everyone keeps talking of this steeping thing... what are yall putting into your liquids ( solids) that requires steeping? Tea is steeped, wine is aged, whiskey is aged.... juice is aged... unless you are putting tobacco in your juice....

think about it people.... do you smoke your juice too???

It's a bit like calling real cigarettes analogs, no?

Pretty sure there's nothing analog about them--and nothing digital about a great quantity of e-cigs.
We all know what's meant, though.

Actually, if you want to be precise, it's a diffusion thing--similar to steeping, as a matter of fact. If I throw a couple of menthol crystals into a PG or VG diluent, they most certainly do not age--the flavor molecules just diffuse.

Wine and cheese and people age. :D

That said, there are many terms that have been agreed upon and generally accepted by most in the vaping community, like analogs, vaping, e-cigarette. steeping...whether we like them or not. I don't like 'analogs' but I'm not going to fight it. I don't much care for 'vaping', either, come to think of it. But it is what it is. Language is a living thing. It evolves.

Relax and happy vaping!

I have two small bottles of the same flavor e juice, mint oreo. one has 0 nic and the other is 12mg nic. what I have found is that the 0 nic juice I have had for over a month now is still clear. the 12mg nic juice I just got 3 days ago ( both made by the same local vendor) is starting to get a light brown color in the bottle! the flavor is the same so far but time will tell. I also have several other different flavors of 12mg juice from the same vendor which some have turned really dark and others have remained relatively clear that are all a month or older. this has led me to think that some flavors react differently to the nic. also noticed that some have a better taste while others get worse over time!! it's all trial and error!!

I feel that it does. Nicotine "juice" alone has a peppery smell to it. When mixed to make e-juice and then bottled, many have a chemical taste when vaped right away. Oxidizing or aging (aka steeping) your juice in a dark, cool location with their caps/lids off will allow the ingredients to meld and cure, much like a wine or spirit.

Wait, I'm supposed to take the caps off when steeping? Forgive me I'm new. I have been sitting on this nicoticket order but caps on. Had a ml of each flavor when first arived. And yes it tasted chemically. Having some now after 18days from mix and it seems better but maybe still a little chemically. Been scratching my head wondering if my taste buds are broke. Why's this winning all the awards when I've got at least two fairly random selection juices here I like better. I thought my tounge just needs to adjust but maybe a longer and more correct steep is in order??

Cap/tip off for 12 hours to allow the alcohol to evaporate. This is called aerating.

Leave the cap off for more than 12-24 hours and you 're wrecking your juice.

Steeping is:

Cap/tip on in a cool dark place for a week.
try it.
Like it? use it.
not yet? another week.
repeat as necessary.

Some are good to go OOB but will get better with time.
I'm sensitive to the perfumey flavor unsteeped juice has so I leave them for at least a week.
YMMV

What precisely is the nicotine oxidizing ? If oxidation is happening this juice will go bad pretty quickly. I understand the venting off of PGA " don't use it, don't have it in my concentrates", why would it be in a premium eliquid. I think steeping is allowing the flavors to envelope throughout the thick base. Similar to mixing gunpowder, if you put the ingredients together they just burn, if you filter the ingredients a few times and ball mill it for 12 hours it burns expeditiously. I definitely concede to a color change with nic and it is darker at higher concentrations. Sometimes the color is simply brown, sometimes a pinkish look. Something is going on in that liquid cig in a carni bottle. Can we get a chemist to chime in ?

I feel like it does. Some more than others. And it isn't always a good thing. For example, I vape Skedaddles from Old Pueblo Vapors, and I love it steeped - but then the Hummingbird Nectar from Kick Bass I have to vape straight out of the bottle, and if it steeps for a week, I toss it because it tastes harsh and very chemically.

