Kettl and Jiro Katahira's Ryogochi Okuyutaka

A Brooklyn tea company with an office in Fukuoka, and a Shizuoka mountain farmer who grows more than twenty cultivars.

The short answer

Ryogochi Okuyutaka is a single cultivar matcha from Jiro Katahira, a farmer in the Ryogochi mountains of Shizuoka who grows over 22 tea cultivars, sold by Kettl, the tea company Zach and Minami started in Brooklyn and now in its 15th year.

Kettl names the producer, area and year on every matcha, and recommends this one, 2026 production in a 20 g tin, as usucha or sparkling matcha.

Kettl is one of the few American tea companies with its own office in Japan. Its story page says Zach and his wife Minami started it, that it is now in its 15th year, and that tea is sent by air from its Fukuoka office straight to its Brooklyn warehouse. It runs shops in Greenpoint, including a dedicated matcha shop on Norman Avenue, and in Los Feliz in Los Angeles. Kettl describes its catalogue as the most diverse of Japanese tea available outside Japan. What makes it useful to anyone learning matcha is how much it tells you. Every matcha page gives a producer, a production area and a production year.

Jiro Katahira and Ryogochi

Ryogochi is a mountain tea area in Shizuoka, far up the valleys from the big flat sencha fields near the coast. Kettl's Ryogochi Okuyutaka page introduces Jiro Katahira, who grows over 22 distinct cultivars, and calls this matcha the first release from his new project. Most tea farms grow a few cultivars at most. A grower with more than twenty is the kind of farmer who makes single cultivar matcha interesting, because the same hillside, the same hands and the same year can show what each plant does.

Okuyutaka itself is an uncommon choice for matcha. Kettl's page says it was registered in 1983 by the Kanaya tea research centre in Shizuoka. Kettl lists the production year as 2026, sells it in 20 gram tins at $40, and recommends it as usucha or as sparkling matcha, which says something about its brightness. A sibling, Ryogochi Okumidori from the same project, was out of stock when we read the page.

The Furukawas in Gokasho

Kettl's other headline producers are Yoshitsugu and Mizuho Furukawa in Gokasho, one of the old tea villages of Uji. Their Gokasho Organic Uji Hikari uses Uji Hikari, a cultivar named for the area, and Kettl notes that in 2025 their teas placed first overall at both the regional Kansai tea fair and the national tea fair. For koicha Kettl gives 4 grams of matcha to 30 to 35 ml of water at about 180°F.

Making the Okuyutaka

For usucha, Kettl gives 2 grams with 65 ml of water at about 180°F. For a cold version, 2 grams shaken in a bottle with 200 ml of cold filtered water. That cold method is a good way to taste a bright cultivar, because cold water keeps bitterness down and lets the fresh, green notes come forward. More on the plant itself is in our piece on what single cultivar means on a tin.
