Matcha

Matcha is a finely ground powder of green tea specially processed from shade-grown tea leaves. Shade growing gives matcha its characteristic bright green color and strong umami flavor. Matcha is typically consumed suspended in hot water.

Definition
Strict definitions of matcha are given by the International Organization for Standardization, ISO 20715:2023 "Tea — Classification of tea types", and the Japanese food labeling standard defined by . Both definitions require that matcha must be: • made from Camellia sinensis var. sinensis (Chinese, small-leaf tea) • grown in the shade • steamed and dried without being rolled • ground to a fine powder The Japanese food labeling standard requires the tea leaves to be shaded for 2–3 weeks before harvesting using covering materials such as yoshizu, komo, or cheesecloth. Tea leaves after processing the first three steps are called in this standard. ISO 20715:2023 allows matcha to be made from tender leaves, buds, or shoots, but Japanese food labeling standard allows it to be made only from leaves. Inexpensive green tea, , made by crushing non-shade grown tea leaves, is sometimes sold under the name of "matcha" although it does not satisfy the above definitions. The cheaper alternative is used to flavor and dye foods. == History ==
History
Japan The earliest documented reference to tea in Japan appears in the 9th century, in an entry in the concerning the Buddhist monk , who is believed to have brought tea back from China. According to the entry, Eichū personally prepared and served to Emperor Saga during an imperial excursion to Karasaki (in present-day Shiga Prefecture) in 815. Powdered tea first arrived in Japan around the 12th century. It can be traced back to Tang dynasty China, where Chinese Zen (Chan) monks were the first to grind bricks of tea into fine powder with a pestle and mortar. Japanese monk Myoan Eisai travelled to China around the late 1180s, and encountered a drink at the temples there that the Chinese called as "mo cha", which involved pouring hot water over powdered tea and whisking it with a bamboo whisk. Eisai was credited to have brought back this Song dynasty style of tea preparation to Japan. In China, this practise of mo cha however faded over the next centuries during the Ming dynasty, but it continued in Japan, and become a key part of Japanese Zen Buddhist culture. This method is believed to have been introduced to Japan at that time. However, a major difference is that modern matcha production omits the long roasting process, apart from drying for approximately 30 minutes. At the time, the tea was a brownish-black lump, rather than the bright green powder of modern matcha. It is thought that this lump tea was ground into powder and consumed in a manner similar to modern matcha. In Japan, illustrations of "matcha jars" (, in this case referring to tea caddies) appear in the Kundaikan sōchōki (, literally "Record of Appraising Objects for the Lord’s Viewing Stand"), a Muromachi-period manual on art connoisseurship and interior decoration compiled by the art connoisseurs Nōami and Sōami for the shogun Ashikaga Yoshimasa. The "Nōami-bon" (1476) and "Sōami-bon" (1511) The characters for matcha () also appear in the Japanese dictionary Unpo Iroha Shū (1548), compiled during the Muromachi period. The Book of Agriculture (1313) by Wang Zhen ( 1290–1333) of the Yuan dynasty includes the terms () and (). One theory suggests that these words were adopted and transformed into the term "matcha" in Japan. However, as this book was published about a century after Eisai, no documentary evidence confirms whether these terms were introduced to Japan or evolved into "matcha" by the 16th century. Moreover, whether read as matcha or suricha, the term literally means "tea that has been ground". In contrast, the terms (mòchá) and (mòzichá) mean "tea reduced to powder," and thus differ not only in characters and pronunciation, but also in meaning. Eisai's disciple, the monk Myōe (1173–1232), received a tea urn containing seeds from Eisai and established a tea plantation in Togano'o, Kyoto, by sowing them there. During the Kamakura period (1185–1333), Togano'o tea was known as , while teas from other regions were referred to as . During the Muromachi period (1336–1573), tea spread among the general public. Among the elite, it became fashionable to drink tea using expensive Chinese ceramics known as . In the 16th century, however, tea masters such as Murata Jukō and Sen no Rikyū emphasized simplicity, giving rise to the Japanese tea ceremony. This practice prioritized