Differences between green tea and Pu-erh

There are many types of tea. Green tea, Pu-erh tea and other presumably tea friends are familiar, and the difference between green tea and Pu-erh tea is actually quite large. Let's take a look at the specific differences between green tea and Pu-erh tea for reference only.

The difference between green tea and Puer tea is mainly seen in the following five points:
 
1. Differences in growth environment.
 
The ecological environment of Pu-erh tea is high altitude and low latitude, subtropical warm and humid climate, sufficient rainfall and sunshine, four seasons like spring, mild climate, low acid soil with PH value of 4.5 to 6.5; and the ecological environment of green tea is low altitude warm and humid climate It has distinct seasons throughout the year, long illumination time, and high light intensity, which is not conducive to the metabolism of nitrogen-containing compounds in the bud leaves, and the absorption and synthesis of light quantum, so the content of chlorophyll, carotene, protein and amino acids in green tea is significantly less than Puer tea.

2. The difference in characteristics.
 
Green tea is acidic tea. Due to excessive intake of high-cholesterol and high-calorie foods, there are more and more people with acidic constitution. Therefore, excessive consumption of green tea will aggravate the stomach and body irritation, causing a series of adverse reactions; The content of green tea is much less than Pu-erh tea, so the bubble resistance is much worse than Pu-erh tea. Pu-erh tea is a kind of alkaline tea. After the scientific fertilization process accelerates and shortens its post-fermentation process, a large number of beneficial bacteria are produced through the metabolic process of enzymes and polyphenols, forming a smooth and mellow taste. The mild tea nature will not cause any adverse reactions to the human body, and it is suitable for drinking Pu-erh tea regardless of age.
 
3. The difference in production process.
 
Green tea is produced by killing green tea at a high temperature of 300-400 degrees, completely killing the tea, and then completely removing water from the tea leaves in the baking process. Pu-erh tea is made by killing green at a low temperature of 70 to 85 degrees, retaining the activity of the tea body, and then using the sun-drying process to remove about 90% of the water in the tea leaves. Because the tea body of Pu-erh tea also contains about 12% Water, so Pu-erh tea is post-fermented tea, while green tea is completely unfermented tea.

4. Differences in storage methods.
 
Since green tea no longer has vital signs, there are no specific requirements for its storage, as long as there is no smell, Pu-erh tea should be placed in a well-ventilated place with no smell and humidity of 60 %, And stored in a place without direct sunlight, so as to ensure the quality of Pu-erh tea.
 
5. Differences in shelf life.
 
Generally, the shelf life of green tea is 2 years, and its quality will decline with the extension of time. While Pu-erh tea is a post-fermented tea, which has the characteristics of "more aging and more fragrance". It is reasonable, and its quality will increase and optimize with the extension of time.
