Nespresso Vertuo Coffee & Espresso Machine by Breville with Aeroccino Milk Frother, Chrome

Coffee is a beverage brewed from roasted, ground coffee beans. Darkly colored, bitter, and slightly acidic, coffee has a stimulating effect on humans, primarily due to its caffeine content. It has the highest sales in the world market for hot drinks.

Coffee production begins when the seeds of the Coffea plant's fruits (coffee cherries) are separated to produce unroasted green coffee beans. The beans are roasted and then ground into fine particles. Coffee is brewed from the ground roasted beans, which are typically steeped in hot water before being filtered out. It is usually served hot, although chilled or iced coffee is common. Coffee can be prepared and presented in a variety of ways (e.g., espresso, French press, caffè latte, or already-brewed canned coffee). Sugar, sugar substitutes, milk, and cream are often added to mask the bitter taste or enhance the flavor. There are also various coffee substitutes.

Though coffee is now a global commodity, it has a long history tied closely to food traditions around the Red Sea. The earliest credible evidence of coffee drinking as the modern beverage appears in modern-day Yemen in southern Arabia in the middle of the 15th century in Sufi shrines, where coffee seeds were first roasted and brewed in a manner similar to how it is now prepared for drinking. The coffee beans were procured by the Yemenis from the Ethiopian Highlands via coastal Somali intermediaries, and cultivated in Yemen. By the 16th century, the drink had reached the rest of the Middle East and North Africa, later spreading to Europe.

The two most commonly grown coffee bean types are C. arabica and C. robusta. Coffee plants are cultivated in over 70 countries, primarily in the equatorial regions of the Americas, Southeast Asia, the Indian subcontinent, and Africa. Green, unroasted coffee is traded as an agricultural commodity. The global coffee industry is massive and worth $495.50 billion as of 2023. In the same year, Brazil was the leading grower of coffee beans, producing 35% of the world's total, followed by Vietnam and Colombia. While coffee sales reach billions of dollars annually worldwide, coffee farmers disproportionately live in poverty. Critics of the coffee industry have also pointed to its negative impact on the environment and the clearing of land for coffee-growing and water use.

Espresso ( , Italian: [eˈsprɛsso]) is a concentrated form of coffee produced by forcing hot water under high pressure through finely ground coffee beans. Originating in Italy, espresso has become one of the most popular coffee-brewing methods worldwide. It is characterized by its small serving size, typically 25–30 ml, and its distinctive layers: a dark body topped with a lighter-colored foam called crema.

Espresso machines use pressure to extract a highly concentrated coffee with a complex flavor profile in a short time, usually 25–30 seconds. The result is a beverage with a higher concentration of suspended and dissolved solids than regular drip coffee, giving espresso its characteristic body and intensity. Despite the stronger taste profile, espresso typically contains fewer milligrams of caffeine than an equal serving of drip-brewed coffee.

Espresso serves as the base for other coffee drinks, including cappuccino, caffè latte, and americano. It can be made with various types of coffee beans and roast levels, allowing for a wide range of flavors and strengths. The quality of an espresso is influenced by factors such as the grind size, water temperature, pressure, and the barista's skill in tamping the coffee grounds.

While espresso contains more caffeine per unit volume than most coffee beverages, its typical serving size results in less caffeine per serving compared to larger drinks such as drip coffee. The cultural significance of espresso extends beyond its consumption, playing a central role in coffee shop culture and the third-wave coffee movement , which emphasizes artisanal production and high-quality beans.

A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems.

Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage.

Modern machines are complex systems that consist of structural elements, mechanisms and control components and include interfaces for convenient use. Examples include: a wide range of vehicles, such as trains, automobiles, boats and airplanes; appliances in the home and office, including computers, building air handling and water handling systems; as well as farm machinery, machine tools and factory automation systems and robots.

Milk is a white liquid food produced by the mammary glands of mammals. It is the primary source of nutrition for young mammals (including breastfed human infants) before they are able to digest solid food. Milk contains many nutrients, including calcium and protein, as well as lactose and saturated fat. Immune factors and immune-modulating components in milk contribute to milk immunity. Early-lactation milk, which is called colostrum, contains antibodies and immune-modulating components that strengthen the immune system against many diseases. The US CDC agency recommends that children over the age of 12 months (the minimum age to stop giving breast milk or formula) should have two servings of dairy (milk) products a day, and more than six billion people worldwide consume milk and milk products.

As an agricultural product, dairy milk is collected from farm animals, mostly cattle. In 2011, dairy farms produced around 730 million tonnes (800 million short tons) of milk from 260 million dairy cows. India is the world's largest producer of milk and the leading exporter of skimmed milk powder. New Zealand, Germany, and the Netherlands are the largest exporters of milk products. Between 750 and 900 million people live in dairy-farming households.

Nestlé Nespresso S.A., trading as Nespresso, is an operating unit of the Nestlé Group, based in Vevey, Switzerland. Nespresso machines brew espresso and coffee from coffee capsules (or pods in machines for home or professional use), a type of pre-apportioned single-use container, or reusable capsules (pods), of ground coffee beans, sometimes with added flavorings. Once inserted into a machine, the capsules are pierced and processed. Water is then forced against a heating element at high pressure meaning that only the quantity for a single cup is warmed. By 2011 Nespresso had annual sales in excess of 3 billion Swiss francs. The word Nespresso is a portmanteau of "Nestlé" and "Espresso", a common mechanic used across other Nestlé brands (Nescafé, BabyNes, Nesquik).

All Nespresso coffee is roasted, ground and encapsulated in one of three factories in Switzerland (Avenches, Orbe, and Romont), but the company sells its system of machines and capsules worldwide, as well as the VertuoLine system in North America and certain other countries.
