How to identify tea leaves as new tea, how to identify new tea and fresh tea leaves

You can distinguish old tea from new tea according to the color of the tea leaves. Generally speaking, the green tea is verdant and turquoise, and the soup is yellow-green and bright; The black tea is dark in color, and the soup color is red and orange, which is the sign of new tea.

You can distinguish new tea from old tea by aroma. With the extension of time, the aroma of tea will change from high to low, and the fragrance will change from the fresh fragrance of new tea to low and turbid.

You can also distinguish new tea from old tea from the taste of tea. No matter what kind of tea, the taste of Dafan's new tea is mellow and fresh, while the old tea is light and unpleasant.

When buying tea, how do you distinguish between new tea and old tea? Listen to what the tea art teacher has to say.

The characteristics of new tea are that the color, smell and taste are fresh and refreshing, the water content of new tea is low, the tea is dry and hard and brittle, the fingers can pinch it into powder, and the tea stem is easy to break.

However, the aged tea that has been stored for more than one year has a dull yellow color, a low aroma, a bland taste, and a nasty stale taste when drinking. Aged tea is stored for a long time, the water content is high, the tea is soft, the hand pinching can not become a powder, and the tea stalk is not easy to break.

1. Color viewing method: the color of the new tea is fresh and the greenness is obvious, while the old tea is dark and black, and the greenness is obviously worse than that of the new tea.

2. Taste identification method: the new tea has a strong fragrance, fresh and natural, and the old tea has a light fragrance and lacks umami. Individual merchants' old tea can be smoked with fragrance, but the fragrance of such tea is not pure enough, as long as it is careful, it can generally be distinguished.

3. Dry and wet distinguishing method: the new tea has just been listed and just fried, unless the merchant is fake, it is generally dry. Due to the long time of placing the old tea, the influence of moisture re-emergence will make the tea feel slightly heavier, and rubbing it by hand does not have that kind of light and crisp friction sound.

4. Distinguish the fine method: many green teas can form natural fine hairs after being fried, such tea is generally the tip of the bud, the price is relatively expensive, the taste is refreshing, sweet and fragrant, and it is a famous product in tea. However, if it is left for a long time, the fine hairs will condense into small balls that are not easy to detect, and the color and fragrance of such tea leaves will be greatly discounted.

The fine hairs of the new tea are naturally attached to the leaves and have not yet fallen off.

The new tea color and fragrance are good, the old tea color and fragrance are not good, and the tea that has been placed for a long time is not only not good for the human body, but will produce ***, such as astringent taste, stomach distension after drinking, and so on. So how do you tell the difference between old and new tea? 1. It is the color observation method

The color of the new tea is fresh and the greenness is obvious, while the color of the old tea is dark and black, and the greenness is obviously worse than that of the new tea. 2. It is a dry and wet distinguishing method: the new tea has just been put on the market and has just been fried, unless the merchant is fake, it is generally dry.

Due to the long time of placing the old tea, the influence of moisture re-emergence will make the tea feel slightly heavier, and rubbing it by hand does not have that kind of light and crisp friction sound. 3. It is a taste identification method: the new tea has a strong fragrance, fresh and natural, and the old tea has a light fragrance and lacks umami.

Individual merchants' old tea can be smoked with fragrance, but the fragrance of such tea is not pure enough, as long as it is careful, it can generally be distinguished. 4. It is the method of distinguishing fine hairs: many green teas can form natural fine hairs after being fried, such tea is generally the tip of the buds, the price is relatively expensive, the taste is refreshing, sweet and fragrant, and it is a famous product in tea.

However, if it is left for a long time, the fine hairs will condense into small balls that are not easy to detect, and the color and fragrance of such tea leaves will be greatly discounted. The fine hairs of the new tea are naturally attached to the leaves, and they have not yet fallen off, and if you carefully distinguish them, you can distinguish the difference between the old and new teas.

1. Appearance: All kinds of tea have specific shape characteristics, some are like silver needles, some are like melon seed slices, some are like round beads, some are like peacock's tongues, some leaves are loose, and some leaves are tightly knotted. The leaves of roasted green tea are tightly knotted and straight.

Famous and high-quality teas have their own unique shapes, such as the shape of Wuzi Xianhao is characterized by "slightly flattened and straight". Generally speaking, the shape of new tea: bright strips, uniform size, thickness, and length are of the highest grade; The cord is dull, the appearance is not tidy, and there are even tea stalks and tea seeds.

