Many people around the world, including chefs and even scientists believe that white tea has numerous benefits towards everyone’s health. But do you really know what exactly white tea is and how you could benefit from white tea leaves? The immature tea leaves are alternatively called white tea. These loose leaves are picked from the tea plant just before the plant has fully bloomed. The name ‘white tea’ came from the fine silvery fuzz covering the tea leaf and making it white in color. The four distinct varieties of white tea include the White Peony, Silver Needle, Long Life Eyebrow and Tribute Eyebrow. The difference between them is the proportion in which the tea leaves are blended with the tea buds.
Harvesting White Tea
Usually buds turn into tea in two days after they are picked. When two tea leaves are mixed with one tea bud, it forms the White Peony and if the mixture is made completely of buds, it is termed as the Silver Needle tea. The low quality tea variety called Long Life Eyebrow is made by mixing up the left over leaves after the White Peony and Silver Needle harvest. Tribute Eyebrow is processed using a special tea bush and is also a lesser quality tea. All four white teas can be purchased in loose leaf forms. On the other hand, teas available in bags have comparatively less quality and flavor than white tea. Tea bags are generally tea leaf dusts that remains at the bottom of tea bins after harvesting, reducing the desired quality and flavor.
White Tea Research
Scientific research has also shown that white tea provides additional protection against skin cancer, colon cancer, stomach cancer and even prostate cancer. Studies on the effect of white tea extract on skin exposed to direct sunlight has shown improved protection and reduced cell damage. A partially repaired immune system was also observed in some test subjects that consumed white tea leaves. Scientists found a wealth of antioxidants present in white tea and they suggested it may have anti-aging effect. Some compelling evidence has also been found in the direction of disease prevention using white tea leaves. It is shown that the white tea leaf extract may have the ability to stop pneumonia and the bacteria that causes Staph infection. It is also used to prevent tooth decay, gum disease, plaque and even bad breath.
What Else Can White Tea Do for You?
It is also believed that white tea leaf has anti-fungal effects. Recent studies have shown that some fungal types became inactive when the fungal drugs are consumed along with white tea leaves. Results of this study also show that white tea leaves might be used to prevent the fungus growth in certain similar conditions. Cholesterol is a health requirement and there are two kinds of cholesterol: good cholesterol and bad cholesterol. It is the bad cholesterol that causes the hardening of the arteries that could lead to heart attack. A type of antioxidants called catechins has been found to reduce bad cholesterol; white tea also helps raise the good cholesterol in the human body. It has been suggested that white tea leaves could lower the blood sugar levels, and thus reduce the occurrence of diabetic symptoms. More scientific research and results can be expected in the near future as the research on white tea continues.
Due to the variety of minerals, vitamins and other elements contained in tea, this drink improves health, relieves fatigue, strengthens the immune system and has an overall tonic effect on the body.
Mineral substances contain in green tea leaf and in finished products, it constitutes about 5-6% of dry matter. Among them are the following: potassium, phosphorus, calcium, magnesium, sulfur, iron, manganese, fluoride and others. With the aging of the plant total number of minerals increases, while the most valuable part of the soluble reduces. Only the components of relatively small molecular weights which are infused with hot water give a specific accent to the tea infusion. Between the quality of tea and the content therein of soluble mineral substances there is a direct link.
The potassium content in the tea leaf is 50-60% of all mineral substances and depends on the mineral nutrition of plants. This compound plays a very important role in the livelihood of tea tree; it is given a great importance in the synthesis of carbohydrates and proteins, and in the general metabolism. Potassium is very important to the human body; it prevents muscle cramps and regulates fluid and electrolyte balance.
Another important mineral is located in the tea - phosphorus. Its content ranges from 15-20% of weight of all mineral substances in tea. The properties of the finished product depend on its quantity. The two top leaves and a bud have higher content of phosphorus compare to the lower coarse tea leaves and stems. It is known fact that phosphorus is needed for the human body for normal functioning, as part of the nervous, brain tissue and bones.
