From the dry leaves, I got a whiff of raspberries along with the mossy and mineral, it smells really delicious. The brewed tea smells a tiny bit toasty, a bit vegetal, and a bit spicy with the mineral-y in the first steep. Forgot to time the second steep (oops). Still good. After the third steep, the leaves smelled entirely of spinach, but the brew was less vegetal in flavor. Mostly sweet and spice.
I don’t know what chestnuts taste/smell like, so I cannot comment on that. But there was a more nuttiness that came out for me after the first steep.
I’ve put this tea head-to-head with the similarly priced oolongs from the company, and this one is my favorite for the price.
