What is the difference between black tea and green tea, and is there any difference between black te

Black tea: It is a fully fermented tea (fermentation degree is 80-90%), such as Keemun black tea, lychee black tea, etc. There are three main categories of black tea: small black tea, gongfu black tea and black broken tea.

Processing method: The green tea production process has gone through the process of finishing> rolling, > drying. When black tea is processed, it is not killed, but withered, so that the fresh leaves lose part of the water, and then rolled, and then fermented to oxidize the tea polyphenols contained in it and turn them into red compounds.

Tea water temperature: The control of tea water temperature depends on the tea. Green tea is generally brewed with boiling water of about 80 degrees, the water temperature is too high to destroy the vitamin C in the tea, and the caffeine is easy to precipitate, resulting in the tea soup turning yellow and the taste is bitter.

Drinking flower tea and black tea should be brewed with boiling water at 90 100 degrees, if the water temperature is low, the active ingredients in the tea are less precipitated, and the tea taste is light. Efficacy: Drinking green tea can soften blood vessels, reduce excessive blood lipids, prevent arteriosclerosis, and prevent and reduce the deposition of melanin in **.

Black tea has the effect of nourishing the stomach, diuretic, eliminating edema and strengthening myocardial function. Green tea, also known as unfermented tea; Tea is made from suitable tea tree shoots as raw materials, through typical processes such as killing, rolling, and drying. The color of its dry tea and the tea soup after brewing, and the bottom of the leaves are mainly green, hence the name.

2.The difference between the efficacy of black tea and green tea When black tea was first created, it was called "black tea". During the processing of black tea, a chemical reaction occurred, and the chemical composition in the fresh leaves changed greatly, and the tea polyphenols were reduced by more than 90%, resulting in new components of theaflavins and theaflavins. Black tea has strong antibacterial power, and rinsing your mouth with black tea can prevent colds caused by filtration viruses, prevent tooth decay and food poisoning, and reduce blood sugar levels and high blood pressure.

The characteristics of green tea retain more of the natural substances in the fresh leaves. Among them, tea polyphenols and caffeine retain more than 85 of fresh leaves, chlorophyll retains about 50, and vitamin loss is also less, thus forming green tea"The clear soup is green and leafy, and the taste is astringent"features: The latest scientific research results show that the natural substances retained in green tea have special effects on anti-aging, anti-cancer, anti-cancer, anti-bacterial, anti-inflammatory, etc.

Green tea: is unfermented tea (the degree of fermentation is zero), West Lake Longjing, Biluochun, Huangshan Maofeng, Lushan Yunwu, Xinyang Maojian are all green tea. Due to the different methods of processing and drying, green tea can be divided into roasted green tea, roasted green tea, steamed green tea and sun-dried green tea.

Difference Between Green Tea and Black Tea Green tea --- non-fermented tea (with zero degree of fermentation) Longjing tea, Biluochun. This is the most produced type of tea in China, and its variety ranks first in the world. Green tea has the characteristics of high aroma, mellow taste, beautiful shape, and brewing resistance.

The production process is all through the process of finishing, kneading and drying. Due to the different drying methods during processing, green tea can be divided into roasted green tea, roasted green tea, steamed green tea and sun-dried green tea. China's 18 tea-producing provinces (regions) all produce green tea.

China's green tea varieties rank first in the world, with tens of thousands of tons exported every year, accounting for about 70% of the world's tea market. China's traditional green tea, Mei tea and pearl tea, are popular with consumers at home and abroad for their high fragrance, mellow taste, beautiful shape and brewing resistance. Black tea--- fully fermented tea (80-90% fermentation) such as Keemun black tea, lychee black tea.

The difference between black tea and green tea lies in the different processing methods. Black tea is processed without killing, and withering, so that the fresh leaves lose a part of the water, and then kneaded (kneaded into strips or cut into granules), and then fermented, so that the tea polyphenols contained in it oxidize and turn into red compounds. This compound is partly soluble in water and partly insoluble in water, and accumulates in the leaves, thus forming red soup and red leaves.

There are three main categories of black tea: small black tea, gongfu black tea and black broken tea.

Black tea is a warm tea and is suitable for drinking all year round Green tea is a cold tea and can be drunk a little less in summer'

The color is different, black tea is red, green tea is green haha. There is a big difference between them, and there are great differences in the process of making tea, whether it is fermented or not, the color of the soup, the taste, the efficacy, etc.

Green tea tastes its fresh, authentic scent of nature. What black tea tastes is its connotation, the essence of thousands of tempers. One is like a newborn baby, the other is like an old man who has gone through the storm. I prefer green tea.

There are different ways to distinguish between different criteria. The most common and most commonly used is to divide into six types of tea according to the degree of fermentation and preparation method: black tea, green tea, yellow tea, white tea, green tea, dark tea and black tea

Fully fermented tea with a fermentation degree of 80 to 90%. The production process does not go through killing, but directly withering, kneading and cutting, and then carrying out complete fermentation, so that the tea polyphenols contained in the tea are oxidized into thearubigin, thus forming the dark red tea leaves and red tea soup unique to black tea. Green Tea:

It is a tea that is made without any fermentation process, and is directly killed, rolled, and dried after picking. The taste is fresh and mellow, refreshing and pleasant. Due to different construction methods, it can be divided into fried cyanotic green tea made by stir-frying in a pot, such as Longjing and Biluochun, and steamed cyanotic green tea steamed at high temperature, such as Japanese sencha and gyokuro, the former has a strong aroma and the latter has a fresh and new green feeling.

Hello: Black tea and green tea have different colors, different production processes, different shelf life, and different nutritional values.

Difference Between Black Tea and Green Tea.

Green Tea Unfermented tea.

Green tea's unique refreshing aroma and health benefits have been widely loved by the people of China, Japan and North Africa since ancient times. Green tea is prepared by drying and dehydrating the tea leaves in a large iron plate immediately after picking, so that the dark olive green color can be preserved, avoid further fermentation, and deepen into a tan color.

Black Tea Fully fermented tea.

The biggest difference between black tea and green tea is not the type of tea used, but whether the tea leaves have undergone a fermentation process.

As for why you let the tea ferment? There are many legends. Legend has it at 17

Century later, a ship belonging to the British East India Company came from China.

Wuyi) brought green tea to England due to a long voyage that accidentally fermented due to oxidation, but Western merchants were treated to this black, which has a heavier sweet, bitter taste, darker color, and aromatic smell

tea) is deeply attracted! Since then, China has begun to mass-produce this kind of new-style tea, which is good for foreigners. Today, fermented black tea accounts for about 90% of the world's tea production
