    By Rodolfo Zanin for Perfect Daily Grind

    “Many coffee professionals choose to become Q graders for a number of reasons. Whether it's to know more about sourcing green coffee or achieving more defined roast profiles, the Q grader certification programme can be a useful - or even necessary - tool to progress in your specialty coffee career. In light of this, certifying as a Q grader has become something of an industry standard. But like many other certifications across the coffee supply chain - ranging from carbon neutral to organic - maintaining a Q grader license requires regular recertification.
