OK so now I am curious about OP's experiences.
1) My juices invariably darken, presumably basic oxidation, over time, although in many cases the flavor improves, not always, so I don't absolutely agree with the seeming rule of thumb that "tobaccos must be steeped".
(Incidentally, it is trivial but bugs the .... outta me for some reason - if you are mixing liquids there is no such thing as "steeping", which by definition is a process where liquid is left in contact with solid matter. You steep tea leaves, you may steep tobacco leaf if you are using it, but you ain't steeping no juice, there ain't no such thing, period, it's aging not steeping. But call it what you like, and I digress ....)
2) Out of curiosity I made some various flavor bases up with no nicotine, and as long as they do not have vanillin in them, at least so far - a couple of weeks - no color change.
3) I have had some batches of nic base darken gradually, but others have stayed clear a long time and I keep it all in the freezer now. Even juices with nicotine base that stayed clear at RT darkened in less than two weeks.
Emprically, I would hypothesize that (in the absence of something like vanillin, which itself if fact darkens much less rapidly even when highly diluted than nic juices also) it is the nicotine in conjunction with flavorings and dilution and oxidation that result in darkening uponsteeping *aging*.
I pulled out some old vendor juices which are at 24mg Nicotine and after months, having been opened and in identical containers and storage as my DIY juices, they have not (appreciably) darkened upon lengthysteeping *aging*.
Which leads finally to my question:
In light of the fact I have an almost dead bottle of nic base that has been around for months also at RT and is still clear, presumably at least some batches of nic base I have used have been of comparable quality to any out there, yet my juices stilll darkened.
What do "they" do differently I wonder? Maybe adding a little BHT and not telling anyone or ....?