introspection over ostentation and came to favor simple utensils. The wabi-sabi aesthetic, which finds beauty in modesty, simplicity, and imperfection, became closely associated with the tea ceremony. It was long believed that the practice of growing tea plants under shade by covering them with straw or reeds began in Japan in the late 16th century. For example, the Portuguese missionary João Rodrigues Tçuzu, who arrived in Japan in 1577, wrote about shaded cultivation in his 1604 work, History of the Japanese Church (). However, recent soil analyses of Uji tea plantations suggest that the practice began in the first half of the 15th century at the latest. This technique, originally intended to protect tea sprouts from frost damage, led to the development of a unique Japanese matcha () that was bright green and had a distinctive aroma and flavor. By limiting exposure to sunlight, photosynthesis in the leaves is inhibited, preventing the conversion of theanine—a component responsible for umami—into tannins, which cause bitterness and astringency. As a result, the tea leaves retain a higher umami content. Shaded cultivation also increases the concentration of chlorophyll in the leaves, resulting in a vibrant green color. Until then, matcha introduced from China was brown in color—hence the Japanese word for "brown", (), literally means "tea color". Traditions depicting tea picking in Uji, Kyoto. The painting was made by Hiroshige III (1842–1894). Since the Muromachi period, the term referred to tea manufacturers and sellers. During the Edo period (1603–1867), it came to refer specifically to the of Uji, Kyoto, whose status was guaranteed by the Tokugawa shogunate. Uji tea masters were divided into three ranks: , , and . They were permitted to use their family names and carry swords like samurai. They dealt exclusively with the shogun, the imperial court, and feudal lords, and did not sell tea to commoners. According to one theory, the name Baba Mukashi was bestowed by Ieyasu himself. Other well-known brands included and , both of which were also presented to the shogun. and were also well-known. At the time, matcha was shipped in tea jars filled with tencha (unground leaf tea), which was later ground into powder using a tea grinder. The event of transporting tea jars from Uji to Edo (now Tokyo) for presentation to the shogun was called the , and even feudal lords were required to stand aside when the procession passed. The tradition continued from 1633 until 1866, near the end of the Edo period. The establishment of research institutions, such as the , further contributed to the modernization and quality improvement of matcha production. Throughout the 20th century, matcha remained central to the practice of the Japanese tea ceremony, preserved by major tea schools such as Urasenke and Omotesenke. Its role in cultural education expanded through school tea ceremony clubs and public workshops, maintaining its status as a traditional beverage in Japan. It has been adopted into various products such as matcha lattes, desserts, and confections. The term "matcha" has become widely recognized globally, and Japanese producers have promoted exports of high-quality matcha under regional brands, particularly from Uji, Nishio, and Shizuoka Prefecture. As demand grows, concerns have also emerged about maintaining quality standards and ensuring the authenticity of Japanese matcha. Both the public and private sectors are working to preserve traditional production methods and promote environmentally sustainable cultivation practices. In recent years, some Kyoto-based tea companies have implemented purchase limits on premium matcha due to supply constraints, particularly of first-flush matcha, which was historically reserved for tea ceremonies but is now widely consumed overseas. The labor-intensive nature of production, limited grinding capacity, and a shrinking number of tea farmers have added further strain to the supply chain. In response, both government and industry stakeholders are exploring policy reforms, subsidies, and regional diversification to protect traditional cultivation and meet ongoing international demand. In 2025, Matcha became more popular in Thailand, and its international popularity was seen as part of a trend for "affordable luxury" products. China Powdered and compressed teas Powdered tea originated in China during the Tang dynasty (618–907) where tea leaves were pounded and then milled into fine powder before being shaped into "cakes". The Classic of Tea, written by Chinese tea master Lu Yu roughly between 760 to 762 