Of the three flavours I tried from Ghostea, I expected this to be the sweetest and it was actually probably the least sweet. I mean, still pretty sweet but it wasn’t the cloying syrupy flavour I’d braced myself for. Otherwise, it does taste pretty much exactly like you’d expect a blue raspberry drink to taste like. Very typical commercial blue raspberry candy flavour. Just a little bit of acidity, but more from the popping boba themselves and less from the “tea”. Like the other drinks, the boba were hard to distribute while drinking from the bottle.
It’s the only one of the three I might consider buying again. Probably only in a pinch as a soda alternative, though…
