What is Espresso
Espresso is generally thicker than coffee brewed by other methods, with a viscosity similar to that of warm honey. This is due to the higher concentration of suspended and dissolved solids, and the crema on top (a foam with a creamy consistency). As a result of the pressurized brewing process, the flavors and chemicals in a typical cup of espresso are very concentrated. Espresso contains more caffeine per unit volume than most coffee beverages, but as its usual serving size of 25-30 ml (1 US oz) is much smaller than other coffee drinks, the overall caffeine content of a single serving of espresso is generally lower than that of other coffees. While the exact caffeine content of any coffee drink will vary, a typical 30 millilitres (1 US fluid ounce) serving of espresso contains approximately 65 milligrams of caffeine, but a typical 240 millilitres (8 US fluid ounces) serving of drip coffee contains between 150 and 200 mg of caffeine. The three dispersed phases in espresso are what make this beverage unique. The first dispersed phase is an emulsion of oil droplets. The second phase is suspended solids, while the third is the layer of gas bubbles or foam. The dispersion of very small oil droplets is perceived in the mouth as creamy. This characteristic of espresso contributes to what is known as the body of the beverage. These oil droplets preserve some of the aromatic compounds that are lost to the air in other coffee forms, enhancing the strong flavor of espresso. The "crema" is a layer of dense foam that forms on top of the drink. It consists of emulsified oils in the ground coffee turned into a colloid, which does not occur in other brewing methods. Crema is produced when water, placed under very high pressure, dissolves more carbon dioxide, a gas present inside the coffee that is produced during the roasting process. Espresso is served on its own, and is also used as the base for various other coffee drinks, including caffe latte, cappuccino, caffe macchiato, caffe mocha, flat white, and caffe americano.