Despite the slight content, copper and iron play an important role in plant’s life. They are part of some physiologically important organic compounds, such as enzymes. Another, small in content, but necessary for redox processes, is manganese. Its share is approximately 1-4%. Due to the iron content, tea has a beneficial effect on the human blood, as well as a good means for the prevention of various vascular diseases. In addition, the body needs iron to transport oxygen.
The complex experiments revealed effects of the duration of brewing tea and the quantity of the tea leaves on the degree of content in the drinks of various trace elements. Adding citric acid increased the yield of all elements, except copper. In the end, it was found that a tea drink satisfies the daily requirement of zinc, copper and manganese at 1, 2 and 50% respectively.
Now let us turn to vitamins contained in tea. This is mainly vitamins B complex and C. The tea shoot has the following B complex vitamins: B1 (thiamin), B2 (riboflavin), B3, and B5 (PP), B6, B12 and P. Since these compounds are very stable, in the processing they are almost completely transformed into finished products. Content of vitamin B1 is small - an average of 0.3 - 10 mg per 1 kg of dry tea leaves. In the body this vitamin (B1) regulates metabolism of carbohydrates, amino acids, fatty acids, has versatile affect on the function of the cardiovascular, endocrine and central nervous system. Vitamin B2 has positive effect on the skin and mucous membranes, the health of the liver. The most important is the presence in tea of vitamin P. One of its most important properties is the strengthening of the capillaries of the plant. During the technological processing of raw material quality and quantity of the vitamin are undergoing significant changes. Its content is reduced from 20-25% in green tea to 8-15% in the final. Along with others, the tea contains vitamin PP that is important for normalizing the higher nervous activity, the functions of the digestive system. It also affects the cardiovascular system, in particular, expanding the small vessels.
Tea leaves are rich in Vitamin C. Gentle leaves contain approximately 2-3 times more of this vitamin than the coarse. In the process of refining its amount is sharply reduced, especially during the fermentation and drying. This vitamin is essential for strengthening the immunity of a person, it reduces the risk of infections, but also useful for the prevention of osteoporosis and periodontitis (inflammation of the periodontal tissue, i.e. tissue surrounding the tooth root). Tea fluoride also provides the beneficial effect on teeth. This element exists in tea leaf as anion. Fluoride anion produces various fluoride compounds and covers the surface of teeth to prevent bacterial attack. Just wanted to point out that tea is very useful for vision, because it contained β-carotene and other elements, strengthens blood vessels.
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
According to “urban legend”, iced tea was discovered accidentally by an enterprising Englishman Richard Blechynden who had come all the way from Calcutta, India to represent teas from the Far East at the 1904 St. Louis World’s Fair. Not meeting with much success in the stifling heat, Mr. Blechynden poured the tea over ice and met with a near instant success. However, the oldest printed recipes for iced tea were published in 1870. Russian tea with sugar and lemon slices was fashionable in the USA and served in hotels in 1860th under the name “tea a la Russe” both hot and cold.
America is unique in its tea consumption habits. In the United States over 85% of the tea is consumed as an iced beverage. Iced tea has gained wide spread popularity as an alternative to carbonated soft drinks being an attribute of a healthy life style. This refreshing drink is traditionally served sweetened or unsweetened with lemon slice over ice cubes in a tall glass. Black tea is the classic ingredient used to make iced tea. With incredible offers on the market today for black and green teas, Rooibos, blended teas, ayurvedic, flavored, herbal and fruit teas, try to find your preferred beverage by experimenting with such a variety. For iced tea to have consistent strengths from start to finish, use ice cubes made from leftover tea.
Here are three ways for making perfect iced tea:
Hot Water Method
Boil water. Steep your favorite tea with double the amount of loose leaf. Strain prepared drink to remove the tea leaves. Sweeten with sugar or honey if desired. Pour the strained tea into a pitcher with ice cubes. Serve in a tall glasses filed with additional ice cubes, garnish with a lemon slice and a spring of fresh mint.
Cold Water Method
This method is the best to achieve a crystal clear drink result. Fill a large pitcher with cold water and loose leaf tea (8 teaspoons of tea per 4 cups of water), let it chill overnight. Strain the mixture to remove tea leaves. Sweeten with sugar syrup if desired. Serve and enjoy.
