Ishimoto Kawaguchiken Iwai no Shiro Matcha – Ceremonial Japanese Matcha

Clean, brisk, and distinctly bittersweet.

Iwai no Shiro by Ishimoto Kawaguchiken is a stone-ground Uji matcha with a light body, refreshing vegetal character, and a more pronounced bitterness.

Compared with smoother and more umami-forward matcha, Iwai no Shiro offers a crisp, straightforward flavour with gentle savoury notes and a clean finish. Its stronger bitterness makes it especially enjoyable for those who appreciate a traditional, brisk matcha profile, while also pairing beautifully with sweet desserts.

Best For

• Traditional usucha / thin tea

• Hot matcha

• Iced matcha
