Tea Knowledge

There are six main types of tea, and the storage time after opening varies depending on the type. Green and yellow teas can typically be stored for about 2 to 3 months after opening. These types of tea are particularly susceptible to oxidation and should be consumed as soon as possible. Black and Oolong teas can be stored for 6 to 12 months after opening. Dark teas and Pu'er teas can be stored long-term if properly preserved after opening. How Long Can Opened Tea Be Stored? If tea is left unsealed after opening, it can be stored for around 3 months. The key to preserving tea is keeping it dry, sealed, away from light, and free from odors. Leaving opened tea unsealed makes it susceptible to external influences, accelerating the oxidation of its internal components and shortening its shelf life (to around 3 months). If you seal the tea in an aluminum bag and place it in a metal tin, then cover the tin with a plastic bag and tie it securely, you can store it in the refrigerator. How to Store Opened Tea: After opening, store the tea in containers or bags with high airtightness at room temperature. To…

It's spring tea season once again. Whenever the tea season comes around, we often hear about "spring tea." What exactly is spring tea? Why is it so highly regarded in the tea industry? Spring tea is made from the buds and leaves of tea trees that have emerged after their winter dormancy. The tea buds accumulate abundant organic substances during their winter dormancy. In addition, the moderate temperatures and sufficient rainfall of spring result in plump, nutrient-rich tea buds. The freshness, fullness, and balance of spring tea are extremely high. In particular, the first flush of spring tea embodies the essence of the entire spring season. Characteristics of Pu'er Spring Tea After a winter's hibernation, tea trees store more energy and nutrients due to their slow growth. Moreover, the growth of tea trees in winter primarily occurs at the roots, where amino acids are produced and then transported to the tips of the tree—the tea buds. Amino acids are crucial for the synthesis of aromatic compounds. In terms of appearance, spring tea has fresh leaves with a lustrous color, thick and small leaves with fine veins, and not very noticeable serrated edges. There are many fine hairs on the leaves.…

Tea stored for a period, whether vacuum-packed or not, will undergo some changes. The chlorophyll and polyphenol compounds in the tea can cause the tea to age, turning yellow, red, and developing an off-flavor, and there is even the possibility of mold growth. Therefore, when drinking tea that has been stored for a while, first confirm whether the tea has molded. If there is a musty smell, it should not be consumed. If there is only a slight aged or stale flavor, you can use a brewing method to address it. Method one: The water temperature should be high, preferably boiling. The first infusion should be longer than usual, then discard the infusion without drinking it. Starting with the second infusion, steep for half the normal time, using a quick brew method, and drink it as soon as possible while it's hot. Method two: Reduce the water temperature by a few degrees and follow the normal brewing time. This can avoid the bitterness of the tea liquor. Method three: It is best to switch to brewing in a large teapot, such as a teapot warmer, and reduce the proportion of tea leaves. The taste will be better. For tea stored…

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 differs from other types of tea. The quality of a particular tea not only affects its taste but also impacts its storage and potential for appreciation in value. When selecting Pu'er tea, careful examination is necessary. Here’s how to identify the grade of Pu'er tea. How to Distinguish the Quality of Pu'er Tea! First, look at the appearance. Check if the leaves are whole and uniform. Generally, young leaves are finer while older ones are larger. The exterior should be round and lustrous, with the overall structure intact. If the leaves do not appear clearly defined and instead seem fragmented and uneven, it's likely an issue with processing. Second, observe the color. Good tea should have a luster and not appear dull. High-quality loose Pu'er tea has a fragrant aroma and a glossy appearance. Inferior tea has incomplete leaves and a dark, lifeless color without any sheen. Third, inspect the liquor color. Good Pu'er tea produces a clear, bright infusion with an oil-like film on the surface. Lower quality tea will appear dark, murky, and unclean. Fourth, smell the aroma. The fragrance should be pure and free of off-flavors or impurities. High-quality raw Pu'er has a fresh, uplifting…

The differences between raw and ripe Pu'er tea: 1. Raw tea is mainly green or dark green in color; ripe tea is black or reddish-brown. 2. After picking, raw tea goes through processes such as withering, fixation, etc.; ripe tea also goes through fixation, kneading, etc. after picking. 3. After brewing, the infusion of raw tea is light green or golden yellow; the infusion of ripe tea is chestnut red or dark red. 4. The water temperature for brewing raw tea is slightly lower; ripe tea can be brewed with boiling water. The differences between raw and ripe Pu'er tea: 1. Process differences Raw Pu'er tea is made from fresh leaves that undergo withering, fixation, kneading, sun-drying, steaming, and pressing. Ripe Pu'er tea is made from fresh leaves that undergo withering, fixation, kneading, sun-drying, and pile fermentation. In other words, ripe Pu'er tea is made through pile fermentation based on sun-dried green tea. However, there are no loose teas for raw Pu'er; only compressed teas exist. Teas before steaming and pressing are just sun-dried green teas, which belong to a type of green tea. Only ripe Pu'er tea has both loose and compressed forms. Tea cakes, brick teas, and tuo…

