Overview:
The sannen-bancha (三年番茶) which CHAMART introduces is made from aracha (unrefined tea leaves) of stems of fukamushicha (deep-steamed green tea) which was stored in the fridge for three years to ripen and improve the richness and mellowness of its flavor. Then, the leaves were roasted by a roasted machine with natural sands at around 180 to 220℃ for about 20 seconds.
The flavor of sannen-bancha is similar to hojicha, but it is different from hojicha. Sannen-bancha has a mild roasted flavor with a subtle acidity. The roasted flavor is not strong like hojicha.
The tea leaves and stems are stored and matured for three years, which reduces stimulatory components such as caffeine or tannins and makes a mellow flavor.
Sannen-bancha can be compared to a fine aged wine, and is especially enjoyable served in a wine glass.

The sannen-bancha is single origin and certified as JAS Organic and is produced in Kakegawa City, Shizuoka Prefecture.
The tea leaves of sannen-bancha are cultivated by the Chagusaba farming method which was recognized as a Globally Important Agricultural Heritage System (GIAHS) by the United Nations in 2013.*
This sannen-bancha is eco-friendly tea and CHAMART calls the sannen-bancha “CHAGUSABA tea”.

CHAMART introduces 1 grade (3B1) of Sannen-bancha. The variety of sannen-bancha is Yabukita

Variety: Yabukita
Yabukita is the most popular variety of tea plant in Japan. Yabukita is a well-balanced variety, with a high yield and has a strong umami flavor. Yabukita is suitable for any kind of green tea.

Producers of tea:
A family-run tea garden that manages the production of tea from cultivation through processing. The tea farmer’s teas have received awards at multiple national and international tea contests.
The philosophy of the tea farmers is respect for nature and cultivating tea. They do not want to destroy the ecosystem using agricultural chemicals. Thus, they don’t use any chemicals for their tea cultivation.

They mix Chagusa (grasses around the tea fields) and rice bran with soil and ferment them to make nutrient rich soil. Microscopic organisms work in the mixture and it becomes organic compost. The soil is put into their tea fields.

Production place: Kakegawa City, Shizuoka, Japan
Shizuoka Prefecture is a major tea production area of Japan, located in the center of the main island of Japan. Shizuoka Prefecture has a warm climate with many rivers and is often foggy. These conditions are suitable for tea cultivation.
Kakegawa City is one of the major tea production cities in Shizuoka Prefecture and is especially famous for fukamushicha. There is Mt. Awagatake with Chamonji (茶文字). The letter “茶” (tea) has been created by planting 1,000 Hinoki trees (Japanese cypress) on the slope of Mt. Awagatake. The dimensions of the letter “茶” (TEA) are about 130 x 130 meters. It is a symbol of Kakegawa City. The Chamonji was created with pine trees for advertising tea in 1932 first, but the trees were blighted by pine weevils. Then, the Chamonji was created with 1,000 Hinoki trees again in 1985.
There are many facilities related to tea such as tea museums, a tea-themed hotel, etc. in Shizuoka Prefecture.

*Shizuoka’s Chagusaba farming method (Traditional Tea-grass Integrated System in Shizuoka)
静冈的茶草场农耕法/靜岡的茶草場耕法
The Chagusaba farming method is a farming method traditionally practiced in Shizuoka Prefecture using grass mulch.  It is an example of circular agriculture that harmonizes humans’ relationship with nature to preserve the environment and protect biodiversity.
Shizuoka’s Chagusaba farming method, which is conducted in 4 cities and 1 town including Kakegawa City, has been recognized as a Globally Important Agricultural Heritage System (GIAHS) by the Food and Agriculture Organization of the United Nations (FAO) in 2013.*

Cha (茶) means tea, Gusa/Kusa (草) means grass, and Ba (場) means place. Chagusaba (茶草場) refers to the semi-natural grasslands around tea fields. The Chagusaba farming method makes use of natural resources by cutting pampas or bamboo grasses that grow around the tea fields and laying them in the furrows between the tea fields. These grasses used in the tea fields are called Chagusa (茶草).

The grasses laid in the furrows are fluffy and look like a Japanese futon (like a duvet). The Chagusa gradually breaks down to become compost. In addition, the laying of Chagusa makes it difficult for weeds to grow, and prevents moisture evaporation and the soil from being displaced by rainwater.

Maintain the environment and biodiversity
Tea farmers cut pampas or bamboo grasses in autumn and winter, dry them and cut them into smaller pieces. During the winter, tea farmers put the Chagusa into the tea fields. By cutting the tall pampas or bamboo grasses around the tea fields, small animals and plants are given access to sunlight, allowing them to thrive.

Drink LEAF TEA and Protect Nature
Grass mulch farming was once conducted all over Japan before. However, it is a burden on tea farmers and the market price of leaf tea isn’t stable today. Thus, the number of tea farmers who conduct grass mulch methods has been decreasing.
You can support the tea farmers by purchasing and drinking the tea cultivated by the Chagusaba farming method. Consequently, you will contribute to maintaining the environment and biodiversity.

GIAHS are traditional agroecosystems made up of communities that have lived in an intricate relationship with their territory across generations while adapting to changes in society and the environment. They are recognized by the Food and Agriculture Organization of the United Nations (FAO). Additionally, the systems are resilient, characterized by remarkable agrobiodiversity, traditional knowledge, invaluable cultures and landscapes, sustainably managed by farmers, herders, fisherfolk, and forest people in ways that contribute to their livelihoods and food security.
FAO has designated a GIAHS related to tea in 3 sites in China, 1 site in Japan and 1 site in South Korea.

*Tea leaves contain caffeine. The diuretic, stimulant and anticancer effects of caffeine intake are clinically recognized. On the other hand, excessive intake of caffeine may have a damaging effect on health. Especially, pregnant or breastfeeding women, and children should be careful with the amount of caffeine they intake.
