First Crack

The first crack refers to the first popping sound which coffee beans make when in the process of roasting.

The reason why it cracks if that moisture trapped inside the beans expand and burst out after being heated.

After being roasted for a while, it cracks open with a snap and it’s size appears to grow.

As they continues to be heated, coffee beans will continue to release cracking sounds.

But it is this first crack that gets enough attention for it to deserve it’s own name.
