While it might be tempting to use a standard mixie, it is best to avoid it as the heat generated can compromise the flavor of the beans. If you are starting out, consider purchasing a manual burr grinder, which is highly effective and produces a consistent grind for methods like pour-over or French press. Alternatively, most coffee roasters are happy to grind your beans for you at the time of purchase based on your specific brewing method, ensuring freshness without the need for additional appliances.
