Learn about Koicha Matcha Green Tea

All About Koicha

May 19, 2017

Ever wonder why so many matchas are dubbed, “ceremonial?”

The answer is very traditional!  There are two ways to prepare matcha—usucha (“thin tea,” and how the majority of matcha drinkers encounter it) and koicha (“thick tea”) style. For normal, everyday matcha preparations, usucha is the preferred method. All it takes 2-3 chashaku scoops (roughly 2-4 grams) of powder, whisked with (up to) 4oz. of 150-175°F water. The resulting brew is usually foamy, spry, sweet, with a gentle umami tone throughout. Koicha is a different scenario entirely.


For one, Koicha – a slick, syrupy matcha preparation generally made from matcha that has been crafted from plants over 30 years old – is the chosen method for most Japanese tea ceremony schools. Secondly, the resulting brew is as the name describes; a thick tea. There is some debate among many matcha resources as to what equates the perfect powder-to-water ratio for preparing koicha. Typically, the amount of matcha powder used is 3.75-4 grams, but the water ratio can very depending on what resource or tea school the drinker is referencing. Some will say as low as .65oz of water; others recommend as high as 1.75oz.



Whatever the chosen powder-to-water ratio, the result should be a brew that looks more like a syrup than a tea. And of equal importance, the matcha used should be of high quality. Terms like “ceremonial grade” are thrown around quite a bit in matcha circles, but there really isn't a specific quality grading curve for matcha. That and such a judgment can be entirely subjective. Traditionally, the term ceremonial was (and should be) reserved for matcha that is quality enough to prepare the intense experience that is koicha.

A handy recommendation: the brighter green the leaf powder, the higher quality it is. Another good indicator is the smell. High quality matcha powder will have a more full-bodied, sweet aroma. Grassier, rougher, dull aromatics in matcha indicates that the powder has had some exposure to oxygen during processing.


Our Kokoro falls into  the quality, koicha category. This tea is the highest grade, ceremonial matcha  in the Mizuba line, and it shows in both powder color and smell. Kokoro’s powder is fine and bright green, whereas the aroma invokes silky textures and naturally sweetened kelp snacks. Of our line, it is the matcha we recommend for koicha style preparation.

When prepared koicha style, the result is a thick syrup of green goodness. Unlike usucha, it may take a little bit of time to reach your mouth. But when it does, the drinker is greeted with a chewy brew of straight umami coupled with a silky sweetness that just lingers on the tongue.

For each sip, it is recommended that even the most seasoned koicha drinker take a bite of something sweet. In most tea ceremonies, or commercial tearooms, matcha is paired with a small snack (or wagashi), something that is both sweet and savory. Reason being, the taste of koicha matcha is strong, and—for some—might need to be gentled with something sweet to fully enrich the experience.


While koicha style matcha is not for everyone, it is worth experiencing once—if only to see how versatile a high quality matcha can be. Whether your preference is thin tea or thick tea, a good matcha should be able to match any drinker's palate. Your ritual is your own.


As with any tea, the best way to drink it is the way you enjoy the most. Preference is entirely up to the drinker ­– if you want to shake up the powder in a mason jar or put it into a cake, or diligently whisk it with the chasen every morning - that is entirely up to you! All we, as matcha purveyors, hope to do is point you in a direction that best suits your tastes. Enjoy!
