CO2 Purged PET Bottle or Vacuum Sealed Ball Jar for Hop Storage?

[geoffm33]

I have a stainless carbonator cap and some amber PET bottles. I could fill the PET bottle with bulk hops, attach the cap and purge the CO2. Downside is I'd have to swap out the cap for a regular bottle cap, potentially letting in some oxygen.

(fast forward to 2 minutes, 6 seconds):

OR, I could store the bulk hops in a ball jar and use the FoodSaver Vacuum Sealer and Cap as seen here:

If I stored both in the freezer, which would be the most effective method?

Note: I know I can use vacuum sealed bags that will remove almost all oxygen; and from what I have read that is the most preferred method.

For pellet hops, the mason jar vacuum sealer has been what I've used for the last 7-8 years and it is a great method!

What I've thought about doing is combining them both... Purge the mason jar (or bag) with CO2, then vacuum seal with the Foodsaver.

I've used PET bottles for years. Drill the cap, insert tire stem, fill and purge a couple of times with CO2 and toss into the freezer. It will literally keep hops fresh indefinitely. Or long enough, anyway.
