About Onyx Cold Brew Coffee
Onyx Coffee Lab sources and roasts this coffee specifically for cold extraction. The roast uses substantial heat through caramelization and extended development to increase body and reduce perceived acidity. Onyx describes cocoa and date notes with a thick, creamy texture that drinks smoothly on its own and stands up well to dairy or plant-based milk.
The current listing does not specify origin, farm, cultivar or green-coffee process, so those details are intentionally left open. This is a purpose-built cold-brew profile rather than a general claim about all developed roasts. Time, grind, water and final dilution will determine extraction strength, clarity and finish.

Brewing Guidance
Start with a concentrate ratio of 1:5 by weight, such as 100 g coffee to 500 g cool water. Use a coarse, even grind and steep 12–16 hours, then filter thoroughly. Dilute concentrate to the preferred beverage yield. If the finish is harsh or woody, shorten the steep or grind coarser; if weak, grind finer or extend contact.
Serve and store
Refrigerate finished cold brew promptly in a clean, sealed container. For ready-to-drink brewing, start closer to 1:10 and adjust. A consistent dose and brew ratio make comparisons more useful than changing every variable at once.
Freshness, Format and Equipment
The Turin DF54 single-dose grinder offers controlled coarse grinding. Compare home coffee grinders and browse the specialty coffee collection for other roast profiles.
