Good beer, just not great. Has a nice balance of maltiness and bitterness, but seems to be missing something in the hop flavor and aroma department. It has the Chinook flavor coming through and a little bit of citrus, but it's just not quite there for me. Very drinkable though, but I think the Celebration Ale is better.
Where are you coming up with Chinook flavor? According to the SN website, there is no Chinook.
I was surprised to see SN was using Magnum for dry hopping. I'd never considered using Magnum in that application myself.
