A burr grinder is a type of coffee grinder that uses two revolving abrasive surfaces, or "burrs," to crush coffee beans into a consistent size. This design allows for better control over the grind size, which is important for brewing methods like espresso or French press. Burr grinders can be either flat or conical, with each type offering different grinding characteristics. Unlike blade grinders, which chop beans unevenly, burr grinders produce a uniform grind, enhancing the flavor and aroma of the coffee. They are available in manual and electric versions, catering to different preferences and budgets. Investing in a burr grinder can significantly improve your coffee brewing experience.
