Uh I mean it’s a good strong matcha drink shot in a can.
For an Ito-En, generic but solid company, they can’t mess up. nothing remarkable but it’s a solid matcha with no odd or artificial aftertastes. For those unaccustomed to making matcha you definitely can use this in drink mixes, probably easier. I also enjoy it with sparkling water if I had the time/resources in my cabinet.
But the main reason I feel most people get this is the same reason they get canned coffee. Easy to drink, easy to transport and you need that caffeine. I got these at work all the time back when I worked near a Japanese supermarket. Also a steady flow of energy with no crash, unlike coffee.
