I keep my flavors in the fridge in a tupperware type container.
I am afraid that freezing them may cause separation or something.

Shelf life of unmixed pg/vg base & nic base

6mo to a year for NIC and 3 - 5 years for PG/VG. refridgerating will make them all last longer. Best option for NIC is the freezer (5 - 10 years)
these guys are actually packing nitrogen instead of air in a glass bottle of nic base... I'm not so worried any more about the shelf life ;-)
VG is -64F and PG is -74F. Both are Hygroscopic and likely to contain some water.
I keep my flavors in a kitchen cabinet, just as if I was using them in food -- they're food flavors. One of those 2-tier lazy susan dealies. I think it's probably good to store them more or less in darkness, at a stable temp. As far as I know, their shelf life is indefinite, if the bottle isn't too big. Unless it's a flavor you use a lot of regularly, you probably won't need huge bottles, and there's no way that flavors will be banned, so no real need to stockpile.
The one that does worry me though is inawera; I get my shisha strawberry flavor from them, and shisha being a sort of smokable thing, I have to wonder if they will continue to make that flavor, after the TPD; they're in Poland.

If you get the lower grades of VG they have more water in them and some freeze at well above 0 F.
The more water is some might be why some people complain more about popping in their attys? And more issues with leaking and condensation?
I think I have some Argon in a mig welding tank....Apparently you forgot the /sarc tag.
Argon is ideal because its truly inert and relatively heavy, so it will form a "pool" in the headspace of a bottle.
Today I picked up 2x500ml of PG from my drug store and the expiry date is July 2020. So 4.5 years until the actual expiry date listed on the bottles.
I also picked up 2x250ml of VG and the expiry date is April 2018. So just over 2 years.
I wouldn't freeze either due to the fact that they last a long time, readily available and cheap. The PG was about $10US/l and the VG was "expensive" at about $10US/500ml. Again, this is a local drug mart.
The 1.5l of nic I recently ordered will be split into 50ml and 120ml Amber glass bottles and frozen.

Most liquor stores sell it as wine preserver. Not sure if it is the exact same inert gas, but if it is sold for wine, it should be good for nic. A $10 bottle would likely last me a lifetime.Apparently you forgot the /sarc tag.

Robert,
How do you freeze your nic? I.e. In the 1l bottles, 250ml, smaller bottles? All glass?
Thx!
I believe the wine preservation gas is usually a mixture of nitrogen and carbon dioxide, but it seems to vary by brand. I went through and entire can of it re-bottling 4 gallons of PG and VG in quart size glass bottles.
manufacturers report shelf life of VG at least 2-3 years in unopened bottles (room temperature).
My first liter I split up into 30 ml brown boston glass bottles. that was so I could pull them out one at a time and use them. LOTS of bottles.. A tupperware tub full with bubble wrap around each one... Too much work. 30ML lasts me a couple of months typically. I have not even got into those yet though
Just finishing up on a 125 ml bottle I got 8 months ago... As I empty the 30 ml bottles I will clean and use for juice. My next liter I just got will be going into 125 ml glass bottles which I still have to order. I just put the second bottle in there unopened in it's plastic bottle.I keep my 125 ml bottle in the fridge freezer and refill a 30 ml bottle for use as needed.
All bottles when placed in freezer will need a little bit of headspace for expansion and contraction. I filled mine to the bottom of the threaded neck.
Yep, that's an "at least" figure. Unfortunately, it doesn't tell us what (if anything) will happen to it over a longer time frame, say a decade or two.
My guess: There will be absolutely nothing wrong with it, particularly if bottled in glass with quality caps. I just put up a gallon of PG and three of VG in quart-sized glass bottles. Even if I never need them, I figure I'll open one of each every 5 years and report my findings.
I have already described 20 years old glycerin, but let me repeat it.Yep, that's an "at least" figure. Unfortunately, it doesn't tell us what (if anything) will happen to it over a longer time frame, say a decade or two.

I have in my lab 20 year old 0.5 L clear bottle of glycerin. It was opened 20 years ago. Was opened again and again. Now it is about 0.5 full. Stored on a shelf under bright light (not sunlight). It is of reagent grade (a bit higher than USP), but I would not try to vape it. For example reagent style alcohol (200 proof) is much worse in taste than cheap vodka - it was just cleaned out of different type of impurities. OK, back to glycerin. It is still clear, no odor, may be (just may be) a little bit more sticky than fresh one (I use it only as a hand lotion, when skin is too dry).
I do not recommend to save VG for 20 years, I just wanted to say its shelf life should be quite long. And in a freezer, with nic, it should be really long, longer than that of nicotine anyway.
