What is Cold Brew Coffee?
Cold brew coffee is a popular beverage that is made by steeping coarsely ground coffee beans in cold water for an extended period of time, resulting in a smooth and less acidic flavor profile.
Unlike traditional hot brewing methods, which involve exposing coffee grounds to hot water for a short duration, cold brew involves a slow extraction process that occurs over several hours or even overnight.
This extended steeping time allows for the gradual release of coffee’s flavors, resulting in a more mellow and less bitter taste. The coarsely ground coffee beans used in cold brew also contribute to the beverage’s smoothness, as they produce less sediment and fewer bitter compounds compared to finely ground coffee.
Additionally, the cold water used in the brewing process helps to reduce the extraction of certain compounds that can contribute to acidity in coffee. As a result, cold brew coffee is often described as having a lower acidity level, making it a favorable choice for individuals with sensitive stomachs or acid reflux issues.
