Recently, there has been frequent rainfall in South China, posing a challenge for storing Pu'er tea. Proper handling can lead to better transformation of the tea, while improper handling can cause issues such as mold. Storage has become a challenge, as different regions have varying climates, so is there a difference in storage methods? Don't worry, after reading this article, you will find answers to these questions. The Four Factors Affecting Pu'er Tea Storage When the same Pu'er tea is stored in different environments, the final aged quality will vary. The four factors that significantly influence the quality of Pu'er tea storage are "temperature," "humidity," "light protection," and "air." These play the most significant role in the transformation process of Pu'er tea during storage. 1. Temperature: Temperature plays a crucial role in the transformation of Pu'er tea. Excessively high temperatures can cause the tea to develop off-flavors; in excessively low temperatures, the transformation process slows down or even stops. Therefore, a relatively suitable temperature is essential for storing Pu'er tea. The temperature for storing Pu'er tea should not be too high or too low, and it is recommended to maintain it around 25°C ± 3°C. 2. Humidity: Humidity is also…

Storing Pu'er tea requires attention to sealing, avoiding light, preventing dampness and off-flavors, while also considering humidity and temperature. When storing, you can use a cardboard box; find a clean cardboard box, put the Pu'er tea inside, and store it in a tea room away from walls and the floor. For individual Pu'er tea cakes, you can use kraft paper bags or aluminum foil bags for storage, seal them well, and then place them in a ventilated area free of moisture. How to Store Pu'er Tea Cakes 1. Pu'er tea cakes are compressed from Pu'er tea leaves. Initially, they were made for convenience in transportation, so the shape and production method of Pu'er tea cakes determine their ability to be stored for a long time. For storing Pu'er tea cakes, you can choose clay jars, as they have good breathability and naturally provide ventilation. Clay jars do not need to be sealed; simply cover them with a layer of kraft paper to prevent dust. 2. When you first bring new Pu'er tea cakes home, avoid sealing them immediately for storage. Instead, let them air out in a dry place to get rid of any warehouse flavor. New Pu'er tea cakes…

Pu'er tea has storage value mainly because it becomes more fragrant over time through natural transformation. For teas from the same mountain, the older the vintage, the higher the price. This has led to one of the chaotic phenomena in the tea market—age fraud. However, in reality, for a Pu'er tea that has been stored for many years, it is very difficult to determine the specific storage time by blind tasting; only an estimate can be made. This is because the moisture content of the dry tea at the time of production, the storage environment (dryness/humidity, temperature, light), etc., can cause varying degrees of transformation differences in the same cake of tea, with the differences becoming more pronounced over time. This is the change that time brings to the tea, and also the pleasure of storing tea. So, how do we determine the age of a tea cake? Criteria for Determining the Age of Pu'er Tea First, color: The clearer and more transparent the tea liquor, the older the vintage. Clear transparency refers not to the depth of the tea liquor but rather to a slightly oily luster. Second, taste: Considering the overall balance of taste, excluding storage issues, the…

Enthusiasts of Pu'er tea who have been enjoying it for some time will undoubtedly have a fine collection at home, ready to be savored over time. It's crucial to properly manage humidity and odors to preserve your beloved teas. Here, we discuss the four don'ts and do's of storing Pu'er tea. The Four Taboos of Storing Pu'er Tea at Home Taboo One: Avoid High Temperatures High temperatures accelerate the degradation of chlorophyll in Pu'er tea, causing it to convert into de-magnified chlorophyll, changing its fresh green color to dark brown. The auto-oxidation of polyphenols and other substances also accelerates under high temperatures. Research shows that for every 10°C increase in temperature, the rate of browning in Pu'er tea accelerates, affecting its quality and aging process. Taboo Two: Avoid Direct Sunlight The plant pigments and lipids in Pu'er tea are susceptible to photochemical reactions, which can produce sun-dried and other off-flavors. Pu'er tea is particularly sensitive to light, so it should be stored away from direct sunlight. Taboo Three: Avoid Strong Odors Tea leaves are porous and easily absorb odors. Therefore, avoid storing Pu'er tea in places with strong odors, as these can taint the tea's natural flavor. Taboo Four: Avoid…

