Grinding coffee beans at home offers many advantages over pre-ground coffee. For starters, grinding whole beans right before brewing yields a tastier cup of coffee than pre-ground beans which lose flavor faster than whole beans. You can also adjust the grind sizes for different brewing methods such as French press or cold brew. Along with factors that affect the coffee’s taste, such as the coffee maker and type of coffee bean, the grind size can also bring out different flavor notes in the coffee.
