Tannins are molecular compounds called polyphenols, grape varieties, weather conditions, sunlight, and oak selection. There is a difference in the structure of polyphenols. And what we can feel in wine is the feeling of subtlety. or the hardness of the tannin itself

What is Tenin?

Tenin is a group of chemicals that exist naturally It is found mainly in plants. It is found in the bark of the tree or the leaves of the tannins in grapes. They are found in the bark, seeds and stalks and oak barrels used to ferment the wine. It also contains tannins. It is said to try chewing on the seeds of grapes. will know the feeling of perception of tannin.

The tannins that grapes produce It serves to protect the grapes from extreme weather conditions, such as extreme heat or cold, by the intensity of light. and climate change Will greatly affect the production of tannins in grapes, for example, grapes planted on slopes or hills will receive more light than grapevines. cultivated in flat areas or as the temperature gradually increases or decreases (streaming), tannins will be improved with quality. and more refined than grapes subjected to fluctuating temperatures.

Red wines are usually high in tannins. caused by the aging of grape juice that has peels in it tannins in the bark So mixed with wine, so it tastes more astringent than white wine. Especially wines made from grape varieties Nebbiolo (Nebbiolo) red grape variety of Italy. which is spicy, astringent and highly acidic, etc.

Type of tann:

There are two types of tannins:

• Condensed tannins (condensed tannins), also known as pro anthocyanins. (proanthrocyanin) or flavan-3-ols
• Hydrolyzed Tannins (Hydrolysable tannins) are tannins that can be broken down into smaller molecules such as glycosylated gallic acids, catechin, gallo catechin, epicatechinn, epigallocatechin, kaempferol, querectin, etc.

How is Tannin in wine?

Tannin or Tannin is a term used by wine drinkers. to explain A bitter, tart, or tart feeling you can feel after drinking the wine. which this bitterness obtained from the bark and the grape seed that was fermented in the wine making process make grape juice It has a slightly bitter taste along with it.

Additionally, the longer the bark, stalk, or seed is incubated in the grape juice, the more distinctive its character becomes. Even if it sounds bitter provoke the tongue But it’s Tannin. that helps keep the wine balanced and more complicated and makes the wine even more unique. and live longer

What are good tenses and bad tenses?

Lots of tennis doesn’t always mean good. More importantly, the quality of the tannin and its texture are important to indicate the quality of the tannin, such as softness, etc. When a wine contains the right amount of tannin, it is called “grippy”. The so-called “green” tannin is slightly bitter and astringent, but if the tannin is of good quality. What people consider to be “Polished” or “elegant” tans, what you need to notice in your tans are:

• to the touch, reaching tannins immediately or gradually
• that agent drown out the wine or to pair with wine
• That tannin gives a soft or strong flavor.

The feeling of tannin: How is it when you drink red wine?

• Very astringent or less astringent

Tannins are similar in structure to wines such as alcohol, meaning they should appear to be present, but not to surpass their freshness. and the fruitiness of the wine. When red wine is new will be dark red Tannins will remain astringent or green to bitter. As red wines are ready-to-drink, red will weaken and tannins will reduce their astringency until they become soft and smooth. Let acidity and fruitiness shine through. Until the end of age, the color of the wine will be a light orange shade. The tannins are bad? The wine is flat, bland and lacking in flavor.

• The coating remains in the mouth or not at all.

After swirl of wine around the mouth. and swallowed or spit it out in the test case Look around the walls of the mouth, tongue, gums, and teeth to see how much “sticky” it feels. Compare this feeling to drinking white wine, rosé wine, and red wine, in order.

Important steps in making red wine It’s up to management to have the right tannin levels. Because it will affect the quality and character of the wine. Red wine is fermentation and maceration. Grape juice is fermented along with the rind and seeds, or possibly with the stalk. The tannins obtained from the bark, seeds and stalks are also different. make color from bark and tannins are released in this fermentation process by time and technique in the fermentation stage. will be a variable in extracting the color and the amount of tannin out which alcohol occurs It will also stimulate the release of more tannins.

• Meticulous or harsh

Sometimes, after swallowing the wine, we feel that there is no tannin. or have less tannin But then there was a sticky feeling in the mouth after that. This doesn’t mean that the wine doesn’t have tannins, it’s because of the fineness of the tannins. that we may not be able to touch at first; on the contrary, if tannins have a large structure or less resolution We can feel it almost as soon as the wine enters the mouth.

Does tannin help in the aging of wine?

Most white wines mature well. Without tannins, red wines. Wines with a lot of tannins will age better than the tannins in the wine. have small molecules Over time, these tannins will begin to come together and build larger structures This will reduce the surface of the tannins. Gives a soft touch. and reduce the astringency of the wine, however, if the red wine It has a very strong tannin structure. And unbalanced, aging does not help the astringent taste disappear.

The benefits of tannins

Tannins are substances that belong to the group of compounds, polyphenols, chemical compounds whose main properties are antioxidants. help prevent inflammation and may help fight cancer Eating foods high in tannins thus helping to neutralize free radicals One of the major problems that lead to the degeneration of cells in the body and may lead to cancer Antioxidants such as tannins can also help prevent and reduce inflammation This makes the wound heal faster as well.

In addition, one recent study found that Tannins have anti-fungal properties. And various bacteria have made in the leather industry. Therefore, tannins have been used to dye the leather to a darker brown color. and help kill fungi or various bacteria that may be in the leather This makes the leather more durable and beautiful in color.

Caution about tannins

Tannins may be beneficial to health. But eating foods that are high in tannins especially eating too much It can lead to the following harmful effects:

• Reduce the absorption of nutrients

It was reported that Eating foods high in tannins May result in the body having a lower growth rate. consume less food And get less energy from food because of the tannins. May reduce the absorption of various nutrients in food, especially iron, by binding to these nutrients. making it more difficult for the body to absorb and use Although reducing the absorption Maybe not enough to cause harm. But for those who have problems with malnutrition before. May cause the problem to increase even more than before.
