I recently purchased a large amount of hops via the internet. I have received them and have since realized my freezer doesn't have enough room, unless I piss off the woman by getting rid of something unimportant like food. So, I have 2 lbs of hops in sealed barrier bags that won't fit in my freezer. They are in sealed barrier bags, vacuum packed, and no worries about light. Will they keep in my cool garage? (average around 45-50*) Do they have to be frozen, in order to preserve freshness? I have not opened them and won't until I use them.
