Yellow Tea: A Lightly Fermented, Island Grown Tea

The processing of yellow tea begins in the same way as Chinese green tea, except that the fixing of the leaves takes place under a covering of straw. This is followed by an extended "resting" period under cover during which some slight fermentation occurs. The tea is then delicately rolled into needles and dried. This process gives the leaf a green-yellow color and produces a golden-yellow liquor characterized by aromas with a dominant fruity, flowery note.
This tea is produced in only one place, on Jun Shan island (Jun Mountain) in Dongting Lake, Hunan province, China. The most prized of all is Jun Shan Yin Zhen (Jun Mountain Silver Needle), which consists only of bud. It's rarity and fineness mean that this quality of yellow tea sells for around $69 per 3.5 ounces (100 grams).
