How to Make Cold Brew Iced Coffee

In a large, nonreactive vessel, combine ground coffee and water, stirring to fully saturate all the coffee grounds. Cover and let stand at room temperature for at least 8 and up to 12 hours. Strain the cold brew concentrate through a fine-mesh strainer lined with cheesecloth or a large coffee filter or other filtering medium to remove grounds and sediment. Transfer cold brew concentrate to an airtight container and refrigerate until thoroughly chilled. To serve, pour the chilled cold brew concentrate over ice and dilute to taste with cold water, milk, or a milk substitute.
