There are several harvests (a.k.a. flushes) of tea leaf each year. 'Ban-cha' is a traditional, daily-use, Japanese green tea variety that is made from mature leaves, plucked in the summer or autumn, while "Mat-cha" and "Sen-cha" are varieties made from young, tender leaves, plucked in the spring. Tea leaf is cultivated throughout Asia and each estate produces tea with its own unique characteristics.
