Hello everyone. I am in no way a master, but this is my compilation of what I've read thus far. Please feel free to correct me on %'s and anything that should be added. Furthermore, I have tried to give the OP's credit for their information; that being said I compiled this list from reviewers and members from this board, as well as the venders. I in no way came up with any of this on my own.
TA- Tobacco Absolute (ALC) (Contains EM) You can buy this premade from TFA
1% in most tobaccos; makes it pop. Its that missing element.
Purified Medical Inhalation Saline .5% 1 drop per 10ml (Bakery and Tobaccos) Adds body and enhances juice. May add salty note.
EM = Ethyl Maltol Crystals to liquid - 1/4 tsp. to 10 ml warm PG or PGA (Some say VG will work)
Tiny Bit (A fraction of 1% in your mix) - Gives a "body" to the vapor and may slightly reduce sharp notes.
A Bit (Close to 1% +/- in your mix) - As above but will take the edge off sharp notes and may very slightly sweeten.
A Bunch (1%-5% of your total mix) - As above plus sweeten
A Load (10%+ of your total mix) - Cotton Candy flavor (EM info written by Hoosier)
ACV= Apple Cider Vinegar 1-2 drops per 5ml (Tobaccos)
Lemon Juice - 1-2 drop per 5 ml (Fruits)
Sour TFA Malic Acid 20% solution. 1-2 drops per 10Ml Makes Fruits pop
Tart and Sour (Citric and Malic Acid) 1-2 drops per 10Ml (Higher % creates Jolly Rancher-like effect) Makes fruits pop
Menthol Crystals to liquid 50/50 in PG or VG
Start a 2% (Some say 5%) depends on how much you like menthol.
1 drop to 10ml brightens fruits with menthol actually tasted
Vape Wizard (MTS) More,Thicker,Smoother .5-2% - Smooths things out, cuts down harshness, creates body. Can dull flavors, use sparingly. (Possibly Oakwood flavoring)-patkin
Hoosier says; MTS Vape Wizard, aka VW. MTS is supposed to stand for More Thicker Smoother. It can help some mixes produce more vapor. (Some flavorings actually reduce vapor production) It can smooth or help blend flavors together. I use it in the 1 drop per 10ml to 1 drop per 3ml range, but usually start closer to the middle at 1 drop per 5ml to see if it will do a darn thing to the mix. Sometimes it seems to work wonders, but I've never had it make a mix worse.
Bitter Wizard .5-2% - 1 drop to 10ml - Removes sweetness, adds dryness. May hurt blend (start with small batch).
Hoosier says; Bitter Wizard. This makes things bitter. Mostly useful for tobacco blends, but sometimes a bit of bitter will make things much more flavorful. Again 1 drop per 10ml to 1 drop per 2ml is a useful range. I usually start at the tiny 1 drop per 10ml and work up if it is needed.
Magic Mask .5-2% - Reduces acid perception without modifying PH. Adds mouthfeel.
Hoosier says; Magic Mask. This is weird stuff and I find it is more likely to hurt the taste of a mix than to help it. It can take really sharp notes down and make them palatable. I usually start over if I have used this in a mix and it helps and always start over if I have used this in a mix and it makes it worse. It may work better for you than me. This is the last thing I ever try on a mix.
Smooth - .5-2% - Rounds out any harsh edges, provide a thick mouthfeel, softens the high notes of your blend while boosting your background notes.
Sweeteners - Sucralose (Most Common) Better Stevia (Alternative some say chemical taste) 1-2 Drops per 10 ml or 1% adds strength in flavor and sweetens greatly. (Remember; less is more, start small) Mostly used in fruits, candy, and bakery flavors.
Other Sweetener Options TFA Marshmallow- adds moistness and sweetens. TFA Molasses adds sweetness + a trace spice. TFA Brown Sugar Extra adds sweetness. Some custards and Vanillas have also been used (Also known to brighten other flavors).
Ethyl Vanillin 10% Solution Crystals to liquid ¼ tsp to 10ml PG? Unsure
Great sweetener + Vanilla taste.
Caryophyllene Oxide TFA 1% PG .5-1% - Adds a woody notes to tobaccos and mixes well with some fruits. - eikon
AP = Acetyl Pyrazine 10% soulution .5-2% Adds a bready/nutty note (Can turn into Frito taste if overused) Use sparingly.
Aldehyde L-14 Peach TFA - Diluted to 1% - Use at .5-1% Be extremely careful with undiluted solution. Adds a very dry, not sweet, peachy note - eikon
TH= Throat hit - Capella's Horchata, want2vape's Caramel #2 Also, some cinnamons. -
PGA= Pure Grain Alcohol (Everclear/151 Rum/Vodka - high proof) 1-2 drops per 5 ml = Throat Hit
Side Notes
Higher vg mixes 50%+; flavors are less intense May require more flavor
70pg-30vg seems to be the commercial "norm".
Too much flavor will create flat taste
adding more flavor will most likely not make it better.
Steeping
Steeping is king of all secrets. Store the juice in a cool dark place. Shake it a couple times a day while steeping. If it has an alcohol additive; store it with the cap off for the first 24 hours. If it doesnt taste good, check it a week later, if it still taste bad, check it a month later, if its still bad throw it in a cave and check it six months later
after that, it may be no good. Dispose of properly; DO NOT DUMP IT IN THE DRAIN! Nicotine is poison.
