I want to dry hop a keg with a pale ale I recently brewed. The beer was brewed on 12/15, is currently in my primary, and is done fermenting. It will be served starting Thursday 1/22, and I absolutely expect it to be gone before the weekend is out. I have 2.5 ounces of Galaxy hops for the job, and I'm going to employ the weighted mesh bag with dental floss method. So here's my question. I plan on kegging it about 3 weeks before serving, so right around New Year's Day. I'm not worried about getting any "grassy" flavors as some worry about with extended dry-hopping, but I would like to serve the beer at the peak of that fresh hop flavor. I've heard anecdotal evidence that you've gotten all of the hop flavor you're going to muster after about 6-10 days, so would it behoove me to start carbing at serving temp, and then maybe 10 days before serving open the keg and add the hops, or are those 12 or so extra dys not really going to make a difference, and I should just go ahead and add the dry hops when I transfer from my primary?
