Basic Introduction to Yantai Green TeaYantai Green Tea is a specialty of the Yantai region in Shandong Province, China, and is one of the most representative local products in Shandong Province.Yantai is one of the highest latitude tea-producing areas in China, influenced by a temperate humid marine climate. The slow growth of tea trees results in rich accumulation of nutrients in the leaves, which are of high quality and characterized by "thick leaves and abundant organic and inorganic compounds."Yantai Green Tea features thick green tea leaves with rich nutritional content, particularly high levels of amino acids and chlorophyll, far exceeding those of southern teas. Overall, it possesses the quality characteristics of high-altitude teas. However, due to the thickness of the leaves, processed Yantai Green Tea does not appear as delicate as southern teas.Tests conducted by the Ministry of Agriculture's Tea Quality Supervision and Inspection Center showed that the water-soluble extractives in green tea produced in Yantai were 48.6%, 14% higher than those in southern teas. Important indicators reflecting the quality of green tea, such as amino acids, polyphenols, caffeine, and chlorophyll, can match those of southern teas. It has the characteristics of "bright green liquor, thick leaves, strong aroma, and…

Gathering around a teapot, having heartfelt conversations, and listening to the sound of boiling water can be an extremely cozy experience. However, many people still have misconceptions about cooking tea. Let's take a look at some things to avoid so that your tea drinking doesn't turn into an embarrassing situation. 01 Cooking Tea Directly in an Iron Teapot Generally, iron teapots have pores and are "breathable." When cooking tea leaves, iron reacts with tannic acid in the tea, forming ferric tannate, which is also a component of blue-black ink. As a result, the tea broth turns bluish-black. While not toxic, it can irritate the stomach lining, causing nausea, vomiting, and digestive issues. Suggestion: Iron teapots are suitable for boiling water, but for cooking tea leaves, clay or glass teapots are recommended for better taste. 02 Any Type of Tea Can Be Cooked There are generally two types of tea suitable for cooking. The first is heavily fermented teas like ripe Pu'er, Liu Bao tea, old tea heads, old tea leaves, aged white tea, and aged Tieguanyin. The second type is aged teas, such as aged white tea, aged Pu'er, aged Wuyi rock tea, and aged Tieguanyin. On the other hand,…

Many people find that the raw Pu'er tea becomes increasingly astringent with each infusion, why is this so? Why does the astringency increase with the number of infusions? The reasons for the strong astringency in raw Pu'er tea are multifaceted, including the rate at which the tea's compounds are released, the influence of catechins, the reinforcing effect of astringency, excessive leaf-to-water ratio, too high water temperature when brewing young raw Pu'er, incorrect brewing time, improper pouring technique, and the quality of the water used for brewing. These factors cause the drinker to experience an increase in astringency with each infusion. This explains why raw Pu'er tea becomes more astringent as it is repeatedly steeped. However, if the astringency is due to the natural release of compounds from the tea leaves and the tea is of good quality, the transformation happens quickly, allowing the astringency to convert into a sweet aftertaste before it can become overly pronounced, leaving the mouth feeling pleasantly moist. If the problem lies in the brewing method, then using the correct approach is essential to bring out the true flavors of raw Pu'er tea. The Rate at Which Compounds Are Released During brewing, amino acids, caffeine, and…

White tea actually cools the body. It is a minimally processed type of tea. White tea's nature is inherently cool, and during its production, it is merely sun-dried or gently dried over low heat without undergoing any other processes like steaming or rolling. Therefore, its inherent properties remain intact, making it particularly effective for reducing fever and cooling the body. If you experience symptoms such as swollen gums or canker sores due to heatiness, drinking some white tea may help alleviate these issues. Does White Tea Cool the Body or Cause Heatiness? In the "Compendium of Materia Medica," Li Shizhen recorded that "white tea is cool in nature, similar to rhino horn." Traditional Chinese medicine has proven that white tea has a slightly warm, yet cool nature, and is effective for reducing fever, cooling the body, and eliminating dampness and toxins. For a long time, in white tea-producing areas like Fuding, a concoction of white tea and rock sugar has been used to cool the body, relieve dryness, treat toothaches, constipation, and discomfort from being out of one's element. Aged white tea is even used to treat illnesses like measles and fevers in children. Moreover, drinking white tea can alleviate…

