What characteristic of green coffee beans should be monitored regularly?

• A. Moisture content
• B. Size of the beans
• C. Aroma profile
• D. Appearance of packaging

Answer: (A)

Monitoring the moisture content of green coffee beans is crucial because it significantly influences the quality and flavor of the coffee. Excess moisture can lead to mold growth and spoilage, while beans with low moisture content may be dried out, affecting the flavor profile during roasting. Proper moisture levels typically range between 10% and 12.5%, and maintaining this balance helps ensure optimal roasting conditions and preserves the integrity of the beans.

Other factors like bean size and aroma profile, while important, do not directly impact the immediate condition of the green coffee beans as significantly as moisture. The appearance of packaging can indicate external damage or contamination but is secondary to the internal quality metrics like moisture content, which directly influences the roasting process and final taste. Thus, consistent monitoring of moisture content is essential for maintaining quality in coffee roasting.
