The 2006 vintage for Napa Valley Cabernet has been all over the charts. For every charming, sumptuous wine there's another that's terribly hard and tannic. This flight of mountain- and hillside-grown Cabernets impressed me for its uniformly high level of quality. Make no mistake—these are firm, tight, structured young wines, with no baby fat showing. But they're also very complex and balanced, offering ripe flavors (and they're devoid of the overly dry and tannic character that too many 2006s have shown). Scores and tasting notes for these 16 wines follow.