Pu'er tea, as one of the gems in Chinese teas, boasts a rich and unique set of qualities that exude an enchanting allure. From its appearance, high-quality Pu'er tea has robust and tightly bound leaves with a dark lustrous or brownish-red color, giving it a sense of stability and solidity. Round and well-formed cake teas, intricately crafted tuocha, and solid brick teas each exhibit their own unique beauty in craftsmanship. In terms of aroma, Pu'er tea stands out with its distinct character. It may contain a variety of rich and complex aromas, such as aged fragrance, camphor scent, woody aroma, jujube fragrance, ginseng-like scent, and more. The aroma of young teas is fresh and natural, becoming deeper, more restrained, and longer-lasting over time as the tea ages. The aged fragrance, a hallmark aroma of Pu'er tea after years of aging, seems to tell the story of time itself. In terms of taste, Pu'er tea is full-bodied with a thick and viscous liquor. Initially, there might be a slight bitterness, but this quickly transforms into a sweet aftertaste, creating a delightful experience of bitterness turning into sweetness that lingers on the palate. Its liquor has a rich texture that can be…

The simple character for tea contains profound truths about the cycle of nature. The character for tea, when broken down, means "human among grass and wood," implying that human nature is hidden within plants and that humans transform through their interaction with them. Adapting to the natural flow of time is the foundation of health preservation. Today, Cup Xiaocha selects 14 solar terms from the 24 solar terms and introduces 14 corresponding teas along with their benefits. There are specific considerations for drinking tea during different seasons. Adjust your tea-drinking habits according to natural changes. Tees picked at different times of the year have distinct characteristics, which can either nourish or drain, stimulate or calm, depending on the state of the person and the season. These seasonal teas adjust the body's imbalances to achieve harmony between yin and yang. As winter turns into spring and summer gives way to autumn, each tea has its own unique properties. 14 Seasonal Teas, Corresponding to 14 Benefits 1.

The plum rain is a concentrated period of rainfall that occurs annually from June to July in the mid-lower reaches of the Yangtze River, including tea areas in southern China, as well as subsequent mountain floods often accompanied by typhoons in August and September. Experience has shown that improper disaster prevention or neglect during the plum rain and mountain flood season can pose significant threats and losses to tea production, particularly in mountainous tea areas in southern China. To minimize the adverse effects of plum rain and subsequent mountain floods on tea production, especially in southern China, we have compiled measures for disaster prevention and mitigation in tea production for your reference. 1. Pay Attention to Plum Rain and Mountain Flood Forecast and Warning Information After June each year, tea areas, particularly those in mountainous regions of southern China, should promptly monitor the latest weather forecasts and mountain flood warnings. Be vigilant against the risk of mountain floods due to continuous rainfall or short-term heavy downpours and strong convection weather. Closely watch changes in weather conditions and rainfall levels. Once there is a forecast or warning of significant rainfall, it's better to be overly cautious and enter a state of…

Puer Tea Sealed Storage Experiment Sealed storage of Puer tea inevitably involves the issue of oxygen supply in the warehouse. According to post-fermentation theory, Puer tea requires oxygen and a certain level of humidity for post-fermentation, so the tea storage warehouse needs to be ventilated to allow the tea to undergo post-fermentation. However, many people have found that when tea is stored under ventilated conditions, while the infusion color turns red, it loses its aroma after two or three years, and the bitterness and astringency do not diminish over time. Additionally, under ventilated conditions, the tea's aroma naturally cannot be preserved. In fact, the later changes in Puer tea are influenced by two factors: one is microbial fermentation, which is an external effect; the other is the action of active enzymes within the tea leaves, which is an internal effect. After sealing and controlling the humidity, Puer tea does not require microbial fermentation, but instead relies primarily on the active enzymes present in the tea to facilitate its transformation. When storing tea in a sealed and oxygen-deprived environment, how would Puer tea change? This question led me to conduct an experiment on the effects of oxygen in sealed storage. Experimental…

