Onyx Coffee Lab's Cold Brew blend is purpose-built for one thing: cold extraction excellence. Based in Rogers, Arkansas, Onyx has taken their championship-level coffee sourcing and applied it to the cold brew realm, selecting coffees that thrive in extended contact brewing. This isn't just dark-roasted coffee—it's a carefully orchestrated roast profile designed to maximize sugar browning while minimizing acidity, creating a concentrate that shines whether you're drinking it black or cutting it with dairy.
Tasting Notes
Expect rich cocoa and sweet date flavors that emerge during the long extraction process. The body is notably thick and creamy, with a viscosity that coats your palate without any harshness. Acidity is intentionally subdued—this coffee delivers sweetness and depth rather than brightness. The finish is clean and smooth, with lingering chocolate notes that make you reach for another sip. When mixed with milk or cream, those fats amplify the body and bring forward caramel undertones.
Brew Methods
This coffee is roasted exclusively for cold brewing methods. Use a coarse grind and a 1:5 to 1:8 coffee-to-water ratio depending on your preferred concentrate strength. Steep for 16-24 hours at room temperature or in the refrigerator. Strain through a fine mesh or paper filter. The resulting concentrate can be diluted with water, milk, or poured over ice. This roast profile is not recommended for hot brewing methods—the extended roast development is optimized for cold extraction chemistry.
