I picked up a few Cabs from Costco the other day and boy oh boy, they are fantastic! Mondavi's Napa Valley 2005, Rodney Strong 2005, and Beringer Knight's Valley also 2005.
2005 must be a good year. Seems like every Cabernet coming out of Napa Valley is really good. Time to buy a few cases!
A few days ago I picked up Beringer Founder's Estate Cabernet Sauvignon 2005 which I thought was really solid especially for the price. If you drink wine on a daily basis as I do this is a great choice that won't destroy your wallet at around $10 a bottle.
Another delicious value play worth mentioning that I will buy again without a thought: Hayman and Hill Napa Valley Cabernet Sauvignon Reserve 2006 at $13 a bottle.
