Would it be effective to dry hop a beer that has been kegged and carbonated? More specifically, can I open the keg and drop in some dry hops for a week even after I have carbonated the beer?
If it's feasible, what temperature should I dry hop at?
I brewed and kegged a blonde ale which I was hoping would have a noticeable hop aroma. The results are only so-so. It could be that Calypso hops don't stand out as noticeably when used for aroma, or that the honey malt aroma is overpowering the hops. Or both.
The primary concern I see is that carbonation in the beer would just drive off any dry hop aroma I add to the keg, leaving it at best in the head space. I could try to de-gas the beer (I'll have to open the keg anyway) first, but I was hoping to serve this beer at an event in one week.
I've also considered a Randall, but I don't have any experience there and am concerned it would give more hop character than I'm aiming for.