The liquor of black tea is bright red, and its taste is mellow, sweet, and pleasant. However, many friends find that black tea can be quite particular when brewing it; if the temperature isn’t right, the tea doesn’t taste as it should. To understand this issue of water temperature, we must first consider another question: the rate at which the internal components of the tea leaves are released. It’s easy to understand that the higher the water temperature, the faster these components will be released. If you want a cup of tea that is full-bodied in color, aroma, and flavor quickly, then boiling water is the way to go. There has always been a belief in the industry that tender teas can be scalded by boiling water. However, considering green tea is often processed at temperatures above 85°C during stir-frying, where does the idea of scalding come from? Black tea is not stir-fried but goes through drying or sun-drying processes, typically at temperatures below 85°C. This leads to an interesting question: stir-fried green tea cannot be brewed with boiling water, nor can fermented black tea, suggesting that black tea is even more delicate than green tea? When it comes to…

Black tea is made from fully fermented (fermentation degree greater than 80%) tea leaves, using new buds and leaves suitable for making this type of tea as raw materials.

Green tea is rich in vitamins, and long-term consumption can promote liver cell metabolism, enhance liver cell vitality, and maintain the liver in a state of robust activity.…

When is the best time to drink tea? Generally, the best times to drink tea are after breakfast and between 3:00 PM to 5:00 PM. The specifics can vary depending on individual circumstances. When is the Best Time to Drink Tea? Drinking tea is a great habit and an excellent way to cultivate one’s mind and body. It is recommended to drink tea after meals if it does not affect your sleep. Tea and coffee are two of the world's most beneficial natural beverages. Tea mainly contains polyphenols and caffeine. Some people are very sensitive to polyphenols and may experience symptoms of “tea drunkenness” when drinking tea on an empty stomach, such as dizziness or disorientation. Therefore, it is not advisable to drink tea on an empty stomach. Some people may be sensitive to caffeine, and drinking tea after dinner can affect their sleep. Tea aids digestion and is a bitter, qi-lowering beverage. It is important to note that tea contains large amounts of tannic acid, which can bind with proteins to form tannin-proteins, causing astringency and reducing intestinal motility. This can prolong the retention time of food residue in the intestines, leading to constipation. Therefore, it is best not…

Fifth article: Differences in Small Heap Fermentation, Large Heap Fermentation, and Tea Evolution Ripe Tea Techniques? The following is Part Four, focusing on storing Puer, pursuing famous mountain origins or quality? Shi Yun: I would like to express great appreciation for Teacher Li Yang's sharing. A young lady just now wanted to ask President Zheng and Teacher Li Yang about a conversion issue. Zhou Xin: Teacher, regarding storage, for example, Tianmen Mountain, does it mean that as long as its glycoside content is high, and the catechin and caffeine content is low, it suggests that it requires higher humidity? And Menghai tea, with higher catechin and caffeine content, has lower humidity requirements, only forming white frost when humidity exceeds 14%. This is the first time I've heard this, so I want to confirm if my understanding is correct. Zheng Shaohong: Indeed. For instance,…

The question of whether dark tea is better steeped or boiled is one that often comes up. Opinions on this matter vary widely, with each side presenting their own arguments. This can be particularly confusing for those new to dark tea. In fact, both steeping and boiling are viable options for drinking dark tea, they're simply different ways of enjoying the beverage. However, there is a common misconception that dark tea should only be boiled, as this is how it is traditionally prepared by nomadic people on the frontier, be it in milk tea or butter tea. The suitability of steeping versus boiling dark tea really depends on the individual, the setting, the age of the tea, and the grade of the raw material used, and there's no one-size-fits-all answer. Historically, dark tea was primarily sold to provinces where ethnic minorities lived in the northwest border regions, hence the name "border tea." Nomads in these areas consume a diet rich in beef, mutton, and dairy products, which are high in fat and low in dietary fiber and vitamins. This makes dark tea a necessity for them. As such, dark tea has been an indispensable part of life for the people…

