Sure, that's why we repeat the experiment regularly (though less formally than we used to). In fact, we just did it a few weeks ago with a friend who is a really hard-core wine snob. He has a 10,000 bottle collection in off-site temperature controlled storage. And he's not just a rich asshole showing off his wealth. He's upper-middle class and really passionate and knowledgeable about wine, as is his wife. Both of them rated the Barefoot cab very highly. No Silver Oak in the lineup this time, but some very comparable bottles, like a Franciscan and a Veeder Reserve, alongside a few other varietals (we were actually trying to see if we could pick out varietals blind). The Barefoot didn't come out on top, but it made a very respectable showing. One of the things we rated the wines on was, "How much would you guess this wine sells for?" My friend gave the Barefoot a $50 rating, and his wife said $130.
