Puer Tea Sealed vs. Ventilated Storage Comparative Experiment
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… -
Specific Measures for Mechanical Tea Pruning
For tea trees of different ages, the methods of mechanical pruning vary. For young tea trees, the primary focus is on shaping pruning; for mature tea trees, light and deep pruning are predominant; and for old tea trees, rejuvenation pruning and stump cutting are mainly conducted. Generally, pruning around the time of Jingzhe (Awakening of Insects) yields good results. However, from an economic perspective, young tea trees should be pruned at the beginning of Lichun (Start of Spring), while other tea trees should be pruned after tea picking. Light Pruning Light pruning effectively promotes the sprouting and growth of tea buds. It also increases the density of productive branches, widens the tree canopy, and creates a favorable picking surface. For mature tea trees, light pruning should be conducted every two years, timed when the upper part of the tea tree stops growing. In regions prone to frost damage, pruning can be done half a month to one month before the spring sprouting of tea buds. For famous tea gardens, light pruning can be conducted after spring tea picking. During light pruning, hedging shears or pruning machines are primarily used to trim off about 4 cm of foliage and branches from… -
The Authentic Way to Enjoy Pu’er Tea
Tea enthusiasts who enjoy tea are certainly familiar with Pu'er tea, but not all may know how to fully appreciate it. Today, let's discuss the seven steps to enjoying Pu'er tea together. Step 1: Observe the Tea Mature production processes ensure consistency in the shape of the compressed tea cakes, which are evenly formed and tightly compacted. Since the introduction of electrostatic dust removal machines, contemporary Pu'er teas from reputable manufacturers do not contain foreign objects. However, before 2004 when these machines were not widely used, older teas might have some impurities as they were manually screened. The color of Pu'er tea can help distinguish between raw and ripe varieties: ripe Pu'er is dark brown, while raw Pu'er ranges from dark green (young) to brownish-red (aged), with loose or compact leaves that become dry and lustrous over time. Step 2: Feel the Tea Feel the compactness of the tea; a loosely packed tea will age faster under the same storage conditions compared to one that is more tightly packed. When breaking off a piece of the tea, check for consistency throughout – some teas have higher-grade leaves sprinkled on the surface for better appearance, while others use a uniform grade…- 2

Prevention and Remedial Measures for Drought Damage in Tea Gardens
To prevent drought damage in tea gardens and reduce losses in tea production, supplementary measures to replenish water and suppress evaporation can be taken before the onset of drought. These include irrigation to supplement water, loosening the soil and weeding, inter-row grass covering, etc., to maintain and regulate soil moisture and improve the microclimate around the tea plants, thereby enhancing the tea trees' drought resistance. Irrigation Replenishment Tea garden irrigation methods include furrow irrigation, sprinkler irrigation, drip irrigation, among others, each with its own advantages and disadvantages. Furrow irrigation is suitable for flat tea gardens and can quickly increase soil moisture levels, promptly rescuing drought-stressed tea trees, but it consumes a large amount of water, has a small impact on air humidity, and can lead to waste of water resources through surface runoff and deep seepage, as well as damaging some of the topsoil structure. Drip irrigation reduces evaporation and saves water, but it requires a higher initial investment and cannot effectively improve the microclimate of the tea garden. Therefore, in recent decades, sprinkler irrigation has been the primary method used for drought prevention and mitigation in tea gardens. Sprinkler Irrigation can not only increase soil moisture but also lower…- 3