CE, had documented the practise of steeping powdered tea in hot water. This involved first roasting compressed tea over a fire and then grinding it in a wooden grinder called a niǎn (, Japanese: yagen), boiling water in a pot, adding salt once it comes to a boil, then adding the tea powder to the boiling water and boiling it until it began to foam. The tea was also sometimes mixed with green onions, ginger, jujubes, mandarin orange peels, Tetradium ruticarpum, and mint. The beverage was prepared by whipping the tea powder with hot water in a bowl. Although the term "matcha" () was not yet used, the practice of preparing powdered tea with a tea whisk is believed to have originated in China no later than the 11th century. The most famous references to powdered tea are Cai Xiang's Record of Tea (1049–1053) and Emperor Huizong's Treatise on Tea (1107), both written during the Song dynasty (960–1279). These documents describe the preparation of high-grade compressed tea, such as Lóngfèng Tuánchá (, ). The tea was ground into powder using a metal niǎn, then sifted. The powder was poured into a tea bowl, hot water was added, and the mixture was whisked. According to the Record of Tea, the finer the sieve, the more the tea would float; the coarser the sieve, the more it would sink. This suggests that the powder particles were larger than those of modern matcha. Tea ceremonies at Kennin-ji in Kyoto and Engaku-ji in Kamakura are thought to preserve traditions from the Song dynasty. The lump tea presented to the emperor was mixed with borneol, a strongly aromatic substance, and coated with oily flavorings to give it a glossy surface—so much so that the tea's original aroma was lost. Cai Xiang criticized such processing. Declining usage of compressed tea The complex manufacturing process of lump tea during the Song dynasty required significant labor and expense, and even the slightest error could result in failure. As a result, it was costly and inaccessible to the common people. During the Tang dynasty, "bitter when sipped and sweet when swallowed" (The Classic of Tea) was regarded as the ideal taste of tea. However, in the Song dynasty, this ideal was deliberately replaced with four desirable qualities: "aroma, sweetness, richness, and smoothness" (Treatise on Tea). With the prohibition of compressed tea, the powdered tea associated with it also fell into disuse in China. In Japan, however, a tradition of powdered tea preparation was preserved. Through innovations such as shade cultivation of tea leaves (覆下栽培) and stone-milling, Japan eventually developed what is now known as matcha, which over time was deeply shaped by Japanese aesthetics and cultural principles. Some historians have pointed out that, as the Ming dynasty emphasized agriculture and held a strong military ethos—and since the Hongwu Emperor himself had risen from the lowest social strata—he may have viewed the elaborate and refined nature of compressed tea with disdain. United States Explosion in 2000s Matcha likely first entered the U.S. market through Japanese grocery stores in cities with large Japanese populations, particularly Los Angeles and San Francisco. While initially available through specialty importers and Japanese markets, matcha remained relatively obscure in mainstream American culture for decades. The powdered green tea began gaining significant traction in the early 2000s when specialty brands started targeting health food retailers including Whole Foods Market. The beverage's photogenic bright green color proved particularly well-suited to social media platforms like Instagram and TikTok, helping it gain viral popularity among wellness enthusiasts and influencers. Major coffee chains including Starbucks and Dunkin' Donuts subsequently added matcha lattes and other matcha-based drinks to their permanent menus, cementing its place in American café culture, with countless U.S.-based brands popping up, including matcha-focused brands like Jade Leaf, Kettl, Shinzo Matcha, and Encha Matcha, and lifestyle brands offering matcha options like Chamberlain Coffee. Controversy and shortage Perhaps controversially, because of the increased demand, a matcha shortage ensued in Japan. Major Japanese producers including Marukyu Koyamaen and Ippodo announced limited availability or suspended sales of matcha products in late 2024, with the 2025 harvest yielding 20% less than the previous year. The shortage was further complicated when the United States imposed new 15% tariffs on Japanese imports in August 2025, compounding already-doubled wholesale prices and raising ethical questions about whether Western consumer trends were placing unsustainable pressure on traditional Japanese tea farming practices. == Characteristics ==
