Types of Japanese tea

In Tea production,what is usually called fermentation is actually oxidation.
Processing is different but it is made from one and the same tea plant.

The fermentation of tea leaves involve the work of oxidation enzymes in the fresh leaves and it differs from the fermentation that occurs when alcohol or cheese is produced which involves the active participation of microorganisms.
Green tea,Oolong tea and Black tea are all made from the same tea plant,and they are different only in the way they are produced.

Blume: What is “deep steamed green tea”?

Sencha is divided into ordinary (steamed) green tea and deep steamed green tea according to the degree of steaming. The deep-steamed tea has long steaming time, so the tea leaves become finely broken and it looks like powdery appearance. The astringent taste is suppressed, the taste become mellow and strong, and the color of the water becomes deep green. Tea leaves are fine and it is easy to clog the teapot, so we recommend a teapot for deep steamed Sencha.
