While I am not certain, I was under the impression that it "keeps" the same as regular nic-liquid. As you know--air, light, fluctuating temperatures (in extremes) are the enemy of long-term storage of nic liquid, so I gather it's no different with WTA.
I prefer glass for all medium to long term storage (amber is best, but I have a thing for blue cobalt).
I am moving soon and am getting a small apartment fridge for the basement (to be set at about 55 degrees for long term storage of premixed liquids..unless I find out there is a better way/temp).
Those used to be very famous energy hogs -- I think because of sloppily built door seals. I guess that might have changed. Time to go to Consumer Reports? Or somewhere else? I know that the original very-energy-efficient fridges were created so that third-world medical missions could keep insulin cool with a solar-charged battery...............
However, if anybody has tested 'keeping' WTA, I'd like to hear about it. I have to say that per my very limited college chemistry, it is by no means guaranteed that one organic chemical will 'keep' the same as a different one. Unless there is some property of the 'family' that makes it like that. (i.e. alkaloids in general or something like that.)
