Black tea

There are two main types of tea: Assamese and Chinese. The first is named after the Indian province where it grows. Tea tree is a very hardy plant that can adapt to different climatic conditions. In addition, the plant is resistant to diseases and pests.

The second homeland of tea is Ceylon. This plant appeared there in 1824. The bushes were brought there from China.

Black tea is a product that is very popular in Russia. It, unlike the green variety, went through a long chain of preparation processes. It can be granulated, long leaf, packaged and tiled. Available with or without additives. The taste of black tea is slightly tart, without bitterness. Color orange or amber.

The most fragrant and delicious variety obtained from the apical part of the shoot. It consists of a bud and several unblown leaves. The drink made from old shoots is of low quality.

The quality of the variety directly depends on the conditions in which the plant was grown. This is the condition of the soil, climate, harvest season, and caring for the bush. For example, the climate of Assam is characterized by trees up to 18 meters high with large fleshy leaves, and in China shrubs up to 3 meters high with small glossy leaves grow.

Collection

tea leaves are picked by hand

As already mentioned, a high-quality variety requires young, tender leaves; they are collected by hand. This process requires special attention and dexterity. The collection is mainly done by women. At the same time, it is important to ensure that the old leaf does not get into the young leaves, because this will make the collection lower in quality.

The main trick of tea pickers is to pick the bud and the top 2 leaves at a time. This branch is called “flash”. In one day, on average, up to 50 thousand flushes are collected. The drink made from such leaves is called black long tea.

Leaves are collected three times per season. The first harvest takes place in March, when the buds on the bushes are just swelling. This tea has a floral aroma. The second harvest occurs at the end of spring. The drink made from such leaves is stronger and has a tart taste. The last collection takes place in October. The tea turns out softer, tastes like the first collection, but is somewhat richer.

What do you do with mature leaves? Are they really not used? Such leaves are used to make no less tasty and amazing tea– black dragon, or it is also called Chinese oolong. It is prepared slightly differently and occupies a place between black and green tea.

Production

black tea production begins with withering the leaves

Traditional and familiar black tea goes through several stages of preparation. The first is withering. At this stage, moisture is removed from the leaves, resulting in an increase in the concentration of dry matter in the plant. This is a kind of catalyst, as biochemical processes begin to proceed faster. During the withering stage, the leaf loses about 14% of its moisture. Compliance with humidity standards after the first stage is extremely important: the quality of the final product depends on it.

In addition, it is important to maintain certain temperature and humidity conditions when processing leaves. In countries with suitable climatic conditions, withering occurs naturally. In areas with colder climates, this process occurs when creating artificial conditions. But in any case, the final result of the first stage of processing should be High Quality. At the same time, the leaves are deprived of moisture, and the flush becomes elastic and soft.

The second phase of production is called curling. It is carried out manually or in special machines - rollers. As a result of this process, some of the juice is released from the leaves, and they themselves crumble.

The rolling step prepares the leaves for fermentation. They are laid out on a flat surface. In interaction with oxygen, an oxidation process occurs. It is important not to overcook the tea, otherwise it will be spoiled. As a result of this process, the leaves darken and become taste qualities, characteristic of a particular variety. Then they are dried and packaged in jars, packs, and filter bags.

Types and blending

There are many varieties of black tea

As mentioned above, there are four main types of tea:

long leaf (large and medium leaf),

The English breakfast is a strong, invigorating, rich drink.
Irish breakfast is a mixture of varieties, usually Assam. Strong, quite tart and aromatic tea.
Russian caravan – popular product in the West, but in Russia it is almost unknown. The name has been preserved since the times when goods from China were delivered by camel caravans.

Chemical composition

Half a century ago, it was believed that black tea contained about five chemical compounds. Many more groups of such compounds are now known.

Extractive substances. Their number depends on the age of the leaf. In young leaves the concentration of such substances is much higher.
Tannins. They occupy a third of the entire composition. These are tannin, catechins, polyphenols. Tannin gives the drink a more tart taste.
Essential oils. They are the ones who give the product its particular flavor.
Alkaloids are an important component of any tea. These include caffeine. Thanks to this substance, tea has a tonic effect. In addition, this caffeine is healthier for the human body than that found in coffee.

3. May Lower Bad LDL Cholesterol Levels

The body contains two types of lipoproteins that transport cholesterol throughout the body. One is low-density lipoprotein (LDL) and the other is high-density lipoprotein (HDL).

LDL is considered the “bad” lipoprotein because it carries cholesterol into cells throughout the body. HDL, meanwhile, is considered the “good” lipoprotein because it carries cholesterol away from your cells and into the liver for elimination.

When there is too much LDL in the body, it can accumulate in the arteries and cause waxy deposits called cholesterol plaques. This can lead to problems such as heart failure or stroke.

Fortunately, some studies have shown that drinking tea may help lower LDL cholesterol levels. One randomized trial found that drinking five servings of black tea per day reduced LDL cholesterol by 11% in individuals with little or no increased level cholesterol ().

Another randomized three-month study involving 47 subjects compared the effects of traditional Chinese black tea extract and placebo on LDL levels. The results showed a significant reduction in LDL levels in those who drank black tea compared to placebo, with no adverse effects side effects. Researchers concluded that black tea helped improve cholesterol levels in people at risk of heart failure or obesity ().

