Cold brewing is a method of making coffee that involves steeping coarsely ground coffee beans in cold or room temperature water for an extended period, typically 12 to 24 hours. This process extracts flavors and caffeine without the bitterness often associated with hot brewing methods. The result is a smooth, less acidic coffee concentrate that can be enjoyed on its own or diluted with water or milk. To prepare cold brew, you start by mixing coffee grounds with water in a jar or pitcher. After steeping, the mixture is filtered to remove the grounds, leaving behind a rich coffee concentrate. This concentrate can be stored in the refrigerator and served over ice, making it a refreshing beverage, especially during warmer months.
