The AeroPress is a manual coffeemaker invented by Alan Adler, founder of AeroPress, Inc. It consists of a cylindrical chamber, and a plunger with an airtight silicone seal, similar to a syringe. Ground coffee beans and water are steeped inside, then forced through a filter at the bottom of the chamber by pressing the plunger down through the chamber. It is capable of brewing highly concentrated coffee, which the manufacturer describes as "espresso style", but can also be used to brew filter strength coffee, or cold brew coffee. [2]
The AeroPress was invented by retired Stanford engineering lecturer Alan Adler. Adler began developing the brewer in 2004, with the intention of reducing acidity and bitterness in his daily cup of coffee. [3] Adler had tried brewing with an espresso machine, pour-over brewer, and french press, but expressed dissatisfaction with each brewer's limited control over parameters such as brew time, water temperature, and grind size. [4] He first began prototyping the AeroPress in his garage. [3]
The brewer consists of a translucent cylindrical chamber, and a plunger with an airtight silicone seal, similar to a syringe. A filter cap is screwed onto the end of the chamber, to hold a small round paper filter in place. The AeroPress comes bundled with several accessories, including a scoop and funnel for loading ground coffee, a stirring paddle, a tote bag, and a plastic holder for storing the included 350 filter papers. Metal filters are available directly from AeroPress as an additional purchase.
The chamber and plunger are moulded out of translucent plastic, tinted a grey colour. Early AeroPress models used polycarbonate, but in 2009 switched to BPA-free copolyester, then in 2014 to polypropylene. [5] The company claims that in lab testing, no BPA leached from these early models into brewed coffee. [5] The lettering changed color several times, but the brewer's design was otherwise unchanged between these versions.
In 2019, AeroPress, Inc. released the AeroPress Go, a travel-sized model with a reduced chamber capacity, smaller accessories, and a mug with a lid.
In 2021 the company received an investment from Tiny, a Canadian holding company. [6]
In 2023, AeroPress, Inc. released the AeroPress Clear. This is constructed of a new material called Tritan, and comes with only the measuring spoon, stir stick, and 100 paper filters. [7]
The device was officially unveiled in November 2005, at the CoffeeFest trade show in Seattle. [3] In the years after its release, it gained a cult following among coffee enthusiasts, who praised it for its flexibility and consistency in brewing. [8]
The World AeroPress Championship is an international fan-led AeroPress brewing competition. The event is a multi-round, elimination tournament, in which competitors have five minutes to brew coffee. It was first held in Oslo, Norway, in 2008, with only three competitors, but grew in popularity each year after. The 2018 competition attracted 3,157 competitors from 61 countries. [9] The 2020 championship was cancelled due to the COVID-19 pandemic. [10] The championship resumed in 2021, with both in-person events and a new online format, in which competitors create and submit their recipe remotely. [11]
According to the instructions, fine-ground coffee is placed in the bottom of the larger cylinder on top of a paper microfilter. Hot water at approximately 176 °F (80 °C) for dark roast coffee or 185 °F (85 °C) for lighter roast [2] is then poured over the coffee; this mixture is stirred for approximately 10 seconds before being forced through the microfilter by pushing the plunger downwards. [12] In the different coffee competitions worldwide (World Barista Championship, Brewers Cup), the coffee is more often ground slightly finer than 'filter grind', and the dose is between 14 and 20 g (0.49 and 0.71 oz), with about 200 to 230 ml (7.0 to 8.1 imp fl oz; 6.8 to 7.8 US fl oz) of water at 80 to 92 °C (176 to 198 °F) and a steeping time of 30 to 60 seconds. [13]
Baristas and coffee drinkers have also developed methods of brewing using the AeroPress with an inverted brewing technique. [14] [15]
In inverted brewing, the plunger is placed into the column from the beginning, close to the "top" of the column, and the entire AeroPress stands upside-down, resting on the top of the plunger. One or two scoops of ground coffee are added, followed by water, and the entire mixture then stirred. While that brews, a filter is placed into the filter cap and moistened to help it stick in place then the AeroPress cap is placed on top of the column and screwed into place. Lastly, once the desired brewing time is complete the AeroPress is either turned right-side-up and plunged normally or held at an angle and plunged horizontally.
This method is more similar to the French press, particularly the extended brewing time in which the grounds and water sit together. This makes it useful for using grinds that wouldn't be optimal in the official method such as coarse grinds that might be used in a French press.
The AeroPress may use a finer grind than other immersion brewers and may take less time to brew coffee, sometimes around 30 seconds. Pressure is used by the AeroPress to aid in extraction, unlike the French press, the Siphon brew, or most other immersion coffee brewers.
Reusable metal mesh filters are available for the AeroPress. In 2017, the manufacturer explicitly recommended against using them, claiming that coffee brewed with paper filters had tested better for taste. [17] In contrast, some immersion brewers, such as the French press, are used almost exclusively with metal filters. As of 2024, the manufacturer's website makes no references to the previously claimed inferiority of metal filters. [18] AeroPress, Inc. in fact now markets its own line of stainless steel mesh filters as of 2024 [update] . [19]
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 French press, also known as a cafetière, cafetière à piston, caffettiera a stantuffo, press pot, coffee press, or coffee plunger, is a coffee brewing device, although it can also be used for other tasks. The earliest known device was patented in 1852 in France by Jacques-Victor Delforge and Henri-Otto Mayer.
