Hosting Wine party, HELP!

[deal]

The most recent red I purchased was Robert Mondavi Private Selection
Cabernet Sauvignon
California 2007 and I found it have an above average oak taste. And the last Washington State wine was a 2005 Columbia-Crest Merlot Cabernet and was disappointed because it said to have an "extended aging in small oak barrels." Maybe Im being too picky but I know there are unlimited amounts of flavors. I'll check out the Kendall-Jackson Reserve, thanks!
