Reading this, as well as the user comments, I am inclined to think this is more of a "cream" vape, with vanilla accents; than a "vanilla" vape, with cream accents.
That being said; I would start with the obvious:
TFA Vanilla Bean Ice Cream (as a solo mix; will require exploring various percentages)
OR
CAP Vanilla Bean Ice Cream (as a solo mix; will require exploring various percentages)
(NOTE: the DIY community seems more or less split on CAP vs. TFA Vanilla Bean Ice Cream (VBIC). Some say TFA VBIC has a peppery note, while others say CAP does, or CAP is "flat" and lacks dimension. Only personal trials will tell which is the better choice for you.)
Then, if that didn't work; I would first focus on getting the cream base to my liking, and
then work on the vanilla accent.
Something to keep in mind, while trying to recreate any commercial e-liquid:
- Profit is their purpose
- Profit is driven by sales
- sales are driven by repeat customers
- repeat customers are driven by satisfaction
- Profit is offset by cost of ingredients
- using the least costly ingredients, that still provides customer satisfaction, provides the greatest profits. (more expensive ingredients are not always the best/most profitable choice.)
- total volume/amount of ingredient required (for satisfaction) TIMES cost; is directly proportional to profit. (in other words; the cheapest/most expensive, is not always the "best" for profit.)
- Exception:
- I am a "boutique" e-liquid manufacturer; and I can/am willing, to charge above the market average, to provide a "better" product.
- Don't discount the simple things
- Many commercial e-liquid manufacturers use high percentages of sweeteners to appeal to recent smokers.
- if a mixture seems close but "flat," or "thin," try adding/increasing a sweetener to the mix. This can add a sense of "body," or "thickness" to a mix (though may actually mute some flavor. Primary flavors may need to be increased to offset the additional sweetener.).
Therefore, that being understood, I would look to the "cheaper" ingredients
first. Concentrate manufactures, like FW, TFA, and CAP; are going to be my starting points. They may not be "perfect;" but, am I close enough?
If not, then I will move up the ladder (FA, INW, FLV). If still not good enough; consider other vendors, or variant flavors.
Don't forget to consider where the original manufacturer is located. Chinese manufacturers are likely using Chinese-made concentrates. USA manufacturers are likely to use concentrate manufacturers readily/cheaply available in the USA.
Finally, don't forget, that there are commercial flavor producers, that provide custom concentrates to their customers. These are NOT made available to the general public. If this is the case; one's efforts are "slim to nil."
Almost, ALWAYS, one is better off; trying to get "similar to," rather than "same as." Keeping expectations reasonable, opens much more room for success.
Finding something "as good as...," is easier than, finding something that is "identical to... ." A willingness to "as good as...," often leads to "better than... ."
I hope that makes some sense. If not; say so. And, I will try to do better.
