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 too fine of a grind in a drip coffee maker, for example � will result in the brew water over-extracting the oils and aromatic compounds in the coffee, yielding a brew that is extremely pungent and bitter. Conversely, coffee that is too coarsely ground for a particular process will result in the underextraction of the oils and essences, resulting in a very thin and weak flavor. The consistency of the grind is also an important factor in the flavor of coffee. If the grounds are uniform, equal amounts of soluble compounds will be extracted from each. If the grounds vary in size, some will be over-extracted and some will be under-extracted, leading to extremely poor quality. The Model A-9® Coffee Mill uses a pair of stainless steel cutting burrs to grind coffee with precision. This helps ensure that your coffee is the best it can be.
