A cold brew maker is a device used to make cold brew coffee, which involves steeping coffee grounds in cold water for an extended period of time to extract flavor. The typical process for making cold brew involves adding coarsely ground coffee to a filter or infuser in the cold brew maker, then filling the container with cold water. The mixture is left to steep in the refrigerator or at room temperature for 12-24 hours, depending on the desired strength. After steeping, the grounds are filtered out, leaving a smooth and flavorful cold brew concentrate ready to be diluted and enjoyed over ice.
