e-juice darkens with bad taste

[Methusela]

I thought I read somewhere (here) that one should keep their e-juice in a cool, dark place for storage.
I recently bought a new iClear 30s tank and filled it with my favorite juice, normally a light brown color.
I left the filled tank out on my dining room table one day and noticed the e-juice turned a dark brown color.
I suppose it was exposed to indirect sunlight, since we have a large picture window in that room.
The taste was kind of bad too, so I emptied the tank and rinsed out the coil, wasting over 3ml of e-juice.
Was the indirect sunlight what caused this or would even incandescent lighting do that?

In 1 day, I wouldn't think light could do that. Did you use it all day too, or did it just sit there? All my juice is exposed to light, at least the juice I plan to vape in the next month or so does... (Long term stash is in the freezer in Amber glass bottles).

I had my fav juice, mother's milk, turn really dark and taste bad too. Thought it was a coil and wasn't. I had it in my backpack for like a week.

The process I'm thinking you're thinking of is called 'steeping' it. I would email your e-juice manufacturer and see if that's something they recommend doing with all their juices. I'm not sure if all juices are meant to be steeped, though I doubt that would matter. I'll link a video that I found since I just bought a juice where many have recommended to 'steep' it for two weeks before giving it a good vape.

Vape juice imo becomes bad in 6 months even when in a good glass bottle(helps 1000%).Most people will not eat frozen chicken let alone fish.Any air or heat does bad things to my juice(disclaimer south florida 80 in house 65 humidity).My advice buy small .think muffins walk away from old bread.

my juice does darken in clear tanks but does not taste bad. I use 2 Iclear30S tanks and fill then and let them sit overnight before use as they take a longertime to soak into the wicks. I use them for non-sweet juices as I have found sweet juices do seem to gunk the coils quickly giving a burnt taste quicker

I live in Florida too and keep my juices in a tin in a locked cabinet...have some over a year old that taste fine. most are in dark glass however

I have found the coils last a long time with my juices as long as I rinse and vodka soak them every 15 tanks

Any tank will darken a juice slightly before it's used up. Heat is the culprit, IMO. Bottom coil tanks are especially prone to heating the juice through the center air tube, which gets warm from the coil below.

Some juices are more likely to darken. Maybe someone can tell us which ingredient causes some to darken and other not so much. Sugary juices are known to foul up a coil.

I find my vodka doesn't last very long when I drink it as I soak my coils...

That's a great way to have the time pass by while it soaks
A little for u, and a little for me. Now we're both clean as a whistle, lol

I allways end up with darker, weird tasting juice when i leave it in my clearos for more than a day. I think the reason is that liquid "washes" the wicks & coil of the clearomizers and all the gunk & filth on them ends up on the juice.

I havent experienced any serious deterioration if left in their bottles.
