I bottled mine to let them sit for awhile and let some of the flavors blend together a little better, I also brewed this in July and wanted to save it until winter time and not take over one of my kegs.
I was very impressed with this recipe last year. I don't know that my effort was a great clone but it definitely strongly resembled Christmas Ale. One thing to keep in mind is Great Lakes pumps this stuff out like crazy and the flavor is very different when it's fresh. As it ages the spices mellow out significantly. I always keep a six pack of Great Lakes for Christmas in July and it's nearly a different beer after aging for 6+ months. This will happen with your batch too. You might even notice a difference between a brand new batch and a batch that is only a few weeks older.
