The Tenth-Dan Tea Master

Guardian of the brand — responsible for the taste of every cup.

TEA MASTER

A tea master is not a mere appraiser.

We do not think of the tea master as simply an appraiser. The tea master is the guardian of the brand: facing leaves that change every year with climate and growing conditions, at times recreating the unchanging taste of Kyoto Chanokura, at times drawing out the fullest character of that year's tea — bearing final responsibility for the taste of every cup.

JUDAN

Keisuke Hori and the rank of tenth dan

At the heart of our quality stands our tenth-dan tea master, Keisuke Hori — winner of Japan’s national tea appraisal competition, making him Japan’s foremost tea master.

The tenth dan is a rank only 30 tea masters have attained in the roughly seventy years since the competition’s founding in 1956 — the highest grade, held as the pinnacle of the craft in the tea industry.

From appraising raw leaf to blending and the final sensory inspection — every tea we ship passes his eye and palate before it reaches you.

THE WORK

The unchanging taste, and the taste of a single year.

To recreate an unchanging taste amid a changing climate — or, when a particular year and field stand out, to leave the leaf unblended and let its once-in-a-lifetime character speak. Deciding which path to take is itself the tea master's work.

He also designs for the seasons — the youthful freshness of new tea, and the deep, matured character of autumn tea aged over the summer (kuchikiri).

FIVE SENSES

Inspection by the five senses

Alongside instrumental analysis, the tea master's senses are the final measure.

Sight

Compared against standard colour samples: are brightness and saturation within range? Are the particles uniform?

Smell

The dry aroma before hot water, and the infusion aroma after. Any trace of oxidation?

Taste

Brewed, whisked, and drunk. Judging the balance of sweetness, umami, bitterness, and astringency.

Touch

Felt between the fingers, checking moisture content and the fineness of the particles.

The tea master's work is one with our system of quality.
