Iron kettle to make tea, can you drink the tea when it is black?

Boiling tea is both a simple and a difficult task. The simplicity is that you can boil the tea in a pot, but it is difficult to brew it deliciously.

When the water is boiling, you can turn off the power or fire source, if you continue to boil, the tea soup will only become thicker, which is like making strong tea, the higher the temperature, the longer the soaking time, the tea soup will become relatively thicker.

If you're a fan of strong tea, you might as well give it a try.

Therefore, when the water is boiling, you can pour out the tea soup, and the taste and aroma at this time are quite close to the general purple clay pot.

or the texture and taste of the cup brewed. At this time, the water temperature in the iron kettle is still at a certain degree of high temperature, even if it is no longer heated, you can still use the water temperature to slowly release the substance that the tea should have, probably as long as you master the time, it is actually quite easy to make tea. Some friends have encountered the problem of boiling tea black.

Generally, the reason why tea is boiled black is mostly affected by two factors: tea type or iron kettle. Because of the tannic acid in the tea leaves.

Iron ions with iron kettles.

combined, tannic acid is produced.

Iron. Note that this is not drinkable. In particular, the rusty part will be more obvious, and through the combination with tannins, the oxidized rust will be reduced to black iron tannin, and part of the rust will be dissolved. Therefore, it will be cooked with a strange color.

Therefore, when boiling tea, please try to avoid teas with a light degree of fermentation, such as green tea and high mountain tea.

Pu'er new tea, etc. Because the above teas contain high tannins, try to choose teas with a high degree of fermentation or heavy roasting, such as Tieguanyin.

Taiwanese old tea, aged Pu'er, Fu brick.

This phenomenon should be avoided.

If it is not because of the relationship between the tea species, it may be because of the relationship between the iron kettle, and sometimes it will be caused by the rust in the iron kettle, so please scrub and tidy up the rust inside, and then try to boil to see if the tea soup has any abnormalities, and then the reason for the possible impact is the acidified film in the kettle, or the enamel part.

Of course, not all teas are.

It is suitable for boiling, so you need to choose the factor of boiling tea.

1.Tea is better boiled than brewed.

Such as Fu bricks, Fu bricks are much better than soaking in terms of aroma and taste.

2.Bring out the final value of tea.

When it comes to good aged teas or Indian teas, some of my friends may be like me, collecting tea residues to squeeze out the last drop of essence. It can really be said that you can eat dry and wipe clean, and not a drop is wasted.

3.I want to be lazy.

Sometimes there will always be times when things are very busy, and I can't spare time to make a pot of tea, and I want to drink tea but I am too lazy to brew it, so at this time, it is the fastest way to throw the tea down and boil.

The iron kettle boiling tea is not drinkable, because at this time, the iron kettle has a certain reaction with the tea in the process of high temperature heating, and the tea also has certain impurities at this time, and the taste will be very poor, so it is recommended to use a casserole or some special purple clay pot to make tea.

The iron kettle boils tea, and the tea is blackened, and it can also be drunk.

Tea contains tannic acid, which reacts with iron to form ferric tannic precipitate, which is blue-black, cannot be absorbed by the human body, is non-toxic, and can be drunk. Sometimes, when you cook food that contains tannic acid in an iron pot, it will also turn black, but there is no problem with eating it, such as mung bean soup cooked in an iron pot.

It's best not to drink it, the iron kettle will rust after a long time, and the tea brewed out will naturally not be transparent, and drinking it will also be harmful to human health, so don't drink it.

Summary. The black ones are tea stains, and the cleaning method is as follows:

Put the juiced lemon zest into a teacup, add some warm water, and wash it off once in a few hours to remove the dirt.

Wipe the inside and outside of the teacup with toothpaste once, and then wipe with a loofah tendon or sponge.

Yellow tea stains on a teacup can be rubbed with a soft cloth dipped in a little salt or alkali powder, and then washed with soapy water.

If it is a metal tea shelf, it will become jet black due to tea dirt, and if it cannot be washed off with a medium-sized detergent, it can be easily removed by soaking it in vinegar or soaking it with bleach.

To remove small pieces of tea stains, you can soak them in a solution of bleach or cleaning powder and leave them overnight to remove them.

The iron kettle boiling water to make tea will turn black.

The black color of the tea boiled in the iron kettle is due to the chemical reaction between the tea and the inner wall of the iron kettle. A substance called iron tannic acid is formed. The black ink we usually use is actually iron tannin.

