About Chaseki Gokou

Chaseki Gokou is part of our Ceremonial Matcha collection and is a Chaseki Private Blend product - sourced from Uji, Kyoto and sold exclusively under the Chaseki brand.

Gokou (五光) is one of Japan's most revered matcha cultivars, historically associated with the Uji region and prized for its exceptional depth, complex character, and the combination of buttery richness, deep umami, and floral-chocolate layering it achieves at high cultivation levels. It is relatively rare in pure single-cultivar form - most matchas that include Gokou blend it with other cultivars to moderate its intensity and cost.

Chaseki Gokou presents it unblended: the complete, unmediated character of the Gokou cultivar at koicha grade from Uji, Kyoto. Buttered spinach, avocado creaminess, asparagus depth, three-nut warmth of hazelnuts, walnuts, and chestnut, rose and osmanthus florals, vanilla sweetness, and dark chocolate and cacao nibs on the finish. The full character of a cultivar that has defined Uji ceremonial matcha for centuries.

Taste Profile

Mouthfeel: Rich, full Finish: Long Umami: High Character: Buttery, floral, dark chocolate Flavor Notes

Chaseki Gokou opens with a rich, full mouthfeel and a long finish. Buttered spinach leads the vegetal character - deep and full. Avocado creaminess follows, smooth and coating. Asparagus adds a clean, direct green dimension. Hazelnut nuttiness runs through the mid-palate alongside walnuts and the warm sweetness of chestnut. Floral notes of roses and osmanthus layer above the richness - vivid and aromatic. Vanilla integrates smoothly through the body, warm and cohesive. Dark chocolate and cacao nibs close the finish with depth and warmth. High umami sustains throughout the cup and into the long finish.

How to Use Chaseki Gokou

Best suited for:

• Koicha
• Usucha
• Clear-style preparations

Chaseki Gokou is built for koicha. The Gokou cultivar's buttery richness, avocado creaminess, dark chocolate depth, and high umami all intensify under thick concentration - the roses, osmanthus, walnuts, hazelnuts, and chestnut warmth are fully expressed at koicha weight. In usucha, the long finish and full-range character produce a deeply satisfying, complex bowl. In clear-style, the asparagus, avocado, and floral notes are vivid and expressive.

How Chaseki Gokou Compares

The pinnacle of the Chaseki Private Blend single-cultivar range. Chaseki Uji Hikari (THB 1,500) is more accessible - slightly astringent, juicy, savory umami, roses, osmanthus, and cacao nibs in a more latte-friendly profile. Chaseki Izumo Midori No Mukashi (THB 1,860) is the Okumidori expression - fresh cut grass, peas, avocado, and fruit notes with latte and mocktail versatility. Chaseki Gokou stands alone at the top: the richest, most complex, and most koicha-oriented matcha in the Chaseki Private Blend range.