Basic Introduction to Lushan He HongchaHe Hongcha is a traditional Chinese famous tea, created by Chinese tea farmers during the Ming Dynasty. As a black tea produced in He town, Lushan County, Jiangxi Province, it has been favored by people around the world since its inception. Merchants from all over China came to place orders, and merchants from Russia, Britain, India, and other countries also traveled long distances to He town for trade. He Hongcha became the most famous black tea in China and the "first Chinese tea to be exported," revered as the "Queen of Teas" by Westerners.He Hongcha was the first Chinese tea to be exported to the West. The high-quality He Hongcha 'Zhengshan Xiaozhong' is a traditional drink of the British royal family. The origin of 'Zhengshan Xiaozhong' is in Lushan. During the Ming and Qing Dynasties, masters of He Hongcha production from Lushan were spread throughout the country's black tea production areas. It is imperative to collect and organize this knowledge promptly so that the techniques of making He Hongcha can be passed down, and its charm can last!He Hongcha was once a calling card for China on the world stage. However, in the past four…

Dark tea undergoes external microbial fermentation, which involves not only the enzymatic reactions of the leaves themselves but also the assistance of external microorganisms. Professor Liu Zhonghua notes that in English descriptions, the process for black tea (red tea in Chinese) is referred to as “oxidation,” while dark tea truly undergoes “fermentation.” The wet-piling fermentation is a unique process in the making of dark tea. The wet-piling process itself is the fermentation process, where compressed dark tea leaves are sprinkled with water under controlled humidity and temperature conditions. This promotes the action of enzymes within the tea leaves and the activity of microorganisms, facilitating the transformation of the tea. The wet-piling process itself is the fermentation process. Compressed dark tea leaves are sprinkled with water under controlled humidity and temperature conditions. This promotes the action of enzymes within the tea leaves and the activity of microorganisms, facilitating the transformation of the tea. When the core temperature reaches 70 degrees Celsius, the pile is turned to ensure even temperature distribution, a process repeated multiple times. When all conditions are optimal, the metabolism of the microorganisms, along with the extracellular enzymes they secrete, can break down many substances in the tea, such…

Pu'er tea is known for becoming more fragrant with age, and enthusiasts often store and collect Pu'er teas they enjoy. However, improper storage can easily lead to moldy or flavor-deteriorated cakes. Here are four key storage tips recommended by ChaYouWang: 1. Circulating Air. Tea leaves are rich in microorganisms, and circulating air contains ample oxygen, which aids their proliferation and accelerates the transformation of the tea. However, hanging Pu'er tea in a place like a balcony can disperse its aroma, making it taste bland when brewed. Therefore, there should be moderate air circulation, but not too much exposure to wind. Additionally, ensure that the surrounding environment does not have any odors, as these can affect the natural scent of the tea. 2. Stable Temperature. The temperature at which Pu'er tea is stored should generally match room temperature, with 20-30 degrees Celsius being ideal. Temperatures that are too high can accelerate fermentation and cause the tea to become sour. Furthermore, during spring, summer, and autumn, changes in the tea will occur faster than in winter. Store the tea away from direct sunlight in a cool place. 3. Appropriate Humidity. The storage conditions for Pu'er tea should include some moisture, as a…

Tea grey blight is one of the most serious diseases affecting tea leaves, also known as tea shoot blight, primarily caused by the plant pathogenic fungus Pestalotiopsis sp.. This disease mainly affects mature and old leaves but can also infect young shoots, causing leaf withering, shedding, and even death of the entire plant, significantly impacting tea yield and quality. In recent years, there have been reports in China identifying a diversity of pathogens causing this disease, with multiple species within the genus Pestalotiopsis showing significant biological differences, making control challenging. Currently, chemical fungicides such as carbendazim, thiophanate-methyl, copper compounds, and others are primarily used for control, while biofungicides like pseudomonads, bacilli, and antibiotics (such as Wuyi mycin, camellia saponin, kasugamycin, and nisin) and extracts from approximately 30 plants, including Datura, are increasingly being applied. This article discusses the distribution and damage of tea grey blight, the biological characteristics of its causative agents, and epidemiological patterns, and proposes integrated control measures to provide guidance for practical disease management. I. Distribution and Damage Tea grey blight is widely distributed in tea-growing regions, including India and Japan, and occurs in all tea-producing areas in China. On young shoots, mature, and old leaves, the…

