I cold-steeped this overnight, and drank most of it on the bus ride to work. The tartness in it reminds of pink grapefruit, and I get bits of that in the taste, as well as apple flavours. I guess I haven’t actually had passionfruit before so maybe if I had I’d identify this tea better.
It’s slightly tart, but manageable due to the cold-steep, although I’m sure a touch of agave would make it pop. Tasty, but not essential!
