Coffee at First Crack - Half a Bean Version
Short video showing the acrobatic coffee beans as they enter the first crack phase of coffee roasting. These were roasted on an oven tray so I could capture the transformations of coffee without all the motion of a normal rooster. You can see the coffee expand a bit just before the it does its move. Check out the spin at the end!
First crack occurs when the bound up moisture in the bean reaches the temperature where water turns to steam (water vapor), and suddenly escapes the coffee. This force can visibly enlarge/puff up the coffee, as well as make it move as you see here! - Thompson
