What started as a niche beverage in the Horn of Africa around the 15th century has graduated to a ubiquitous dining subculture. Worldwide, coffee is among the most valuable commodities, and caffeine, its vital ingredient, is the most commonly consumed psychoactive substance. More than half of American adults drink at least one cup daily. Whether a gourmet brew percolated with specialty apparatus or a generic mug-whisked instant, coffee remains a universal conclusion to dinner.

In the era of unbridled tobacco consumption, serving coffee after dinner provided a tacit signal for guests to light up cigarettes or cigars. At formal dinner parties, the practice still exists of serving coffee in separate lounges to men and women, usually accompanied by cigars or digestifs such as Cognac. Where smoking is not permitted or desired, coffee remains an appropriate method of balancing the palate after a particularly sweet dessert. In France, coffee is always served after dessert, not with it, and is savored at length before the check is requested.
Coffee aficionados argue that an after-dinner Robusta or Arabica brew is not so much indulgence as plain healthy living. Coffee is one of the single leading sources of antioxidants in the Western diet, absorbed more effortlessly into the bloodstream than other nutrients. Likewise, coffee increases the metabolic rate by up to 11 percent, improving fat burning after a heavy meal. Evidence also exists that coffee boosts cognitive brain function, including alertness, by facilitating the enhanced firing of neurotransmitters. After a long, sumptuous dinner, a quick shot of coffee is the ideal way to counter sluggishness and lethargy.
Many diners shy away from the after-dinner coffee in the belief that even the shortest dose is responsible for indigestion, stomach pains or even heart palpitations. The real culprit of these symptoms is often overindulgence of foods that were too spicy or rich. Medical evidence shows that drinking an espresso after dinner slows digestion, better equipping the body to break down a heavy meal. In particular, caffeine slows the transfer of food from the stomach to the duodenum and increases metabolism. Contrary to popular belief, coffee does not cause stomach ulcers, although it can exacerbate heartburn in some people.
Italian or French restaurants typically serve a short shot of espresso in a demitasse cup as their after-dinner coffee, delivering the perfect amount of rich roast flavor to complement a heavy dinner. While it is acceptable to add a dash of milk or cream (called a macchiato), it would be something of a faux pas to order a cappuccino after dinner. This frothy, foaming milk and coffee blend dusted with chocolate powder is strictly a morning drink; purists would never drink it after midday, because the milk is thought to hamper digestion. Italians do not drink it after any meal, even lunch.
