I am sure the FDA article scare yesterday has a lot of people thinking about stockpiling nic base in the freezer. I would be lying if I said I didn't order yet another liter of 100mg last night.
Long story short, when the 100mg arrives, I immediately cut it with PG down to 50mg. I always buy a fresh new gallon of PG when I cut 100mg nic base down to 50mg. Figure freshest is best. I bottle the 50mg into glass liter bottles, tape around the top of the cap, and store it in my garage refrigerator freezer. As of now, I have 5 full liters of 50mg and the new bottle of 100mg on the way.
I have the nic test kit that you can measure your nic level of any juice or base. Ordered it online from http://eliquidtest.com/
I test my nic everytime I receive a new 100mg batch AND I test it everytime I fill my mixing bottle I keep in the house with my frozen stash in the freezer. I do this to monitor if the nic is degrading or oxidizing down to a lesser nic strength as it is being stored.
The bottle of 50mg nic base that I am currently using was purchased in December, 2011. It is 20 months old, stored in the freezer the entire time. I just filled my in-house mixing bottle last week and when I used the eliquid test on the nic, it measured at 48mg. Everytime I have done the eliquid test on this bottle I get 48 or 49mg as my result. The standard deviation for error with the test is +- 1-2 mg, so the nic is measuring right on target, so to speak. Plus, I cannot say I am totally precise when cutting down the nic...it is possible that I had a skosh more PG in the bottle and it was 49mg, not 50mg when I cut it down originally.
What this test does is tell me a few things. One, this nic is almost 2 years old and has not experienced any nic oxidation or degrading yet. Second, visual inspection of the nic is virtually the same. It MAY have the TINIEST hint of yellow to it, but I have to look pretty hard at it to see it. Third, smell is no stronger than when I purchased it. Also no foul or funky smell to it at all. And fourth, flavor of the vape is exactly the same as the first bottle of juice I made with it over a year ago.
I do not vacuum seal or anything like that. Just pour into either a clear or amber glass bottle. I do not pad it or put it in additional boxes, the bottles are just laid flat on the floor of my freezer. It is not my in-kitchen fridge, to that helps.
Long-term storage has been a bit of an unknown, but based on the experiences I have had so far with storage of my nic, I believe that long term storage capabilities are longer than we may have thought. While the 1 year shelf life is a general guideline, I have exceeded that by almost a year already with no bad effects on my nic.
Hope this helps those of you who are considering a big bulk nic purchase in advance of possible FDA regulation changes.
