A coffee cup is not just a vessel for holding coffee—its material, size, color, and even the shape of the rim all influence how a cup of coffee expresses its aroma and temperature. Ceramic cups and porcelain cups convey distinctly different attitudes toward coffee, while bone china cups allow coffee to cool more slowly and preserve its flavors more completely; different capacities correspond to drinking styles such as black, with milk, or au lait; and a white interior makes it easier to observe the coffee's color. Coffee cups and black tea cups also differ in rim width, wall thickness, and translucency. In addition, the direction in which the cup is placed, the steps for warming it, and the way it is cleaned are all details that cannot be overlooked if you want to preserve coffee's rich aroma.
