Description

Technical Field

[0001] The invention relates to the technical field of tea processing, in particular to a preparation process of white-leaf Maofeng tea. Background Art

[0002] Baiye No.1 Maofeng is carefully selected from high-quality fresh leaves of Baiye No.1 tea trees and processed by our company's unique technology. It has a beautiful appearance, unique aroma, fresh and mellow taste, bright soup color, and even leaf bottom. It is a high-quality tea. The tea leaves are tight and even, emerald green, with white hairs, plump buds and leaves, and pine needle-shaped. It is rich in theanine, tender and lasting fragrance, accompanied by fresh floral and fruity fragrance, and the fragrance is quiet and far-reaching, intoxicating. The taste is fresh and mellow, the aftertaste is long, the tea soup is smooth, the taste is rich and harmonious, and you can feel the fresh sweetness at first, and then the aftertaste is long-lasting. The soup color is bright green, clear and transparent, as crystal as jade. The leaf bottom is bright green, the buds are complete, soft and elastic, showing the good quality of high-quality tea.

[0003] Baiye No. 1 tea tree is a rare tea tree variety. Its tea leaves are rich in substances and have unique quality and flavor. Baiye No. 1 tea tree has extremely high requirements for the growth environment. It usually grows in the mountains at an altitude of 800-1100 meters in our county. It is an area with superior ecological environment and no pollution. The yield is relatively small, so it is more precious. Baiye No. 1 is a rare albino variant tea tree variety. It is a low-temperature sensitive tea. Its threshold is about 23℃. The picking time is strict. The tender buds and leaves that sprout before Qingming Festival every year are jade white. After Grain Rain, they gradually turn into white and green leaves. After the summer solstice, the buds and leaves return to full green. In the past, Baiye No. 1 only picked one bud and one leaf, and the picking period was about 20 days before Qingming Festival. Through detailed analysis of fresh leaves in different seasons, different growth stages, and different altitudes, the specific time point most suitable for picking Baimaofeng tea leaves is determined to ensure that the quality of fresh leaves and the substances contained are in the best state. The quality of tea can be guaranteed through special processing technology and careful operation by experienced tea makers.

[0004] Drinking Baiye No. 1 Maofeng is not only a taste enjoyment, but also a spiritual cleansing. In the busy life, brewing a cup of Baiye No. 1 Maofeng, watching the tea leaves expand in the cup, smelling the rising tea fragrance, as if you are in the tranquil nature, the inner fatigue and irritability gradually dissipate.

[0005] Take a sip of tea, feel the fresh taste spreading on the tip of your tongue, and your thoughts will become clear and calm. At this moment, time seems to stand still, and your mind gets a moment of peace and relaxation.

[0006] Baiye No.1 Maofeng Tea not only brings you satisfaction in taste, but also a pursuit of quality of life and a yearning for inner peace. It allows us to find a piece of pure land of our own in the noisy world and savor the beauty and true meaning of life.

[0007] Tea craft refers to the methods and techniques of making fresh leaves into drinkable tea through a series of processing processes. Different types of tea have different process flows, which may include picking, withering, rolling, fermentation, drying and other steps. Green tea is withering immediately after picking fresh leaves to prevent the activity of enzymes in the tea leaves, and then rolling, frying or steaming to keep the green color of the tea leaves. Finally, the tea leaves are dried to keep them dry.
