Gyokuro Joshu by Marukyu Koyamaen is a high grade gyokuro with deep, jewel green leaves. The aroma is deep and intense with the sweet floral scent of jasmine. The first brew is savoury with deep vegetal and umami flavours. The mouthfeel is luxurious and smooth. Joshu is am elegant medium bodied gyokuro with more depth and complexity. Gyokuro tea (玉 露 or Jade Dew) is is the highest quality form of green tea that's cultivated in the same process as Tencha (used for matchas) and presented as rolled leaves. This tea is prized for its sweet and rich umami flavours and appreciated by tea connoiseurs for it rarity due to its labour intensive production method. Gyokuro can be brewed multiple times with the 2nd and 3rd infusions to draw out its deeper umami flavours as the savoury notes develop. Joshu has a similar profile to the full-bodied matchas in the ceremonial line. Enjoy Joshu in the mornings or as an afternoon tea with desserts that enhances its floral scent and creamy taste like shortbread biscuits, scones and tarts. As a savoury application, the umami and sweetness of gyokuro can be used for ochazuke (poured tea over rice)

About The Producer
Founded during the Genroku period (1688-1704), Marukyu Koyamaen has spent more than three centuries producing Japanese green tea from its home in Uji, Kyoto, a region long recognised as the historical centre of Japanese tea cultivation. Established by Kyujiro Koyama, the company has remained dedicated to the cultivation, procurement, refining and blending of tea across successive generations, combining traditional craftsmanship with continually evolving production methods.

Marukyu Koyamaen oversees every major stage of the process. Alongside tea cultivated on its own farms, the company works closely with carefully selected growers before refining and blending each tea to achieve its intended character. This integrated approach has remained central to the company's production for more than 300 years and continues across its matcha, gyokuro, sencha, hōjicha and other Japanese green teas.

Marukyu Koyamaen's commitment to tea production has been recognised through one of Japan's strongest records at the National Tea Competition, receiving numerous first-place awards across multiple tea categories over several decades. Today, the company continues to produce its teas from Uji, combining centuries of accumulated knowledge with modern production and quality control while remaining one of Japan's longest-established tea producers.

Marukyu Koyamaen's 丸久小山園 traces its origins to the Genroku period (1688-1704), when Kyujiro Koyama began cultivating and producing tea in Ogura, Uji, Kyoto. For more than three centuries, the Koyama family has remained dedicated to the production of Japanese green tea, with each generation building upon the knowledge, techniques and standards established by those before it.

From its home in Uji, Marukyu Koyamaen has developed as an integrated tea producer, combining tea cultivation, procurement, refining and blending under one organisation. Alongside tea grown on its own farms, the company works with carefully selected growers in Uji and other established tea-producing regions, allowing it to produce blends that remain consistent from harvest to harvest while reflecting the character expected of each tea.

Over the course of its history, Marukyu Koyamaen has earned one of Japan's strongest records at the National Tea Competition, receiving numerous first-place awards across different tea categories. These achievements reflect decades of refinement in cultivation, processing and blending, and have helped establish the producer as one of the most respected names in Japanese tea.

Today, Marukyu Koyamaen continues to produce matcha, gyokuro, sencha, hōjicha and other Japanese green teas from its base in Uji. While production methods have evolved alongside modern technology, the company remains focused on preserving the craftsmanship, consistency and regional character that have defined its teas for more than 300 years.

Ingredients: Green Tea Leaves

Preparation Method

  1. Brew hot water and allow to cool till 70℃~75℃.
  2. Preheat your tea cup by filling it with the 70ºC water to the 60% mark and allow this to cool to 60℃~65℃. To brew a pot, measure out multiple cups of water and set aside.
  3. Put Gyokuro tea leaves in the pot. For 3 servings, 3 full teaspoons of tea (about 7-8 g). For 5 servings, 4 full tea spoons (about 10-12 g).
  4. Once the water that's been set aside cools to 50℃~55℃, its ready for brewing. Fill the warm water back into the pot, and wait for 1.5 - 2 minutes for the first infusion. Finish off the first infusion before attempting further infusions.
  5. For a second infusion, use water of a little higher temperature than for the first (55℃~60℃) and let the tea draw for only 30 seconds before filling up to 70% it into the cups.
  6. For a third infusion, use water of even higher temperature than for the second and let the tea draw for only 15 seconds.
