The oldest bottle of wine in my house is NO MORE! I am drinking a 2005 Ravenswood Vintner's Blend Cab Sauv. This is about the last of my experiment on aging cheap wine. This was about an $8 bottle of wine when I bought it approx. 8 years ago. It has held up okay, although it is clearly past its prime. Upon opening, it seemed a bit tight and a bit oxidized. As it has opened up, it has smoothed out a lot; I get a pleasant, mildly fruity nose, a mild, mellow mid-palate, and now getting some cherry on the finish.
I predict that by tomorrow (if any is left) it will be totally shot (oxidized). I did give it a squirt of k-meta solution to help it fight off the O2 poison for the night.
