What is Koicha and How do We Prepare It

Posted by Angelina Kurganska on

We’ve already mentioned koicha or “thick tea” in our previous post The Different Types of Japanese Tea Ceremony, but let's do a little recap.


Chanoyu: Chakai vs Chaji


There are two main types of tea ceremony (chanoyu – 茶の湯) in Japan. First, the informal tea gathering known as a chakai – 茶会. Second, the formal one known as chaji – 茶事.

Chakai is a relatively simple tea gathering which includes some wagashi (Japanese sweets) and thin tea (usucha). Chaji is much more formal. It usually consists of a full-course kaiseki meal followed by wagashi, thick tea (koicha), and thin tea. A chaji lasts as long as four hours. In between, there are some small breaks for the tea guests to walk around the garden by the Japanese tea house. 

When it comes to drinking matcha, more are familiar with usucha. Koicha, on the other hand, is for the traditional Japanese tea ceremony. Furthermore, tea masters use exclusively top-grade ceremonial matcha for its preparation.


Koicha might, in fact, be the thickest tea you will ever drink. Only about 50 ml of tea is prepared and the consistency is like a thick syrup more so than tea.

How Do We Enjoy Koicha?

When sipping koicha, it will slowly but surely proceed to greet you. Meeting you with a brief moment of intense umami and a long-lingering sweetness. Similarly to gong fu cha when we intake a concentrate of all the tea’s best qualities all through one tiny cup of brew.

This is indeed an experience.

It is common to enjoy Koicha alongside wagashi, the sweet-and-salty traditional Japanese sweets. Drinking it on its own might be too intense even for the experienced matcha connoisseur.

In Japanese tea cafes, it is not uncommon to find desserts such as sweet mochi and red beans topped with koicha. And most recently “koicha affogato”, ice cream topped with the thick green tea.

Many believe that koicha is a true way to intake the quality of the matcha to its fullest. Similarly to how many tea drinkers believe that gong fu style tea is the true and only way to honor your loose leaf tea. Ultimately it is up to the drinker. However, we do recommend trying it at least once!

How To Make Koicha


Follow these simple step-by-step instructions to prepare a delicious cup of thick koicha tea. 

  1. Sift the matcha powder, making sure not to have any lumps
  2. Place 4 chashaku (4 grams) of the matcha powder into the chawan
  3. Pour 50ml hot water into the chawan and whisk using the chasen

The whisking style differs slightly from usucha. For koicha, we use slower motion, "massaging" the tea powder more so than actually whisking it. The resulting mass will be of a thick, syrupy consistency and a vibrant green color. It is important to note that when it comes to this type of tea, we don't strive for the same foam that we all love in our usucha. 


Make sure only to use top-quality ceremonial grade matcha. Otherwise, you will end up with a rather bitter beverage that is not pleasant to consume in such a  concentrated quantity.
