To extract the full flavour of the coffee, it's best to brew using a fresh grind coffee of not more than 3-5 minutes. This is even more true for the espresso type of brew that requires fine grind, uniform size and high precision. A high-quality stainless steel burr grinder is a must to achieve this. This 39 grind settings digital stainless steel conical burr grinder provides levels from highly coarse to espresso to Turkish fine. Comes with a built-in timer that can produce 1 to 10 cups in seconds.
