How to distinguish real tea from fake tea? How to distinguish real tea from fake tea?

Real tea and fake tea, for people with certain practical experience, as long as they pay more attention, it is not difficult to distinguish. However, sometimes the raw materials of fake tea are mixed and processed together with the raw materials of real tea, which increases the difficulty of identification. Real tea and fake tea can generally be identified by sensory evaluation.

That is, the use of vision, taste and other organs to judge the authenticity of tea by seeing, smelling and tasting the inherent color, aroma, taste and shape characteristics of tea. When identifying, usually first hold a handful of dry tea with both hands and put it on the tip of the nose, take a deep breath, and smell the smell of the tea leaves. Those who have the inherent fragrance of tea are real tea; Anything with a green smell or other peculiar smell is fake tea.

If a small amount of tea leaves is taken and roasted over fire, the smell of real tea and fake tea is easier to identify. Secondly, it can be distinguished by the color of the tea leaves. Grab a handful of tea leaves and put them on a white porcelain plate, spread out the tea leaves, and observe carefully, if the green tea is dark green, the black tea is black, and the oolong tea is dark green, which is the true color of the tea.

If the color is messy and not coordinated, or inconsistent with the original color of the tea, it is suspected of fake tea. Third, if it is difficult to judge the smell and color, then a small amount of tea can be put into the cup, brewed with boiling water, and the soup can be evaluated to further identify the color, aroma, taste and shape of the tea, especially from the tea leaves. Although the size, color and thickness of tea leaves are different, and vary according to the variety, season, age, origin conditions and agricultural technical measures; The shape, margin, and tip of the leaves are also different depending on the tea tree variety, but some morphological characteristics are common to all kinds of tea, but not other plants, which is the main basis for distinguishing real tea from fake tea.

Real tea and fake tea can generally be identified by sensory evaluation. That is, the use of vision, taste and other organs to judge the authenticity of tea by seeing, smelling, touching and tasting the inherent color, aroma, shape and taste characteristics of tea.

1. When identifying, usually hold a handful of dry tea with both hands and smell the smell of tea. Those who have the inherent fragrance of tea are real tea; Any one with a fishy smell or other peculiar smell is fake tea. If a small amount of tea leaves is taken and roasted over fire, the smell of real tea and fake tea is easier to identify.

2. Secondly, it can also be distinguished from the color of the tea. Grab a handful of tea leaves and put them on a white porcelain plate, spread out the tea leaves, and observe carefully, if the green tea is dark green, the black tea is black, and the oolong tea is dark green, which is the true color of the tea. If the color is messy and uncoordinated, or inconsistent with the original color of the tea, it is suspected of fake tea.

3. True tea has obvious reticular veins, and the branch veins are connected with each other, which is turtle shell-shaped, bending upwards in two-thirds of the way, forming a wavy shape, and the leaf is raised. The veins of false tea leaves are inconspicuous or too pronounced, generally pinnate veins, reaching straight to the edges, and the inside of the leaves is smooth. The edges of the real tea are clearly serrate, the leaf stems are scarce, and the stems near the petiole are smooth and non-serrate.

Some of the edges of fake tea leaves are jagged, and some are not.

4. If it is difficult to judge the smell and color, then a small amount of tea can be put into the cup, brewed with boiling water, and the soup can be evaluated to further identify the color, aroma, shape and taste of the tea, especially from the tea leaves.

5. Although the size, color and thickness of tea leaves are different, and there are differences due to different varieties, seasons, tree ages, origin conditions and technical measures of the tea industry; The shape, margin, and tip of the leaves are also different depending on the tea tree variety, but some morphological characteristics are common to all kinds of teas and not possessed by other plants, which is the main basis for distinguishing real tea from fake tea.

1. Smell difference: first pick up the tea, smell the smell of the tea leaves, all those with a fixed aroma are real tea, such as fragrant, chestnut fragrant, floral, and all fishy miscellaneous or other peculiar smells are suspected of being fake tea.

