Onyx Coffee Lab | Guatemala | COLD BREW


This coffee is intentionally sourced and roasted to craft the perfect cold brew coffee. Lower in acidity and high in sugar browning, this coffee reacts well with fats in dairy or tastes smooth and sweet on its own. We look for coffees that will take a large amount of heat during the caramelization process and extend the roast times to increase the body and remove acidity. Designed for cold extraction only, expect notes of Cocoa, Dates and a thicken creamy texture.

This method uses time instead of heat to extract the coffees, which results in a wholly different taste profile over traditional filter brews using hot water and dilution. We utilize cold brewed coffee in our cafes as an ingredient, and we also infuze it with some nitrogen to amplify the creamy texture of our cold brew. The name of the game of cold brewed coffee is versatility and drinkability, making it perfect as a ready to drink option that you can pull out of your fridge, or as a base for a milk beverage. We also hear it can make a pretty great milkshake…

Our approach to creating blends is a bit different at Onyx. Instead of choosing coffees from specific countries or regions that will, in theory, intertwine well to create complex & cohesive flavors like most, we start from the end and work our way back. This perspective means we
