I can't imagine not having central AC. This has been the longest stretch of hot weather that I can remember and the humidity has been horrible.
I was thinking about it this morning and was wondering how long it's ok to keep a mixed bottle of liquid. Sometimes I'll get on a kick and use the same recipe for quite a while and will have extra bottles mixed. Then I get tired of it and they sit for a long while. Should I just dump them after a few months or is it ok to keep them?
I have some vendor liquids and some DIY liquids that are a year or two old. Recently, I sampled some of them and they tasted like I expected. I've heard that most eliquid is good for at least two years if kept at room temp. From my personal experience I'd say that's true for most flavors and mixes.