Sugar syrup: combine equal amounts of water and sugar in a small saucepan. Bring to boil and simmer until clear, about 7 minutes. Cool and store in refrigerator. You may add lemon zest to the mixture while boiling, proceed as directed, discard the zest and enjoy lemon sugar syrup with your favorite iced tea!
“Sun tea” is tea brewed by being left to steep in the sunlight. In a glass jar, combine water and loose leaf tea (8 teaspoons of tea per 4 cups of water). Place the jar in a warm, sunny location for 3-4 hours. Strain the mixture to remove tea leaves. Sweeten with sugar syrup if desired. Chill in refrigerator. Serve and enjoy!
There are also lots of different variations of iced tea. Common modifications to the traditional recipe include adding fresh fruit, flavored syrups, cranberry or orange juice, sparkling water and even champagne to make a delicious tea drink. Bubble tea is very popular in Taiwan and worth to try on a hot summer day as an exotic desert. A strong black tea sweetened with condensed milk and served cold with large tapioca pearls. Great low calorie desert that quenches your thirst! The possibilities for making a unique and refreshing glass of iced tea are virtually countless. Experiment and enjoy your summer!
Chinese Wū long or Oolong is a type of tea located between green and black in the Chinese classification. In other words, Oolong is half-fermented tea. Oxidation ranges from 20% to 40%, and the most characteristic feature of this tea is that the leaves are fermented unevenly. Along the edges of the tea leaf fermentation can be quite astringent, almost like black tea with well pronounced reddish rim around a leaf but in the center of leaf fermentation, is very weak, close to green teas. As a result, Oolongs have a wonderful aroma and taste that combines the freshness of green tea and tartness of black tea.
Oolong combines the best qualities of both green and black teas. Some highly fermented Oolongs give a fairly dark brown-reddish infusion. However, such Oolongs constitute only a small share of the vast diversity of this type of tea. Basic and famous Oolongs have a gentle light yellowish or greenish tinge honey extract. By appearance of the infusion, they are closer to green teas and by taste - to black teas. A good Oolong is both refreshing and delicious with no trace of bitterness and stronger aroma than any green or black teas. Oolong is a well known type of Chinese tea used in ceremonies. A widely-used ceremonial method of brewing Oolongs in Taiwan and China is called Gongfu Cha. For a complete appreciation of the taste of this tea, tea pairing is recommended: tea bowl and snifter cup used to appreciate the tea's aroma. Tea poured into a snifter cup and a drinking bowl is placed upside down over the top of the snifter cup. Then the two are inverted so that the snifter cup is upside down in the drinking bowl. The final stage is when the snifter cup is lifted and the tea is released into the drinking bowl. After all this manipulations, tea drinkers can respectfully receive the aroma and then enjoy the taste.
There are two main types of Oolong that are grown and harvested in China and Taiwan, the mainland and island tea. The next classification is the type of traditional treatment and characteristics of climate and soil. Oolongs grow high in the mountains, shrouded in fog, on the poor stony soils. The quality of tea depends on the orientation of the slope, the number of fogs during the growth and professionalism of collectors, who manually collect and sort out the tea leaves in difficult mountain conditions.
Oolong often resembles the form of twisted lumps consisting of strongly folded and compressed whole leaves. When touched, the lumps are elastic and dense. Fresh tea should be slightly shiny and have a strong fragrant. During the brewing process, the tea leaves unfold, expend and consume the entire volume of the teapot when steeped 2-3 times. Usually, Oolong brewed with water temperature of 176-194º F for 3-4 minutes. A teapot 150 ml takes about one heaped teaspoon. Expensive Oolongs can withstand multiple infusions up to 20-25 times. The fragrance of tea can vary from delicate peach tones to astringent walnut, with a corresponding color change of infusions darker with each subsequent brewing. There are varieties of oolong that color does not change and remains yellow-green, while others, originally given infusions of intense color give a pale infusion each subsequent brewing.
Oolong tea is the most diverse among Chinese teas in terms of taste and appearance . Oolong is tea-perfection conceived by Heaven and Earth.
