I am somewhat new to discerning the quality of Green Tea, but am trying to learn. This is a very interesting tea. It meshes some of the pleasant astringency of good Sencha with the mouth viscosity and sweetness of Gyokuro. The aftertaste is long-lasting. It definitely provides the umami flavour. Be careful about brewing it; I put too many tea leaves in my first batch and it was almost a bit bitter. This time I used fewer leaves and it was marvellous. Highly recommended.
