TECTONIC ROASTING LAB 🔥 Beyond Roast Color: Understanding Development, Rate of Rise & Roast Character Join us for an immersive look into the science of coffee roasting at the Tectonic Coffee Roastery & Quality Control Lab, hosted by Danny Castrellon, Head of Operations and Roasting. Drawing on more than six years of professional roasting experience, Danny will guide participants through one of the most misunderstood aspects of coffee roasting: how roast development and Rate of Rise (ROR) shape flavor beyond what color alone can reveal. Many assume roast color tells the whole story—but two coffees with nearly identical color readings can produce remarkably different cups. Through discussion, real roast data, and guided tasting, we’ll explore how roast trajectory influences sweetness, acidity, body, flavor clarity, and perceived roast character. Whether you’re a home roaster, barista, coffee professional, or simply curious about what happens inside the roaster, this lab offers a behind-the-scenes look at the decisions that define exceptional coffee. What You’ll Learn • What roast development really means • How Rate of Rise (ROR) influences flavor development • Why similar color readings can produce dramatically different cups • How roast profiles affect sweetness, acidity, body, and origin expression • Why coffees can taste “roasty” without appearing dark Experience Includes • Guided presentation on roast development and ROR • Real-world roast profile comparisons • Sensory evaluation of coffees roasted with different roast trajectories • Q&A inside Tectonic’s working roastery and Quality Control Lab 📍 Location Tectonic Coffee Roastery & Quality Control Lab 3821 S.
