries/wineries_picnic_areas.asp I hope this helps!
They have patio seating, and probably don't mind people bringing some snacks. However, there are not large picnic tables or grassy areas like you might see at other wineries.
Thanks! Your answer is awaiting moderation.
