All of my remaining long-term stash is NN Armor V1. I've had no complaints with it at after 5-6 years in the freezer. In fact one of the current set of samples is NN Armor V1 that I bought in 2014 and you can see it was perfectly free of color when I opened it last November. Of course the freezer samples still look just as good, and the refrigerator on nearly so, despite being re-bottled and thus no longer under argon.
All my other freezer samples also still look good, despite them not being under argon. So is argon necessary? Probably not, but it sure can't hurt either.
No, I don't titrate it. I take whiff when I open the bottle, and do a visual check of the color when I dump it into my clear mixing container. I do vape mostly (but not exclusively) unflavored, so I'm suspect I'm more aware of any off taste than people who use lots of flavoring might be.
Way back when, I mixed down a batch of unflavored using the leftovers from the blind test in the Nicotine Comparisons thread. Those 100mg leftovers had all been in a cupboard at room temperature for a few months and had all darkened to some degree. I was not happy with the taste of that batch. I vaped it anyway (waste not, want not), but I was glad when it was gone and it was time to make a new batch from base that had been stored in the freezer. That experience provided a good bit of the motivation for this thread.
Yep. I'm starting to lean toward PG is better, but I'm not sure, and I don't think the difference is huge in any case. I started out buying my nic in PG, then switched to VG later, based on Kurt's writings. Since I've been using my nic on a FIFO basis, I've never mixed down any of my VG nic. I suppose I should do that at some point, but it's unclear when that might be. I'm not sure I have any VG nic down in here in FL, and up in PA, I made a big batch of unflavored not long before I left, which will have to get used before I make another batch up there.
