Coffee cup

A coffee cup may refer to a type of container from which coffee is consumed. Coffee cups are typically made of glazed ceramic, and have a single handle, allowing for portability while still hot. Ceramic construction allows to be drunk while hot, providing insulation to the beverage, and quickly washed with cold water without fear of breakage, compared to typical vessels made of glass.
Some types of cups are quite exclusively used for drinking coffee, such as an espresso demitasse or cappuccino cup. Other types of cups commonly used for coffee but are also commonly used for other beverages as well include a teacup or mug. Coffee cups have long been used as promotional items, with corporate logos, messages (e.g., "Worlds Best Dad"), or in the office, a statement of character, political affiliation emblazoned on the side of the mug.
A coffee cup may also refer to disposable cups from which hot beverages (including coffee) are drunk. Disposable coffee cups typically are made of paper or styrofoam. Paper cups at many coffee shops are encircled with a coffee cup sleeve to provide insulation against heat transferred through the surface of the container.
The Anthora paper coffee cup, first produced for coffee-to-go by the Sherri Cup Company in 1963 for the New York metropolitan market, has become so identified with New York City that its image has appeared on the cover of the Manhattan Yellow Pages, and is recognizable in numerous television shows and movies set in New York.
 
After-dinner coffee cups are often served with a small coffee spoon.

Coffea arabica

Coffea arabica (pronounced /əˈræbɪkə/) is a species of Coffea originally indigenous to the mountains of Yemen in the Arabian Peninsula, hence its name, and also from the southwestern highlands of Ethiopia and southeastern Sudan. It is also known as the "coffee shrub of Arabia", "mountain coffee" or "arabica coffee". Coffea arabica is believed to be the first species of coffee to be cultivated, being grown in southwest Arabia for well over 1,000 years.

It is supposed to produce better coffee than the other major commercially grown coffee species but tastes vary, Coffea canephora (robusta). Arabica contains less caffeine than any other commercially cultivated species of coffee. Wild plants grow to between 9 and 12 m tall, and have an open branching system; the leaves are opposite, simple elliptic-ovate to oblong, 6–12 cm long and 4–8 cm broad, glossy dark green. The flowers are white, 10–15 mm in diameter and grow in axillary clusters. The fruit is a drupe (though commonly called a "berry") 10–15 mm in diameter, maturing bright red to purple and typically contain two seeds (the coffee 'bean').

Taxonomy
Coffea arabica was first described by Antoine de Jussieu, who named it Jasminum arabicum after studying a specimen from the Botanic Gardens of Amsterdam. Linnaeus placed it in its own genus Coffea in 1737.
Distribution and habitat
Originally found in the southwestern highlands of Ethiopia, Coffea arabica is now rare there in its native state, and many populations appear to be mixed native and planted trees. It is common there as an understorey shrub. It has also been recovered from the Boma Plateau in southeastern Sudan. Coffea arabica is also found on Mt Marsabit in northern Kenya, but it is unclear whether this is a truly native or naturalised occurrence.Yemen is also believed to have native Coffea arabica growing in fields.

Cultivation
Coffea arabica takes about seven years to mature fully and does best with 1-1.5 meters (about 40-59 inches) of rain, evenly distributed throughout the year. It is usually cultivated between 1,300 and 1,500 m altitude, but there are plantations as low as sea level and as high as 2,800 m. The plant can tolerate low temperatures, but not frost, and it does best when the temperature hovers around 20 °C (68 °F). Commercial cultivars mostly only grow to about 5 m, and are frequently trimmed as low as 2 m to facilitate harvesting. Unlike Coffea canephora, Coffea arabica prefers to be grown in light shade.
Two to four years after planting Coffea arabica produces small, white and highly fragrant flowers. The sweet fragrance resembles the sweet smell of jasmine flowers. When flowers open on sunny days, this results in the greatest numbers of berries. This can be a curse however as coffee plants tend to produce too many berries; this can lead to an inferior harvest and even damage yield in the following years as the plant will favour the ripening of berries to the detriment of its own health. On well kept plantations this is prevented by pruning the tree. The flowers themselves only last a few days leaving behind only the thick dark green leaves. The berries then begin to appear. These are as dark green as the foliage, until they begin to ripen, at first to yellow and then light red and finally darkening to a glossy deep red. At this point they are called 'cherries' and are ready for picking. The berries are oblong and about 1 cm long. Inferior coffee results from picking them too early or too late, so many are picked by hand to be able to better select them, as they do not all ripen at the same time. They are sometimes shaken off the tree onto mats, which means that ripe and unripe berries are collected together.

