Amazing for brewing lose leave tea!
This is my second time purchasing this item. It is an amazing product. Easy to use and keep in fridge. Parts are easy to clean. Wish it came in a gallon size. Pretty colors, light in weight, durable construction.

Super convenient
I like how convenient this is, I want to get more as it has made making cold brew teas so easy that I am refilling it and reusing the tea leaves multiple times a day. Due to the way it filters, it's also convenient to put fruit to add more flavor. The plastic seems sturdy but also I kind of wish it was glass like their pitcher style. That one is also good but harder to put fruit slices in.

A must for ice tea lovers
Got this after seeing it as a restaurant! Perfect for keeping tea in the fridge and super easy to clean. Love how it comes apart so you can really get it clean.

Pretty Excellent
I've had the bottle a few days and have been having a lot of fun with it so far, it works quite well and pours smoothly and isn't leaky when agitating (so far). I ordered the 1200ml version, which I enjoy but I'm considering purchasing another so I can have more cold brew on hand at any given time. The sizes are small by my standards, which to be fair are those of an American glutton- super size me baby. So, it was slightly disappointing to purchase the largest size available, have it be made out of plastic (as an environmental scientist, this makes me feel terrible and I would love to avoid it while also satisfying my need for MORE) and then still run out after three healthy glasses of iced tea. Anyways, these are good products by my measure thus far, and my current plan of recourse for curing my deficit issue is to buy another.

I love this tea bottle
I was spending two bucks a day or more or buying green tea in plastic bottles at the work machine but we had free green tea bags. This has already paid for itself. It looks great too!!! Works wonderful. When I can save up enough, I plan on getting one for home as well.

Have 3 now
Green lid for green caffeinated leaf tea and pink for herbal. Love it so much my kiddos got themselves one. I throw in whatever I’m in the mood for but usually it’s just loose tea, sugar or sugar substitute and lemon juice. I don’t like how the lemon rind affects the flavor after a day and ruined the batch so I stopped adding fresh lemon. But I use one tablespoon of loose leaf when I first fill it. It doesn’t take more than 5 minutes to flavor the water if it’s a quality leaf. I drink about half and then refill with more cold water and let it sit do its thing in the fridge for a strong brew; sometimes I just drink it immediately. All good tea leaves can be cold brewed according to my tea store, so I’ve experimented and found that to be true for me so far. I used to make sun tea in the summer and winter I’d boil water on the stove and then bottle them for cold brew. Now I just use this and save myself so much time

Great bottle for tea or flavored water
I have the smaller version of this and I'm super glad I found this larger size. It's super easy to use and clean, and the design makes it easy to store on it's side in the fridge and no leaks. Super easy to make some ice tea or cucumber water. We keep two in the fridge at all times, especially for hot summer days. Sturdy construction and good looks.

It think it's a great bottle, wish the bottom part could be put into a dishwasher as well but it's fine to hand wash. The filter could be better since I put some loose tea and it wasn't very fine to catch the loose leaves.

以前に使っていたガラス製のピッチャーが割れてしまったので、代わりに買いました。少し背が高いですが、私が使っている冷蔵庫のドアポケットには問題なく入ります。蓋は、他の人も書いていましたが、真っ直ぐいれないとしまりにくい。テーブルの上など、平らなところに置けば、さほど難しくはありませんが。横置きする時は、蓋などをしっかり閉めておかないと漏れます(当たり前ですが)。中を洗うのも簡単で、便利に使っています。

Fantastic for teas! Easy to clean. Large capacity (1200ml) has me reaching out to this the Ka-Ku more than my Aisne (700ml).

J'ai acheté cette bouteille pour faire des infusions à froid (thé, fleurs, eau de concombre) et j'en suis pleinement satisfait ! Le design est simple et élégant. On sent l'ingéniosité Japonaise simple et efficace. 5 éléments (corps de la bouteille, filtre, joint, haut de la bouteille et bouchon) facilement assemblables, démontables et nettoyables. Vous fixez le joint dans l'intérieur du haut de la bouteille, vous y vissez le filtre, vous mettez ce que vous voulez infusez dans la bouteille, vous la remplissez d'eau, vous refermez avec le haut de la bouteille, vous vissez le bouchon, vous mettez la bouteille au frigo entre 12 et 48h selon ce que vous infusez et l'intensité que vous souhaitez et... VOILA : Une boisson délicieuse et naturelle à déguster. Le filtre est parfaitement adapté, les mailles sont de la bonne taille pour ne laisser passer aucun morceau tout en laissant passer ce qui a infusé. Tout ferme parfaitement et il n'y a aucune fuite. Vous pouvez laissez la bouteille dans votre frigo à l'horizontale sans problème. Elle est en plastique solide (contrairement aux autres modèles HARIO en verre qui sont un peu fragiles) et passe au lave vaisselle. Je recommande donc à 100% cet article.

冷茶用に買いました。 上の色付きの部分と下の透明なボトル部分の蓋が閉めにくい事があります。横にしても漏れず見た目が良いです。
