I would not rate, as I have no idea what I am doing. See for reference:
Exactly me. My first matcha. And I have it for long. Two years. All the time air-sealed.
Anyway, I tried to prepare it best as I can. It is old one (probably) so… okay – still tasty though. Grassy, vegetal, full of umami.
Nice surprise for me. It is drinkable. But probably not so good as new one. But when I do not know where I had put it. Before that I did not had a bowl. Before I did not had a matcha whisk.
Note: I have no idea how hot the water was – 70°C maybe? I guess so. I have no idea about how many powder I have used. Maybe 2 grams, or maybe 3?
Flavors: Cut grass, Umami, Vegetal
