Types Of Brewing

Grind size plays a critical role in coffee brewing, affecting the extraction process and, ultimately, the flavor of the coffee. A finer grind increases the surface area of the coffee beans, allowing for quicker extraction, which is crucial for methods like espresso. Conversely, a coarser grind is suited for slower extraction methods like French press, preventing over-extraction and bitterness.

The wrong grind size can result in either under-extracted coffee, which tastes sour and weak, or over-extracted coffee, which can be overly bitter and harsh. Therefore, matching the grind size to the brewing method is essential for optimal flavor.
