I think it has changed over the years. Several years ago, just for that one season, it was way hoppier than the usual Celebration. I think maybe they borrowed Sam Calagione's Randal to brew it with that year. I thought it was their best vintage yet, but apparently not everyone agreed. Several people I spoke to about it didn't like it being that hoppy. I sure did though.
Celebration season is my favorite time of the year. I'm not a fan of the spiced and fruited holiday offerings, but the big winter warmers are always a treat.
