Among the types of Japanese green tea prepared by decoction, "sencha" is distinguished from such specific types as gyokuro and bancha. It is the most popular tea in Japan, and represents about 80 percent of the tea produced in Japan. The flavor depends upon the season and place where it is produced, but it is considered that the most delicious sencha is that from the first flush of the year, the shincha "new tea." The shincha season, depending upon the region of the plantation, is from early April to late May (around the 88th day after the spring equinox). It is considered that the ideal color of the sencha beverage is a greenish golden color. Depending upon the temperature of the water in which it is decocted, the flavor will be different, and this also is the appeal of sencha. With relatively not too hot water, it is relatively mellow; with hot water, it is more astringent. Unground tea was brought from China after matcha (抹茶, powdered green tea). Some varieties expand when steeped to resemble leaf vegetable greens in smell, appearance, and taste. Sencha in Japan is drunk hot in the cooler months and usually chilled in the summer months.
