Brewed low and slow, SToK Un-Sweet Black Cold Brew Coffee is Bold & Smooth. For those who like their cold brew black and their dreams in color. No cream. No sugar. You get a medium roast cold brew blend served black and unsweetened. At SToK, we brew our cold brew coffee blend for at least 10 hours for a bold, one-of-a-kind flavor that’s never bitter. Every batch of SToK Cold Brew Coffee uses a higher ratio of Rainforest Alliance Certified, Arabica-based coffee beans to water than hot brewed coffee, yielding a smooth and flavorful coffee. Looking for the best brew to suit the mood? Check out all the SToK flavors for the perfect fit, with Bright & Mellow as our lightest roast and Espresso Blend as our darkest.
