What does "tipping" refer to in coffee roasting?

• A. The development of uneven flavors
• B. The charring of the bean's surface
• C. Uneven roasting due to excess heat
• D. The initial crack of the beans during roasting

Answer: (C)

Tipping in coffee roasting specifically refers to the phenomenon where the edges of coffee beans become scorched or charred during the roasting process, leading to an uneven roast. This can occur when beans are exposed to excessive heat, causing the outer layer to develop a darkened appearance while the inner parts may not be evenly cooked. This often results in a negative impact on the flavor profile, as it can lead to an imbalance where certain flavor notes become more pronounced while others are diminished or masked.

The possibility of uneven roasting due to excess heat is a crucial aspect for roasters to monitor, as it directly affects the quality and consistency of the final product. Proper heat management throughout the roasting process is essential to avoid tipping and to ensure that each batch of beans develops a balanced flavor characteristic.
