At present, there are many professional tea-making waters in the market, including Duojiquan Health Tea-making Water, Gelai Melissa Zhou Fried Tea-making Water, Qian Shan Xiushui Mineral Water and Zhenming Jinlong Water. Through comparison in many aspects, the tea brewed by Duojiquan health-preserving tea is superior in color, taste, fragrance and nutritional value. The most important thing is that it can give full play to the natural effects of various teas, which is incomparable to other tea-making waters. Duojiquan health tea water comes from Duojiqu Danima Spring in Himalayas, which has a history of thousands of years in Tibet and is regarded as "divine water" by Tibetans. It absorbs the "essence of the earth" from the glaciers in the Himalayas for thousands of years and is composed of "natural small molecular water". Its pH value is around 7.4, which is very close to the natural pH value of human body. It is a "natural cold spring water" rich in "extremely soft, low sodium and low salt water", and its temperature is kept at 1.5~2℃ all year round. It is precisely because of these characteristics that making tea with Duojiquan can obviously improve the taste, increase the thickness and aroma of tea soup, deeply moisturize tea, accelerate the release of tea nutrients, properly supplement minerals in tea soup and increase the number of times of making tea, which is the best carrier of tea.