Characteristics
The characteristics of matcha are as follows: • Color: bright green, might be dark green depending on which leaves are used • Flavor: strong umami flavor • Aroma: unique , like green laver The characteristic bright green color is due to the increased chloroplasts that the plants need to collect more light in the shade. The aroma is due to the matcha's dimethyl sulfide content. and the matcha form is particularly rich in umami flavor with twice the amino acids (the source of umami) as sencha green tea. The growing of , which serves as the material for producing matcha, relies on the plant being grown in shade, therefore, not breaking down the content of theanine on the leaves. Shading increases the amount of caffeine and total free amino acids but also reduces the accumulation of catechins in leaves. Like all tea, matcha naturally contains oxalates. Research, published in Soil Science and Plant Nutrition journal, found that shading, a cultivation method that is used in the production of matcha, may increase oxalate concentration. The study further suggests that oxalate concentration in matcha may be higher than in unshaded teas like sencha. == Production ==
Production
Japan The majority of matcha is produced in Japan, where it is highly regarded as part of the tea ceremony (chanoyu (茶の湯)) as well as used in sweets, baking, and confections. China and Vietnam also produce some matcha intended for export. This is a more recent modern development, and their production methods may differ significantly from the traditional Japanese method. In the past, the prepared tea leaves would be ground by hand in a single-purpose stone mill, which produces a finer grind than those used for grain and pulse flours, but today matcha producers use mechanically turned stone mills – the slow speed of grinding and use of cool grinding rooms prevents heating the tea and deteriorating the quality. == Preparation ==
Preparation
Matcha is typically consumed by mixing with hot water. There are two kinds of matcha tea – and . Koicha is made by higher-grade matcha and less hot water with a lower temperature than for usucha. Usucha is foamed to reduce astringency while koicha is not foamed. Specifically, koicha is made from matcha and of hot water at , and usucha is made with half matcha in twice the volume of hot water at . Due to the above differences, koicha has more of an original taste of matcha than usucha. while drinking usucha is considered as a sub-part of it. In the ceremonies, matcha is stored and made using a special teaware called chaki. Specifically, matcha for koicha and usucha are stored in special containers, and , respectively. Before use, the matcha can be sifted through a sieve to reduce clumps. Matcha is scooped out from these containers by , a traditional Japanese spoon. Matcha and hot water are then put in a , the bowl, and stirred with , a whisk usually made from bamboo. It is drunk from the chawan. One drinks matcha after finishing (not during) eating sweets to allow a prolonged taste of the matcha.

Difference from other Japanese green tea
There are several types of powdered Japanese green tea and the differences are as follows. All of the above ones are made from Camellia sinensis var. sinensis (Chinese, small-leaf tea). == Other uses ==
Other uses
Matcha (or funmatsucha under the name of "matcha") is used in castella, manjū, and monaka; as a topping for shaved ice (kakigōri); mixed with milk and sugar as a drink; and mixed with salt and used to flavor tempura in a mixture known as matcha-jio. It is also used as flavoring in many Western-style chocolates, candy, and desserts, such as cakes and pastries, including Swiss rolls and cheesecake, cookies, chou à la crème, castella, pudding, mousse, and green tea ice cream. Matcha frozen yogurt is sold in shops and can be made at home using Greek yogurt. The snacks Pocky and Kit Kat have matcha-flavoured versions in Japan. It may also be mixed into other forms of tea. For example, it is added to genmaicha to form matcha-iri genmaicha (literally, roasted brown rice and green tea with added matcha). The use of matcha in modern drinks has also spread to North American cafés, such as Starbucks, which introduced "green tea lattes" and other matcha-flavored drinks after they became successful in their Japanese store locations. As in Japan, it has become integrated into matcha lattes, iced drinks, milkshakes, and smoothies.
