• C. An undesirable taste caused by poor processing or roasting mistakes
• D. A flavor that indicates high-quality coffee

Answer: (C)

An "off-flavor" in coffee refers to an undesirable taste that arises from poor processing or roasting mistakes. When coffee beans are not processed or roasted correctly, they can develop flavors that are unpleasant to the palate. These off-flavors can stem from a variety of sources, such as over-roasting, under-roasting, or contamination during processing. These undesirable tastes detract from the overall quality and enjoyment of the coffee.

Understanding off-flavors is crucial for coffee professionals as they indicate issues in the coffee's journey from farm to cup. It helps roasters and brewers to identify problems and make necessary adjustments to enhance the taste and quality of the coffee served to consumers. Proper techniques in sourcing, processing, and roasting are essential to minimizing these off-flavors and achieving the desired flavor profile in the final brew.
