One of my coworkers gave me a bag of Kirkland Green Tea yesterday to try out. It’s actually not bad. It is, I would go so far to say, quite pleasant. A mix of sencha and matcha—after you brew the tea for 30 seconds, you empty the matcha dust from the bag’s packet into the tea. There was a little notch cut out on the tag so it could hang on the side of your cup, which seemed like a keen idea, but my mug was too thick for it.
Well done, Costco! (Sadly your website appears to be broken, so I linked to Amazon up above.)
