Clarity of Color, diluted and undiluted:
The most meaningless parameter in my opinion, but still of interest for ‘cosmetic’ reasons. Nicotine is tinted, period. Nicotine further tints with oxidation, period. I prefer getting my nic clear, just because. Yes its going to yellow a bit anyway. Minor variations in age, storage, etc, will all affect color.
I’m basing the below list on 1) what the nic looked like when I rushed in from the mailbox and opened it 2) what it looked like immediately after dilution
My findings for undiluted and diluted are essentially the same…well kind of (see below). The most clear is indistinguishable from PG, the most tinted is a subtle yellow tint.
Undiluted: XTR = VZ = ECX = WLI > WLR = MFS > RTS
Diluted: VZ = ECX = WLI > XTR = RTS = WLR > MFS
I don’t get it, but I see it, so there it is.
Clarity of Odor, Nosed, diluted and undiluted:
I will rank these in two ways, least odor to most odor, but also compare and contrast the odors because its not as simple as more or less. Again, my findings for diluted and undiluted are identical.
Nicotine smells. Being an amine, it has a characteristic (thank you for the word John!) alkaline aroma. I can smell ‘alkaline’ or ‘amine’ in all of these nics after they have been warmed slightly.
Of note: I can’t smell anything in the unwarmed XTR and VZ
ECX, WLI: Very slight basic aroma
RTS: There’s a basic aroma, probably in class with MFS, slightly less.
After my previous review I started to feel it actually smelled more than MFS. But I’ve realized its not exactly MORE aromatic, just different, in a bad way for me, so I experience it as “more odor.” There’s something else ,which is unique compared to all the other nicotines I have on hand. It’s kind of amine like, but also like a soggy, rancid tobacco, or rotting nuts. That’s a terrible description, but I don’t know how else to describe it. Whatever it is I find it bothersome.
WLR: Alkaline aroma, on par with RTS
MFS: Very pronounced alkaline aroma, in line with ECX, RTS, WLI and WLR, just louder. It hits you in the face when you take a whiff. But to me, it smells like “strong nic,” and doesn’t bother me so much, but I can see this being very annoying to some.
Clarity of Odor, nosed: XTR = VZ > ECX = WLI > WLR > MFS ~ RTS
Clarity of Odor, Vaped:
The VZ, ECX WLI, WLR and XTR are essentially odorless. I get a touch of an alkaline aroma from each, all slightly different, I’m having trouble verbalizing it. Its barely perceptible in any event. The dominant aroma is PG/VG.
RTS has little to no alkaline note I’ve found after spending time with it, but that ‘other smell’ I described above is strong and notable, and it again, bothers me. Quite a bit. In fact a get a bit queasy from it after a while.
MFS has the most pronounced alkaline aroma. I can see this being annoying to some, but depending on my mood, I may like it. Sometimes it annoys me, particularly in an aromatic juice. But it doesn’t bother me the way the RTS does, its more ‘intrusive’ and less ‘gross.’
Clarity of Odor, Vaped: XTR ~ VZ ~ ECX ~ WLI ~ WLR > MFS > RTS
Clarity of Flavor, Vaped, not drank :
Across the board I honestly don’t taste much, perhaps ‘alkaline’ but honestly what does that taste like anyway? I don’t know. This is one of those places where smell and taste really bleed in to each other and its very difficult for me to tease them apart. TH and nose burn is probably muddying the waters here as well. Tasting what I'm smelling and smelling what I taste?
MFS and WLR are the closest to having a bona fide taste. Alkaline is all I can really call it. Or nic. Again this will be bothersome so some, and bothersome for certain juices. But sometimes, I really like it wrt the MFS (I haven’t had the WLR long enough to say, but I’m guessing I will in much the same way). When I’m craving an analog, the smack in the face that MFS delivers is the cure, and this flavor is a part of it.
VZ, ECX, XTR, and WLI are essentially without flavor, with subtle differences. Its very difficult to tease apart.
My nose is likely throwing up some interference here, but the rotten nut smell of the RTS has become something I feel as if I can taste, and so unfortunately I cannot say the taste is neutral as above. There is less “taste” than MFS, by far, but I find it much more bothersome, whatever it is.
(For reasons that I do NOT attribute to actual flavor, but more the degree of “pepper” and TH (see below), the XTR, WLI and ECX seem to be the most pure, the VG/PG ‘notes’ are more apparent with these )
Perhaps this is where the uncontrolled variable of PG and VG is playing a role. The differences are very slight, and probably meaningless under normal vaping conditions, but they are there.
Clarity of Flavor, Vaped: XTR = VZ = WLI = RTS? > WLR > RTS ~ MFS
Throat Hit:
MFS, WLI, WLR, VZ, ECX and XTR all have a beast of a throat hit, about equal I’d say, and totally satisfying.
So lets say they are all very close excluding RTS, which lies at the extreme of minimal throat hit.
Intensity of TH: VZ = ECX = MFS = WLI = WLR = XTR >>> RTS
Pepper:
That’s right pepper!
I’ve come to feel that TH and peppery bite are best kept separate in my language and conceptualization, even if biochemically they are related or identical. I didn’t think about this way until I had all of these nicotines sitting in front of me, but the constant back and forth over multiple sittings has made it apparent to me that I need to, at least for now.