Ripened tea can nourish the stomach because, after fermentation, it produces a rich variety of beneficial bacterial colonies that protect the gastric mucosa. It serves to strengthen the spleen and stomach, protect the stomach, and lower blood lipids. Although ripened tea has certain benefits, it should be consumed in moderation to avoid overburdening the gastrointestinal tract and causing discomfort. Ripened tea is made by piling and fermenting under suitable temperature and humidity conditions. During production, bacteria grow and multiply. Under the action of these bacteria, large biomolecular nucleic acid components are transformed into new soluble monosaccharides and oligosaccharides. Additionally, during fermentation, vitamin C increases significantly, which can enhance the function of the immune system. Furthermore, the abundant beneficial bacterial colonies in fermented ripened tea do not irritate the stomach when ingested but instead form a protective film on its surface, providing beneficial protection. Why is drinking ripened tea advocated? The best way to use ripened Pu'er tea for nourishing the stomach: Upon waking up in the morning, drink a warm cup of ripened tea while on an empty stomach, preferably choosing high-quality ripened Pu'er tea that has been stored for more than three years. If possible, drink naturally fermented Pu'er…

 Fermented tea is a type of tea production process, referring to tea made after the tea leaves have undergone withering, cutting, fermentation, and drying in the initial manufacturing steps to produce crude tea, which is then refined. Depending on the degree of fermentation of the tea leaves, fermented teas can be categorized into lightly fermented tea, semi-fermented tea, fully fermented tea, and post-fermented tea. Lightly Fermented Lightly fermented refers to teas that do not undergo a fermentation process, such as green tea. This category of tea has a natural aroma and a refreshing taste. However, it is relatively cooling in nature, and while it can help reduce internal heat, it should not be consumed regularly over long periods. Semi-Fermented Semi-fermented refers to the process where the chlorophyll in the tea leaves is destroyed during production, and the fermentation degree ranges from 20% to 70%. Examples include Tieguanyin and Wuyi tea, which are considered semi-fermented teas. Semi-fermented teas contain higher levels of polyphenols, aldehydes, and alcohols, making them more likely to induce stomach problems for people with poor gastrointestinal function. Additionally, they contain caffeine, active alkaloids, and various aromatic substances that can stimulate the central nervous system. People with neurasthenia, heart…

Puer tea does indeed improve with age, primarily because the chemical components within the leaves undergo carbonization over time, significantly altering the taste. Once it has been aged for 15 to 20 years or more, the brewed tea becomes even more enjoyable. However, it is not recommended to store the tea indefinitely, as this can cause the loss of its nutritional components. Is Puer Tea Better with Age? The saying that Puer tea improves with age comes with conditions. Not all Puer teas benefit from extended storage. The longer aging process enhances the aroma and flavor, making the tea more complex and desirable. As a result, older Puer teas are often more expensive. However, there is an optimal period for aging, during which the unique qualities and aged aroma develop. This transformation is due to post-fermentation processes that occur in storage, where compounds like polyphenols, amino acids, and sugars change, leading to an ideal color and aroma. If stored improperly or for too long, the quality can deteriorate, and beneficial components may degrade or oxidize, losing the tea's characteristic flavors. Conditions for Puer Tea to Improve with Age 1. Good Raw Material Sunlight, soil, climate, and temperature fundamentally determine the…

I was out of town on a business trip. After finishing my work, a friend contacted me and invited me for tea. However, since it was a weekday, we decided to meet in his office. This tea session made me realize a profound issue: what would the infusion of top-quality Pu'er tea taste like when brewed with hard water that had been sitting for half a month? Good Tea, Lesser Water My friend has grown up around tea and has maintained a clean lifestyle for years within the system, almost abstaining from smoking and drinking, with his greatest hobby being tea. When we arrived at his office, he opened a cabinet against the wall, which was packed with metal tea boxes, wooden tea chests, and various kinds of tea, including Pu'er cakes, Tieguanyin, and green tea, some of them quite expensive. The tea was excellent, but the brewing utensils were excessively simple. He used a standard government-issued white porcelain mug with a handle for drinking and a low-quality portable brewing cup for brewing, while boiling water in a cheap thin-steel electric kettle. With a wry smile, my friend apologized, saying, "The environment here can't compare to your meticulously arranged tea…
