I had the time periods a little wrong. The pale ale is around 8 weeks right now and the hop flavor probably started falling off around 6 weeks. The IPA is also around 8 weeks right now and the flavor is just starting to change.
Citra Pale Ale (morebeer kit however it was more concentrated because I used 4 gallons instead of 5) http://hopville.com/recipe/1305660/a...-pale-ale-2012
The pale ale went from amazing to average and the IPA went from mindblowing to good.
Another detail... I pitched the IPA onto the yeast cake from the pale ale. I doubt there is some microbe in there that is causing both to age poorly because they seemed so good/normal.
Also, looking at my notes closer I guess the IPA started fermentation a little warmer than I thought it had. ~72F which is not ideal. Some day I'm gonna get a fermentation chamber...
