OK. This source IS actually known for bad handling, now that you mention it (bastards), but this didn't seem like oxidation, and hops should fade if anything after some storage abuse.
Last time I had Stone's IPA was on tap a few years ago, though... and it wasn't as imbalanced as this. Maybe you've got me, maybe the hops flavors turned ugly instead of just going weak. It smelled like pineapple juice filtered through a pound of Northern Brewer.*
(*Actually I take it back, that sounds kind of good.)
I think Stones ipa is at like 60 ibus (i could be wrong here) which as you pointed out in this day and age of breweries trying to pack in as many hops as possible really isnt that high for an ipa. I see nothing wrong with saying a beer from a commercial brewery sucks we pay the exorbitant prices they are charging and should be able to expect the beer to live up to the level of those prices.