I’m totally open to the possibility that this is pure BS, but at this point I think there is something to it.
‘Pepper’ is like multiple, discreet ‘hot spots’ or ‘pins and needles’ on the back of my throat/upper airways.
TH is more like an evenly distributed heat, that isn’t quite as instantaneous or “in your face” or disruptive.
Pepper for me seems to have the ability to satisfy a wicked analog craving, but also throw up some interference for flavor…analogous to a richly flavored dish that simply has so much cayenne pepper in it that you can’t taste as well from your mouth being on fire. Know what I mean? “Dang that’s hot, I can’t taste what I know is there!”
TH doesn’t seem to ‘interrupt’ flavor at all.
The most peppery fellow of this lot is MFS.
Close second place is WLR.
Next comes VZ, then ECX.
XTR and WLI have truly amazed me in that they can deliver a beast of a TH, without much pepper at all. Just a pinch ☺
(Incidentally, I’m vaping TFA Absinthe at 11% at 13mg/ml nic, using WLI. I’ve never gotten a throat hit under 18mg/ml. Never. And here I am with ‘100% VG’ getting a monster throat hit. Is it the flavor? Is it the io6? Or is it the wizard? One never knows).
RTS has virtually no TH, and no pepper.
Intensity of Pepper: MFS > WLR > VZ > ECX > WLI = XTR = RTS
Aging:
Can’t really make too many meaningful observations here, simply for lack of time with a few of the players, but I’ll say what I can.
MFS and RTS seem to be the most sensitive to hanging out in a glass bottle in a dark cool place. MFS tints relatively rapidly, but never gets to the point where you think “omg gross’ at all. Just a yellow tint. MFS seems to develop more alkaline aroma with time as well.
When frozen, MFS holds up incredibly well.
RTS apparently develops more of that horrid aroma that I mentioned above, even in a cool dark place. It now lives in my freezer for more than one reason.
VZ and ECX seem to be impervious to tinting and increase in smell. I honestly don’t get it. Citric acid? Voodoo? No idea.
Can’t say much about XTR, WLI or WLR at this point.
Mixing:
First off, I vape tobaccos 80% of the time, menthol tobaccos 20% of the time. I don’t do fruits or cutes, except occasionally, and thus won’t consider that scenario except speculatively.
I also vape from 18-25 mg, and this is important.
What I’m getting at is, if you vape in the 6-15 mg range, mixing effects will likely be less pronounced, if not absent. But then again, ‘taste buds’ and I imagine “nose buds” and “TH buds” vary
I mean no disrespect to anyone, but it cracks me up a bit when people describe any given nic as ‘smooth’ and then inform me that they vape at 6 mg max. More power to you! But I’m not sure I’d notice any of the above at that level!
Can’t say anything meaningful about WLI, WLR and XTR yet.
(Well I kind of can. As I said above, absinthe with WLI at 13mg. No interference whatsoever, pure flavor, wicked throat hit. But n=1, so… )
But my sense is that WLR will be like a toned down/cleaned up MFS in its behavior.
MFS’ aromatic and taste characteristics seem to amplify when you put it in a tobacco mix. Some will love this, some will hate it. Or like me, you’ll change your mind depending on your mood, desire for an analog and beastly hit, and the flavor(s) in question. Let’s put it this way, when MFS is in a mix,
it makes its presence known. Alkaline, pepper, TH, bang.
RTS’ characteristics likewise seem to amplify in a mix, most notably that ‘rotten smell’ I’ve pointed out. Whatever it is, it gets worse. Recently I made a batch of my pipe extract with RTS at 20 mg after first running it with MFS. It was awful. I tried to give it some time, and the smell just made me sick. It went down the drain.
Made it again with VZ nic. Delightful.
VZ and ECX both work great for me. The VZ makes its presence known a touch more than the ECX, as that pepper thing is more present.
The ECX runs the least ‘interference’ in a mix for me. I don’t smell it. The only thing it contributes is TH and buzz, a touch of pepper. Like the bass player, you don’t notice him, but he’s running the show.
My guess is, that the XTR and WLI will do as good of a job as the ECX, if not better, in a mix. Time will tell.
Summary:
Different strokes for different folks.
The only nicotine I’d be unhappy with here is RTS, I can’t dig it.
If I had to vape one and only one of the others, I’d make it work and be happy.
In sum I think the purest possible taste, while maintaining massive throat hit, is to be had with XTR, WLI, and ECX.
VZ is similar but adds a second pinch of pepper.
WLR is similar but adds a dash of alkaline and two pinches of pepper.
MFS is similar but adds a ½ teaspoon of alkaline and three pinches of pepper.
RTS, sorry to say, is flat.
I will keep playing and experimenting, and edit/change as things go on. I'm sorry for the very unsexy and unprovocative conclusion that we have many great nics to choose from. But I'm very pleased with this conclusion, and hope that they all stay readily available! Keep up the good work gentlemen!
Just one more time:
As I ‘rank’ things in order of ‘most clear’ to ‘least clear’ keep in mind that depending on what you want, or what I want, this is not a ‘best’ to ‘worst’ rating necessarily
Please note that I didn't use words like "BEST" "WORST" "GOOD" or "BAD" ! This was deliberate!
I look forward to your reviews and experiences!
Thank you all, and to all good night
