Cold Brew is a coffee beverage made by steeping coarsely ground coffee beans in cold or room-temperature water for an extended period, typically 12 to 24 hours. This slow extraction process results in a smooth, rich concentrate that is often diluted with water, milk, or served over ice. While its origins trace back centuries, possibly to 17th-century Europe or Japan, it has become a modern café staple worldwide.
A standard serving of cold brew coffee (without added sugar or cream) is virtually fat-free and contains minimal carbs and protein, with a calorie count typically under 5 calories per cup. Its key nutrients include antioxidants like chlorogenic acids and a moderate amount of caffeine, which can vary based on the bean type and dilution ratio.
Cold brew is unique because its slow, cold extraction method reduces the perceived acidity and bitterness of coffee, making it smoother and naturally sweeter than hot-brewed counterparts. Nutritionally, this method may preserve certain delicate antioxidants that can be degraded by high heat, though research is ongoing.
