After pouring myself an IPA from the keg, I found its flavor had changed considerably from last week. It was more bitter, almost harsh, and the wonderful grapefruit/citrus aroma from the late addition hops was almost non-existent.
I kegged this beer about two weeks ago... last week it was fine, but a little under-carbonated. I turned the regulator to about 10 psi to up the carbonation a little under a week ago. Could this be the cause?
The amount of carbonation is a matter of personal preference...I think that a lower level of carbonation brings out flavors more, and a higher level can accentuate harsher notes and hide the more subtle notes (serving it too cold can also do that).
Leave it alone for another week or two and you may like the result better taste-wise as the harshness smooths out a bit. It's not too late for aroma either... I age my IPAs much longer because I like them better that way (personal taste), but even so, my practice in recent years has been to not dry hop the beer until a few weeks before I start pouring it. The result is the clean but still quite intense bitterness that I like, and a nicely enticing aroma.