trees are difficult to cultivate and each tree can produce anywhere from 0.5–5 kg of dried beans, depending on the tree's individual character and the climate that season. The real prize of this cash crop are the beans inside. Each berry holds two locules containing the beans. The coffee beans are actually two seeds within the fruit, there is sometimes a third seed or one seed, a peaberry in the fruits at tips of the branches. These seeds are covered in two membranes, the outer one is called the 'parchment' and the inner one is called the 'silver skin'.
Drawing of Coffea arabica
In perfect conditions, like those of Java, trees are planted at all times of the year and are harvested year round. In less ideal conditions, like those in parts of Brazil, the trees have a season and are harvested only in winter. The plants are vulnerable to damage in poor growing conditions and are also more vulnerable to pests than the Robusta plant.[3] Gourmet coffees are almost exclusively high-quality mild varieties of coffea arabica, like Colombian coffee.



Arabica coffee production in Indonesia began in 1699. Indonesian coffees, such as Sumatran and Java, are known for heavy body and low acidity. This makes them ideal for blending with the higher acidity coffees from Central America and East Africa.
History and legend
Main article: Coffee
According to legend, human cultivation of coffee began after goats in Ethiopia were seen mounting each other after eating the leaves and fruits of the coffee tree. However, in Ethiopia there are still some locales where people drink a tisane made from the leaves of the coffee tree.
 
The first written record of coffee made from roasted coffee beans comes from Arabian scholars who wrote that it was useful in prolonging their working hours. The Arab innovation in Yemen of making a brew from roasted beans, spread first among the Egyptians and Turks and later on found its way around the world.

There is an Ethiopian Coffea arabica that naturally contains very little caffeine. Maria Bernadete Silvarolla, a researcher of Instituto Agronomico de Campinas (IAC), published findings in the journal Nature about these strains of Coffea arabica plants. While beans of normal Coffea arabica plants contains 12 milligrams of caffeine per gram of dry mass, these newly found mutants contain only 0.76 milligrams of caffeine per gram with all the taste of normal coffee.

History of Coffeehouse

A coffeehouse or coffee shop is an establishment which primarily serves prepared coffee or other hot beverages. It shares some of the characteristics of a bar, and some of the characteristics of a restaurant, but it is different from a cafeteria. As the name suggests, coffeehouses focus on providing coffee and tea as well as light snacks. Many coffee houses in the Middle East, and in West Asian immigrant districts in the Western world, offer shisha (nargile in Turkish and Greek), flavored tobacco smoked through a hookah.

From a cultural standpoint, coffeehouses largely serve as centers of social interaction: the coffeehouse provides social members with a place to congregate, talk, write, read, entertain one another, or pass the time, whether individually or in small groups of 2 or 3.

