Now the roast is a little over 10 minutes long. You can see a definite darker tan now. First crack is happening, which is when the beans reach a certain internal temperature causing the moisture/air inside the beans to break open the bean, creating a popcorn popping type sound. You can’t hear it here due to the hood fan. First crack tends to happen rapidly in many roasting methods, like an air popcorn popper which I use occasionally, and my Behmor drum roaster which is now my standard method. But for stovetop roasting, first crack happens much more slowly, and here stretches between 10 and 15 minutes.
