Three of the most renowed wines in California are Far Niente, Cabernet S., Chateau Montelena, Cabernet S., and Opus One.
Far Niente and Chateau Montelena are Cabernet S., and Opus One is a Cabernet S., Cabernet Franc, Merlot and Malbec blend.
There is no comparison among the three wines, but there's one element they all share: a great winemaking process resulting in exceptional wines.