In the United States, the French word for coffeehouse (café) means an informal restaurant, offering a range of hot meals.
History
Storyteller (meddah) at a coffeehouse in the Ottoman Empire
The Ottoman chronicler İbrahim Peçevi reports the opening of the first coffeehouse in Istanbul:
“     Until the year 962 [1555], in the High, God-Guarded city of Constantinople, as well as in Ottoman lands generally, coffee and coffee-houses did not exist. About that year, a fellow called Hakam from Aleppo and a wag called Shams from Damascus came to the city; they each opened a large shop in the district called Tahtakale, and began to purvey coffee.
Various legends involving the introduction of coffee to Istanbul at a "Kiva Han" in the late 15th century circulate in culinary tradition, but with no documentation.
Coffeehouses in Mecca soon became a concern as places for political gatherings to the imams who banned them, and the drink, for Muslims between 1512 and 1524. In 1530, the first coffee house was opened in Damascus,and not long after there were many coffee houses in Cairo.
In the 17th century, coffee appeared for the first time in Europe outside the Ottoman Empire, and coffeehouses were established and quickly became popular. The first coffeehouses reached Western Europe probably through the Kingdom of Hungary, (thus this was the mediator between the Holy Roman Empire and the Ottoman Empire)and appeared in Venice, due to the trafficks between La Serenissima and the Ottomans; the very first one is recorded in 1645. The first coffeehouse in England was set up in Oxford in 1650 by a Jewish man named Jacob at the Angel in the parish of St Peter in the East in a building now known as "The Grand Cafe". A plaque on the wall still commemorates this and the cafe is now a trendy cocktail bar.Oxford's Queen's Lane Coffee House, established in 1654, is also still in existence today. The first coffeehouse in London was opened in 1652 in St Michael's Alley, Cornhill. The proprietor was Pasqua Rosée, the Armenian servant of a trader in Turkish goods named Daniel Edwards, who imported the coffee and assisted Rosée in setting up the establishment in St Michael's Alley, Cornhill.By 1675, there were more than 3,000 coffeehouses in England. Pasqua Rosée also established Paris' first coffeehouse in 1672 and held a city-wide coffee monopoly until Procopio Cutò opened the Café Procope in 1686.This coffeehouse still exists today and was a major meeting place of the French Enlightenment; Voltaire, Rousseau, and Denis Diderot frequented it, and it is arguably the birthplace of the Encyclopédie, the first modern encyclopedia. America had its first coffeehouse in Boston, in 1676.Vienna's first coffee house, The Blue Bottle Coffee House, was opened by the Greek Johannes Theodat (later known as Johannes Diodato) in 1685.Fifteen years later, four Greek owned coffeehouses had the privilege to serve coffee.

Coffeehouse in Palestine.Though Charles II later tried to suppress the London coffeehouses as "places where the disaffected met, and spread scandalous reports concerning the conduct of His Majesty and his Ministers", the public flocked to them. For several decades following the Restoration, the Wits gathered round John Dryden at Will's Coffee House, in Russell Street, Covent Garden.[citation needed] The coffee houses were great social levellers, open to all men and indifferent to social status, and as a result associated with equality and republicanism. More generally, coffee houses became meeting places where business could be carried on, news exchanged and the London Gazette (government announcements) read. Lloyd's of London had its origins in a coffeehouse run by Edward Lloyd, where underwriters of ship insurance met to do business. By 1739, there were 551 coffeehouses in London; each attracted a particular clientele divided by occupation or attitude, such as Tories and Whigs, wits and stockjobbers, merchants and lawyers, booksellers and authors, men of fashion or the "cits" of the old city center. According to one French visitor, Antoine François Prévost, coffeehouses, "where you have the right to read all the papers for and against the government," were the "seats of English liberty."

The banning of women from coffeehouses was not universal, but does appear to have been common in Europe. In Germany women frequented them, but in England and France they were banned.Émilie du Châtelet purportedly wore drag to gain entrance to a coffeehouse in Paris.In a well-known engraving of a Parisian coffeehouse of c. 1700,the gentlemen hang their hats on pegs and sit at long communal tables strewn with papers and writing implements. Coffeepots are ranged at an open fire, with a hanging cauldron of boiling water. The only woman present presides, separated in a canopied booth, from which she serves coffee in tall cups.