Purple clay pots are jewels among tea wares, cherished for their unique breathability and ability to absorb tea aromas. However, not all teas are ideal for brewing in these pots. So, which teas are best suited for purple clay pots? Let’s find out together. (Image source: network, delete upon request) Varieties and Characteristics of Purple Clay Pots Purple clay pots come in many varieties, each with its own unique characteristics suitable for different types of tea. Commonly found purple clay pots include Zini (purple clay), Hongni (red clay), and Duan Ni (segmented clay).

"Tea" has become the most popular "beverage" of our time. Beyond simply quenching thirst, tea can help with digestion, reduce greasiness, lower internal heat, improve eyesight, calm the mind, relieve stress, stimulate saliva production, and quench thirst. For those who are absolutely devoted to tea, not a single bit of tea leaf goes to waste, and perhaps savoring tea is also a spiritual pursuit. However, it's common for too much tea to be used or for it not to be fully savored, inadvertently resulting in "leftover tea." Do you understand "leftover tea"? Can you drink leftover tea, and what happens if you do? A series of questions might leave you feeling a bit confused. No worries, today we'll provide some insights into the "history" of leftover tea. Can You Drink Leftover Tea? Leftover tea is often considered undrinkable because it has been sitting for too long, causing vitamins to degrade. The proteins and sugars in tea leaves can become nutrients for harmful microorganisms, which is why people generally believe that leftover tea should not be consumed. Tea typically remains in the body for about three hours, and even longer for strong tea, leading to an accumulation of caffeine that can…

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…

When buying tea, the variety can be overwhelming, often making it difficult for people to know where to start. Selecting tea has become a real challenge for tea enthusiasts. To buy suitable tea, in addition to following the steps of "Observation, Smelling, Inquiry, and Brewing," it's also important to avoid common pitfalls when purchasing tea. ObservationObservation means looking at the shape of the tea: whether it is uniform, and how shiny its color is. Evaluate the quality of various teas based on their uniformity, luster, and the amount of broken leaves and twigs they contain. For example, green tea should have a fresh green color with visible white downy hairs (better if it does), while yellow or even reddish, dull colors indicate lower quality. A clear tea infusion is better. Some famous teas have unique shapes: West Lake Longjing is usually smooth, flat, and straight with a rice-like yellow hue and no visible downy hairs; Huangshan Maofeng has many downy hairs and a peak-like appearance; Xinyang Maojian is fine, straight, and round with many downy hairs; Biluochun has slender, tightly curled leaves resembling snails. If the tea doesn't look good visually, trust your instincts and don't be swayed by the…

When storing Pu'er tea, it's important to ensure it is sealed, protected from light, free of odd odors, well-ventilated, and kept at a moderate temperature and humidity. Generally speaking, there are three methods for storing Pu'er tea. The first method involves placing the tea in a Kraft paper bag, squeezing out excess air, sealing the bag, and keeping it in a study or tea room. The second method is suitable for frequently accessed or opened Pu'er tea, which can be wrapped in cotton paper and stored in a jar. The third method is for whole bundles of Pu'er tea, which should be stored in their original packaging and sealed in a cardboard box. Three Methods for Storing Pu'er Tea Method One: Kraft Paper Bag For individual cakes or small quantities of Pu'er tea, Kraft paper bags can be used. 1.

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…

Tea lovers often keep a good stock of tea at home. Some store their tea in the fridge, or even buy a small fridge specifically for this purpose. However, this is a common misconception – whether tea should be stored in the fridge depends on the type. Here are some basics about storing tea in the fridge. Green tea, yellow tea, and some oolong teas need to be refrigerated, while Pu'er, white tea, dark tea, black tea, and oolong teas with higher fermentation levels should be stored at room temperature and sealed. When storing these teas, it's important to prevent odors, dampness, ensure airtight conditions, and avoid light. If you plan to consume the tea within two months, simply store it in a cool place at room temperature. Green tea, yellow tea, and lightly fermented oolong teas need to be refrigerated. These teas have low fermentation levels or are unfermented, making them highly active and susceptible to environmental factors and oxidation, which can alter their quality. To maintain their flavor and aroma, they should be properly sealed and refrigerated. Which Teas Need Refrigeration? The main types of tea that benefit from fridge storage are green tea and lightly oxidized oolong…

