Top line: Readily available bagged green tea usually is terrible. This one's pretty good.
Kirkland Signature Japanese Green Tea
100 individually wrapped sachets for $12.79
This unusual tea is a not-so-privately-labeled product packed by Ito En in Japan. The "base" leaf is sencha, for characteristic Japanese-style green tea taste, but matcha has been added, with gives the tea a flavor reminiscent of Yamamotoyama's "Sushi Bar Style" green tea. The bag itself is a very free flowing nylon mesh; steeping is speedy, but perhaps too much matcha powder ends up settling to the bottom for my tastes.
The plastic "string" from bag to tag is rather short, but the tag has a slot pre-cut in it to fit on the edge of your cup so the string doesn't need to be long enough to flop over the side.
The tea seems to finish with a touch of genmai-cha toasted rice flavor. This is not listed on the label, but there were a few flecks of something lighter-than-green in the bag when I tossed it out. Unfortunately, further analysis will have to wait as I can't afford to get too wired tonight. :-)
I purchased this tea for the office because for hygiene reasons, it is easier for "catering" to handle wrapped tea bags than the loose ones (e.g., Celestial Seasonings) and most of the readily available brands are, frankly, appalling. I do like several of the Yamamotoyama products, and I think they are no more expensive than the Costco product, so this might well be a one-time purchase. After all, if you want to entice your clients with your tea offerings, Kirkland Signature probably is not the most impressive name.
