First time time brewer here, with a couple of questions about dry hopping. I've got a partial mash cascade pale ale in the secondary, the nose is wonderful, but haven't sampled it as of yet. 1. Would you sample before dry hopping. 2. Would you go with more cascade, or use centiennial (i have both on hand), and 3. When you use pellet hops do you bag them or just dump them in the carboy? Any help would be appreciated.
