I have just been to pick up some grain and hops for the next few brews. I will be brewing tomorrow and sunday, the hops left from ag1 were sealed back up and put in the freezer. the new hops are still sealed should I put them in the freezer now or leave until after I have opened them up? when brewing and using a pack that's in the freezer how long before should they be took out to get to room temp or can they come out when needed and put in straight from the freezer? thanks
