Chemical flavor in recipe

[Melicious]

Looking over this flavor list does anyone have an idea as to why my juice is putting out a chemical after taste?

Pineapple (TFA) 2%
Coconut (FA) 3%
Vienna cream (FA) 2%
Custard (FA) 1%

I thought it might be the coconut since it's the only flavor I hadn't previously tried. Anyone else getting a chemical taste from FA's coconut? I guess I should probably do a stand alone test. My vg/pg/nic have been tried and tested in numerous batches so I'm pretty sure they aren't the culprits.

FA is the one coconut I do not get a chemical (or plastic) flavor from, but I never use as much as 3% of it in a recipe.
TFA Pineapple tastes odd to me, something weird on the exhale, but I know many people think it's the perfect pineapple flavor.

I'd recommend trying those two by themselves and see if one of them is giving you the aftertaste you're noticing.

It's a nice looking combination of flavors. If it's the pineapple, it does mellow out with time. Like HIC, I don't use FA Coconut that high. I typically keep it max 1.5%.

I did give it some mellow time, maybe two weeks. I'll try the coconut stand alone and see how it turns out at a lower percentage. I guess I'm too impatient!!! I rarely mix up single flavors. I started out with mostly TFA which is affecting my FA learning curve! I keep forgetting to start small with their stuff. I botched some bilberry. Wow was that bad! The smell alone turned my stomach. Back to the mixing table. Thanks for the input

Bilberry is YUMMY. LOW, low, low...

What a bummer, I wouldn't think the coconut, would give the chemical after taste, but I suppose you'll find out this way. I hope it works out for ya. I do like the combo a lot.
