How to Cold Brew Ryokucha Green Tea

Japanese Ryokucha (緑茶: meaning Green Tea) contains many components good for health.

But have you ever heard about the health benefit of that cold-brewed green tea?

Cold-brewed Ryokucha also brings positive effects on the body. But they are different from the ones with hot-brewed green tea.

The cold tea is umami-rich like high-grade Gyokuro (玉露) tea, even when made from inexpensive tea leaves.

Why is it Umami-Rich?

Here are two main reasons why cold-brewed Ryokucha has plenty of umami compared to hot-brewed green tea.

    • When Ryokucha green tea is brewed with low-temperature water, it doesn’t generate bitterness and astringent taste from catechins.
    • Instead, the umami component, theanine, is extracted a lot.

So cold-brewed Ryokucha has a rich sweetness, packed with umami compared to hot-brewed green tea.

Benefits

  • Cold-brewed Ryokucha contains little catechin with an excellent antioxidant effect inhibiting the growth of human cancer cells. But it is instead rich in epigallocatechin that activates macrophages, a type of immune cell, and helps enhance immunity.
  • Besides, unlike hot-brewed green tea, cold-brewed one contains little caffeine, so it is safe for children.