2. Secondly, it is distinguished from the color of the tea: real tea has a fixed color, or emerald green or green brown, which is the true color of tea, if the color is messy and uncoordinated, there is a distorted hue, and it is suspected of being fake tea or adulterated tea;

3. You can also open the soup to identify: brew to make the tea look at the bottom of the leaf, where the leaf is triangular from the part, the leaf edge is distinct, the serration has glandular hairs, the serration near the base is thinning, the reticulated leaf vein, the main vein is obvious, the branch vein does not shoot directly at the edge, bends upwards at two-thirds of the way, connects the last vein is wavy, and the back has hairs for the straight tea.

How to identify real tea, fake tea?

In fact, as long as you look closely, you will always find some clues. This is because each plant has its own characteristics, which are manifested both in the external form and in the inner composition. The screening of real tea and fake tea can be "dry looking" and "wet looking".

1) Dry look. You can pick up a handful of dry tea with both hands and smell it with your nose. Where it has the inherent fresh fragrance of tea, it is real tea; Any smell with a fishy smell, a musty vegetable smell or other peculiar smell is a fake tea.

Then, you can also grab a handful of tea leaves and put them on a white plate or white paper**, and carefully observe them after spreading them evenly. For example, green tea is dark green, black tea is black and bright, oolong tea is dark and green, and white tea is silvery; Anything that is stagnant and green or cyan is suspected of fake tea.

2) Wet look. Take an appropriate amount of tea leaves (including suspected fake tea), put them in a cup, and open the soup for review, which can further distinguish real tea and fake tea from the aroma, taste, and color of the soup. If you look at it from the bottom of the leaf, you can better distinguish between real tea and fake tea.

The leaf edges of real tea are serrate, the upper half is dense and deep, the lower half is sparse and sparse, and the edge near the petiole is smooth and unserrated. Most fake teas have serrated or no serrated leaf margins.

The main vein of real tea is obvious, the leaf vein on the back is raised, and the branch vein is at an angle of 60°. Each branch is usually curved upwards at the inner third of the edge and joins with the previous vein to form a turtleshell-like reticulated vein. Fake teas tend to be veined, feathery, and go straight to the edge of the leaves.

Under the magnifying glass, the hairs on the back of the real tea leaves can be seen, which are perpendicular to the leaf surface of the empty punch, and the upper and lower halves are curved at an angle of 60°-90°. There are no hairs on the back of the fake tea leaves or hairs growing upright.

The real tea leaves are alternate in a spiral shape on the stem; Fake tea is often grown in clusters of opposite or several leaves.

In addition, professionals can also be asked to use chemical methods to determine the content of caffeine and catechins contained in it, and it can also distinguish real tea and fake tea.

It should be noted that tea made from buds and leaves plucked from non-tea plants is a fake tea. But this should be different from health care products, if ginseng tea made of ginseng leaves, Luo Dou Ji Jianbu hemp tea made of Luo Bu hemp leaves, mulberry tea made of mulberry leaf buds, as well as eagle tea, persimmon leaf tea, eucommia tea, wolfberry tea, stevia tea, etc., as well as tea mixed with different quantities of medicinal plants to make tea, such as glutinous rice tea, ** tea, youth anti-aging tea, etc., can not be confused with fake tea.

There are many tea quality problems on the market, and there are many fake and shoddy teas that often fool consumers

Step Method.

Take a look. The new tea leaves are tender green, the old tea leaves are dark green, the leaf margin is serrate, there are 16 to 32 pairs of teeth, the leaf end is concave, its young stem is oblate, the leaf back has white fluff, the shape is tight and thin, the delicate tea contains tendon stalks, the color is yellow-green, clean and uniform, and the flowers are dry and yellow-white; Fake tea leaves, without the above obvious characteristics, the color is sluggish, look at the water color, the color of the bottom of the leaves is neither as red and bright as black tea, nor green tea.

Second burning. Take a few pieces of tea leaves, light them with fire, the real tea leaves have a rich aroma, pinch the ashes with your fingers and smell them, you can smell the fragrance of tea; Fake tea leaves have a peculiar smell but no tea aroma. It is best to compare it with ** tea leaves and tea leaves to be identified at the same time.

