The fragrance of tea depends on the essential oils and tar substances that are contained in plants. Essential oils are complex mixture of substances that belong to the most diverse class of compounds which are soluble in organic solvents and possessing the ability to escape from water vapor. Overall the total content of essential oil is minimal; it is determined by only hundredths of a percent. For example, aromatic black tea contains about 0.02% of oil. Pure essential oil of fresh tea leaf is a green color with a strong fragrance of fresh greens. In the technological processing of tea leaf occurs the formation of a new aromatic substances that contribute to the specific flavor of the finished product. Thus, the composition of essential oil of green plants is different from the finished black tea. The substances that make up the oils can be divided into 4 main classes of compounds: acids, carbonyl compounds, alcohols and phenols. These volatile compounds found in tea are trace amounts - 0.01% of dry matter, but their role in the establishment of the tea flavor is tremendous.
Some parts of the plant contain different amounts of volatile compounds, which, in turn, differ in their compositions. The maximum concentration of essential oil found in the tender stems and leaves. The top leaf with the growing bud and two next leaves are equivalent to the content of essential oil. Further down the stem, as general coarsening occurs, oil content decreases. Which explains why the top three leaves are the most vaulable for high quality tea.
In the formation of the aroma of tea, the main role is played by aromatic aldehydes (Organic compound that has OH-group in its structure. They are used in organic synthesis as fragrances). In the composition of essential tea oils are vanilla, lavender, cinnamon aldehydes, etc. During the processing of tea leaves into black tea, the various fractions of volatile compounds undergo significant changes. The total content of these compounds increases most radically in the early stages of rolling. In the process of withering the relative content of components with higher boiling point reduces and low-boiling point, on the contrary, increases.
Along with essential oils important role in creating a tea aroma played by various resinous substances - carriers of flavor. They are in a close chemical relation with essential oils and are a complex mixture of different classes of organic compounds.
The content of tarry substances in tea leaves ranges on average from 3% to 6%. These substances are separated by several fractions, the most valuable of which is a neutral faction. It has a pleasant sweet floral aroma. In the process of technological treatment , the amount of this fraction in tea leaves increases by 40%.
During the processing of tea leaves, the content of resinous substances decreases, indicating the result of oxidation. I.e. ratio: fresh leaves – 3.48%, withered leaves – 3.27%, after two hours of curling – 2.92%, semi-finished product – 2.35%.
Through fragrance of tea, all the deficiencies that have arisen as a result of violations of technological regimens or improper storage of products, can easily be found. Disadvantages may include: acidity, mustiness, smell of the green, smoke and other uncharacteristic for tea scents. Most difficult to improve defect is acidity, which results in a violation of the fermentation process. Since in the processing of tea leaves, especially during the fermentation, occurs a reduction of Tannin. Therefore, the tea produced in violation of this process turns out with a bitter flavor and pale color of infusion. The cause of the smell of greenery is an infringement of withering, rolling, and fermentation. Such a tea has a mild flavor that the brew is a greenish color in the cup with a greenish ring on the surface and instead of the characteristic astringent taste; this product has a bitter taste. If there is excessive moisture in semi-finished product (more than 7.5%) tea is aging much faster. For extended storage. it gets the smell of dampness and can come in unsuitable conditions for consumption.
In addition, it is worth noting that different varieties of tea, as well as different ways of brewing, have an imprint on the final quality of the drink
People drink tea, to forget the hustle and bustle of the world.
Welcome to the world of unique, vibrant essence that forms an environment for communication to the world of green tea.
Apart from the fact that tea is simple to prepare and pleasant to taste, it is a unique plant which includes a huge amount of different substances that provide a favorable effect on the human body.
For some reason, only when we visit museums, we draw attention to the achievements of human race in various fields. Once inside the museum, we may explore the aircraft industry, we begin to admire the progress when standing next to the first wooden airplane, then stroll over to find a super modern fighter jet, both man-made within the last one hundred years. In museums of fine art, we are surprised to learn about the enormous changes in the technique of writing that occurred in just a few centuries, at each stage giving the world priceless masterpieces. However, once among the remarkable and infinitely fragrant teas, we rarely think about the historic characters and events, some of which dates back to antiquity.
In ancient times, people discovered wild tea trees, the leaves are plucked from the trees were just chewed or boiled in water. Century’s later people learned how to make pressed tea and then loose leaf tea. They gradually discovered many other variations throughout several millenniums, revealing all of its secret benefits. As a result, countless assortments of tea are on store shelves, readily available to all that desire this great treasure.
Despite the tremendous diversity of over 350 tea trees, each plant providing distinctive attributes within the glorious green leaves. Sky-high peaks, misty cliffs and green valleys only help these leaves to absorb a unique "spirit". The magical transformation of the collected tea leaves, from white to black, happens because of the improvements past down from ancient times.
We hope that while you are exploring our website and blog, you will assimilate many new and interesting things about the culture of tea, the types of tea brewing methods, the countless benefits of loose leaf tea and the secrets of making an exquisite cup of tea.
Considering the various properties of tea, do not forget about the main advantage of this magnificent gift of nature: the tea is able to give us joy and create a good mood. It is important to learn how to use the opportunities that tea provides to us.
Always useful to keep the favorite teas stash in the house and regularly update it.
If the tea is prepared correctly, it will reveal to us all its grace, if only treated with due care. The procedure of making tea requires greater attention, distracts from all the vain and becomes effective curative session of psychotherapy. All we need is to believe in tea.
The ritual begins when during the boiling of water, we opened the canister and breath the scent of dried tea, look at the tea leaves and think about often unknown plantation where early in the morning, unknown hands quickly and relentlessly blunt fragile shoots stretching to the rising sun. They came to us and brought freshness and flavor of mysterious place.
While filling a pot with boiling water we begin to smell the tea infusion, while pouring tea into cups we admire the bubbles that knock on the surface at the edges of the cup. So we create for ourselves our own "tea ceremony" .
