Vacuum sealing them seems like a good policy. Don't know about hops, but freezing is bad for coffee because the flavour oils will "evaporate" (sublime) in the cold. I keep dried hops in the freezer too (preferably well sealed).... have vacuum sealed them and stuck them in the freezer. We'll see how they go..!
How much hops did you use? I've just picked about a kilo of Fuggles and Goldings today.I have been looking for the same info with regards to freezing fresh hops and have come up with conflicting views. Some say it just don't work and then theres others that say it works fine and they keep theirs for 12 months in the freezer.
I have just picked a load of fresh fuggles this week and did a brew with them as never done a wet hop brew before and then picked another load and have vacuum sealed them and stuck them in the freezer. We'll see how they go..!
