The tea contains salted cherry leaves, not cherries themselves, so the cherry flavor is more subtle than one would normally expect from “cherry” items. The aroma lingering in the empty glass is sweeter and has more cherry notes than the tea itself, so it adds an interesting contrast altering between drinking each cup and wafting the aroma.

Tea leaves: 2.5-3g
