I use a lowish percentage of flavoring, I use FA so far, and it's usually between 2--4% max, but I tend to be conservative with flavorings, and some just need more flavor than others. I'll be branching out into some other flavorings soon, and I plan to try some different companies, so I'm looking forward to it. I tend to make pretty uncomplicated recipes (at least, I have so far) but will sometimes blend compatible flavors in a tank--e.g. coconut and caramel for example, or mixed berries with a bit of coco, with a few reasonable swirls, things blend together rather well, if I find a combo I really like, sometimes I'll combine it in my next "
juice".
I found doing it that way gives me a lot of control over finding out what I like, as well as the ability to "try" a mix and get a sense of how it will vape together before I combine it in a 40 ml bottle. I've had to pour out a few disgusting tanks, but not really any bottles of flavor. It just kind of made sense to me to do it that way, but I'm a tinkerer and I like creating my own recipes rather than following one, necessarily, and that's how I learned to cook (with a few notable exceptions) read a few cookbooks and just began playing around with the seasonings and whatnot....
Also, if I hate something right out of the gate, I tend to try and make it vapable by adding sometimes the oddest stuff-- I turned my mixed berry
juice into "Appalachia flavoring" by adding storebought brandy and coco and steeping it for a while, it ended up tasting really good (to me), it really cut the sheer sweetness and intensity of the flavor. Could have been horrid, but I rather liked it.
I had to wait for my tastebuds to grow back in before making the most basic of flavors and even having an idea of what might be "good" though.....
