I've purchased some e-liquids online, and just today bought a few small bottles to try at a local store. When i got home, being the curious guy i am, I looked up the flavours online at the manufactures website, and they are not listed. So now i'm thinking, is there anyway to know the age of the e liquids? could it be i purchased some that were made years ago and no longer made? How hard would it be for manufactures to stamp a date produced on the labels, and why don't they.
how to know age of e-liquid

IMO those dates are meaningless.
If it tastes good and vapes well...it's fine.
What kind of things are you concerned about?
If you google the flavours, you may encounter chatter about them around a certain date to give you a ball park estimate.

In fairness, not putting a date on something (like e-liquid) can sometimes improve your chances of selling it at full price sometime down the line. Plenty of vendors have inadvertently shot themselves in the foot over-stocking on certain juices (and printing the date on) that are perfectly good to vape for another 12 months or so.
I'm not disagreeing exactly and take your point, of course.
When it turns dark (if it didn't start that way) it's usually going bad and will taste off. I've had juices start turning dark fairly soon after buying, who knows if they were old already, and some last years. Other than that, some juices will get better for a long time, others peak out fairly soon.
some companies actually put the date made on the bottle... others dont.... when they get old enuf they grow fuzzy stuff... 
some juices can age ( not steep) for over a year and become awesome... HHVs Dragons Fire is one to mention... also I have some DIYNETs that have been aging for over 2 yrs and have become fantastic... all depends on the process as to how it was originally made and the type of flavors/tobaccos used... I did have one DIYNET that went bad and ended up smelling like ammonia after 3 months..
I was told by a vape store (don't think I'll mention them) that they don't stamp dates because their juices are very stable, etc., etc. If I find bottles of vape from say, 6 years ago, I trash them. Simply because that particular vape store would have been more than happy to sell me cinnamon and vanilla flavors, which really aren't that safe. When I asked, I was simply told by the sales associate that their flavoring was "FDA approved." Yes, I have things that are approved for removing nail polish, but I doubt I'd VAPE IT.
I think you have to find vapes that work for you/seem safe, use reasonable judgement, etc.? I'd think storing liquids in a cool, dark place would also be a good plan. As well as using reputable buyers.

The problem is that no one really knows. It's one of many issues in the vaping world that hasn't yet been studied properly.
I've used year-old juice with no problems. You can't really go by colour because ejuice will naturally darken with age, and it isn't necessarily a problem. The best general rule is that if it tastes odd or unpleasant, throw it out. Oh, and it should be stored in a cool, dark place.
<2 years is not a bad theory. I know some juices are well off even after a year, they taste dreadful.
Some liquids also get so dark they are (even worse) coil gunkers... Custards often get like this.
Yes, over time premade juice will darken... This is (another) reason why I'd like to be able to DIY juice at some point, so *I* know when I've made it and that I'm storing ingredients correctly, etc. Also, price and availability are a factor.
I'm not sure that expiration dates will help much, though they'll likely become a standard, I think. But, it will be kind of like tinned food... I have no issue with using an expired tin of tomatos to make pasta sauce if it looks/smells/tastes okay.... If it's begun bulging, however, or the tin became dented? I trash it immediately, regardless of date.
I guess I'd say if you're uncertain, try vaping a tiny bit of it in a smaller tank. If it's completely foul (to you, some flavors are going to be foul, regardless, to me) and you know what the juice USED to taste like, you'll have a fair idea without using too much juice, though I guess everyone has to find their own method.
Imagine if there were an expiration date on cigarettes? There isn't, at least in my state.... That being said, I did tell my husband that if Armageddon arrives, I was going to need a HUGE pile of tobacco in one corner that I could smoke, (and possibly nest in), and I'm sure I would have been quite happy to smoke it until the food ran out. I was kidding. Mostly.

Nicotine oxidizes fairly rapidly, causing it to darken over from the clear liquid used in mixing to an amber color. It does not affect the flavor that much, as far as I can tell. Flavors can change colors, too.
Freezing can slow the reaction.
I have about 40ml left of a 100ml bottle I bought two years ago and I still mix with it. I found two bottles of 12mg/l liquid last month in an old laptop case. One was a concoction called Monkey .... (oreo flavor). The other was my DIY copy of JC's Red Oak Domestic (tobacco). Monkey .... hasn't been sold in three years and I can't remember when I mixed the DIY stuff.
But both were still fabulous.

Might I suggest;
If you are a manufacturer, put a batch number on your product.
If you DIY, put the date on the bottle.

Imho it probably depends on the flavors of the juice, i've found one recently that i've had stored for at least 1-2 year and although it didn't taste awesome it wasen't all that awfull.Note that it was in a dark drawer so idk if that has anything to do with it.......
