Coffee Beverages

Coffee can be presented in a variety of ways. Drip-brewed, percolated, or French-pressed coffee may be served with a dairy product such as milk or cream, or dairy substitute, or not. It may be sweetened with sugar or artificial sweetener. When served cold, it is called iced coffee.

Espresso-based coffee has a wide variety of possible presentations. In its most basic form, it is served alone as a shot or in the more watered-down style café américano: a shot or two of espresso with hot water added. Reversing the process by adding espresso to hot water preserves the crema, and is known as a long black. Milk can be added in various forms to espresso: steamed milk makes a caffè latte, equal parts steamed milk and milk froth make a cappuccino, and a dollop of hot foamed milk on top creates a caffè macchiato. The use of steamed milk to form patterns such as hearts or maple leaves is referred to as latte art.

A number of products are sold for the convenience of consumers who do not want to prepare their own coffee. Instant coffee is dried into soluble powder or freeze-dried into granules that can be quickly dissolved in hot water. Originally invented in 1907, it rapidly gained in popularity in many countries in the post-war period, with Nescafé the most popular product. Many consumers determined that the convenience in preparing a cup of instant coffee more than made up for a perceived inferior taste. Paralleling the rapid rise of instant coffee was the coffee vending machine, invented in 1947 and multiplying rapidly through the 1950s.

Canned coffee has been popular in Asian countries for many years, particularly in China, Japan, and South Korea. Vending machines typically sell varieties of flavored canned coffee, much like brewed or percolated coffee, available both hot and cold. Japanese convenience stores and groceries also have a wide availability of bottled coffee drinks, which are typically lightly sweetened and pre-blended with milk. Bottled coffee drinks are also consumed in the United States. Liquid coffee concentrates are sometimes used in large institutional situations where coffee needs to be produced for thousands of people at the same time. It is described as having a flavor about as good as low-grade robusta coffee, and costs about 10¢ a cup to produce. The machines used can process up to 500 cups an hour, or 1,000 if the water is preheated.

Coffee can also be incorporated with alcohol in beverages: it is combined with whiskey in Irish coffee, and forms the base of alcoholic coffee liqueurs such as Baileys, Kahlúa, and Tia Maria.
