Barring that, using a resealable bag that you remove as much air as possible from will work well. You questions are good ones, unfortunately the effect of storage is somewhat variety dependent. Some hops store better than others, so there is no definative answer there. I will say that the effect is not broken into aroma, flavor or bittering either, seeing how its all based on the storage effect on the gland of the hop. Aroma, flavor and bittering all come from the same place, its the boil time that really determine what you are getting from the hops.
In general, there may be some statistics out there that give the degradation rate of each variety under certain storage conditions. I haven't seen a clear chart or table with that data though.
I have stored hops in the opened mylar bag I got them in wrapped in a sealed ziploc in the freezer for a couple years and not really noticed a huge change in bittering potential. The hops slowly loose their alpha potential with time. A month later you probably don't notice the change, a year later I think there is some great advice here but I listen to a lot of bodcasts and there is a particular Beersmith podcast called "hop chemistry" where James Altwies from Gorst Valley Hops gives some great info and mentions that they freeze their hops at an insanely low temp.
Most varieties will safely store frozen for up to a year if wrapped tightly with low oxygen content. Beyond one year you will likely begin to see some degradation.
According to the hops book from the great Brewing Elements series, if you store your hops pellets in the freezer in a vacuum bag, it should stay usable for up to three years in general. Loss of alpha acid will occur, but not too much. This is not true for fresh hops, though. I store my hops in a freezer at deg C and vacuum it always after use and am pretty content with it. The key factors here are oxygen and temperature. Sign up to join this community.

An HSI of 30 percent means that 6 months after harvest, the hops theoretically possesses 70 percent of its original bittering potential.
Hops should not be stored in the light, despite that attractively illuminated display at the homebrew supply shop. Light prematurely ages hops, just as it does people. Keep your hops in the dark to ensure quality. In fact, keeping hops in the freezer prolongs their life by four times or more.
Cheers, Tony. Dona nobis cervisiam! I wouldn't say indefinitely, but should last quite sometime, if stored properly. The problem is going to be trying to fight off freezer burn. I'd probably taste the hops before using to make sure. I buy hop pellets by the pound and store them in the freezer.
I put them into freezer bags and push out all the air. From what I've read they lose bitterness over time, but I haven't noticed. I should add that I've stored them for up to two years.
The cause of - and solution to - all of life's problems! Since I brew 10 gallon batches, I packaged the hops in oz. Very happy with the results.
