What is cold brew coffee?

Cold brew coffee is made by steeping coffee grounds in cold water for an extended period, typically 12 to 24 hours. This method allows for a gentle extraction of flavors and caffeine, resulting in a smooth, less acidic cup of coffee compared to traditional brewing methods. The long steeping time at low temperatures helps to draw out the nuanced flavors of the coffee while minimizing bitter compounds that can come from hot water extraction. This process leads to a rich and naturally sweet beverage that can be enjoyed on its own or mixed with milk or flavorings.

The other options describe different brewing methods or preparations that do not align with the essential characteristics of cold brew. For instance, techniques that utilize hot water are fundamentally different and lead to varying flavor profiles. Additionally, merely serving iced coffee or adding flavorings does not encompass the unique brewing process that defines cold brew. Finally, the concept of a brewing method requiring no equipment does not accurately represent the tools necessary for preparing cold brew, even though the process itself is straightforward.
