What is the colour between while and black? Green.
Yes, in the world of tea, white tea are unprocessed tea that is picked while the leaf is more like bud. Green tea is unprocessed tea leaf. And following on, black tea is processed or fermented tea leaf.

Most green tea are produced in China or east Asia. Hence, Ceylon green tea is something of an exception. It is grown in the highlands of Sri Lanka, in an area of 4 thousand square miles.
This Dilmah Ceylon green tea is nice. It is lightly fragrant, more than the normal black tea, but less than the Chinese green tea like the Longjing. Quite good.
Made in Sri Lanka. Bought from Singapore.
