I too would recommend making smaller test batches. Making 30ml of unproven is a shot in the dark, and it will tak emuch longer to steep and mature (if you don't have a UC). I do mine 5ml and usually have 12-15 going at a time to find more ADV's for my stash. I'm working with 40+ flavors even though I've only been doing DIY for a few months now. Some are real easy, some still have me guessing, but I have not had any attempts so bad they got tossed out because I did lots of reasearch first.
I'd also suggest you download the
ejuice Me Up calculator. Lots of recipes already there to weed through. Another rec is to check out
e-liquid Calc authored by ECF member daath. Easyh to use, lots of recipes submitted by ECF members that you can do a search for by flavor. For example, I just ran grape and got 5, peach and got 20 to choose from. e-Liquid Calculator
As I said I am fairly new at DIY too, don't do a lot with fruit vapes, but can add some notes from my short experiences that may or may not help you. Some weak flavors have a small window they work in, use too little OR too much and you won't get them. Strong flavors can be over-powering, so go easy with them. As a new to DIY, doing it KISS works better than trying to get too complex. Single flavor is the easiest, or simple blends while you learn and explore new flavors. Recipes are only a starting place to modify from, what tickles somebody elses toes may or may not tickle yours.
Grape... I don't do grapes except fresh for a snack.
Cotton Candy... stand alone, works well added to other flavors.
Tropical Punch... no idea.
Pina Colada... stand alone that may work, but I like my own verson better.
Apple... can be a stand alone, great with Caramel and sour (or sour apple).
Orange Cream... weak flavor.
Licorice... overpowering, go easy, some like lemon with it.
Mango... weak flavor.
Peach... lots of fruit vapers love peach stand alone or mixed.
FWIW
