I let all my tobacco flavored juices sit a month before I even try them .. it's just automatic as they always need the time to mature.
Fruits are OK almost right away depending on what else has been added.
The lemon juice is for fruits, the vinegar is for tobacco, and "darks" like chocolate,
They each do a different PH thing.
If your into making your own tobaccos, pick up some "Vape Wizard"
It's used for DIY, but could be added to a flavor you think has to strong of a throat hit or needs to be a little smoother.
If you use it, give it a few weeks to do it's magic
It only takes 1 drop for 6 to 10ml. If you use to much, it will mute the flavors.
Just a few idea's, have fun
Those are good tips about what to add to which kind, thx! But I got a Green Apple from MadVapes that wasn't good when I first got it, tasted more like green bananas. ugh.. but maybe it's time to give it another try, it's been sitting for over a week now. If it's not a lot better, I might try the lemon -- would a lemon flavor do, rather than actual lemon juice? I get droppers at Hobby Lobby, in the candy-making area, and I saw they had Flavor Art flavors for excellent prices, but they're just sweet flavors, no savory or tobacco. I really need to get a dripper thingie for tasting all these flavors, these big tanks are kind of a pain for that. Maybe next month.
I'm always trying to get *more* throat hit, not less!

Why do you think I like PG-based so much! But I'm definitely going to try the cider vinegar in both the FA Virginia flavoring, and that last Virginia I got, from primevaping. I got an "extra flavor hit" and it's definitely the same FA Virginia, same exact green/vegetable/celery kind of taste/smell. But that first one, with the chemical taste, urgh, that stuff is nasty right now. If it "ripens," great, but it's going to sit a LONG time before I try it again. The hangsen Virginia actually turned out very well, after about a week; at first it wasn't really *bad,* just kinda... flat. Today when I tried it, I thought it was quite similar to the taste I was looking for, though just a *hair* towards a pipe-tobacco sort of taste. So I ended up mixing it with the MFS VG-Virginia, since the Hangsen's was quite thin and pale, I figure primarily PG. The mix turned out quite well!
