How the Grind affects flavor
The flavor of coffee depends on a variety of factors, including the quality, freshness, and roast of the beans, the purity of the brew water, the cleanliness of the brewing equipment, and the brewing temperature. The fineness and consistency of the grind is also critical.
Coffee that is ground too fine for a particular brewing process – using a fine espresso grind in a drip coffee maker, for example – will result in the brew water
The consistency of the grind is also an important factor in the flavor of coffee – and absolutely critical when making great espresso. If the grounds are uniform, equal amounts of soluble compounds will be extracted from each. If the grounds vary
in size, some will be
Coffee grind quality is directly related to the type of grinder used. High speed grinders with small burr sets are usually not able to produce the fineness or consistency required for the best espresso. They also excessively heat the beans while grinding, resulting in lost flavor and aroma.
The KitchenAid® PRO LINE™ Burr Coffee Mill uses a pair of large, commercial- style, flat cutting burrs to grind coffee with precision. Frictional heating is minimized with a gear reduction system that slows burr rotation, and uniformity is enhanced with a helical- gear that transports beans to the burrs at a controlled rate. The result is a superb grind that makes your coffee and espresso the best it can be.
