The “Crack” Stages in Roasting

Coffee roasters often identify roast levels by the sounds beans make during roasting:

First Crack

Beans pop like popcorn.

• Marks the beginning of light roast

• Beans expand and become drinkable

Second Crack

A softer, faster cracking sound.

• Indicates dark roast territory

• Oils begin moving to the surface

Simple Tip for Customers

If the beans look:

• Dry and light brown → likely a light roast

• Medium brown with balanced color → medium roast

• Dark and shiny with oil → dark roast

Why Roast Level Matters

Roast level affects:

• Taste

• Aroma

• Acidity

• Body

• Brewing style

Lighter roasts highlight where the coffee comes from, while darker roasts highlight the roasting process itself.
