Freezer. Vacuum packed. If you don’t have a vacuum packer, use a ziploc and get all of the air out that you can. Use within a couple months (or a little more) if you use the ziploc.
I vacuum seal mine and store in the freezer. If you’re going to use them soon, the fridge would be ok too, just try to get them as airtight as you can.
Vacuum seal is where I want to go. Doing the Ziplock sealing has to go the way of the dinosaurs. Are the regular vacuum seal bags the way to go or are the mylar foil bags preferred?
The foil doesn’t just block the light, it provides an impervious oxygen barrier. If I had foil bags for my vacuum sealer, I’d use them for long-term storage.
He said “oxygen.” When you have liquid in the PET bottle you can squeeze all the air out before capping it with the carbonator, then add CO2, but with hops, I don’t think you can do that, so there will be some O2 in there, but very little.
I have always assumed that the idea is to fill the container with co2, wait a bit for things to settle down in there and then purge through a top opening which should get most of the o2 out as it will have migrated to the top portion of the container. still some o2 but a lot less
