Pure water is essential for making the perfect cup.
With a few exceptions, city water generally just doesn't cut it. Bottled mineral water or water from a reverse osmosis unit is better. Since water boils at 212 degree's F, it's important to cool it off just a bit. Then, by adding 2 ounces of cool water, you will get very close to the 165 degree mark. With the exception of the powdered tea, most of our teas are brewed at 1 teaspoon per 10 ounces of water.