Experiencing Pu'er tea requires calmness and a gradual process, involving many sensory perceptions to appreciate the evolving flavors. How can one appreciate Pu'er tea, particularly raw Pu'er? Here’s how to discern the quality of raw Pu'er tea when purchasing: Selecting Raw Pu'er Tea Look at the tea: shape, processing, color. Feel the tea: compactness, check inside and outside. Scent: dry tea, tea infusion. Observe the infusion: color, clarity, turbidity. Taste: fullness and smoothness, aftertaste and salivation. Looking at the Tea Shape: High-quality raw Pu'er tea has complete and uniform strands, with moderate buds, typically picked as one bud with two to three leaves. The leaves should be clean without impurities, yellow leaves, or too many stalks. Mature production process: The shape of the cake is uniformly balanced, neatly compacted with consistent thickness and edges. Color by age: Short-aged: dark green; Long-aged: brownish red. Feeling the Tea Compactness: A loose body means faster aging under equal storage conditions, while a compact body ages more slowly. Check inside and outside: Some teas have higher-grade leaves on the surface for better appearance, but a consistent blend means the entire compressed tea is of uniform quality, not just attractive on the outside. Scenting the…

With the arrival of spring, many tea regions have already started harvesting their spring teas, which will soon be available on the market. After a whole winter of rest and rejuvenation, tea plants have accumulated rich internal substances. During this period, the tea has a full flavor, is strong in taste, and is relatively more durable when steeped, making spring tea the best of the year in the minds of many tea enthusiasts. The first spring tea is the first batch of tea leaves picked in spring. As long as it is the first harvest of the year, it is called the first flush spring tea. This is also the first batch of tea to sprout each year. These leaves are smaller with larger, more abundant buds, good aroma, and a full-bodied, rich taste. What is the first flush spring tea? The spring tea, as the name suggests, is tea harvested and processed during the spring season, that is, tea picked and processed between the beginning of spring and the beginning of summer. Puer spring tea can be divided into “first flush,” “second flush,” and “end-of-spring” teas. “First flush” tea is made from the first tender shoots and leaves harvested…

When did the variety of Wuyi Rock Tea originate? According to "The New Gazetteer of Tong'an County," "Wuyi tea was originally wild, not planted by human hands. It is said that it was first discovered by an old man... The old man first offered the tea and after his death, he was revered as a mountain deity and enjoyed temple sacrifices." In Fan Zhongyan's "Song of Tea Competition with Zhang Min," it states: "The miraculous tea by the stream surpasses all in the world, cultivated since ancient times by the immortals of Wuyi." The "immortals of Wuyi" likely refer to the distant ancestors of the Wuyi tea region, traditionally believed to be Wuyi Jun or Pengzu. According to Hu Haochuan's research, Wuyi Caicha evolved from a wild species. Professor Zhuang Wanfang believes that Wuyi tea was cultivated by ancients or possibly introduced from Wulong Ridge in Zhejiang Province. Caicha is the mother of Wuyi teas and is the collective term for the sexually propagated group of tea trees in Wuyi. This means these teas are as common as the vegetables grown around the house, only for everyday drinking. In the natural environment of Wuyi Mountain, due to the cross-pollination of…

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…

For Pu'er tea, many friends find it complex, especially those who are just starting to explore the world of Pu'er tea. The diverse flavors from different regions and the concept that Pu'er tea improves with age can be confusing. Additionally, seeing a wide range of prices in the market makes it even harder to know where to start, often leaving buyers guessing. In this article, we will discuss how a high-quality Pu'er tea should look, smell, taste, and appear, providing useful information for tea enthusiasts when selecting their teas. Five Quality Standards for Premium Pu'er Tea 1. Dry Leaf Appearance: The compressed tea leaves should have an appropriate level of tightness and uniformity; they should have a smooth and lustrous color. For ripe Pu'er tea, the color should be dark brown with a glossy sheen and visible golden tips. For raw Pu'er tea, the color should be dark and lustrous. 2. Aroma: Assess the purity and longevity of the tea's fragrance A standard-quality Pu'er tea should have a pure aroma, free from any off-flavors, impurities, or unpleasant moldy odors. Pu'er tea is known for its ability to improve with age, and its fragrance develops through microbial and enzymatic activities during…