Fine, many buds, sharp sprouts and high tenderness; Coarse pine, many old leaves, and low tenderness of leaf fat bulges. Flat tea is better for flat and smooth, and coarse, dry and short for second; The strip tea is better if the strip is tight, straight, and even, and the one that is rough, twisted, and short is secondary; Granular tea is better for those who are perfect and fruitful, and those that are loose and lumpy are secondary.

2. Look at the color: The color of new tea is generally fresh and pleasing to the eye, or tender green or dark green. Green tea is good for its emerald color, fresh and lively; The color of fried green tea is gray-green with a slight luster.

The color of some tea leaves is withered, dark and brown, indicating that the inner quality of tea leaves has different degrees of oxidation, and this kind of tea is often aged tea; If there is an obvious focal point on the tea leaves, bubble spots (black and clear and sleepy or dark sauce spots) or the edge of the leaf is burnt, it means that it is not good tea and is not a good tea; If the color of the tea is mixed, and the contrast between the shades of the color is large, it means that the tea is sandwiched with yellow, and the old leaves even have aged tea, and such tea is not a good tea.

3. Smell the aroma: New tea generally has the fragrance of new tea. Good new tea, the tea aroma is particularly obvious.

Nu Skin green tea has a pleasant aroma, and its aroma has a light fragrance, strong fragrance, and sweet fragrance; The higher the quality of the tea, the more intense and tangy the aroma. Chewing or brewing, green tea is sweet and fragrant, if you can't smell the tea fragrance or smell a green astringent, coarse and old, burnt gas, it is not a good new tea. If it is an aged tea, the aroma is weak or has an aged smell.

4. Tea taste: The tea soup is sweet and fresh after the entrance, rich and mellow and refreshing, and it is best to leave a sweet taste in the mouth; Usually take a small amount of samples to brew and observe, good green tea, the soup color is green and clear, the tea leaves are astringent, then fragrant and sweet, and with chestnut fragrance.

5. Pinch dry and wet: Pinch the tea leaves with your fingers to judge the dryness and wetness of the new tea. New tea must be dry enough to be shelf-stable.

The moisture content of damp tea is high, which will not only seriously affect the color, aroma and taste of tea, but also be prone to mildew and deterioration. Judging that the new tea is not dry enough, you can take one or two pieces of tea with your thumb and index finger and pinch it a little harder, and it can be pinched into powder is dry tea, which can be bought; If it is not pinched into powder, it means that the tea has been damp and has a high water content, and this new tea is easy to deteriorate and should not be purchased.

6. At the same time, to prevent shoddy, we will introduce the characteristics of several famous teas for reference when purchasing new tea. Meridian Green Tea:

The shape is compact, heavy, even, with sharp seedlings, the color is green, the aroma is tender and fresh, the high and refreshing long-lasting chestnut fragrance, the taste is mellow, the soup color is tender and green, and the bottom of the leaves is tender and green.

The first is to look at color. The color of green tea is verdant and turquoise, and the color of the soup is yellow-green and bright; The black tea is dark in color, and the soup color is red and orange, which is the sign of new tea. In the process of tea storage, some substances that constitute the color of tea will be slowly decomposed or oxidized under the action of light, gas and heat, such as the decomposition and oxidation of chlorophyll in green tea, which will make the color of green tea become gray and dull, and the increase of theabrownin will make the color of green tea soup become yellow-brown and lose its original fresh color; When black tea is stored for a long time, the tea polyphenols in the tea will be oxidized and condensed, which will make the color become gray, and the increase of theabrownin will also make the soup color turbid, and it will also lose the freshness of the new black tea.

The second is to smell the fragrance. Scientific analysis shows that there are more than 300 kinds of components that constitute the aroma of tea, mainly alcohols, esters, aldehydes and other characteristics. During the storage of tea, they can not only volatilize continuously, but also slowly oxidize.

Therefore, with the extension of time, the aroma of tea will change from strong to light, and the fragrance will change from the fragrance of new tea to low and turbid.

The third is taste. Because in the process of storage, the phenolic compounds, amino acids, vitamins and other characteristics in the tea constitute the taste characteristics, some decompose and volatilize, and some condense into insoluble substances, so that the effective taste substances that can be dissolved in the tea soup are reduced. Therefore, no matter what kind of tea, the taste of Dafan new tea is mellow and fresh, while the old tea is light and unpleasant.

1. Look at the degree of dryness and wetness of the tea: because the new tea has just been made, the water content is low, relatively dry, can be kneaded into powder by hand and the tea stalk is easy to break, while the old tea has been stored for a long time, the water content is higher and becomes soft.

2. Look at the color of the tea: the color of the new tea is bright and the old tea is relatively dull, in addition, in terms of fragrance, the aroma of the new tea is rich, the taste is mellow and fresh, while the old tea has a light fragrance and the taste is not as good as the new tea.

