I’m new to Vaping & DIY E-Liquid and I really want a chocolate flavor liquid. So I found this local chocolate food flavoring in my country Indonesia which name is koepoe². It has a lot of ingredients in it which I don’t know, one of those is cocoa liquor.
Please, do not use this flavouring. Inhaling vaporised fats is indeed very dangerous as you clearly say from the Vitamin E death last year.
(caramel is probably best avoided as well).
If you like coffee and chocolate, one of the most efficient flavours for me in this profile is tiramisu from Flavour Art, thick mix of coffee and chocolate. Very easy to taste from two drops per 10 ml, guaranteed without fats and FA is one of the better testing manufacturers. One of my test recipes that was pretty decent.
