I do think that age and proof of a bourbon can be far more revealing than varietal and origin of a wine. They could just give you the same information for a whiskey: "bourbon, USA," "single malt, Japan," etc.
This is the problem with revealing age and proof: as I said, the bottle that was the subject in your article is one whose identity one can be reasonably sure of from the information given. There are many others. If you were holding out hope that you were tasting some other wonderful 11+ year, 107 proof wheater that no one had heard of yet, I have to believe that you were guilty of willful suspension of disbelief - which, by the way, I think is FAR better than saying "OK, number 38 is the Pappy. It wins."
Also, I understand that you're not responsible for setting up the rules and only had to operate with the information given you, so doing your best to not decide which is which based on age and proof was likely the most impartial way for you to proceed.
