Verdict: Delicious. Strong strawberry flavour, with hints of having eaten the meringue-y crumbs that have fallen off the pavlova after it's been cut... Miraculous (though I'm not sure that this may be everyone's idea of an appetising flavour?).
The ingredient list is also reasonably mystery-free - though it does list "Flavours" as one.
I'll look past this however as next time I want to try this as iced tea. Yum.