The tannic acid in the tea will react chemically with iron, so the tea soup will be black, the iron kettle is suitable for boiling water, and the water boiled in the iron kettle can make the tea exude its original taste.

How to deal with this will not be blackened.

I just boil the water to make tea, and then the tea soup will turn black.

The black ones are tea stains, and the cleaning method is as follows: put the juiced lemon peel into the teacup, add some warm water, and wash it off once after a few hours, and the dirt will be removed. Wipe the inside and outside of the teacup with toothpaste once, and then wipe with a loofah tendon or sponge.

Hello, dear, you can't drink. The iron kettle is made of cast iron, and there are pores on the inner wall, and the color of the tea will gradually deepen after it has been left for a long time. The blackening of tea boiled in an iron kettle is mainly due to the tannin in the tea leaves oxidized with the iron ions released by the iron kettle at a high temperature, and the iron tannin is black, so the tea becomes black.

The principle is usually used to cook tea eggs in an iron pot, which is also black, so the iron kettle is still very good, which can soften the water quality, supplement ferrous ions, and the style is changeable and beautiful, and it also has cultural heritage and collection value, but the uncoated iron kettle is suitable for boiling water, not suitable for boiling tea.

Iron kettles are made of pig iron and have pores on the inner wall, so they are also called breathing iron. As we all know, the color of tea will gradually deepen after a long time. Boiling tea in an iron kettle turns black, mainly because of the tannins in the tea leaves.

The iron tannin obtained by oxidation with the iron ions released by the iron kettle at high temperature, and the iron tannin is black, so the tea becomes black.

The principle is similar to how everyone usually cooks tea eggs in an iron pot.

It's also dark, and it's eaten as often, and there's nothing wrong with it, so you don't have to panic and be suspicious. The iron kettle is still very good, which can soften the water quality and replenish ferrous ions.

The style is changeable and beautiful, and it also has cultural heritage and collection value, but the uncoated iron kettle is suitable for boiling water, not for making tea.

After reading it, the question is, what if you want to make tea in an iron kettle?

Method 1: Raise an uncoated iron kettle, the best is to clean water, followed by spring water, use these two kinds of water to raise an iron kettle, the fastest formation of scale. When your iron kettle has a protective film, it's time to make tea.

Method 2: Buy a reliable enamel.

The iron kettle of the inner tank (it must be an enamel inner tank, not an inferior coating on the market). Enamel is the ancient Chinese traditional craft enamel.

You can't use an iron kettle to make tea, because the iron kettle for making tea contains rust, and the tea will turn black when you make tea, which will affect the taste of the tea.

The cast iron kettle will turn black when making tea, mainly because the iron ions in the cast iron kettle react with the alkali in the tea when making tea, making the tea black.

Tea is rich in tea polyphenols, which chemically react with iron and turn black.

Summary. Let's take a look at the reasons why the tea will be boiled black: most of it is affected by two factors: the tea type or the iron kettle.

Let's take a look at the reasons why the tea will be boiled black: most of it is affected by two factors: the tea type or the iron kettle.

Because the tannic acid in the tea leaves, combined with the iron ions of the iron kettle, iron tannin is produced.

Note that this is not drinkable. In particular, the rusty part will be more obvious, and through the combination with tannic acid, the oxidized rust will be reduced to a black tanning beam with high acid iron slag, and part of the large scale rust will be dissolved. Therefore, it will be cooked with a strange color.

Therefore, when boiling tea, please try to avoid teas with a light degree of fermentation, such as: green tea, high mountain tea, Pu'er new tea, etc. Because the above teas contain high tannins, try to choose teas with a high degree of fermentation or heavy roasting, such as:

Iron Annihilation Liang Guanyin, Taiwanese old tea, aged Pu'er, Fu bricks, etc., should be able to avoid this phenomenon.

If it is not because of the relationship between the tea species, it may be because of the relationship between the iron kettle, sometimes because of the rust in the iron kettle (especially a large amount of rust), so please brush the rust inside the scrub first, and then try to boil to see if the tea soup has any abnormalities, and then the reason why the chaos may affect is the acidified film in the pot, or the enamel part. Of course, not all teas are suitable for boiling, so you need to choose the factors for boiling tea.

The blackening of the iron kettle is mainly because the iron kettle you buy is uncoated, and the iron ion kettle released by the iron kettle reacts with the tannins in the tea leaves, making the tea color black. Therefore, generally speaking, it is recommended that you boil only water in an uncoated iron kettle. You can cook a few dishes and try it.

Simple, the cover does not have heat dissipation holes, look for it, cover the eye, and straight.
