Cold brewed tea is tea steeped in cold or room temperature water for an extended period of time. The process brews the tea leaves slowly, using time rather than temperature to release the flavors.

Cold brewing tea is known to gently extract flavors from the tea itself, allowing for a truer tasting tea. Hot brewing can scorch the tea, destroying any natural benefits as well as creating a bitter tasting tea.

The ratio of tea to water is typically 40% tea to 60% water depending on the desired strength. Cold brewing requires a much higher quantity of tea to ensure that enough flavor is extracted into the water. The steeped tea is usually left to brew in room temperature or refrigeration for 16–24 hours.
