re: No telling what the juice will be like when you finish it
Love to hear some suggestions on how to store it and how long it might be good for.
My thoughts when ordering it were partly based on wanting to stock up before regulations hit. Also I figured it could not taste any worse than the millionth MArlboro I was still lighting up 20 something times a day. I see it as a vehicle to get nicotine in my body. Simple as that. It is the first flavor I have felt like I could vape forever with a few other things thrown in.
The *best* way to stock up in terms of ease of storage and keeping the nic good for the longest amount of time is to get nic in a 100%VG base and plan to add the flavorings and any PG yourself. VG with nic is slightly more stable than PG with nic over the long term (years). There are posts about it in the DIY forum if you're interested. Having said that, the difference in PG with nic and VG with nic in terms of long term stability is indeed slight... but there is a reason VG based nic is favored by DIYers, too.
Having said all of that, this is what *I* would do if I had that much *premade* juice on hand (and in fact, I do have a 236ml bottle of Pumpkin Spice I did exactly this with).
Decant some of it into 30ml or 50ml bottles for your immediate daily use.
Decant the rest into glass bottles (cobalt or amber, doesn't matter which as long as it'll block light). Then, stick the bottle/bottles in the fridge or freezer. The juice won't freeze because home freezers don't get cold enough to freeze PG/VG. How many bottles to use depends on how you plan to steep it.
Re: steeping - cold slows down nic degradation, but juice won't steep if it's cold. There's two ways to handle that.
You can steep the whole giant bottle *first* by leaving it at room temp till it tastes good. (This is what I did.) Then put it in the freezer till you need it. Decant your freezer-stored juice into your "immediate use" bottles as needed, let it come to room temp, shake well, and you'll have "pre-steeped" ready to vape juice.
Your other option is to put it in the freezer unsteeped decant/steep as needed, but be aware that if you do it that way, the clock has essentially stopped on steep time from the minute the juice goes in the freezer, so you need to allow for steeping from the time you take it back out of the freezer. That's why if you put it in the fridge/freezer unsteeped, you may want to use smaller bottles, because smaller bottles steep faster. If you freeze it presteeped, you can put it in a few larger bottles, decant into your ready to use bottles as needed, and be good to go.
I do all my longterm storage in glass because plastic can potentially leech things into the juice over a long period of time.
Just like with steeping, everyone has their own storage process, but those are the basic principles.
