Sonoma - best using Visa Signature

[krystle920]

We're planning to spend a day in Sonoma in September, and avail of the free tastings using our Visa Signature card. Although we're primarily red enthusiasts (cabs, pinots, but not so much red zins), we are open to any type of winery featuring really good wines. Question is - among the wineries listed in the link below, which do you highly recommend? We are driving from San Rafael for the day. Thanks!

Quivira is a favorite of mine from that list. Some friends who like big red Californian wines have said good things about Pedroncelli and Papapietro-Perry, but I've never done either.
