The cherry blossom season is finally here in Tokyo. There are still chilly days, so hot tea is a must-have item. This time, we will introduce ITO EN's "Keep in My Bottle" series, which is convenient even in places where it is difficult to dispose of garbage.


Keep in My Bottle is a series of tea bags that you can drink deliciously even in your own bottle. There are four types of tea, "Jasmine Tea", which is a blend of high-grade tea leaves, and "Premium Rooibos Tea," "Rooibos & Herbal Tea," and "Serial Tea," which have zero caffeine.


The triangular pyramid tea bag has no handle, just pop it into a bottle or mug and pour boiling water. When it reaches the desired strength, you can drink it as it is without taking it out.


When I compared the tea that had been put in the tea bag for 1 hour with the tea that had just been brewed, there was a difference in the color depth, but there was no astringency, and both were the same deliciousness. It seems to be useful in places where tea bags cannot be thrown away or in the office.


By the way, it takes a little time, but watering is OK (extraction time is about 2 hours). It's really convenient to get ready quickly on a busy morning, so please give it a try!
