I have kept all my eliquid, always, in my refridgerator. I have some small bottles I am using in the room near me, and when they get empty I refill them with what is in the refridgerator.
I am speaking of several hundred bottles kept in there over a period of in many cases 12 to, meanwhile, more then 18 months for quite a few of them.
I have never, ever, had even one bottle of e-liquid that went wrong up until now, either in taste or in nicotine-height that I could discern (I do find I can discern pretty well if something has more then I am used to or less then I am using of nicotine in it - and I do test new bottles when they come in too, to make sure I am not just getting used to lower amounts without recognizing this).
I know Sun has had a batch that at some point went wrong. And he had been keeping these in his fridge. I have no idea what went wrong there; perhaps the batch just wasn't good to begin with even, I don't know - I don't doubt his story for a second of course. I am just putting my experience next to it.
So you won't hear me saying that fridge = wrong. In fact I have even experimented with keeping some bottles in the freezer at -18C. No problems with that either...
