Does Tabasco Sauce go bad (EVER)?

Ive looked at some of the answers on yahoo and none of them satisfy me. I have 3 bottles of 1/8th ounce unopened ANCIENT Tabasco Sauce and when i say ancient these are army issue with rations from like 20 years ago. my dad was in the military and these are from the early 90s, and i wouldn't doubt it if these were sitting in a warehouse for another 10 years before that, possibly 3 decades old. i'm talking the older than dirt old.
