Behind a little known temple in the back of the mountain is a running stream from the same source as the Tiger Run Spring, the famous sweet tasting water that not only nourishes the tea plants, but brews an unparalleled cup of Dragonwell. This secret water source is where all the tea masters like Mr. Dai go to get water to brew their own tea. Free from tourists, he said. So I can not disclose its coordinates either- but I did fill a bottle to bring back to analyze what the mineral content is. Hopefully soon, we can all use the right water for each tea!
