I store any e-liquids I won't be using routinely in "my" refrigerator including flavorings, whatever nic base is open (and not frozen) and some liquids I don't use a lot of like my wholesale WTA liquids (the one in use, I leave out). I keep most of my mixes in amber bottles to avoid light issues, but I don't worry about heat as much, since I tend to be in the middle of the steeping process when I start vaping it (sometimes... Not so much now that I've gotten an assembly line going). Otherwise, it's in a dark place in my vaping closet. I do probably have too many bottles out, but it's really difficult when I'm vaping so many different flavors at a time. If I've made a double mix and it's done steeping, I will put one bottle in the refrigerator, but I'm not entirely sure that is needed, even (I use 60 ml bottles... So... most will be done with in a few months or at the most, 6.)
I'm actually seeing a NEED to slow down on mixing and vape away what I have. so probably won't start DIY again for a month or so as I just got a bunch of new flavors that I am really enjoying and I made 90 mls, not 60.
I have noticed my storebought vanilla that I couldn't vape (didn't agree with me) has darkened considerably over the months, but they are in clear plastic bottles. With amber bottles, I don't tend to see much darkening, even if light is present.
