Wake-up call: lighter roasts mean complex flavor. SToK Bright & Mellow Cold Brew Coffee is a unique light roast cold brew that’s refreshing. Think vibrant. Bright. Full of character. Mellow? Yes. Boring? Never. The Bright & Mellow Arabica beans mellow out and open up, so you get a vivid cold brew coffee, served black and unsweetened. At SToK, we brew our cold brew for at least 10 hours for a bold, one-of-a-kind flavor that’s never bitter. Every batch of 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 bottled coffee. Wake up your passions with a SToK cold coffee drink you can enjoy throughout the day. 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.
