Pu'er tea is mainly produced in Xishuangbanna, Lincang, Pu'er and other areas in Yunnan Province. Pu'er tea pays attention to brewing techniques and drinking art. It has rich drinking methods, which can be either pure or mixed. How to preserve dried Pu'er tea cake? What are the preservation conditions of Pu'er tea? Let's have a look.
The preservation conditions of Pu'er tea are as follows
1. Keep Pu'er tea away from high temperature
High temperature will accelerate the degradation of chlorophyll in Pu'er tea, the chlorophyll will continue to transform to magnesium free chlorophyll, the bright green will turn dark brown, and the automatic oxidation of tea polyphenols and other substances will be accelerated under high temperature; according to research, every 10 ℃ increase in temperature, Pu'er tea browning speed will be accelerated, tea is easy to aging, affecting the quality.
2. Store Pu'er tea away from direct sunlight
The plant pigments and lipids in Pu'er tea are prone to photochemical reactions, resulting in sunlight and other flavors. Pu'er tea is particularly sensitive to light, so keep it away from direct sunlight.
3. Store Pu'er tea to avoid peculiar smell
Tea is a kind of porous and loose body, which can absorb peculiar smell easily. Avoid the existence of odor in the place where Pu'er tea is stored. The odor is easy to make Pu'er tea absorb the odor and affect its essential flavor. A key point of storing Pu'er tea is not to let the tea absorb the peculiar smell produced in the family. Every family always has such or that kind of household miscellaneous smell, such as cooking and eating, the smell of washing products used in bathing and cleaning, and the temperature and humidity of toxic gas released from furniture.
Tea sucks. When storing Pu'er tea at home, do not store it near the space with peculiar smell or mixed taste, such as toilet, kitchen, newly bought cabinet, etc.
4. Keep Pu'er tea away from moisture
Pu'er tea is a porous and loose body. Many substances are hydrophilic compounds, which are easy to absorb moisture and restore moisture. The moisture content of Pu'er tea increases after moisture recovery. When the moisture content of Pu'er tea exceeds 8%, Pu'er tea will deteriorate rapidly and mildew will occur after microorganism breeding. Keep in a cool and dry place.
5. Storage environment of Pu'er tea
It should be stored in a warm, humid, aerobic and odorless space. If you want to transform Pu'er tea into a better quality, it is not just a matter of buying it home. It is also necessary to regularly inspect Pu'er tea and try to adjust the environment to the best state. In addition to checking the transformation degree, the inspection content should also check whether it is moldy, or whether there are insects. If so, it should be handled in time, so as not to be remedied after becoming serious.
If conditions permit, the environment should be regularly scheduled to be in the most appropriate state, such as adjusting the temperature and temperature. If there is no condition, at least ventilation should be conducted to prevent the tea from moldy. However, in the south of China, the rainy season or the day of returning to the South (that is, the season from winter to spring), the weather is very humid. At this time, we should pay special attention to the fact that the air conditioner can be turned on, and ventilation can be conducted without air conditioning. Of course, ventilation is referred to here It doesn't have to be completely opened for natural wind to blow. Daily life experience tells us that if the humidity of natural wind is too high, the more it blows, the more wet it will be, and it will not be dry.
Purple sand container (pottery pot)
Purple sand utensils have always been accompanied by tea, usually we make tea, the best tea set should also be purple sand tea set. Purple sand teaware has its air permeability, and the better it is used. It is also the best container for storing Pu'er tea. However, the cost of purple sand jar is higher now. If you think the purple sand container is more expensive, you can use the pottery pot, which is less expensive than the purple sand container. Of course, the effect will be worse, but this is enough for ordinary collectors.
When using these containers, it is very important that the newly purchased containers must be cleaned, and the pollution source of the containers should be removed first. The method can be repeatedly cleaned with water and hot water, or with some low-grade tea boiled water, washed and dried. After putting tea, you can also put some bamboo charcoal in it, and then put tea. When putting tea, you can remove the shell of bamboo shoots on the package (bucket package) of tea and put it in the unit of cake (brick).
Cartons:
For the family individual tea, in fact, using cartons is the most practical method. Although the advantages of cartons for storing tea are not as good as purple sand containers, their advantages are also very obvious. On the one hand, cartons are relatively easy to get but free of charge; on the other hand, cartons are also convenient to store at home, which takes up less space.
When storing Pu'er tea in cartons, you should also pay attention to the peculiar smell of the cartons. Therefore, the original use of the cartons should be clearly understood. If there is a peculiar smell, it is better to store Pu'er tea after the odor has dissipated. It is recommended to store only pressed tea in cartons. It is recommended that the tea stored in cartons should be stored in the whole barrel instead of being disassembled. For those with only a few cakes, they can be sealed with paper letters before putting them away.
Original storage:
The original package of Pu'er tea is usually packed in bamboo baskets and cartons. If the purchased Pu'er tea is taken as a whole, it is very simple to store it in the original package.
Storage details of Pu'er tea:
1. Go and buy some wooden frames, or boards. The height of the wooden frame should be 10 cm high, and the stacking height of the boards should also be 10 cm. Store the tea on a wooden board or off the floor.
2. Buy a few kilograms of charcoal, conditional to buy bamboo charcoal, unconditional to buy ordinary charcoal can. In the wet season of every year, take half a kilogram as a share, divide the charcoal into several parts, put them in different corners of the tea room, and take out the charcoal after the wet season. When the weather is good, take the charcoal to the sun for exposure and seal up, and then take it out for use in the next wet season.
3. In wet season, do not open windows. When it is sunny, open windows properly for ventilation. Try to avoid opening windows at night. In normal days, when it doesn't rain, every half a month, on a sunny afternoon, open the window and ventilate for about half an hour. If it's summer, it's better to open the window in the morning or evening.
4. If the annual wet season is particularly long area, you can use fresh-keeping paper to wrap the outside of the carton to isolate moisture.
5. If it is in the dry area of the north, we can consider putting a few pots of water in the tea storage space to adjust the humidity. But pay attention to change the water, to avoid the water stink.
The older the Pu'er tea is, the more fragrant it is. The premise is to have the right storage method. The essence of how to preserve Pu'er tea cake described in this paper can't be separated from three factors: circulating air, constant temperature and moderate humidity. These three factors are very important, I hope to help you who like to collect Pu'er tea.
