The teapot is ~80ml. I have seasoned it for about a year of regular use with lighter roast yancha. The description of the pot said it is less porous than typical CZ so I was not too worried about trying DC in it.
For tea I am using 2019 Mi Lan Xiang from Imen, so I don't think tea quality is the issue

I first tried it in a 50ml thin porcelain gaiwan, and the aroma was incredible, but clearly not duped (aroma lasted the whole session).
The teapot seemed to mute the aroma quite a bit, though it marginally increased the sweetness. As an update, I tried less leaf (3g) in the teapot this morning and it seemed to work better. Aroma improved, but still not at the level of the gaiwan. I wonder if one of Imen's small CZ pots would be better for this...
