My opinion on the Sweet Matcha has not changed with further experimentation. Its just too much sugar to enjoy. The "straight" matcha was more...useful.
It comes packaged in twenty, single-serving wrappers, which are ideal for tea-to-go, convenient. Simply add the tea to a bottle of water, shake, shake, shake, and you have a bottle of RTD tea that is far better than what you can buy at a store. I plan to experiment further with powdered sencha and other teas in the future. I think this may be the answer to my lack of tea at work.
Traditional preparation is where the lack of quality becomes apparent, though to be fair, it has had some tough competition. The wrappers, which are convenient on the go, aren't ideal in this setting. One serving is too much tea for the traditional 3-4 oz of water. The resulting bowl was harsh, overly astringent. Next I emptied a few into a makeshift natsume, scooping out the desired amount, but it didn't taste as fresh, the flavor, diminished.
I don't like posting negative reviews, but Rishi's Matcha was important in establishing a reference point, for me and for my readers. Previously, all the matcha I had been drinking was O-cha's; I had nothing to compare it to, but now I can begin to create a larger frame of reference.
They also sent an ounce of Chiyo Sakae. I have never seen it offered on their website, so I'm not sure what the story is there, if this is something they plan to offer in the future. It was better, not great, but a passable daily matcha, something to sustain me during dry spells.
