Ok or too old?

[PinotEnvy]

I was looking in my basement to see what needs to be consumed sooner rather than later and found two bottles that I am wondering I let them sit too long. Both are 2002 whites. The first one is Tin Roof Sauvignon Blanc and the second is Big House White. Have they fallen off a cliff yet or do they just need to be opened right away? I kept them in the basement of my house in a closet under the stairs, so they have been in a cool, dark area and they are screw top caps.

Thanks.
