What effect does improper storage have on coffee?

• A. It enhances the flavor profile of the beans
• B. It preserves the freshness of coffee
• C. It may lead to off-flavors in the coffee
• D. It increases the acidity and sweetness

Answer: (C)

Improper storage of coffee can lead to off-flavors in the coffee due to exposure to elements that compromise its quality. When coffee beans are not stored in a suitable environment—such as one that is too warm, humid, or exposed to light—chemical reactions can occur that alter the beans’ original flavor profile. For instance, moisture can lead to mold growth, while exposure to oxygen can cause the beans to become stale, resulting in rancid or undesirable tastes. This understanding emphasizes the importance of proper storage techniques to maintain the coffee's integrity and ensure the best possible flavor experience.