Monastery on Nine-day Mountain The chrysanthemums by the eastern fence are also turning yellow. Worldly people often indulge in wine. Who understands and enhances the fragrance of tea? The fifth typhoon of the year, Doksuri, has made landfall in Fujian, prompting a red alert from the National Meteorological Center. Meanwhile, Typhoon Khanun, the sixth of the season, is poised and gradually intensifying. The typhoons bring heavy rainfall and a great deal of moisture, making it a critical time for tea enthusiasts. Slight carelessness can result in moldy tea leaves... So, what should you pay attention to when storing tea during typhoon weather? Typhoon Tea Storage Tips Watch Out for High Temperatures In the scorching summer, while typhoons may arrive, many might mistakenly think that temperatures have dropped. However, even if there's an occasional decrease, high temperatures remain the norm, so tea lovers need to be extra cautious. Various substances in tea decompose under high temperatures, reducing the aroma, taste, and quality of the tea. Storing tea at temperatures below 10°C effectively inhibits browning. White tea, in particular, is best stored at temperatures between 25°C and 30°C. In a cool and dry environment, the enzymes within the tea can maintain sufficient…

Due to the frequent temperature changes in spring, various physiological functions of the human body tend to decline, and resistance weakens, making it easier for the body to be attacked by viruses. Here are some teas that can help maintain health. Black Tea 1. Keep Warm and Protect the Stomach The winter climate is in a low humidity state, and the human body is inevitably invaded by dampness and cold, causing discomfort in the stomach. Black tea has a sweet and gentle nature, nourishing the body's yang energy, enhancing its ability to resist the cold, and having the benefits of warming and protecting the stomach. 2. Prevent Cardiovascular Diseases and Protect Elderly Health Winter is a high-risk period for heart disease and stroke, with cardiovascular activity weakened due to factors such as temperature, which can trigger cardiovascular diseases. American medical research has found that heart disease patients who drink four cups of black tea daily see their blood vessel dilation increase from 6% to 10%. After brewing, 70% of potassium in black tea dissolves in the tea water, which helps enhance cardiac circulation. In the cold winter, the elderly can drink more black tea to combat the cold and prevent…

Those who enjoy drinking Pu'er ripe tea usually keep some at home. However, those lacking storage experience often find their tea has molded, deteriorated, or developed strange odors after a few years. So, how should we correctly store Pu'er tea? Key Points for Storing Pu'er Ripe Tea 1. Avoid Pollution: The environment in which you store Pu'er tea must be free from pollution. Pollution is something to be avoided when storing any type of tea, and this is no different for Pu'er tea. Pu'er tea can quickly absorb the odors of other substances, potentially masking or altering its own scent. Therefore, when storing Pu'er tea at home, it is crucial to prevent common odors like cooking oil, cosmetics, and medications from contaminating the tea. 2. Avoid High Temperatures: The ideal temperature range for storing Pu'er tea is between 20°C and 30°C. Higher temperatures can cause the tea to become acidic. In daily life, many regions do not meet this condition, so storing it at home under normal conditions is sufficient. It is important to note that during the storage process, avoid placing Pu'er tea near heat sources such as fireplaces, kitchens, or machinery where temperatures may rise. 3. Avoid Moisture:…

In daily life, to know how to preserve tea, one must first understand what damages it. Only then can one know how to store it to avoid such damage. Different types of tea have different characteristics and are damaged in different ways and to varying degrees, so the methods and requirements for their storage also differ. Many people do not know how to store green tea after opening it, which can lead to the tea going bad or losing its flavor. Under normal circumstances, green tea can be stored at room temperature for about a year; however, once opened, it should be transferred into an airtight container and used within two months if possible. Since green tea is prone to absorbing moisture, even unopened tea stored for too long will lose its aroma, so it should be brewed while fresh. Here are some key taboos to remember when storing green tea: The Five Taboos of Storing Green Tea 1. Avoid Moisture Firstly, one must be very careful to avoid moisture when storing green tea, as most tea enthusiasts know. Most teas have a strong tendency to absorb moisture and humidity. A relative humidity of 60% is suitable for storage, but…

       How to store tea? Many people are troubled by this question. Loving tea, they purchase countless quantities of it, originally intending to savor it slowly, only to often find the tea has gone bad due to improper storage, leading to significant waste. So, how exactly should tea be stored?        Four methods for storing tea        1. Refrigerator Storage        Storing tea in the refrigerator is common and simple, but it has its pros and cons. Let’s take a look:        Teas that are typically stored in the refrigerator include green tea, black tea, and processed white teas (like Anji White Tea and Tianmu Lake White Tea, not Fuding White Tea). Why can these types of tea be stored in the fridge?        This is because we tend to consume green and black teas quickly, and they are usually packaged in small quantities—ranging from 200 grams to as little as 50 grams. Since the storage volume is small and can be consumed within a month, storing them in the refrigerator for preservation is not an issue.        However, white tea and Pu'er tea are not…

