How Long Should 1st Crack Last?

Episode 93: What’s really happening during first crack—and how much control do you actually have over it? In this episode, Stephen and Catherine tackle a listener question from a new home roaster dialing in their early batches on an SR540. The conversation dives deep into one of the most critical (and confusing) phases of roasting: first crack. Why does it sometimes drag on? Can you “compress” it? And how does it impact overall development and flavor? They break down what’s normal, what’s not, and how to think about airflow, heat application, and roast progression—especially if you’re aiming for lighter profiles like African coffees. Then, the episode shifts to a relatable struggle: waiting for coffee to degas. Is it really necessary to wait days before brewing? What actually happens if you grind early—or let grounds sit? And does brewing method (like cold brew) change the rules? This episode is packed with practical guidance for new and intermediate home roasters looking to better understand roast phases, improve consistency, and get the most out of every batch. In this episode: Whether you can (or should) compress first crack How airflow and heat affect roast development Tips for roasting lighter coffees without stalling progress If you’re trying to level up your roasting—or just impatient to drink your coffee sooner—this one’s for you!
