Think it's some kind of exotic tea. My guardians travel a lot so they have a huge collection of souvenirs from outside. It might even be tea you've never tried before. I'd like that too. Food tastes better with other people.
Now, that would be quite interesting, to drink a tea I have never had before... and I would admit it would be very surprising. I have had many teas. Not that I would be considered a true master, or anything.
And with others, yes. Anything to eat or drink is much better with others.
