This one has a sour rose flavor that’s pretty unpleasant, but it can be decently tamed with sugar. It’s really sour, sort of like pink lemonade, but if you think of it in that sort of way, it works. I wouldn’t say I notice lychee specifically, maybe just a touch if I’m paying attention. It’s pink lemonade all the way. The way they create these to steep in cold water in seven minutes just leads to sour weirdness.
