Unlike hot brewing that releases bitter acidic compounds, cold brewing produces a smoother result that is 67% less acidic. This gentle technique highlights the specific flavor profile and undertones of the coffee grounds and produces a bolder taste. This Digital Accelerated Cold Brew Coffee Maker by Gourmia circulates coffee over the ice basket so you can enjoy your coffee icy cold and undiluted — quick. Instead of the typical 24-hour cold brew period, this coffee maker gives you quality coffee in as little as 4 minutes. Make the sweetest, smoothest, and the chillest brews in literally just a manner of minutes!
