Over Carbed Beer

I bottled my barrel aged imperial red about 3 weeks ago.  Just openned my first bottle.  It seems to be overcarbed.  Not even close to gushing or anything but its overcarbed for the style of beer.  What can I do?  I'm giving this beer away as a gift so I'd really like to fix this problem.  Would opening every bottle and letting them sit for a while and then recapping them do anything?  Open for suggestions.  Thanks!
