Yellow tea may be viewed as a green tea with a special, prolonged process of drying. It has deeper taste, more yellowish color, and a pronounced fragrance. The tea is rare today, but once it was a popular drink amongst common people.
Greenish tea or oolong tea is skilfully rolled and oxidized after picking, allowing the essential tea ingredients to react with the air. This process turns the leaf to darker green and produces distinctive fragrances before heat is applied to set the taste. The resulting tea can be anywhere between a green and a red tea. Oolongs can be recognized by flavour that ranges from highly floral, intensely fruity, to mildly roasted with honey nuances. Patience and care must be taken to make and to prepare the tea, tea connoisseurs take it to the level of an art, and call it kung-fu tea.