Summary:

LDL and HDL are two types of lipoproteins that carry cholesterol throughout the body. Too much LDL in the body can increase the risk of heart disease and stroke. Research has shown that black tea can help lower LDL levels.

4. May Improve Gut Health

Research has shown that certain types of bacteria in your gut play an important role in your health. This is because the gut contains trillions of bacteria, as well as 70-80% of your immune system ().

While some of the bacteria in your gut are good for your health, some are not. In fact, some studies have shown that the good bacteria in your gut may play an important role in reducing the risk of developing certain diseases, such as inflammatory disease intestines (IBD), type 2 diabetes, cardiovascular diseases, obesity and even cancer ().

The polyphenols found in black tea may help support gut health by promoting the growth of good bacteria and inhibiting the growth of bad bacteria such as salmonella ().

In addition, black tea has antimicrobial properties that help destroy harmful substances and increase populations beneficial bacteria and strengthening the immune system, which helps restore the mucous membrane of the digestive tract.

However, further research is needed before a firm conclusion can be made about the role of black tea and immune function ().

Summary:

The gut is home to trillions of bacteria and much of your immune system. The polyphenols in black tea, as well as its antimicrobial properties, may help improve gut health and immunity.

5. May Help Lower Blood Pressure

High blood pressure affects approximately 1 billion people worldwide ().

This may increase the risk of developing heart disease and renal failure, stroke, vision loss and heart attacks. Fortunately, changes to your diet and lifestyle can lower your blood pressure ().

The results showed that those who drank black tea had a significant reduction in systolic and diastolic blood pressure compared to the placebo group ().

However, research on the effects of black tea on blood pressure is mixed.

A meta-analysis of five different studies involving 343 participants looked at the effects of drinking black tea for four weeks on blood pressure. Although the results showed some improvements in blood pressure, the researchers concluded that the results were not significant ().

Daily use black tea, as well as some lifestyle changes such as , may benefit people with high blood pressure.

Summary:

High blood pressure can cause many complications. Regular use Drinking black tea may help reduce systolic and diastolic blood pressure, but research is mixed.

6. May Help Reduce the Risk of Stroke

Black tea is an excellent unsweetened drink that has been found to help improve the body's use of insulin.

One test-tube study examined the insulin-boosting properties of tea and its ingredients. The results showed that black tea increased insulin activity by more than 15 times. The researchers concluded that several compounds in tea showed improvements in insulin levels, particularly a catechin called epigallocatechin gallate (EGG).

In another study on mice, researchers compared the effects of black and green tea extract on blood sugar levels. The results showed that both lowered blood sugar levels and improved the body's sugar metabolism ().

Summary:

Insulin is a hormone that is released when you consume sugar. Black tea is an excellent unsweetened drink that can help improve insulin use and lower blood sugar levels.

8. May Help Reduce Cancer Risk

Another study analyzed the effects of polyphenols in black tea on breast cancer. It has been found that black tea can help overcome the spread of hormone-dependent breast tumors ().

Although black tea should not be considered an alternative cancer treatment, some studies have demonstrated the drink's potential to reduce the survival of cancer cells.

More human studies are needed to more clearly define the link between black tea and cancer cells.

Summary:

Black tea contains polyphenols, which can help fight cancer cells in the body. Although drinking this drink will not cure cancer, it may help reduce the development of cancer cells.

9. May improve concentration and mental acuity

Black tea contains caffeine and an amino acid called L-theanine, which can improve concentration and mental acuity. L-theanine increases alpha activity in the brain, which leads to relaxation and improved concentration.

Studies have shown that drinks containing L-theanine and caffeine have greatest influence on mental concentration due to the effect of this amino acid on the brain ().

This may be why many people report more stable energy levels after drinking tea, compared to other caffeinated drinks such as coffee.

Two randomized trials examined the effects of black tea on accuracy and vigilance. In both studies, black tea significantly increased participants' accuracy and alertness compared to placebo ().

It makes black tea great drink, if you want to improve your energy levels and focus without too much caffeine.

Tea composition

Black tea is a fermented product, which means that it contains many water-soluble and easily digestible components. It is based on extractive substances that give it taste, color and aroma. The younger the leaf from which the tea is made, the higher its content of extractives. This means that the infusion has the most pronounced taste and aromatic qualities.

Several dozen groups of substances have been discovered in tea, of which the largest share is occupied by:

amino acids;
alkaloids;
vitamins;
minerals;
tannins;
essential oils.

The benefits of black tea are due to the combination of these valuable components. From the group of vitamins here we can highlight ascorbic acid, rutin, vitamins B, K, A, D, E. The largest share of tannins in tea is represented by polyphenols and their derivatives, catechins and tannin. In strong black tea, the astringent effect of tannins is more pronounced.

The health benefits of tea largely depend on the caffeine or theine content in this drink. It is what invigorates, tones and prevents you from falling asleep. Tea contains more caffeine than coffee, especially green varieties. The mineral components in the composition include potassium, phosphorus, manganese, iron, zinc and iodine in small quantities.

The beneficial properties of black tea increase or decrease depending on the growing region, harvesting period, climate, fermentation time, and so on. The very first spring harvest is considered the most valuable, since young leaves contain the highest concentration of all components.

Beneficial properties of strong tea

Many studies have been and are still being conducted to identify all the beneficial and harmful effects tea on the human body. Researchers periodically make lovers of strong tea happy and sad and draw them over to the green side and vice versa. This is so controversial in terms of benefits for the body. this drink.
