What exactly is
Cold brew coffee is what it sounds like; coffee brewed cold. While cold brew seems like a recent craze, it is traced 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 brewing extracts. Hot water dissolves oils and fatty acids. Cold brew uses time, in lieu of heat, to extract the coffee’s flavors, sugars, and caffeine. So cold brew is less acidic, more naturally sweet, and peppy.