3. Tasting: The taste of new tea is fresh and thick, while relatively speaking, the old tea has an obvious sense of stale and thin taste.

How can you tell if it's new tea or old tea? Introduction Drinking green tea often still has many benefits for the body, so how to tell whether green tea is new tea or old tea? Tools Raw Materials Green Tea Method Step 1 1The new tea is simply relatively easy to break, and you can keep it in your hand and observe it.

1. Look at the color. During the storage process of tea, some pigment substances that make up the color of tea will change under the influence of oxygen and light, and gradually change from verdant green to grayish brown when new tea is fresh. Under normal circumstances, the color of new tea is bright green, shiny, green and distinct, tender green or dark green, the color of the brewed tea soup is turquoise, and the bottom of the leaves is bright green.

Aged tea is usually dark in color, dull, dark green or dark brown, the cross-section of the tea stem is dark black, the soup color is also darker and darker, theaflavins are further oxidized and polymerized, yellowish, and low transparency. There is also a simple way to take one or two pieces of tea leaves, pinch them slightly with your fingers, the new tea generally has a low water content, the tea leaves are loose, hard and brittle, and you can pinch them lightly with your fingers to form a powder. Aged tea is too long to rot because of cracking, long-lasting moisture absorption, generally the water content is relatively high, the tea leaves are soft and heavy, pinched with fingers can not be powdered, and the tea stem is not easy to break.

However, judging by color is not very safe, because some merchants will store the aged tea at low temperature. Under normal circumstances, if green tea is well sealed and placed in the freezer, and it is not turned over and opened during the period, then the color will still look as green as new tea if it is placed for a long time and then taken out.

2. Smell the aroma. New tea generally has a very fresh aroma, taking Longjing as an example, when the new tea is brewed in hot water, the aroma of bean, fragrance, chestnut and other aromas will float out at once, the aroma is overflowing, and the smell is rich and fresh; Aged tea will smell more dull, and if it is a poorly sealed tea, it will also be mixed with some peculiar smells. There are hundreds of aromatic substances in tea, and these substances will continue to volatilize during long-term storage.

Tea leaves also oxidize slowly. Therefore, after a long time, the aromatic substances in the aged tea gradually volatilize, the aroma begins to fade and become lighter, and the fragrance will also become dull and turbid from the fragrant fragrance when the tea is prepared in Xinqing. Usually aged tea will produce an unpleasant aging taste, which is often referred to as "stale taste", and even has a coarse or burnt atmosphere.

Some aged teas will be artificially incensed**, but the flavor of this tea is extremely impure.

3. Taste. No matter how good the tea is, only after tasting and comparing can we judge the quality of the tea. Therefore, before we buy tea, we can let the seller make a pot of tea, sit down and taste it carefully, and screen it by the taste of the tea.

New tea is freshly made tea leaves, and the taste is very refreshing, while the taste of old tea will appear lighter. The taste of new tea is fresh and sweet, sweet after entering the mouth, and the sweetness is more obvious; If it is an aged tea, the taste will lack freshness and will produce a "watery taste". This is because the main substances that determine the taste of tea are polyphenolic compounds, amino acids, caffeine, sugars, and vitamins.

In the process of storage, due to the oxidation and polymerization reaction of these substances in the tea, some insoluble substances in water are produced, so that the soluble active ingredients in the tea soup are reduced, and the taste of the tea leaves also becomes thin from mellow.

The difference between new tea and old tea can be started by looking at the color, smelling the aroma and tasting the taste.

1. Look, the new tea is fresh, hard and loose; Aged tea is constricted, dark, soft, and damp. From the gloss of tea, the appearance of dried tea is generally oily and fresh, the color is better for the good product, miscellaneous but not all of the defective products, and the fake and inferior old tea is gray and dark. Judging from the color of the tea soup, the tea soup brewed with new tea is clear.

The color of aged tea soup is gray and dull, dull and unclear or brown.

2. Smell, the fragrance of the new tea is fragrant, and the buds and leaves are stretched after brewing. Aged tea, on the other hand, has a low aroma and shriveled buds and leaves. Take a little tea and put it on the palm of your hand, and breathe in your mouth to make the tea leaves damp and exude aroma.

If it exudes a purple fragrance, musty smell, sour taste, rancid taste, etc., it means that it is aged or inferior tea.

3. Taste, the new tea tea soup has a strong and rich taste, mellow, and a fresh and pure fragrance that is not light for a long time; After drinking, the old tea soup not only does not have a mellow feeling, but even has a slight grass taste, bitter taste, sour taste and other peculiar smells.
