Espresso 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.
A vacuum flask is an insulating storage vessel that slows the speed at which its contents change in temperature. It greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings by trying to be as adiabatic as possible. Invented by James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck. The gap between the two flasks is partially evacuated of air, creating a near-vacuum which significantly reduces heat transfer by conduction or convection. When used to hold cold liquids, this also virtually eliminates condensation on the outside of the flask.
A coffee percolator is a type of pot used for the brewing of coffee by continually cycling the boiling or nearly boiling brew through the grounds using gravity until the required strength is reached. The grounds are held in a perforated metal filter basket.
An espresso machine brews coffee by forcing pressurized water near boiling point through a "puck" of ground coffee and a filter in order to produce a thick, concentrated coffee called espresso. Multiple machine designs have been created to produce espresso. Several machines share some common elements, such as a grouphead and a portafilter. An espresso machine may also have a steam wand which is used to steam and froth liquids for coffee drinks such as cappuccino and caffè latte.
Senseo is a registered trademark for a coffee brewing system from Dutch companies Philips and Douwe Egberts. The system is known for the coffee pods it uses to brew the coffee.
A burr mill, or burr grinder, is a mill used to grind hard, small food products between two revolving abrasive surfaces separated by a distance usually set by the user. When the two surfaces are set far apart, the resulting ground material is coarser, and when the two surfaces are set closer together, the resulting ground material is finer and smaller. Often, the device includes a revolving screw that pushes the food through. It may be powered electrically or manually.
Roasting coffee transforms the chemical and physical properties of green coffee beans into roasted coffee products. The roasting process is what produces the characteristic flavor of coffee by causing the green coffee beans to change in taste. Unroasted beans contain similar if not higher levels of acids, protein, sugars, and caffeine as those that have been roasted, but lack the taste of roasted coffee beans due to the Maillard and other chemical reactions that occur during roasting.
La Marzocco, founded in 1927, Florence, by Giuseppe and Bruno Bambi, is an Italian company specializing in high-end espresso coffee machines. It is based in Scarperia, with branch offices worldwide.
Coffee preparation is the process of turning coffee beans into liquid coffee. While the particular steps vary with the type of coffee and with the raw materials, the process includes four basic steps: raw coffee beans must be roasted, the roasted coffee beans must then be ground, and the ground coffee must then be mixed with hot or cold water for a specific time (brewed), the liquid coffee extraction must be separated from the used grounds, and finally, if desired, the extracted coffee is combined with other elements of the desired beverage, such as sweeteners, dairy products, dairy alternatives, or toppings.
The moka pot is a stove-top or electric coffee maker that brews coffee by passing hot water driven by vapor pressure and heat-driven gas expansion through ground coffee. Named after the Yemeni city of Mocha, it was invented by Italian engineer Otello Amleto Spadini in 1937 who had an agreement with Alfonso Bialetti, an aluminum vendor. It quickly became one of the staples of Italian culture. Bialetti Industries continues to produce the original model under the trade name "Moka Express".
An electric water boiler, also called a thermo pot, is a consumer electronics small appliance used for boiling water and maintaining it at a constant temperature in an enclosed reservoir. It is typically used to provide an immediate source of hot water for making tea, hot chocolate, coffee, instant noodles, or baby formula, or for any other household use where clean hot water is required. They are a common component of Japanese kitchens and the kitchens of many East Asian countries but are found in varying use globally. Smaller units are portable. Some thermo pots are designed with a feature that can purify water.
Dualit is a British manufacturer of kitchen and catering equipment, and coffee and tea capsules. It is known for its range of heavy-duty toasters. It was primarily designed for the commercial catering market, its domestic usage increased during the 1990s
A single-serve coffee container is a container filled with coffee grounds, used in coffee brewing to prepare only enough coffee for a single portion. Single-serve coffee containers come in various formats and materials, often either as hard and soft pods or pads made of filter paper, or hard aluminium and plastic capsules.
An automatic faucet or tap is a faucet equipped with a proximity sensor and mechanism that opens its valve to allow water to flow in response to the presence of a user's hands in close proximity. The faucet closes its valve again after a few seconds or when it no longer detects the presence of a user's hands.
The Easy Serving Espresso pod, is a small packed coffee pod with a paper filter covering for use in a non-grinding espresso machine. The E.S.E. standard was created by Italian Illy in the 1970s and is maintained by the "Consortium for the Development and the Protection of the E.S.E. Standard." It is open to all coffee roasters and machine manufacturers, making it the self-acclaimed "only open system available to the sector for espresso coffee prepared with paper pods".
A coffeemaker, coffee maker or coffee machine is a cooking appliance used to brew coffee. While there are many different types of coffeemakers, the two most common brewing principles use gravity or pressure to move hot water through coffee grounds. In the most common devices, coffee grounds are placed into a paper or metal filter inside a funnel, which is set over a glass or ceramic coffee pot, a cooking pot in the kettle family. Cold water is poured into a separate chamber, which is then boiled and directed into the funnel and allowed to drip through the grounds under gravity. This is also called automatic drip-brew. Coffee makers that use pressure to force water through the coffee grounds are called espresso makers, and they produce espresso coffee.
The Nescafé Dolce Gusto is a coffee capsule system from Nestlé, launched in 2006. The machines are produced by hardware manufacturers Krups and De'Longhi.
iperEspresso is a single-serve capsule system for preparing espresso coffee and espresso-based drinks, developed and patented by Illy.
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, 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.
ISSpresso was the first espresso coffee machine designed for use in space, produced for the International Space Station by Argotec and Lavazza in a public-private partnership with the Italian Space Agency (ASI). ISSpresso was one of nine experiments selected by the Italian Space Agency for the Futura mission. It was installed on the space station between 2015 and 2017, when it was returned to Earth.
