What is the Meaning of Koicha?

Koicha is a type of Japanese green tea known for its thick texture. It’s made by mixing a large amount of matcha powder with less water compared to other teas. This results in a tea that’s more like a paste. Koicha is known for its strong and rich flavor.

The history of koicha goes back centuries in Japan. It became popular as part of Zen Buddhism. Monks used it to stay awake during long meditations. Over time, it became a key part of Japanese culture, especially in tea ceremonies. Koicha isn’t just a drink; it’s a symbol of Japanese tradition, showing respect for history and the art of tea making.

In traditional Japanese tea ceremonies, koicha plays a very special role. These ceremonies are not just about drinking tea, but about a deeper spiritual and social experience. When koicha is served, it’s done with great care and respect.

The way of preparing and serving koicha is an art. It shows the values of harmony, respect, and peace. Koicha helps people connect with each other and appreciate the moment. It’s a way to enjoy the beauty in simple things and share a peaceful experience.

What Does Koicha Taste Like?

Koicha offers a unique taste experience. It’s much richer and more intense than other teas. Its flavor is deep and complex, often described as sweet and umami, which is a savory taste. Unlike thinner teas, koicha can be overwhelmingly bitter when the matcha used is not of the highest quality. Its texture is smooth and velvety, making it stand out from other types of tea. Consider using kotobuki, our highest-grade matcha available for your koicha.

Several factors contribute to koicha’s distinct taste. The quality of matcha powder, which is ground from specially grown and processed green tea leaves, is crucial. These leaves are shaded from sunlight before harvesting, which boosts their flavor. The way koicha is prepared also matters. It requires a specific technique and a careful balance of matcha powder and water to achieve the right thickness and flavor profile.

When compared to other teas, especially the thinner matcha tea known as usucha, koicha is noticeably different. Usucha is lighter, frothier, and can have a slight bitterness, while koicha is thicker, smoother, and sweeter. Again, the highest quality matcha is recommended for koicha.

The difference is not just in taste but also in the experience of drinking. Koicha’s dense texture offers a more indulgent and flavorful experience, making it unique in the world of tea.
