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 essential for brewing methods like espresso or French press. Burr grinders can be either flat or conical, with each type offering different benefits in terms of grind uniformity and heat generation. Unlike blade grinders, which chop beans unevenly, burr grinders produce a more uniform grind, enhancing the flavor extraction during brewing. They are available in manual and electric versions, catering to different preferences and budgets. Investing in a burr grinder can significantly improve the quality of your coffee.
