There’s a little hint of a smoky/bitterness I’m picking up. But it’s also a bit like miso/umami. Just a hint. Overall sweet, not overly vegetal.
Edit: I’ve found that if I do a quick rinse of the leaves with hot water (basically immediately discard the first steep) the bitterness is gone, but the toasty/smoky remains, as does that umami-like smell and hint of flavor. I enjoy the tea much more following this method. But then you get to the last sip/swallow in the cup… bitter again.
