Kent, alden, anyone..... I've asked before, but in your estimation, how long will the nic survive in a frozen state?
Our resident chemist, Kurt, has had some nic base in freezer for over 5 years now - either a PM to me or a post in DIY eliquids or both. He tests the nic level every so often and reports no degradation. He expects it to last even longer....
I consulted him when I made a big bulk buy from Decadent Vapours. [cliff notes] - Amber Glass - PE caps (no rubber), leave some space at top, not a lot - it won't freeze. Freeze nic base and diluent (PG or VG) but not flavoring. Keep flavoring in dark, cool, dry space.
