Mizudashi describes both a method of infusion akin to a cold-brew, and also a blend of tea that has been optimized for the method. Infusing at a low temperature brings forth the Umami flavor in of tea, and the longer steeping time makes for a beverage that saves on the amount of tea leaves required for a satisfying brew. Mizudashi is the Japanese equivalent of an iced tea, it is sure to refresh. (For specific instructions on how best to prepare Mizudashi, click here.)
