160-Year-Old Family FarmGrown in Wazuka, Kyoto

Made from single-cultivar Gokou tea leaves — also written Goko — grown on a 160-year-old family farm in Wazuka, Kyoto, this ceremonial grade Gokou matcha is a pure expression of one of Uji's most umami-rich cultivars.

Gokou was developed in Kyoto for high amino-acid content, and it is prized for depth and body. After several weeks of shade growing, the first spring harvest leaves are processed into tencha and stone-milled in small batches into a fine powder, preserving the cultivar's rich aroma, creamy texture, and vivid green color.

The result is full-bodied and smooth: pronounced umami, balanced natural sweetness, a gentle nuttiness, and low bitterness. Substantial enough for thick koicha as well as thin usucha, its creamy body also makes an excellent matcha latte with milk or oat milk.

The leaves are grown pesticide-free — without synthetic pesticides or herbicides — though this Gokou is not part of the farm's JAS-certified organic range. Single-cultivar Gokou is a small portion of Uji's production, so each seasonal batch is limited.

Goko Matcha: The Rich, Umami-Forward Cultivar

Among Uji cultivars, Gokou (also written Goko) is prized for depth and body. Developed in Kyoto for high amino-acid content, it produces matcha with pronounced umami, a creamy mouthfeel, and a rich, naturally sweet, lightly nutty character.

Where Saemidori is bright and sweet and Okumidori is balanced and rounded, Gokou sits at the rich, full-bodied end of the spectrum — the most umami-forward of the three, and substantial enough to prepare as thick koicha as well as everyday usucha.

Pesticide-Free Cultivation in Wazuka, Kyoto

This Gokou matcha is grown without synthetic pesticides or herbicides on a multigenerational family farm in Wazuka. While this particular tea is not part of the farm's JAS-certified organic range, it is cultivated with the same care — relying on soil health, careful shade management, and slow, attentive growing.

That responsible approach is a direct reflection of the farm's values, and it is one reason the color stays vivid and the aroma stays clean and fresh.

Crafted from the First Spring Harvest

Only the earliest spring leaves are selected for this matcha, harvested at their peak when amino acids such as L-theanine are highest. After shading, the leaves are processed into tencha and stone-milled slowly to preserve their delicate structure.

This traditional method creates a matcha that whisks easily with hot water (not boiling), producing a smooth, frothy bowl with a rich, full-bodied flavor.

Preparation and Enjoyment

For a traditional thin tea, whisk 1–2 grams of matcha with hot water (around 70–80°C, not boiling) until smooth and frothy. For thick koicha, use more powder and less water and blend to a smooth paste.

Thanks to its creamy body and rich umami, Gokou also makes an excellent matcha latte with milk or oat milk.

Limited Seasonal Production

Because single-cultivar Gokou is grown and processed in small quantities, only a limited amount is produced each spring. Once the seasonal batch sells through, it returns with the next first harvest.

Frequently Asked Questions

Common questions about this Gokou matcha

How do I prepare this matcha?

For a traditional bowl (usucha), sift 1–2 grams of matcha into a warm chawan, add about 60–70 ml of hot water (not boiling — around 75–80°C / 165–175°F), and whisk briskly with a chasen in a "W" or "M" motion until a fine layer of foam forms on the surface.

Avoid boiling water. Heat above 85°C extracts excess tannins and dulls the flavor. For best results, let kettle water rest for 60–90 seconds after boiling before pouring.

What's the difference between ceremonial and culinary grade?

Ceremonial grade matcha is made from the youngest, most tender first-harvest leaves, stone-milled slowly to preserve aroma and texture. It is intended for drinking on its own, whisked with water, where its full character is on display.

Culinary grade matcha typically uses later harvests and is designed to stand up to other ingredients — milk, sugar, baked goods, ice cream — where a more robust, slightly bitter profile is desirable.

This Gokou is ceremonial grade. It is rich and full-bodied enough for thick koicha as well as thin usucha, and its creamy body also performs well in high-quality lattes.

Is this matcha organic?

This Gokou matcha is grown pesticide-free — without synthetic pesticides or herbicides — on a family farm in Wazuka, Kyoto. It is not, however, JAS-certified organic. Under JAS, certification is granted field by field, and this particular Gokou is not part of the farm's certified-organic range.

If you specifically want certified organic matcha, we also carry JAS-certified organic single-cultivar matcha from the same farm — get in touch and we'll point you to it.

How long does this matcha last after opening?

For best flavor and color, use within 1–2 months after opening, kept refrigerated in the sealed tin.

Matcha is light- and oxygen-sensitive. Once opened, oxidation begins immediately and slowly dulls both the bright green color and the fresh, vegetal aroma. Refrigeration slows this process significantly.

Before opening, an unopened tin stays fresh for around 12 months from the harvest date when stored cool and dark. Each batch carries a best-before date on the packaging.

Can I use this matcha in lattes?

Yes. While Gokou is made for ceremonial preparation, its creamy body and rich umami make it especially well-suited to high-quality lattes — both with dairy milk and with oat milk in particular.

For a latte, whisk 1.5–2 grams of matcha with a small amount of hot water to make a smooth paste first, then add warmed milk on top. This prevents clumping and preserves the color.

That said, if you primarily drink matcha lattes daily, a culinary-grade matcha may be a more economical choice. We carry both — get in touch if you'd like a recommendation.

What does "single-cultivar" actually mean?

Most commercial matcha is a blend — leaves from multiple cultivars combined to create a consistent house flavor profile year after year. Blending is a craft in its own right, but it averages out the distinctive character of individual cultivars.

Single-cultivar matcha uses leaves from one specific tea variety — in this case, Gokou. The resulting flavor is more distinctly the cultivar's own: rich, full-bodied, and umami-forward, with the creamy depth Gokou is known for.

Single-cultivar matcha is less common in Uji because it requires the farm and producer to manage harvests separately rather than combining stocks. It rewards the extra care with clearer character in the bowl.

Why is this matcha produced in limited quantities?

Three reasons.

First, this matcha comes from a single 160-year-old family farm in Wazuka — not a regional cooperative. The farm's total annual yield is small by industry standards.

Second, it uses only the first spring harvest (ichibancha). Later harvests from the same fields produce different teas; this matcha is not made from them.

Third, it is single-cultivar Gokou, which makes up only a small portion of Uji's matcha production and must be managed separately rather than blended into larger stocks.

When a seasonal batch sells through, we wait until the next spring. There is no way to accelerate the cycle without compromising what makes this matcha what it is.

Is matcha caffeinated?

Yes. Matcha contains caffeine — roughly 30–70 mg per gram of powder, depending on the cultivar and harvest. A standard bowl made with 1–2 grams therefore contains somewhere between 30 mg and 140 mg of caffeine.

For comparison, a typical cup of brewed coffee contains around 80–100 mg, and a cup of green tea around 25–30 mg.

Matcha's caffeine is generally experienced differently from coffee's, because matcha also contains L-theanine, an amino acid that promotes a calmer, more sustained kind of alertness. Many people who find coffee jittery find matcha smoother — though sensitivities vary, and we always recommend listening to your own response.
