About

The Hario Ka-Ku is a 40 oz cold brew tea bottle designed for effortless overnight steeping. Add your loose leaf tea, fill with cold water, and refrigerate overnight. The next day, pour directly into your cup. The built-in strainer keeps leaves out so there's no extra straining or cleanup required.

Hario is one of the most trusted names in precision brewing, and the Ka-Ku reflects that. Simple, well-made, and practical for daily use. At 12.5 inches tall and 40 oz capacity it holds enough for multiple servings, making it a great fit for anyone who drinks cold-brewed tea regularly.

    I love these cold-tea brewers! I have three: two are in the fridge (one brewing, the other ready for drinking) antall times and the third has been washed and dried, ready for the next batch to be brewed. I get two brewings from each batch.

    The only con I have is that they do stain from the tea, so I use vinegar periodically to get rid of that as much as possible. Also make sure that you thoroughly wash and let them completely air dry between uses (which is why I ended up with three) to prevent molding.

    I drink a lot of green tea daily and love the convenience of using these brewers. It is always ready for me when I need to refill my mug. Totally mess-free and super simple.
