I like to go to the smaller, more out of the way places when I am in the area, largely because I have already done "The Big Wine Tour" thing years ago, because I am usually passing through on other business, and because I like to smaller laid-back feel of Santa Ynez/SB (though that has definitely becoem more "Napa" in the last 20 years). I'd look through the list of wineries for places you've never heard of and give 'em a shot. Makes it more of an exploration, than a visit to the home office.

I like Cline Cellars... smaller, less pretense, a bit South of the Napa-Sonoma frenzy, not super touristy, decent Zins, nice staff, generous and off-list pours. Nice gardens.

I would NEVER go to Ravenswood again, though. Maybe a bad day, but hard to get to, packed with Zin fans, rude staff not being nice to Zin fans (plus they mainly buy grapes, so not much of a vineyard feel, but I knew that in advance.) I actually don't buy Ravenswood because of the horrible visit to their tasting room.