Three bubbles. Take a handful of tea leaves to be identified and real tea leaves, brew them twice with boiling water, and take a closer look at the soup. Soak for 10 minutes each time, and after the leaves are fully soaked, put them in two white porcelain water trays, and carefully ** leaf shape, leaf veins, serrations and other characteristics.

True tea has obvious reticulate leaf veins, the main vein directly shoots at the apex, and the lateral veins extend to the leaf margin 2 3 and then bend upward, which is arc-shaped and united with the upper branch veins. The underside of the leaf is hairy, the leaf margin is prominently serrate, and the base is sparsely serrate. The leaf veins of fake tea are not obvious, and the lateral veins generally hit the edges directly, and some have white hairs on both sides, and the leaf edges are serrated, or the serrations are coarse.

There is no real or false tea, only good and bad. If you have to say whether it is true or false, like Wuyi rock tea, some of them are outside the mountain tea in Jian'ou, and the difference between them and the Zhengshan tea in Wuyi Mountain is big. Waishan tea has a muddy taste and a bitter taste, but Zhengshan tea has the inherent fragrance of tea, mellow, and fragrant on the teeth and cheeks.

Distinguish between good and bad tea.

One look: look at the shape and color of the tea. The color of good tea leaves is basically emerald green, and the bar shape of the bud head is relatively uniform. In addition, special attention should be paid to whether there are old or dead leaves in the tea, if there are, the quality of the tea is average.

Second smell: If the tea looks good, then you can pick it up and smell it. Generally, good tea leaves will smell a pungent fragrance; Poor quality tea leaves will smell musty, as if they have been stewed.

Three bubbles: Although the tea leaves on the market now look good in color, it is possible that some chemical raw materials have been added during the production process. Therefore, when buying tea, consumers had better brew it and taste it.

Under normal circumstances, the tea brewed with good tea leaves is very clear, and the opposite is cloudy. Of course, it is also necessary for consumers to taste the tea after brewing it. If the tea you drink is refreshing and moistens your throat and leaves a fragrance on your lips and teeth, then you are generally buying good tea.

On the contrary, if you drink it bitter and numb in your mouth, it is likely to be summer tea, and the quality will not be too good.

Answer 1, first of all, we should look at the shape of the tea, the tea has loose tea, there is pressed tea, you know, the formed tea is mostly white tea and black tea, if the tea is loose tea. We can judge the dry tea according to its color and shape. Most of the green tea is yellow-green with emerald, and the black tea is mostly reddish-brown, and the type of tea can be basically judged according to the shape and color of the tea.

2. Look at the color of the soup, if it is not possible to judge according to the dry tea, we have to judge by the color of the tea soup, brew 3 grams of tea with a review cup for 5 minutes and then open the soup, observe the color of the tea soup, black tea is mostly red, green tea is mostly yellow-green, yellow tea is mostly yellow, white tea is mostly light yellow, and the tea soup needs a certain evaluation basis.

3. Smell the aroma, after reading the color of the tea soup, you can smell the aroma, and the aroma can be divided into cold smell, hot smell, warm smell, and can be judged according to the aroma of the tea soup. The freshness of white tea is its greatest characteristic.

4. After smelling the aroma, you need to taste the taste of the tea soup, taste the taste, the types of tea are different, the taste of the tea soup is different, or mellow, or strong, or peaceful, the taste of green tea is mostly fresh, black tea is mostly mellow, and white tea is mostly umami-based. We can distinguish the type of tea according to the taste of the tea soup.

5. The last step is to look at the bottom of the leaf, pour the bottom of the leaf into the bottom of the leaf, and observe the size, age, color, crushing and other characteristics of the bottom of the leaf. The bottom of different tea leaves is also different, we can distinguish the type of tea according to the bottom of the tea leaves, and the softness and hardness of the bottom of the leaves can also reflect the processing of tea.

Okay, I'll soak it up for you to see.

Fake, it is also tea, that is, the quality is good or bad.

Look at what kind of breed it is, different varieties are not the same.