Tea, by nature, is cold and can help clear the mind and soothe the spirit. Different people have different constitutions, which means they should drink different types of tea. Therefore, choosing the right tea and drinking it well starts with understanding the nature of the tea and the suitable groups of people for each type. Nature of Teas 01 Green Tea: The core process is "fixation," making its nature cold. People with a hot constitution, high stomach fire, or abundant energy can benefit from drinking green tea, as it has great effects in clearing heat, refreshing the mind, and boosting alertness. Green tea also has excellent radiation protection benefits, making it ideal for those who work on computers. White Tea: The core process involves "withering and sun drying" followed by natural storage, which transforms the tea's nature from cold to cool and then to mild. Fresh white teas share many properties with green tea, but the most significant difference is that while aged green tea becomes like grass, aged white tea becomes even more precious. As it ages, old white tea becomes even milder, making it suitable for a wider range of people. Oolong Tea (Blue Tea): The core process…

The aroma and taste of Pu'er tea after brewing are determined by the raw materials, processing techniques, and storage conditions. Due to different storage environments in various places, the same tea can develop completely different flavor profiles after a few years of aging. When selecting mid-aged and older teas, in addition to considering factors such as brand, price, and vintage, where the tea has been stored and aged is also very important. Many tea enthusiasts enjoy drinking Pu'er tea from the Kunming warehouse. What are the distinctive features of these teas? Kunming is located on the Yunnan plateau at a high altitude, with relatively small annual temperature fluctuations and a climate that is moderately warm and humid. These conditions make it very suitable for storing Pu'er tea. Compared to lower-altitude warehouses with higher temperatures and humidity, Pu'er tea stored in Kunming may undergo slower overall transformation, but it enjoys high recognition among tea enthusiasts and often commands better prices for the same vintage. Characteristics of Pu'er Tea Stored in the Kunming Warehouse First, Aroma: The aroma changes are relatively noticeable, often featuring honey-like notes, but undesirable aromas such as smoky, burnt, or moldy scents are more difficult to dissipate. Second,…

For the same tea, being stored in different places means facing different storage environments, which leads to differences in Puer tea collection between the north and south. When discussing with experienced tea enthusiasts, Kunlun found that sending the same tea to over 20 cities across the north and south resulted in variations in taste due to differences in storage conditions, humidity, temperature, and other factors. The difference in regional environments determines the methods for preserving Puer tea. So what are the characteristics of Puer tea storage in different regions? Storage can be divided into pure dry storage and natural storage. Natural storage involves keeping the tea in a natural environment on floors below the second level, without artificial processing. The tea undergoes natural transformation. The surface of the tea has a dull luster, and there is no dry aroma. The taste is not significantly different from pure dry storage. Pure dry storage involves keeping the tea in a professional tea warehouse above the second floor, where it naturally ferments under constant temperature and humidity. The surface of the tea has an oily sheen, and the tea has a fragrant aroma. The taste is rich and smooth, with a noticeable aftertaste.…

The best way to store white tea for short-term: Prepare a kraft paper bag, then put the white tea in the kraft paper bag, squeeze out the air in the bag, seal it well, and store it in a dry and odorless place. For long-term storage of white tea, use an aluminum foil bag to pack the white tea and seal it, then put another layer of plastic bag on the outside, squeeze out the air in the bag, finally place it in a cardboard box, and store it in a cool place. The Method of Storing White Tea Since loose white tea is too light and takes up a lot of space, pressing it into cakes is more convenient; secondly, pressing it into cakes can greatly reduce the loss of tea (crumbs) from long-term storage and occasional handling. Thirdly, compared with Pu'er tea, small to medium-leafed white tea is less resistant to oxidation (small to medium leaves have naturally less effective internal substances than large leaves and cannot withstand much handling), pressing it into white tea cakes reduces the amount of oxygen that comes into contact with the white tea in the space, allowing the white tea to be…
