White teas are best when prepared like green tea. Their delicate nature will be destroyed by water that is too hard or too hot. Filtered water or spring water that is not too heavy will produce the best cup. Water that is too hot will cook the delicate leaves and render an inferior-tasting, astringent cup. The ideal water temperature is between 175 and 180 degrees Fahrenheit; you can easily obtain this temperature by bringing water to a boil, then removing it from its heat source and letting it sit for about 1 minute. Add 1 rounded tablespoon of tea per 6 ounces of water in a cup or teapot. Pour water over the tea and steep for 2 minutes and 20 seconds. Future brewings, adjust to taste.
