I could pick up the umami as well, it made for an interesting cup. Not grassy either. Light n smooth.
Edit: had some more today, and let it cool off more. There’s an immediate light sweet note followed by the umami flavor. It’s almost meaty. The finish is crisp and peppery. I don’t think it pairs well with sweets such as cookies, but by itself or with a savory meal, it would be fantastic.
