What transformation is necessary before brewing coffee?

• A. Grinding coffee beans to desired consistency
• B. Steeping whole beans in water
• C. Adding flavor syrups before brewing
• D. Brewing with raw, whole beans

Answer: (A)

Grinding coffee beans to the desired consistency is essential before brewing coffee because it increases the surface area of the beans, allowing for optimal extraction of flavors. When coffee beans are ground, the essential oils and soluble compounds that contribute to the coffee’s aroma and flavor are released more readily into the brewing water. The consistency of the grind can also influence the extraction rate; a finer grind allows for quicker extraction, whereas a coarser grind results in slower extraction. Different brewing methods require specific grind sizes to ensure a balanced flavor profile. For example, espresso requires a fine grind, while a French press typically uses a coarser grind. In contrast, steeping whole beans in water, adding flavor syrups before brewing, or brewing with raw, whole beans would not effectively extract the flavors from the coffee. Whole beans cannot release their flavors adequately without grinding, while adding syrup before brewing does not affect the brewing process and raw beans cannot be brewed in a typical manner. Therefore, grinding is a necessary transformation to achieve a well-brewed cup of coffee.
