Yeah, as long as I like my result and you like yours and everybody else likes theirs, we're all happy vapers.
Right, in the here and now, where if nic gets too far oxidized, we can just buy more, and a year's supply of nic costs less than what many of us would spend on a carton of smokes in the past.
But what happens if/when the FDA decides that the era of free-flowing nic is over? At that point, we become dependent on whatever we've got in our stockpiles, and the question this thread attempts to answer is: Does it really make a difference how you store it?
So far the answer seems to be rather unequivocal: Colder is better. The question of plastic vs. glass seems to be less obvious, at least when the plastic is PET.
I think this information is may be useful even for those who do like their nic somewhat oxidized, because I suspect there's a point where you might decide: "Ick, this is too far gone". So better to do what you can to keep it fresh until you're somewhat close to using it. At that time you can always oxidize it to the point that you like it best, but I don't think there's any practical way to revive it once it's gone too far.