The steeping process for e-liquid is essentially a chemical reaction taking place by way of oxidation of nicotine. The physical reaction taking place, known as diffusion, occurs among the PG/VG base & the flavorings unique to your e-juice. Now, does the oxidation of nicotine really effect or enhance the flavor notes in your e-liquid? I'm wondering if the two reactions are mutually exclusive & thus, the oxidation of nicotine should be treated merely as a gauge of how far along the steeping process is. Your thoughts??

Isn't the Problem with Explaining/Quantifying the concept of "Steeping" the Lack of Universal Physical Parameters for e-Liquids? And then to Compound this, we have People Using Slang, Improper Words or Assumptions about Physical Phenomenon that May or May Not be True.

"Nicotine Oxidation" seems to be somewhat In Vogue way of Defining what "Steeping" is and what it Does for People.

So what about people who DIY 0mg? There is No Nicotine Oxidation going on for them because the is No Nicotine. But they seem to need to do the Same "Steeping" Generally to obtain the Flavor they Desire in a Given Mix.

Also, are All Nicotine Bases at the Same Level of Nicotine Oxidation when the End User Buys it? Are they at the Same Level of Nicotine Oxidation when they Use it? And How does PG:VG Ratios and mg/ml Concentrations effect Nicotine Oxidation?

Seems to me if Someone likes to do In House Experiments, that they would Oxidize some Unflavored Nicotine Base at the Same PG:VG and mg/ml level as their Final Flavored e-Liquids and then see if there is any Difference to Usual DIY process?

And then that Leads to your Question.

I'm wondering if the two reactions are mutually exclusive & thus, the oxidation of nicotine should be treated merely as a gauge of how far along the steeping process is.

Two events are Mutually Exclusive if they Cannot occur at the Same Time. So for our e-Liquids, Nicotine Oxidation Cannot occur at the Same Time as Molecular Diffusion.

Since the Nicotine is in a Liquid Form, and since it's Molecular Polarity allows to remain Mixed and Not Separate, there is going to be Some Degree of Molecular Diffusion.

So as Long as Oxidation of the Nicotine is Occurring, the Two are Not Mutually Exclusive. If the Nicotine can No Long Oxidative, the Two Events can No Longer Occur at the Same Time. So then Yes, they would be considered Mutually Exclusive.

Was the Term you were looking for to describe Nicotine Oxidation and "Steeping" Non-Dependent Events by any Chance?

First, I really disagree with all those who say "let it sit with the caps off". This causes unnecessary oxidation of both the nic and the flavorings, and loss of flavor.

Instead do this:
1. Shake the bottle well.
2. Take the cap off, squeeze the air in and out a couple of times. Put the cap back on.
3. Shake it again and put it back in the cupboard.

Do this a couple of times a day until any chemical smell is gone. After that just let it sit (with an occasional shake if you feel like it) but with the cap ON!

Oxidation is NOT a good thing, and is not what you want to happen!

If it was nicotine oxidation we were looking for, don't you think people would suggest leaving the cap off for long periods of time? Or maybe blowing bubbles with an aerator? Or why people with O nic liquids still steep?
Yes, leave cap off long enough for alcohol to evaporate out, but not longer then 12 hours or a day.

Yes, we are looking for "diffusion", of the flavors evenly across the liquid... as the word "steeping" implies.
each liquid component of your e-juice has different viscosities and specific gravities and take time to even out.

On some, there are possibly other changes of the flavors go through with time (or application of heat), but nicotine oxidation is not the one change that is the key in all e-liquids.

Why?

----------------------------

Oxidation tends to break down flavors and make them weaker or less "accurate".

(Also leaving the caps off tends to make a lot of the flavor evaporate into the air). You want the volatiles to escape (and saturate the small amount of air at the top) but lose as little of the flavor as possible.

When nicotine oxidizes, it develops a harsher taste, and most people don't find this particularly pleasant.

One of the most effective methods of steeping (sorry, BunnyKiller!) is to use an ultrasonic cleaner. This helps the liquid mix evenly much faster, without introducing extra air into the liquid. The micro-mixing of the different components is really what it's all about
