Ok all, have a few questions…
If I have used a tobacco flavor and have let it steep for 4 weeks is that a good enough time to get a good sense of flavor or should it steep longer?
Next question is lowering the amount used…
How much is a noticeable difference? Like if the amount was (throwing numbers out) 2mg and lowered to 1.5mg is that a noticeable difference or should it be more?
Just trying to get a sense of things for changing a recipe, and I know taste is subjective.
Absolutely. If your letting you mixes steep that long then you should test them along the way. You may find that the 2 week mark is better than the the 4 week
With Nicotine or flavoring??
Nicotine lowering 1/2 a pct shouldnt be too noticeable, but if your talking about lowering the flavor that much it certainly can be a big difference
If you’re testing the flavor as a solo, vape it as a shake n vape, (and I do…), like 3,5,7,10 days and so on if I know it needs some time. I think 4 weeks for a tobacco is PLENTY of time.
If you’re taking flavoring, 1/2% could mean a difference. I always start low with a flavor, because you can always add, not take away. If you’re talking nic, 1/2% should not make much of, if not any, difference.
I didn’t browse the other comments, so I hope I’m not repeating. 
Honestly it really depends on the tobacco some steep quicker than others. Flavorah tobaccos for example tend to mature quicker than say a NET tobacco. Lynda_Marie & Fiddy both make good points I usually start taking sample tests within a week of mixing.
And with regard to flavorings the amount used in recipes can definitely affect flavor when it comes to some flavors. Take something like Rich Cinnamon if a recipe says 1 drop and you go 3 drops it will definitely affect the outcome. Other flavors may not affect the recipe too much. That’s why it’s best to SFT and research your flavors to determine at what % works best for. Some flavors like creams, custards, marshmallow may affect the overall flavor simply due to their muting affect.
When it comes to nicotine I usually mix without for testing. Then I add it once I feel the recipe is good. Usually for recipes that I do not plan to vape for long periods of time I simply don’t use nic at all. The amount of nicotine used for me doesn’t affect the flavor at all unless you are going really high. Some tend to drop their nicotine usage periodically by .5% over time to eventually get their usage to 0 nic.
I have been drop tasting along the way. Its not vaping, but gives me a very good idea about the taste.
The nic i find fine, it would be the flavoring. Seems most suggest that a tobacco flavor steep for atleast 4 wks. I love the smell of this tobacco flavor, but in a vape I find it (for me) to be a bit strong. So will be doing it again and adjusting…just wanted to get a sense of how much to knock it down as that part…still learning.
This is what I was looking for…so thank you. And I am ok with you replying with the same info, just means that reinforces the info.
Thanks for that info. I did read alot on the flavor and took the mean % as a starting point. Just for me I find it a bit overpowering. I like the mix, I just find too much of the tobacco flavor. So next go, I will lower down 0.5-1% the tobacco flavor and go from there.
All part of the process…which I enjoy as much as vaping the final product.
Glad to see you asking questions! That’s what we are here for, helping others. 
Asking questions…best way to learn. Got to start somewhere.
i always make a big batch of flavorless e-liquid to have on hand which can be left in the fridge this way I open the Nicotine bottles less often and can mix quickly or dilute anything that is too strong.
i suggest you do something like that once you have your mg levels dialed in. it dosen’t have to be left in the fridge either
Thanks for the tip. Still sorting out my processes. O ce dialed in I’ll het a good system going.
You can always start at suggested median but those can be high. The best thing to do is start lower pct. You can always add a drop or 2 but cant ever take away
This is true. I did go with the median, but definitely gonna lower
@Oldguynew2diy I don’t think you can go wrong with steeping tobaccos and probably even dense, rich custards 4 weeks.
My personal take on NIC in testers, is I run the exact same strength I normally do. It does add something TO it, even if it’s not easily explained, plus that way, what I’m testing, will hopefully be as close to what others will be tasting, i.e. finished mixes, with NIC.
Every tobacco flavor so far has been sitting for 4 wks. Slowly trying some now, taking notes on what i want to change.
I like my Tobacco flavors freshly made… I make 30 or 60ml at a time and Steeping makes no difference with mine.