Traditional Café Central in Vienna, Austria
The traditional tale of the origins of the Viennese café begins with the mysterious sacks of green beans left behind when the Turks were defeated in the Battle of Vienna in 1683. All the sacks of coffee were granted to the victorious Polish king Jan III Sobieski, who in turn gave them to one of his officers, Jerzy Franciszek Kulczycki. Kulczycki began the first coffeehouse in Vienna with the hoard. However, it is now widely accepted that the first coffeehouse was actually opened by an Greek merchant named Johannes Diodato.

In London, coffeehouses preceded the club of the mid-18th century, which skimmed away some of the more aristocratic clientele. Jonathan's Coffee-House in 1698 saw the listing of stock and commodity prices that evolved into the London Stock Exchange. Auctions in salesrooms attached to coffeehouses provided the start for the great auction houses of Sotheby's and Christie's. In Victorian England, the temperance movement set up coffeehouses for the working classes, as a place of relaxation free of alcohol, an alternative to the public house (pub).

The first Starbucks store, in Seattle, Washington
Coffee shops in the United States arose from the espresso- and pastry-centered Italian coffeehouses of the Italian American immigrant communities in the major U.S. cities, notably New York City's Little Italy and Greenwich Village, Boston's North End, and San Francisco's North Beach. Both Greenwich Village and North Beach were major haunts of the Beats, who became highly identified with these coffeehouses. As the youth culture of the 1960s evolved, non-Italians consciously copied these coffeehouses. Before the rise of the Seattle-based Starbucks chain, Seattle and other parts of the Pacific Northwest had a thriving countercultural coffeehouse scene; Starbucks standardized and mainstreamed this model.

In the United States, from the late 1950s onward, coffeehouses also served as a venue for entertainment, most commonly folk performers during the American folk music revival. This was likely due to the ease at accommodating in a small space a lone performer accompanying himself or herself only with a guitar; the political nature of much of 1960s folk music made the music a natural tie-in with coffeehouses with their association with political action. A number of well known performers like Joan Baez and Bob Dylan began their careers performing in coffeehouses. Blues singer Lightnin' Hopkins bemoaned his woman's inattentiveness to her domestic situation due to her overindulgence in coffeehouse socializing, in his 1969 song "Coffeehouse Blues". In general, prior to about 1990, true coffeehouses were little known in most American cities, apart from those located on or near college campuses, or in districts associated with writers, artists, or the counterculture. During this time the word "coffeeshop" usually denoted family-style restaurants that served full meals, and of whose revenue coffee represented only a small portion. More recently that usage of the word has waned and now "coffeeshop" often refers to a true coffeehouse.

From the 1960s through the mid-1980s, many churches and individuals in the United States used the coffeehouse concept for outreach. They were often storefronts and had names like The Gathering Place (Riverside, CA), Catacomb Chapel (New York City), and Jesus For You (Buffalo, NY). Christian music (guitar-based) was performed, coffee and food was provided, and Bible studies were convened as people of varying backgrounds gathered in a casual "unchurchy" setting. These coffeehouses usually had a rather short life, about three to five years or so on average.[citation needed] An out-of-print book, published by the ministry of David Wilkerson, titled, A Coffeehouse Manual, served as a guide for Christian coffeehouses, including a list of name suggestions for coffeehouses.

List of coffeehouse chains
Coffeehouses in the United States often sell pastries or other food items

Cafes may have an outdoor section (terrace, pavement or sidewalk cafe) with seats, tables and parasols. This is especially the case with European cafes. Cafes offer a more open public space compared to many of the traditional pubs they have replaced, which were more male dominated with a focus on drinking alcohol.

