From Leaf to Cup

From farm to cup in six steps: Shading, Picking, Steaming, Drying, Sorting and Grinding.

From Leaf to Cup

Shading — illustration

01 / 07

Shading 覆

Tea plants are covered with mesh for three to four weeks before harvest to block sunlight, boost chlorophyll (encourage a richer green colour), and increase sweet amino acids (deeper umami profile).

Picking — illustration

02 / 07

Picking 摘

Only the youngest, softest topmost leaves and a bud are hand-picked or machine-harvested by skilled farmers during the spring flush.

Steaming — illustration

03 / 07

Steaming 蒸

Fresh leaves are steamed for 15 to 40 seconds at ~100°C right after picking to soften the leaves, stop oxidation and lock in the vibrant green colours.

Drying — illustration

04 / 07

Drying 乾

Steamed leaves are cooled by wind over 2 to 3 cycles, then dried, to prevent mold and stabilise the tea.

Sorting — illustration

05 / 07

Sorting 選

The dried tea leaves are then sorted, separating stems and leaves via airflow and sifting, resulting in pure leaf material known as tencha.

Grinding — illustration

Grinding 挽

The tencha leaves are fed into traditional granite stone mills that rotate slowly to grind the material into an ultra-fine powder without generating heat.
