Yeah I have already read that supermarket flavourings will require more drops then concentrated flavouring and when I have checked the ingredients they are just Water, Ethanol and flavouring. I did notice some that have either Rapeseed, Sunflower and or essential oils which I avoided.
Is there a way of reducing the water/ethanol to prevent too much of a watery outcome?
The vanilla flavouring I picked up states Water, Ethanol and Extract of Vanilla, the other 2 is Water, Ethanol and flavouring
