Problems solved by technology

[0003] The old tree white tea is a unique white tea. The general green tea preparation process is withering and drying. In the process of processing, due to factors such as raw materials, craftsmanship and human factors, the old tree white tea prepared by the traditional method has aroma. Insufficient coordination and durability, poor potency, poor sweetness of tea soup, etc., the quality is uneven, and it is difficult to meet the needs of daily consumption
Moreover, there are few studies on the preparation method of old tree white tea at present.
