I had the chance to taste the 2006 Alexander Valley Silver Oak Cabernet Sauvignon the other night in Baltimore; previously, I have tasted this wine in 2009. I was pleased by the wine but did not think that it demonstrated great value ($60ish retail, $26/glass at Vino Volo). The wine itself is very well balanced, with classic flavors of black and red currant, hints of dark cocoa, and fine dusty tannins that gave it good texture; however, the nose is a little hot (too much alcohol overwhelms the finer, subtler aromatics).
I have typically found Silver Oak to produce intermittently spectacular wine and most vintages rate good to decent in my book. My best experience was with a 15 year old 1994 Silver Oak Napa Valley Cabernet in 2009.
