🟢 Cultivars available at Kanoa Tea
This is why we value single cultivar.
Single-cultivar teas allow the true character of each plant to shine.
Just as a fine wine expresses the identity of its grape variety, a single cultivar reveals the nuances of its lineage – its aroma, its texture, its depth of umami, and the way it responds to shading and climate.
Blending can create harmony, but single-cultivar Gyokuro offers something different: clarity, honesty, and a direct connection to the craft of the grower.
By understanding the cultivar, you understand the tea more deeply – and every cup becomes a way to experience its origin with greater intention.
This is the philosophy behind Kanoa Tea’s approach: to honour the individuality of each cultivar, and to share its purest expression with you.
Thank you for exploring our Gyokuro Cultivar Lexicon.
We hope it has brought you a deeper understanding of how each cultivar shapes the flavour, aroma, and character of Japan’s most treasured shaded teas.

to honour the individuality of every cultivar and to share its purest expression with the world.
