Usucha

(Matcha) Often used in contrast with O-Koicha, Usucha (commonly O-Usu in Japan) literally means “mild tea” in Japanese. This is the most common form that Matcha takes when consumed in everyday life. Our Fine Matcha and Extra Fine Matcha are particularly well suited for the creation of Usucha. Many gourmet restaurants in Japan, especially those serving traditional Kyoto cuisine, present Usucha to customers. In most scenarios, Usucha and Matcha are practically synonymous, except where it is noted that one is being served O-Koicha.  (For more specific information on the preparation of Matcha, please click here.)

Wagashi

Wagashi are traditional Japanese pastries that accompany the Japanese Tea Ceremony, but are also regularly consumed with tea for any occasion. Common components of Wagashi include sweetened Mochi and red bean paste.

Umami

First defined over 100 years ago, Umami has become known as the fifth taste, the other four being sweetness, sourness, saltiness, and bitterness. The sensation of Umami comes from food rich in glutamates, such as Japanese tea. The taste of Umami itself is hard to describe, but it is a highly desirable component in tea, given a proper proportion. Tea considered to have a heightened presence of the Umami flavor is often sought. It is also sometimes said that the antithesis of Umami is bitterness, but this may be an oversimplification, given that a balance of Umami and astringency creates favorable teas, complex and stimulating. Truth be told, few Western dishes contain a noticeable amount of this pleasant flavor, and as a result, it may be hard to discern the Umami taste from a salty-sweet taste. However, please accept our assurance that given time, Umami can be experienced and enjoyed by everyone.

Ujicha

Ujicha cannot be grown just anywhere: in addition to the proximity to Lake Biwa, the hilly terrains of the Kyoto, Shiga, Nara, and Mie prefectures create region-specific qualities of the land and atmosphere (Terroir) prime for the cultivation of exquisite teas. Furthermore, Ujicha must be produced according to the traditional methods first developed in Uji. The Uji methods entail supreme quality, though they are labor intensive and require great skill. For tea-savvy Japanese, Ujicha brings to mind a quality of tea unable to be cultivated elsewhere. In addition, the area allows for Matcha, Gyokuro,  Kabusecha,  Sencha,  and Houjicha cultivation and production. Nowhere else in Japan is such a wide variety of tea able to be made.

Uji

Famous for being the city whose temple is on the ¥10,000 bill and the ¥10 coin, Uji is also renowned domestically as the center of high quality tea production. The proximity to Lake Biwa (Japan’s largest lake) provides a Terroir that is perfectly suited for tea farming, as underground streams carry nutrients into the soil. The small city is located south of Kyoto city. In ancient times, Uji acted as a retreat for the nobility situated in what is now Kyoto, who wished to adjourn from courtly turmoil. As early as the 12th century, tea began to be cultivated in the area.

Terroir

This term of French origin is used to describe aspects of various naturally occurring elements uncontrolled by human beings, that influence a tea plant during its growth. Climate, geography, richness of the soil, even altitude, can affect the physical properties of the plant, and therefore the specific tastes it will provide. The concept of Terroir is most frequently used in the West in regards to the conditions that affect the taste of a wine. Teas from a single field (see the definition of non-blended tea) embody the elements of Terroir specific to the field of its origin.  Uji‘s Terroir is perfectly suited for the production of tea, much like the Bordeaux region of France is suited for the production of wine.

Tencha

Like Gyokuro and Kabusecha, the Tencha quality of leaf is grown in a shaded environment for a period of time. High quality Tencha is characterized by a brilliant green leaf, possessing heavy flavors of Umami and very little astringency. Tencha is rarely consumed as a tea, for it has not undergone the final process required to make it infusible. Instead, it is most frequently ground into Matcha powder, which is then mixed with water for consumption. It can also be used as a flavoring agent in high-end gourmet kitchens.

Sencha

Sencha tea is the most common form of tea in Japan, and the most widely consumed. In contrast to Gyokuro and Kabusecha, Sencha remains in direct sunlight for the duration of its growth. Photosynthesis is simply allowed to take place as Nature dictates. Photosynthesis provokes the transformation of theanine, responsible for the Umami taste, into catechin, responsible for an astringent taste. If properly prepared, Sencha strikes a perfect balance between this sweetness and bitterness, and thus it maintains unrivaled popularity as Japan’s favorite tea. Rishouen offers Sencha of exceptionally high grades, manufactured from silky, young tea shoots known as Mirume in Japanese. (For specific instructions on how best to infuse Sencha, click here.)

O-Koicha

(Matcha) The word O-Koicha in Japanese literally means “strong tea”. The tea most frequently prepared in the Japanese Tea Ceremony, O-Koicha is made with around twice as much Matcha powder than ordinary Matcha tea consumed in an everyday manner, known as Usucha. However, for O-Koicha preparation, a higher quality Matcha is required, at least equivalent to our Quality ranked Matcha. Higher ranked Matcha powders can be used at higher concentrations without being overpowering and unbalanced in taste. Therefore the higher the quality of Matcha,  the stronger the tea can be made without an undesirable impact on the taste. The effect of consuming O-Koicha plays a key part in the Japanese Tea Ceremony, as the high caffeine content creates alertness, and the pleasurable flavor of Umami stimulates areas of the brain responsible for memorization and focus. This state of alert tranquility is perfect for maximizing one’s abilities, without the jittery and wired feeling that may result from consuming other common liquid stimulants.

Ochazuke

Ochazuke is a very simple Japanese dish, prepared by pouring tea over rice. Traditionally, a Sencha with Karigane or Genmaicha is often used, accompanied with pressed seaweed flakes known as Nori, filet of salmon, or preserved apricot-like fruit called Umeboshi.
