Their website says this tea is an aracha (unsorted) tea, but it looks like it’s just the top leaves and bud to me (at least, it is very similar in appearance to Den’s Sencha Zuiko, or their Hashiri Shincha). The wet leaf looked and smelled just like those teas too, though not as sweet as the shincha.
This seems like a typical first flush sencha (in my limited experience)… fresh bitterness, with a vegetal grassiness underneath. There was some sweetness present, but not a lot.
It wasn’t truly exceptional, but it didn’t disappoint, either. If you were to buy a whole bag, at $26 for 100g and shipping (from Japan), it’s not a bad price compared to similar kinds of tea.
