No idea, but let me guess...Little SPace Drop? Smoke and Prunes? Sunset Virginia (gag)? Am4a or however it's spelled?
Nope!
It was more of an accident than by purpose I discovered this.... The flavor I am talking of is Inw. USA mix!
I was on a months vacation in the caribbean with my wife and children, and I brought with me some ready mixed e liquid, and a pair of protank 1 clearomizers. Unfortunately I forgot to bring with me some spare coils, and had to use what I had at hand.
I brought with me a 50ml premixed Inw. USA mix, mixed at 3% strength. Since we were visiting a lot of my wife's family, and traveling a lot, I never seemed to finish of a tank completely, I kept refilling the tank once it had like 05.ml of e-liquid left.
After a week if refilling the tank, I started to taste somewhat of the analogue cigarette taste.
It just got stronger and stronger (the analogue taste), and after 2-3 weeks it was really on the ashy/analog level of a real cigarette. I tried to burn clean the wire in the atomizer, and rinsing the wicks in hot water, but the taste was still there.
What I think was happening, was that the USA mix (in it self is a ashy tobacco taste), with constant heating and cooling/condensing the flavor (with the constant 0.5ml left in the tank from every refill), the DNB (that's already present in the USA mix) got so concentrated and condensed, it transformed the taste more and more in the direction of a analog cigarette. The heat from the weather also contributed I think...
So, to replicate this (in a much faster way) I think if you start off with a 3% mix of USA mix, and heat/cool it repeatedly (in a open container/saucepan) carefully not to boil it (just to about 60-80 degrees celcius) to when the initial amount of liquid is at half to 1/4, it's darn close to a real analog in taste. Add another dash of DNB (1-2%) and let if steep for 2 weeks.
I would suggest going the route with USA mix, and not directly with DNB (at 3%) because the final "product" with just DNB would taste to harsh.
When I compared my "recipe" to the analog (I took one pull/puff of each in sequence, and changed the order of the sequence) I could not tell them apart! They tasted exactly the same, except the USA mix was more pleasing as it had some other flavor to make it more "enjoyable". And one other thing, I do not get sick/nausea with the USA mix "condensed" flavor, but the analog cigarette made me feal real bad.
Hope this "mishap" can get some of the real strugglers to finally put that combustible stick of death where it belongs - in the toilet!
