Nic base and PG decanted and stored in the freezer.
How do I store my VG?.......freezer? (but wont it freeze?)....or fridge?.....or just in a cool place? It's in a ltr bottle at the minute but I do intend to decant it.
Personally, I store the bulk of my VG nic base in the freezer (yes it doesn't actually freeze.. just gets extremely thick) and tend to keep a 100ml bottle in the fridge for mixing (taking it out for an hour or so beforehand so it reaches room temperature and is easier to mix with).
I also store my flavourings in the fridge but tend to keep the straight PG/VG in a cupboard.. if they're in airtight containers that's good enough for me. My reasoning is that I'll use more of the straight PG/VG so it'll probably not have time to go 'off' (if it even does... not had any issues in all the time I've been mixing).
That said, I only mix for myself... if I was mixing to sell/give away juice to other people I might be a bit more cautious.
Thinking about that, I could just see the headlines in the local paper if I made up a bad batch of liquid : "Renowned local idiot poisons herself through ineptitude".
Not offhand, but if it's any guide I bought a few bottles of boots VG a few months ago and it just says best before April 2015 and doesn't say anything about 'use before such and such a time after opening'.
