How does grind size generally affect coffee extraction?

• A. Finer grinds decrease extraction speed
• B. Coarser grinds increase extraction speed
• C. Finer grinds increase extraction speed
• D. Grind size does not affect extraction

Answer: (C)

Grind size plays a crucial role in coffee extraction, particularly in how quickly and efficiently flavors and compounds from the coffee grounds are drawn out during the brewing process. Finer grinds have a larger surface area compared to coarser grinds, which allows for more rapid interaction with hot water. This increased surface area facilitates a quicker extraction of soluble compounds, resulting in a more intense flavor profile in a shorter amount of time. In contrast, coarser grinds, due to their reduced surface area, slow down the extraction process. This results in a longer brew time needed to achieve the desired flavors and may lead to under-extraction if the brewing method is not adjusted accordingly. Thus, the relationship between grind size and extraction rate is essential for achieving the desired flavor in brewed coffee, making the understanding of grind size a fundamental aspect of coffee preparation.
