4. Grinding and Brewing

With the roasting process complete, the beans are ready to be ground and brewed. The grind size ought to match the brewing method; for example, a rough grind is right for French press brewing, while a fine grind is important for espresso. Proper grinding is essential for achieving the optimum extraction and flavor from the beans.
