Passion fruit and mango of course play really well with peach and add some fruityness. The juicy orange citrus and lemon deliver a slight tartness. All rounded of with a bit of coconut which provides a creamy sweetness.
Even though peach is the main flavor here, I like it kind of weak. So I left it at 0.50%. You could up it to 1% or more, if you like it more prominent. You could probably sub most of the flavors except orange citrus, which is quite unique.
