My bottle that you can choose from various features such as design and size. When I was looking for something good, I found "TWISTEA PLUS" which is a combination of a teapot and a tumbler.

◆ What kind of product?

A 2in1 tea bottle that combines the functions of a teapot and tumbler. By twisting the main body, you can separate the tea leaves and tea, so you can keep the desired extraction concentration. The bottle is made of Tritan, which is also used for baby bottles as a highly safe material that does not contain bisphenol A (BPA). The size is about W67 x D67 x H215 mm, and the capacity is 400 ml (effective full capacity when used is 290 ml). You can purchase it at general stores, home electronics mass retailers, and online shops. The estimated price is 2,600 yen (excluding tax).

◆ I tried using it

First, open the lid on the filter side, put in your favorite tea leaves, and close the lid tightly.


Turn the bottle upside down and pour hot or cold water from the spout side to extract the tea.


When it reaches the desired strength, twist the bottle to close the valve and separate the tea leaves and tea. If you open the valve again and add hot water, you can enjoy the second brew.

◆ Honest review

The good thing is that the bottle has a double structure so it doesn't get hot even if you hold it, and you can keep the desired strength just by twisting it. I'm grateful that it doesn't become too astringent even if I leave the tea leaves in it!

What I was interested in was that the fine tea leaves came out of the filter and entered the hot water during extraction. I tried it with several kinds of tea leaves, but it seems that small ones inevitably pass through the filter.


Since the bottle size is large, it is recommended to use it at home or office rather than for carrying around. If you don't want to prepare a teapot and a tumbler separately, why not try it?
