Tea Blending

Gogumi, often translated as tea blending, is the craft of evaluating several tea materials and combining them to reach a desired quality. In matcha, it is not simply “mixing tea.” It is a considered production decision that looks at aroma, umami, astringency, color, mouthfeel, and how consistently the tea will taste in the cup.

How it differs from finishing

Tea finishing is the broader process of refining crude tea or tencha through steps such as sorting, drying, cutting, and sifting. Gogumi is the blending judgment within that wider work: deciding which materials should be combined, and in what balance. While “blend” is the common English word, gogumi carries the nuance of sensory evaluation and practical tea-wholesaler experience.

The need for blending begins with differences created earlier in the tea’s life. Cultivar, shading, harvest timing, and field conditions all influence aroma, taste, and color. Processing steps such as steaming, drying, sorting, and milling also affect the final impression. Gogumi is used not only to soften unevenness, but also to shape qualities such as depth, fresh green notes, and a clean finish.

Most drinkers do not perform gogumi themselves when preparing matcha, but they experience its results. At the same concentration, one matcha may feel more aromatic, another rounder in umami, and another more defined when mixed with milk. For a practical way to describe these differences, see ICHIZEN’s guide to what matcha tastes like.

For buyers, the useful question is not whether one single trait is strongest, but whether the balance fits the intended use. For usucha, aroma and finish matter. For lattes, body and clarity through milk are useful indicators. For sweets, color and the way bitterness appears may be more important. After opening, keep matcha sealed, cool, and away from light so its aroma remains clear.

ICHIZEN’s Kyoto Uji matcha is selected and refined by Wakimoto Jokoen, a Kyoto green-tea wholesaler. Their tea-judging perspective, informed by competition-grade evaluation experience, supports the same core idea behind gogumi: understanding each material’s character and arranging it toward a suitable, drinkable balance.
