I was skeptical at the idea of a powdered sencha, but this wasn’t bad at all. Now, it wasn’t great, either, but for what it is, it’s perfectly good.
The preparation is simple. You tear open the pouch and dump the contents into a 16.9 oz. bottle of (presumably cold — wouldn’t want to drink this warm, or even room temp) water and shake vigorously. The water turns a cloudy, murky shade of green. The taste is like a weakly brewed sencha over ice — mildly vegetal and grassy, slightly astringent — fairly decent for an iced, unsweetened green tea. It’s comparable in terms of flavor and quality to iced tea made from bagged green tea. I’ve certainly had worse. And I do like the idea that I’m ingesting the actual tea leaf when I make this.
The powder does tend to settle at the bottom of the bottle, but a repeat shaking blends it right back in.
