Firstly if the words of his 'Bobness' are your thing then the Parker review that Majestic use in this wines description is from the 2006 vintage, not the 2008 (which incidentally he scores higher at 93 points and calls 'one of the greatest Napanooks made').
This is a very well crafted Napa Valley Cab, at a very un-Napa-like price. Ruby red in the glass, with a fruity nose. The wine is smooth and supple, with soft tannins and a long finish. Delicious stuff.
