I put it all in the freezer because I didn't have glass bottles to decant it in. It does make more sense though to divide into smaller bottles and just pull one of those out instead of the jug.
Yes, smaller bottles almost filled to top. You want to minimize air exposure over time.
I divide into 120ml. for storage once open, with 16 50ml jars for ready grab and go.
Each jar handles monthly mixes or more......depending on family needs.

I guess it was a dumb question, huh. Just nervous about such high concentrations of nic. It's so toxic. 
Thanks for the link. Going there now.
