What exactly is
Cold brew coffee is much what it sounds like; coffee brewed cold. While cold brew may seem like a recent craze, it can be traced back to Japan as early as the 1600s, referred to as Kyoto coffee. It is thought that Dutch traders introduced this process to the Japanese, as a way of transporting large amounts of brewed coffee.
While difficult to pinpoint its exact origins, people have been cold brewing for a long time!
How is it different from conventionally brewed hot coffee?
Roasted coffee beans contain many compounds that are extracted throughout the brewing process. Some of these, including oils and fatty acids, are soluble only through high heat. Cold brew uses time, in lieu of heat, to extract the coffee’s flavors, sugars, and caffeine.
Cold brew coffee is made by steeping grounds in cold water for a period of 8-to-24 hours, then filtration for a smooth, clean finish. Cold brewing maintains the desirable flavors while leaving behind bitter oils and acids. The resulting cup is naturally slightly sweet with milder acidity compared to a traditional hot coffee, accentuating the bean’s more subtle flavors.
