My opinion is that everybody but myself has very poor taste in flavours.
Personally I like baccy flavours but at much weaker concentrations than most folk like.
I have never bought a juice that did not have too much flavour. I mix my own.
i sometimes like a little fruit in my baccy or a little booze flavour.
Sweet juice is wrong and custard is especially wrong and biscuit flavours will destroy any juice.
Much of what I dislike seems popular.
