Many have believed that most of the world's well-renowned wines come from Europe -- many of them being either Bordeaux or Burgundy. But, Opus One's Cabernet Sauvignon does stand out as the "American Royalty". It comes at the top of the list of wineries highly recommended by my friend.
The price of the tasting does reflect the "Royal" status of this winery. $30 for a single tasting. And, reservation is required.
I believe that three types of people should definitely pay a visit to Opus One
1) For those who are truly into wines, yes, Opus One cab is rather phenomenal.
2) For those who want to progress from a "wine-snob-in-training" to a "full-fledged-wine-snob", this is definitely the first place to visit in Napa. I have to admit that I belong to this category.
3) Finally, for those who have no idea of wine tasting but can do an amazing job of pretending and appreciate the architecture(just like my mom, ha, ha, ha....), this is simply a quiet and beautiful place walk around and enjoy the view of the vineyard.
