the nic could have oxydized or somthing along those line id contact the supplier and ask them about it, and maybe request a replacement, not sure if it would change the flavor or not, ive never had any of mine get a tint to it or recieved any allready having it, have a good day!-)
It is supposed to get darker with age and some is dark from the day it is made. I suspect that you have one new and one old stock or just the change in production run. Try mixing two small batches 2ml or so as to not use so much it cannot be returned if needs be, and try them I suspect you will have no issues with them at all. Dont add flavour at this point just go straight and check the flavour is ok. Hope this helps..
from here:
Much is made of trying to find the optimal storage conditions for nicotine concentrates to be diluted into working eliquids. Similarly, much is also made of finding concentrates with good pure nicotine.
These are good things, but ultimately, I wonder how much they really matter.
Consider this image from Exogenesis. This is from his vapor trapping experiments where he set up an apparatus to auto-vape e-liquid and electrostatically condense the vapor for nicotine determination:
On the left, you see eliquid made from pharma grade nicotine. On the right you see the same liquid after it's been atomized and condensed.
No matter how well we source and store the stuff, the stuff on right is what we're vaping, not the stuff on the left. After all, the last thing we do before we inhale our precious liquid is heat it up aggressively in a stream of air containing about 20%; oxygen.
I'm not out to make a big deal about this inescapable fact of vaping, but it's at least something to consider when we might be tempted to worry excessively about our concentrates getting a slight yellow/brown tinge.

I'm sure some of the people selling juice (preflavored and unflavored for diy) are on the level but I sure don't trust everyone out there doing it. Not knowing who to trust and who not to trust quickly led me in the diy direction. I ordered capella's flavors and their 0 nic pg and vg. Before mixing my own I got a few really screwed up flavors, read plenty of posts by people who ordered a small bottle of something and then got a big bottle that looked-tasted completely different. If some of the vendors can screw the flavorings up that bad I sure as hell don't trust them on their stated nicotine levels.

I read on Tasty Vapor's forum here that they order bulk from Lorann and Capella and have gotten inconsistency in product, brown chunks floating in Lorann's and such...
Chunks and the like might apply to flavored liquids (and I would consider such to be a defect), but in this case, it sounds like the product is simply nicotine at 48 mg in PG. If one of the bottles was clear and one was obviously tinted, then the most likely explanation to my thinking is that one bottle was considerably older than the other, or more likely, the two bottles were made with nicotine from different manufacturers or different lots from the same manufacturer... and one of the bottles contained nicotine with a more pronounced content of low-level nicotine-like impurities.
Is the tinted liquid "bad"? It's probably fine to vape, but to my own standards, 48 mg nic/pg should be un-tinted at time of receipt.
Well, DVap I'll have to bow to your expertise in the chemistry department here, but I was getting a little sidetracked on what RicksBeach said about the flavorings he got. I was already turned off from Lorann's before I heard that, yet it is widely used and thought people might like the info.
Your explanation is reasonable and I think we all should have pretty high standards for this stuff. Personally, I would be more worried about an inconsistency like this than getting several bottles that have a slight (but even) tinge to them.
DawnsDone, where did you get this stuff from? It's really helpful for others to know things like this so they can avoid vendors who sell bad product. The fact that this happened doesn't damn them, but it is good to know.
So after your old post I pulled out Dvap and this new one I am confused. I've only bought one batch of nic so far, 100mg of Box Elder through Gourmet Vapor. Diluted to ~20mg my bottle of base has a very slight tinge when comparing to a bottle of PG. I'll have to pay attention when I mix another batch, but I know it is slightly yellow, maybe a little more than the left bottle in the pic above.
If we're going to be inhaling the golden liquid anyway, what does it matter? We'll I don't really understand from your post. I started reading some of your blog posts last weekend and found the nicotine forum, but am barely into the Beta-carboline thread. I'm sure that I will find an explanation around, but I don't get what you mean by "low-level nicotine-like impurities" offhand.
Anyhow, there's multiple threads on this every week. What I've been telling people is to not spend something like $90+ on a bottle of ultra-pure nic, when they can get other stuff (at least claimed to be) 99%+, which may have a slight yellow tinge, if they find this on sale for like $60. Do you think this is bad advice in general?
I can't then vouch for the purity of every vendor's nic out there. VoidMist has come up as a possibly bad source recently. There's other places I just plain would never recommend anyone to use for the reason of price like DIYflavor-shack. I'm getting some from NicVape soon and will see how it is (good on price anyhow, and supposedly very fresh).

By low level nicotine-like impurities, I'm referring mainly to trace-level tobacco alkaloids, some of which don't require a whole lot to develop a tint. I recall that Kurt (yet another forum chemist sporting a freshly minted PhD) has fingered his best-guess of the culprit (or perhaps culprits) but I can't recall what it is at the moment.
With many nicotine vendors, the nicotine will develop a tint (often pinkish) only after mixed down with PG. I've come to not really see this as a fault, just a fact of life. The thing to remember is that [Nicotine + Oxygen ---> Oxidized nicotine] is not kinetically stable on the reactant side. The reaction is going to happen, try as we might to avoid it. Keeping it cold only slows it down, but it still happens. The picture that Exogenesis posted of a bottle of clear pharma grade nicotine e-liqud along side a bottle containing the same liquid after being auto-vaped and electrostatically condensed is good for a thousand words. The pre-vaped liquid is crystal clear while the same liquid once auto-vaped and condensed is distinctly tinted. A good bit of oxidation occurs at vape-time.
As for advice on liquid concentrates, really everyone has to decide what they want. I'm torn between two schools of thought. 1) absolute purity, and 2) good enough. Purity equals $$$. If purity is what someone wants, there's nothing better than than a 100 mL bottle of TW Platinum Ice at 54 mg, but at $85, you sure pay for the pharma quality of the nicotine. On the "good enough" side, I can only speak for what I've seen from the vendors I'm comfortable dealing with. There are so many vendors out there that some of them are likely selling stuff that ought to be left to killing bugs. So it comes down to developing relationships with vendors whose products you're comfortable with (and who are willing to take back stuff you're not happy with), or just having done with it and paying the hefty price tags for the top-notch pharma stuff.

I'm no chemist but took my info from a company that makes nrt nicotine and they said it ranges in color from clear to a amber brown tint when made. I for one am not so worried about colour but taste and strength. Great info in this thread guys.
