I just finished off a bottle of 90 Minute IPA that had very little hop flavor and aroma. Maybe my palate has changed over the years, but I found it cloyingly sweet without a significant hop balance. The bottle was dated 6/7/2012, making the bottle around 3 months old. If you are paying a premium for a beer that doesn't age well, how old is too old for you to consider purchasing that particular beer?
