I accidentally left an unopened bottle of GT Kombucha tea outside the refrigerator. Discovered it the next day… It was in my basement, thus cool and out of sunlight. No where on the bottle, could I find where it says to "keep refrigerated" OR "refrigerate after opening"–although it is refrigerated in the store. and this is also how I keep it. Does anyone know if this bottle would still be safe to drink? Especially if it tastes and smells normal?

Hotter water leads to more caffeine release and a more bitter flavor as it cooks the leaves. If you're serious about the taste of tea, set up four cups and pour water into them: The first boiling, the next after 30 seconds, and on down. Use a cracker between each sip; the later teas should taste slightly lighter and sweeter, and the middle two especially should have a distinct delicate green tea taste. For loose-leaf you normally use a slightly lower temp, while typical teabags need more coaxing to get the flavor out. There are websites that actually list perfect temperatures and steep times for each individual variety, but it's also a matter of taste.
Green tea snobbery can be a little like wine snobbery, the sky's the limit for how sublime you want to go, but at the same time anyone can drink and enjoy it.
Black tea on the other hand doesn't have such delicate taste because it's already pre-cooked. (Oolong retains a little of each nature.) How hot you should make it depends only on how much you like the taste of Bergamot (for Earl Grey) or whatever additives are in your tea, how bitter you can stand it, and how much caffeine you want out of it. The hotter and more bitter it is, the more the tea will cover up the flavor of any additives. Steeping time affects bitterness as well, of course. I'm not entirely certain, but I believe that bergamot oil will also start to evaporate if it's boiled, but I assume you don't boil your tea.
I have no idea how it would change the taste of chai, as I've never made a really good one myself. I typically make them from the powders, and I've seen no difference at all in taste between hot, warm, or even cold water, though the texture changes slightly - it doesn't mix perfectly in cold water. Those powders probably have most of the variability processed out of them. I assume this goes double for hot chocolate, since most of the mixes don't even have real cocoa anymore.
Aside from the possibility of boiling off oils or partially burning green leaves into black, I don't believe the water can get hot enough to change the chemistry of the drinks.
I don't think I've ever seen peanut butter grow mold, natural or commercial, refrigerated or not. What will happen with natural peanut butter is that the fat (of which there's plenty) will go rancid over time.
The oxidation process that leads to rancidity requires heat, light, and usually oxygen; keeping it in the refrigerator will therefore slow the process down significantly.
Manufacturers are probably not required to put the "keep refrigerated" warning on nut butters because eating rancid food technically won't kill you or make you seriously ill. When a product says to keep refrigerated, sometimes that's for safety, sometimes it's just for quality - in the case of peanut butter it's typically the latter.
Commercial peanut butter has a ton of sugar and other preservatives, which is why refrigeration is not necessary, even for quality purposes.

Seems as if it must be kept refrigerated. First I found that it ships refrigerated and has a somewhat short shelf life. Then, I found a picture of the label and it clearly states 'KEEP REFRIGERATED. - DO NOT SHAKE.'
Here's a link to the Amazon page where you can see a pic of the label.
