7PSI for serving (assuming high 30's serving temp) is a bit low in carbonation IMO for American IPA.  You do need some signficant carb to push out those hop aromas in your glass. i try to carb and serve at 11-13PSI at 38 degrees.

what are the actual hop stand, 15min and dryhop amounts?  Some people's idea of 'big' is pretty weak from what i've seen.

Interesting. I find lower end carbonation lends better aroma for me. High Co2 lends to a weird harshness in aroma and flavor.

I also agree with the 02 comments. Seems like even low levels of oxidation has a detrimental affect on hop flavor and aroma..

Another good suggestion.

I agree with you - high carbonation does lend a metallicy 'weird' aroma and bite in the flavor, but to get that its usually 15+PSI at 38 - 11-13 seems just the right balance for my tastes.

CO2 dissolves as carbonic acid, so it would make sense that more carbonation = more carbonic acid = more acidic flavor, right? Acidity could affect the aroma too I imagine.
