【Private message】I try to drink random tea samples
In recent years, Yunnan has expanded its tea categories by relying on its abundant tea resources, among which Yunnan white tea has grown from its rise to popular tea, with a short period of time, and now its popularity in the market is increasing.
Therefore, there are many tea friends who have a lot of questions when they see the rapid development of white tea, and the frequency of "one year tea, three years of medicine, and seven years of treasure" is higher. Bang Yue also received a similar question: Why does white tea for 3 years have medicinal aromas, where does the medicinal fragrance come from, is it bad?
Before understanding why white tea has medicinal aromas, we must first understand the aroma components and types in tea.
Although there are hundreds of aromatic substances in tea,
But it can be roughly divided into 4 categories:
1． , such as -3-hexenol (also known as cyanol), trans-2-hexenal, jasmonone and other aromatic substances, but such substances mostly appear in black tea.
2． , mainly monoterpenes, including linalool, geraniol, neroli, etc. and their acetates, such as acetic agarwood, geraniol and the like.
3． , there are mainly phenylacetaldehyde, benzaldehyde and other compounds.
4． , mainly pyrazine, pyridine and other compounds.
In addition to aromatic substances can produce aroma, some amino acids such as glutamic acid, alanine, etc. also have floral fragrance; some sugars have a sweet fragrance; sugar and pectin will have caramel aroma after coking.
In addition, because Yunnan is located in the plateau area and has a high altitude, the tea varieties belong to the Yunnan large-leaf species, so there will be different varieties of incense, regional incense and so on.
3 years old white tea,
How is medicinal incense produced?
First of all, during the withering process of white tea, the content of aromatic materials increases with the degree of wilting, such as carbonyl compounds, n-hexanol, nemonol and the like.
Secondly, when the water content of white tea in the storage process is less than 5%, it is resistant to storage, although the aroma change is small, but it will also increase with the increase of storage time, aromatic substances will continue to decompose under the action of active enzymes, and then react with other inclusions, polymerize, and form a new composite substance, medicinal fragrance is the compound incense formed in the transformation process.
White tea aged for 3 years has a medicinal aroma,
Is it good or bad?
If during storage, the tea leaves do not absorb other odors, or are not affected by the high temperature and high humidity environment, the production of medicinal aroma under normal storage conditions is a normal phenomenon after white tea storage, and whether it is Yunnan white tea or white tea from other provinces, the better quality white tea will produce medicinal aroma after storage, so you can drink with confidence.
Take it for example, the thick and sweet tea soup with magnolia flowers, white flowers and wisps of medicinal fragrance stretches in the mouth, elegant tea rhyme reminiscent of classical beauty, and the pleasant medicinal fragrance brought by time can not help but amaze people, time has passed more than 3 years.
Since the tea leaves are properly stored,
Why is medicinal incense still questioned?
One of the main reasons is because Yunnan white tea has appeared for a short time, it is indeed not as long as the history of Fujian white tea, and, in addition, because ordinary tea friends have led to misconceptions, so it should be a problem that the entire industry needs to face and solve.
Of course, the earliest form of tea began with medicinal use, which is visible from the beginning:
Secondly, some teas are also used by traditional Chinese medicine to alleviate certain diseases, so tea also has medicinal value, and it is not surprising that it can produce medicinal fragrance.
With the increase of storage time, white tea not only shows the appearance of old age, but also the color, fragrance and taste have a significant sense of vintage, and its wonderful transformation power has been discovered very early, although it is not clearly recorded, but it is passed down in oral form in the folk.
Therefore, "one year of tea, three years of medicine, seven years of treasure" is not an empty wind, but a fact that people have observed for a long time and combined with reality.
If your white tea has a medicinal aroma, don't panic, don't be busy throwing it away. You can make a preliminary judgment from the appearance and aroma, determine that it is the normal storage of the transformed tea aroma, and then brew the tasting to further identify, if the aroma and taste are not abnormal, then the tea can also be tasted and stored.
