We’re headed up to Napa this weekend with a bunch of friends, and our plans have altered slightly. Sunday was to be a half day of tasting, but has opened up and the group wants to try a hand at tasting all day. We have afternoon plans for tastings in Carneros/Sonoma (Adastra and Sojourn). Are there any reputable places we can drop by on Sunday morning? I was going to take the group to Heitz to try the port because reservations are not required there. It may be too late in the game to try to make appointments.