One of the original uses of the cafe, as a place for information exchange and communication, was reintroduced in the 1990s with the Internet café or Hotspot (Wi-Fi).[18] The spread of modern style cafes to many places, urban and rural, went hand in hand with computers. Computers and Internet access in a contemporary-styled venue helps to create a youthful, modern, outward-looking place, compared to the traditional pubs or old-fashioned diners that they replaced. Coffee shops like The Coffee Bean & Tea Leaf and Peet's now offer free Wi-Fi in most stores.
International variation
In the Middle East, the coffeehouse (al-maqhah in Arabic, qahveh-khaneh in Persian or kahvehane or kıraathane in Turkish) serves as an important social gathering place for men. Men assemble in coffeehouses to drink coffee (usually Arabic coffee) or tea, listen to music, read books, play chess and backgammon, and perhaps hear a recitation from the works of Antar or from Shahnameh.

In Australia, coffee shops are also often connected with pop music and country music, and will often have them playing either live or recorded in their shops. Coffeehouses are often gathering places for underage youths who cannot go to bars.
In the United Kingdom, traditional coffeehouses as gathering places for youths fell out of favour after the 1960s, but the concept has been revived since the 1990s by chains such as Starbucks, Coffee Republic, Costa Coffee, Caffè Nero and Pret as places for professional workers to meet and eat out or simply to buy beverages and snack foods on their way to and from the workplace.

In France, a café also serves alcoholic beverages. French cafés often serve simple snacks such as sandwiches. They may have a restaurant section. A brasserie is a café that serves meals, generally single dishes, in a more relaxed setting than a restaurant. A bistro is a café / restaurant, especially in Paris. After the enlightenment era however, coffee houses became increasingly difficult to distinguish from taverns as they ceased to be popular meeting places for scientists and philosophers and were replaced by a growing number of tea gardens which served a drastically different purpose.
In China, an abundance of recently-started domestic coffeehouse chains may be seen accommodating business people. These coffee houses are more for show and status than anything else, with coffee prices often even higher than in the west.

In Malaysia and Singapore, traditional breakfast and coffee shops are called kopi tiams. The word is a portmanteau of the Malay word for coffee (as borrowed and altered from the Portuguese) and the Hokkien dialect word for shop (店; POJ: tiàm). Menus typically feature simple offerings: a variety of foods based on egg, toast, and coconut jam, plus coffee, tea, and Milo, a malted chocolate drink which is extremely popular in Southeast Asia and Australasia, particularly Singapore and Malaysia.
In parts of the Netherlands where the sale of cannabis is decriminalized, many cannabis shops call themselves coffeeshops. Foreign visitors often find themselves quite at a loss when they find that the shop they entered to have a coffee actually has a very different core business. Incidentally, most cannabis shops sell a wide range of (non-alcoholic) beverages.
In modern Turkey and the Arab World, coffeehouses attract many men and boys to watch TV or play chess and smoke shisha. Coffeehouses are called "Ahwa" in the Arab world and combine serving coffee as well as tea and herbal teas. Tea is called "Shay", and coffee is also called "Ahwa". Finally, herbal teas, like hibiscus tea (called karkadeh, or Ennab) are also highly popular.
Espresso bar
The espresso bar is a type of coffeehouse that specializes in coffee beverages made from espresso. Originating in Italy, the espresso bar has spread throughout the world in various forms. A prime example is the internationally known Starbucks Coffee, based in Seattle, Washington in the U.S., although the espresso bar exists in some form throughout much of the world.
The espresso bar is typically centered around a long counter with a high-yield espresso machine (usually bean to cup machines , automatic or semiautomatic pump-type machine, although occasionally a manually-operated lever-and-piston system) and a display case containing pastries and occasionally savory items such as sandwiches.

In the traditional Italian bar, customers either order at the bar and consume their beverages standing or, if they wish to sit down and be served, are usually charged a higher price. In some bars there is an additional charge for drinks served at an outside table. In other countries, especially the United States, seating areas for customers to relax and work are provided free of charge. Some espresso bars also sell coffee paraphernalia, candy, and even music.
North American espresso bars were also at the forefront of widespread adoption of public WiFi access points to provide Internet services to people doing work on laptop computers on the premises.

