How do rapid cold brew makers work?
A common version of the instant cold brew coffee maker operates with a simple recirculation pump, like this model from vinci we tested.

Either way, the minerals in both go to work to pull more flavor from the grinds during the brewing process.Cold brewing is an incredibly versatile technique that brings out a smooth, mellow and delicately sweet taste in coffee. To brew, fresh grounds are fully immersed in cool or room-temperature water and left undisturbed for hours. Without heat, less acid is extracted from the coffee, creating a smooth cup.Research suggests that hot brew coffee has higher antioxidant content than cold brew. The hot water in the brewing process helps the coffee beans release health-promoting compounds — such as antioxidants — into the drink.Cold brew coffee can definitely go bad if it’s not refrigerated. Coffee goes bad when it’s left out because it’s exposed to oxygen, which hastens the process of oxidation. This process impacts the way your coffee tastes and smells. Air, moisture, heat and light can all contribute to the process of oxidation.

In terms of caffeine content, cold brew coffee can be stronger because it is brewed with a higher coffee-to-water ratio and a longer steeping time.The cold water slows down the extraction of the tasty parts of coffee. AND it actually changes what is extracted and what is left in the ground coffee. Compared to hot brewed coffee, a cup of cold brew can be 60% less acidic and bitter. That happens because the acids that turn to bitter don’t get extracted.Cold-brewed coffee: Is easier on your stomach.
