One of the most popular drinks in China, Dragon Well tea is part of the green teas family, having an inviting and a toasty flavor. A truly enjoyable and spectacular cup of tea.
Description of Dragon Well tea
Dragon Well tea is a type of pan-fried green tea, most commonly named Longjing tea from Hangzhou, Zheijang province in China, where is produced mainly by hand. During the production process, the Dragon Well is dried under a wood-fired Chinese pan called “wok”. This process removes the green, grassy taste and also inhibits enzyme activity. Due to the widespread opinion in China that the Dragon Well tea has a cooling effect, its popularity significantly increases especially during the spring and summer seasons.
Often called the national tea of China, Dragon Well tea is often served to head of states and foreign delegations during their visits in China. Presented as a tribute to many generations, it was given even to Richard Nixon during his memorable encounter with Mao Zedong.
This tea is very popular because of its unique properties: jade color, vegetative aroma, mellow chestnut flavor and singular shape. It has a buttery, nutty, rich texture and an enjoyable dry finish.
Commonly, Dragon Well tea is graded using a scale of six levels from superior quality to low quality so it is advisable to chose wisely when you decide to buy it. When the flavor can barely be sensed, it is clear that you deal with a poor quality.
How to store the Dragon Well tea
If the tea is sealed, keep it in a freezer. Cover with a box to insulate from temperature change. In order to get warm, leave it to room temperature before opening. This prevents condensation.
After opening the package of Dragon Well tea, it is best to keep it away from light, moisture, smell and heat in an airtight container.
Ingredients of Dragon Well tea
Like most green teas, the Dragon Well tea contains amino acids, vitamins, flavonoids, proteins, calcium, iron, fluorine, theine and has one of the highest concentrations of catechins among teas, second only to white teas.
How to brew Dragon Well tea
When it comes to brewing Dragon Well tea, the best choice is a clear glass teacup, so that you can see the beauty of the leaves as they dance and unfurl in the water. It is really spectacular. Quality of tea is related directly to the beauty of the buds. Glass is most suitable also because it disperses heat quickly and prevents over-steeping. If you see that the buds have reached the bottom, this means that the tea is ready to drink.
You should infuse a small amount of leaves in high temperature water for as long as it takes.
Pour hot water at approximately 80 - 90 degrees Celsius. Immerse until most of the tea buds has sink to the bottom of the glass and the tea liquor turns yellow. This will take 5 to 10 minutes for the first infusion. During soaking, the tea brings out a soft, pure aroma, a yellow-green color and a rich flavor.
Decant and leave a small quantity as you may use it as the seed for the next infusion.
Infuse for another 2 to 4 times with progressively shorter steeping time.
Health Benefits of Dragon Well tea
All tea comes from the same plant named Camellia sinensis. The method of production creates the different types of tea. Dragon Well tea contains the highest content of antioxidant compounds. Antioxidants are proven to fight against certain cancers, lower cholesterol levels and blood pressure, reduce the likely-hood of getting the flu and other infections, boosting the immune function of our body and help reduce the signs of aging. It is also a fat burning accelerator so let’s not forget its important benefits for diets. There’s also enough fluoride found in green tea to aid against plaque and other oral bacteria.
Side effects of Dragon Well tea
Like any other green tea, Dragon Well tea may have few side effects like restlessness, palpitations, insomnia, anxiety, irritability, increased heart rate, and elevated blood pressure due to the caffeine content. It may also cause pain in the stomach area or reduce the body’s absorption of iron by 25% so it is contraindicated to people with anemia, faintness, gastritis with hyperacidity, stomach and duodenal ulcer.
In spite of few side effects, it is worth trying it and get to know its flavor. The spectacle of drinking this type of tea is truly unique and the flavor really satisfying.... discover the spectacle of dragon well green tea
