A bit modest by saying it´ s on the sweet side,... I´m not an expert but this is a bit too harsh with sweetener, so it kills all other flavours. End product after 6 days of steeping reminds me of honey. I will try to dilute it in a larger batch to create mild taste. I got an interesting advice by a seller who said that I should use TFA flavours as 6% max and FA 2% max. End product for my taste should consist 10% flavouring. And another "maybe"; it would be a better ejuice if you would ditch the sweetener because you get enough sweetness from blueberry and add a bit more forest fruit and lemon or other sour citruses that would balance the whole thing. My thoughts,... regards