Drip coffee is made by pouring hot water onto ground coffee beans, allowing it to brew while seeping through. There are several methods for doing this, including using a filter. Terms used for the resulting coffee often reflect the method used, such as drip-brewed coffee, or, somewhat inaccurately, filtered coffee in general. Manually brewed drip coffee is typically referred to as pour-over coffee. Water seeps through the ground coffee, absorbing its constituent chemical compounds, and then passes through a filter. The used coffee grounds are retained in the filter, while the brewed coffee is collected in a vessel such as a carafe or pot.
A coffee filter is a filter used for various coffee brewing methods including but not limited to drip coffee filtering. Filters made of paper (disposable), cloth (reusable), or plastic, metal or porcelain (permanent) are used. Paper and cloth filters require the use of some kind of filter holder, whereas filters made out of other materials may present an integral part of the holder or not, depending on construction. The filter allows the liquid coffee to flow through, but traps the coffee grounds.
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.
An Aerobie is a flying ring used in a manner similar to a chakram or flying disc (Frisbee), for recreational catches between two or more individuals. Its ring shape of only about 3 mm (0.12 in) thickness makes the Aerobie lighter and more stable in flight than a disc. It can be bent to tune it for straighter flight. Since it has very low drag and good stability, it can be thrown much further than a flying disc. The Aerobie was used to set two former world records for thrown objects.
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.
Mr. Coffee is a brand of automatic drip-brew kitchen coffee machines and other kitchen appliances owned by Newell Brands. Founded in the early 1970s to make a pioneering coffeemaker, Mr. Coffee established itself as the industry's top-selling brand through a promotional relationship with former New York Yankee great Joe DiMaggio, a Major League Baseball Hall of Famer held in high regard by that era's consumers. It subsequently expanded into other kitchen products, such as a related tea maker, juicer, and food dehydrator, and integrated wireless technology into a "smart" version of its coffeemaker. Mr. Coffee is a registered trademark.
Coffee preparation is the making of liquid coffee using coffee beans. 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.
A vacuum coffee maker brews coffee using two chambers where vapor pressure and gravity produce coffee. This type of coffee maker is also known as vac pot, siphon or syphon coffee maker, and was invented by Loeff of Berlin in the 1830s. These devices have since been used for more than a century in many parts of the world. Design and composition of the vacuum coffee maker varies. The chamber material is borosilicate glass, metal, or plastic, and the filter can be either a glass rod or a screen made of metal, cloth, paper, or nylon. The Napier Vacuum Machine by James Robert Napier, presented in 1840, was an early example of this technique. While vacuum coffee makers generally were excessively complex for everyday use, they were prized for producing a clear brew, and were quite popular until the middle of the twentieth century. Vacuum coffee makers remain popular in some parts of Asia, including Japan and Taiwan. The Bauhaus interpretation of this device can be seen in Gerhard Marcks' Sintrax coffee maker of 1925.
Keurig is a beverage brewing system for home and commercial use. The American company Keurig Dr Pepper manufactures the machines. The main Keurig products are K-Cup pods, which are single-serve coffee containers; other beverage pods; and the proprietary machines that use these pods to make beverages.
Alan Adler is an American inventor. His inventions include aerodynamic toys under the Aerobie brand, such as footballs with fins, flying rings and discs, as well as a manual coffee brewing device, the AeroPress. His Aerobie Pro flying ring set several world records for the farthest thrown object.
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.
Coffee extraction occurs when hot water is poured over coffee grounds, causing desirable compounds such as caffeine, carbohydrates, lipids, melanoidins and acids to be extracted from the grounds. The degree to which extraction occurs depends on a number of factors, such as water temperature, brewing time, grind fineness, and quantity of grounds.
The Chemex Coffeemaker is a manual pour-over style glass coffeemaker, invented by Peter Schlumbohm in 1941, manufactured by the Chemex Corporation in Chicopee, Massachusetts.
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 World Brewers Cup is an annual international coffee brewing competition organized by World Coffee Events, an organization founded by the Specialty Coffee Association. The stated goal of the competition is to showcase the craft and skill of filter coffee brewing by hand, promoting manual coffee brewing and quality of service. Contestants qualify for the international competition by winning their respective national championships. As of 2019, there were approximately 40 participating national organizations. The annual location of the event is determined by the World Coffee Events organizing committee, and is typically held in conjunction with the World Barista Championship, the World Coffee Roasting Championship, and the World Latte Art Championship. The first World Brewers Cup was held in 2011 in Maastricht, Netherlands. The 2022 WBrC was held in Melbourne, VIC, Australia.
Edmund Angel Abel, Jr. was an American engineer and inventor who designed and patented the heating element for Mr. Coffee, one of the first automatic drip coffee makers to be introduced to the American consumer market. Mr. Coffee, which was first sold in 1972, soon became the dominant coffeemaker in the United States, reaching sales of approximately $150 million by the late 1970s. Abel's invention, the heating element, brewed a milder coffee than traditional methods, largely replaced the percolator in American homes. Home Furnishings News listed Mr. Coffee as one of the most important household consumer products introduced in the previous seventy-five years in a list published in 2002. Prior to his work on the coffeemaker, he held patents in film developing and aviation. Despite his role in the invention of the Mr. Coffee machine, Abel did not drink coffee.