What is blended Dahongpao?Pure Dahongpao comes from the asexual propagation of cuttings from the mother tree, processed separately. Blended Dahongpao is a commercial product different from pure Dahongpao, created to meet market demand for Dahongpao by blending different varieties from Wuyi Mountain in certain proportions. It has distinct quality characteristics that differ from its blending ingredients. The Origin of Blended Dahongpao The blending of Dahongpao has ancient roots. The six mother trees growing above the Nine Dragon Gullies are not of a single variety but come from different lineages, with differing leaf shapes and budding periods, as well as different picking times. During the harvest period, they are picked in two to three batches, then refined and roasted together to produce the final product known as "Mother Tree Dahongpao." In 1985, technology personnel at the Wuyi Mountain Tea Research Institute blended "Dahongpao" using high-quality Wuyi rock teas like Rougui and Shuixian along with pure Dahongpao. The resulting tea had excellent aroma, liquor color, and taste, with a strong rock tea character, quickly gaining consumer approval. With advances in technology and increased innovation, various high-quality blends of Dahongpao have emerged according to market demand, and blended Dahongpao has become an important…

Montding Sweet Dew Tea is a renowned tea with a long history in China and one of the earliest curly green teas in the country. Moderate consumption during summer has beneficial health effects, making it popular among many tea enthusiasts. However, as a type of green tea, the shelf life of Montding Sweet Dew Tea is similar to other green teas and is not very long. Below are detailed explanations regarding the shelf life of Montding Sweet Dew Tea. How Long is the Shelf Life of Montding Sweet Dew Tea? Montding Sweet Dew Tea belongs to the category of green tea, which is unfermented, hence its shelf life is relatively short.

Of course, if you have stored Montding Sweet Dew Tea for an extended period and are unsure whether it has expired, you can judge by observing its taste and the color of the tea infusion. National standards have been set…

Many of my friends adore Liubao tea. Whenever we gather for a tea session, some tea enthusiasts always request recommendations for one or two daily staple teas. A "daily staple tea" refers to a tea with good quality and flavor that meets one's needs in terms of strength, at a reasonable price, making it suitable for daily consumption. Generally, this type of tea achieves a balance between quality and cost. Inferior teas are disregarded no matter how cheap they may be, but Liubao teas priced over ten thousand yuan per catty, such as the "Wutu Heihe" and 0101 Liubao teas, are clearly not affordable for most people and therefore cannot become the "daily staple tea" loved by ordinary folks. Considering both the desire for a tea that is "delicious" and one that doesn't make you feel guilty about drinking, selecting an appropriate Liubao tea can be quite challenging. The editor has drawn upon the extensive tasting experiences of many Liubao tea enthusiasts and found that the price range for entry-level daily staple teas is typically between 100-200 yuan per catty, while mid-range daily staple teas are priced between 200-500 yuan per catty. Teas priced above 500 yuan per catty are…

Tea lovers have likely heard about the practice of "washing tea." Some say the first infusion should be discarded, while others disagree. So, should you discard the first infusion? Let's explore this topic today. (Image source: Internet. Please delete if infringing.) What is "Washing Tea"? The term "washing tea" is familiar; literally, it means "washing the tea leaves." Many people are accustomed to soaking the tea leaves before brewing with a purple clay pot or a covered bowl, then discarding the first infusion, which they call "washing tea." In professional tea ceremony procedures, this is even listed as a mandatory step. But is "washing tea" really necessary? (Image source: Internet. Please delete if infringing.) The Historical Origins of "Washing Tea" "Washing tea" has a long history. In the Ming Dynasty, Tu Long's "Kao Pan Yu Shi" mentions: "When brewing tea, first wash the tea with hot water to remove dust, dirt, and coldness, which makes the tea more flavorful." This suggests that the ancient purpose of washing tea was to remove impurities and coldness from the surface of the leaves, thereby improving its taste. However, in modern tea processing, is this practice still necessary? Is "Washing Tea" Necessary for Modern…

As Pu'er tea becomes more widely known and accepted, appreciating Pu'er tea has turned into a healthy, fashionable, and refined form of leisure and entertainment. The appreciation of Pu'er tea is a comprehensive sensory experience, primarily involving the integrated use of vision, taste, and smell to identify, perceive, and experience Pu'er tea with one's heart. Pu'er tea comes in two forms: loose-leaf and compressed. Loose-leaf Pu'er is categorized into special grade and grades one through ten, as well as grade-outside teas. Compressed Pu'er can be found in shapes such as cakes, bricks, tuos, pillars, golden pumpkins, and heads. There are several methods for identifying Pu'er tea: visual inspection, brewing evaluation, leaf base examination, and tasting. Among these, tasting is the most important. The identification of Pu'er tea mainly relies on sensory judgment, starting with observing its appearance and smelling it, then brewing it. After brewing, examine the liquor color, which can range from gemstone red, carnelian red, to tiger red, with gemstone red being the rarest and considered the pinnacle of tea quality. Next, inspect the leaf base (spent leaves), focusing on its softness, color, and uniformity. Finally, savor its taste. Tasting primarily involves sampling the brewed Pu'er tea, smelling…
