Tangerine scented ancient tree black tea and manufacturing method thereof

Abstract

The invention discloses a manufacturing method of tangerine scented ancient tree black tea. The manufacturing method is characterized by including the step of subjecting Fengqing big-leaf tea serving as a raw material to selecting, withering, rolling, freezing, fermenting and drying. By the step of freezing before fermenting, loss of beneficial components can be reduced. By raw material selection and processing process control, flavors of tea polyphenol, amino acids and some carbohydrates in tea can be combined. Obtained ancient tree black tea leaves are fleshier than Yunnan black tea leaves, and plump and compact strips, glossiness in color, thick tea flavor, honey sweetness in taste, transparency and brightness in liquor color, high throat comfort, evident effects of sweetness lingering and saliva secretion promoting and toughness of infused tea stems are realized.
