What is cold brew coffee?

Cold brew coffee is made by soaking coarsely ground coffee beans in cold or room-temperature water for an extended period, typically 12 to 24 hours, allowing the water to slowly extract flavor, oils, and caffeine without heat. The result is a concentrate that can be diluted with water, milk, or ice, or served as-is depending on the brew strength.

This method differs fundamentally from iced coffee, which involves brewing coffee hot using standard methods and then chilling it over ice. The cold steeping process produces a naturally sweeter, smoother cup with lower acidity because heat is not involved in extraction. Many drinkers find cold brew easier on the stomach and appreciate its mellower flavor, which highlights the coffee's origin characteristics rather than emphasizing bitterness.

In Ipoh's cafe scene, cold brew appeals to those seeking a refreshing alternative to hot coffee without the sharp edges typical of chilled hot-brewed versions. Cafes often prepare cold brew in batches, keeping concentrate on hand for quick service. The drink works well both straight and as a base for milk-forward drinks like cold brew lattes or flavor additions. Specialty coffee providers in the area frequently feature cold brew as a signature offering, particularly during warmer months.
