I picked a bottle of the 2001 Mirassou California Cabernet Sauvignon on a whim this afternoon. It was about relatively inexpensive ($10), and I figured three and a half years would be enough time to mellow out any harsh edges. I've got to say that I didn't like this one. I could never find an exact percentage, but to be labeled as just a cab sav it has to at least 85% of that grape, and the rest can be whatever. This one obviously has a lot of merlot in it, but it sure tastes like a lot more than 15%.
Don't get me wrong, it's not a bad wine, I mean, the bottle disappeared over the course of a Yankee pot roast dinner. (I don't think it was the right wine for the meal--a fuller bodied, more tannic red would have been more appropriate.) It's really hard to explain, but this wine just acted weird on the tongue. It started out reasonable enough, but the finish was almost nonexistant. Not recommended.
