Japanese green tea

„Gyokuro (玉露, Jade Dew) - Gyokuro is a fine and expensive type that differs from Sencha (煎茶) in that it is grown under the shade rather than the full sun for approximately 20 days. The name "Gyokuro" translates as "jade dew" and refers to the pale green color of the infusion. The shading causes the amino acids (Theanine) and caffeine in the tea leaves to increase, while catechins (the source of bitterness in tea, along with caffeine) decreases, giving rise to a sweet taste. The tea also has a distinct aroma.“

„A book written in the Tang Dynasty of China is considered one of the most important in the history of green tea. The book was written by Lu Yu and is called the "Tea Classic" or "Cha Jing". It was written between 600 and 900 AD and spoke about exactly how and where one could enjoy a fine cup of green tea.“
