I had a friend of mine give me a few bags of hops to play with, he gave me some Liberty, Centennial and some Crystal. I was thinking about doing a Smash. I know the Liberty and Crystal are mainly aroma hops. I am also going to do an Amber Ale which I normally use Cascades on but since I have the Centennial I might use them instead for that. So I guess I am wondering if doing a smash with the other two would be worth while or if I should use the left over Centennial from the Amber for bittering and the others for aroma?
