If anyone is still paying attention to this thread, it is now 18 months from when I first laid down the MFS 100 mg VG in the amber glass bottles in my cold room, then moved them to the freezer, where they have been for over 12 months.
Zero change to the 100 mg VG. None. Still colorless, clear, no loss of nic, no sign of O2 reaction. The juice is just as fresh and excellent as the day I got it.
On the other hand, last Christmas I pulled out the Totally Wicked 36 mg PG unflavored I also stored in their original amber glass bottles (which also had euros, BTW). This juice is chinese made and the nic is lower quality, to the extent that common tobacco compounds from less than perfect extraction methods are listed as ingredients. This juice was no longer the slight yellow it started out as. It was deep orange, and had developed a strong tobacco taste. Actually was really tasty as a tobacco juice, but I can't do PG, so they were given to someone who recently started vaping as an Xmas present. Pg is still quite liquid in the freezer, so obviously something chemical had happened. Reaction with O2 in the PG? Dunno.
The Decadent Vapor 54 mg pharm-grade nic in PG, however, which was also stored in the freezer the whole time, was unchanged. So unless they got rid of dissolved O2 in their PG, which I doubt (would require vacuum pump), even though the PG was liquid, the cold had stopped the O2-nic reaction kinetics. Otherwise it would have yellowed the juice, if not deeper.
So its now clear (and colorless!) that high-grade nic in VG is stored extremely well in glass in the freezer. High-grade nic in PG should also store great this way. I say should because I only had one type of nic in PG (DV), but I have 3 different sources of nic in VG (Vermont Vapor, MFS, and now Box Elder). They are all doing just great in the cold!
I consider this experiment now complete, and I feel confident that this is indeed the best way to store unflavored nic liquid.
