Leoness Cellars
If the day gets one winery, make it this one. Leoness sits on the quieter De Portola wine trail with vineyard rows falling away below the terrace, and it does the two things a day-tripper needs from an anchor stop: a proper standard tasting ($35 at this check, with advance reservations recommended during busy periods) and a Friday-through-Sunday restaurant that makes lunch part of the same property. The last few months of reviews keep crediting the staff—hosted tastings that actually teach, servers who don't rush the flight.
