Early Grey Tea is gross.
Artificially flavoured teas used to be popular back in the 80s. I remember even when somebody else was drinking it or preparing it, the smell was disgusting.
Artificial pineapple flavour is awful. One time I ordered a pineapple juice at a pool hall in Indonesia, I have no idea why I did that. Just a temporary craving I guess. What they served up was some really nasty pineapple cordial, obviously made out of artificial pineapple flavour and sugar, and they put some dodgy pineapple pulp into it so it would look more real. It was awful, one sip was all I could take. I like artificial strawberry flavour but it tastes very different to actual strawberries.