The offerings at the typical espresso bar are generally quite Italianate in inspiration; biscotti, cannoli and pizzelle are a common traditional accompaniment to a caffe latte or cappuccino. Some upscale espresso bars even offer alcoholic beverages such as grappa and sambuca. Nevertheless, typical pastries are not always strictly Italianate and common additions include scones, muffins, croissants, and even doughnuts. There is usually a large selection of teas as well, and the North American espresso bar culture is responsible for the popularization of the Indian spiced tea drink masala chai. Iced drinks are also popular in some countries, including both iced tea and iced coffee as well as blended drinks such as Starbucks' Frappucino.

A worker in an espresso bar is referred to as a barista. The barista is a skilled position that requires familiarity with the drinks being made (often very elaborate, especially in North American-style espresso bars), a reasonable facility with some rather esoteric equipment as well as the usual customer service skills.


The Expresso bar in the United Kingdom
Haunts for teenagers in particular, Italian-run espresso bars and their formica-topped tables were a feature of 1950s Soho that provided a backdrop as well as a title for Cliff Richard’s 1960 film Expresso Bongo. The first was The Moka in Frith Street, opened by Gina Lollobrigida in 1953. With their ‘exotic Gaggia coffee machine[s],…Coke, Pepsi, weak frothy coffee and…Suncrush orange fountain[s]’[20] they spread to other urban centres during the 1960s, providing cheap, warm places for young people to congregate and an ambience far removed from the global coffee bar standard which would be established in the final decades of the century by chains such as Starbucks and Pret A Manger.

Coffee percolator

A coffee percolator is a type of pot used to brew coffee. The name stems from the word "percolate" which means to cause (a solvent) to pass through a permeable substance especially for extracting a soluble constituent.In the case of coffee-brewing the solvent is water, the permeable substance is the coffee grounds, and the soluble constituents are the chemical compounds that give coffee its color, taste, and aroma. There are two basic types of percolator:
* One which forces boiling water under pressure through the grounds into a separate chamber; and
* One which continually cycles the boiling brew through the grounds using gravity until the required strength is reached.

Coffee percolators once enjoyed great popularity but were supplanted in the early 1970s by automatic drip coffee makers, and more recently by the French press, as well as a renewed interest in espresso coffee. Percolators often expose the grounds to higher temperatures than other brewing methods, and may recirculate already brewed coffee through the beans. As a result, coffee brewed with a percolator is susceptible to over-extraction.In addition, percolation may remove some of the volatile compounds in the beans. This results in a pleasant aroma during brewing, but a less flavourful cup.However, percolator enthusiasts praise the percolator's hotter, more 'robust' coffee, and maintain that the potential pitfalls of this brewing method can be eliminated by careful control of the brewing process.

Brewing process
A non-pressure driven percolator consists of a pot with a small chamber at the bottom which is placed closest to the heat source. A vertical tube leads from this chamber to the top of the percolator. Just below the upper end of this tube is a perforated chamber.

The desired quantity of water is poured into the water chamber of the pot and the desired amount of a fairly coarse-ground coffee is placed in the top chamber. It is important that the water level be below the bottom of the coffee chamber.
After the percolator is placed on the heat source (such as a range or stove), the temperature rises until the water in the bottom chamber boils. While some models may have a one-way aromalock valve at the bottom of the tube which forces some of the boiling water up the tube, most operate on the simple principle that the rising bubbles will force the liquid up the tube. The hot water is distributed at the top over the perforated lid of the coffee chamber. This water then seeps through the coffee grounds and leaves the coffee chamber through the bottom, dropping back into the lower half of the pot. The rest of the colder water at the bottom is meanwhile also forced up the tube, causing this whole cycle to repeat continually.

As the brew continually seeps through the grounds, the overall temperature of the liquid approaches boiling point, at which stage the "perking" action (the characteristic spurting sound the pot makes) stops, and the coffee is ready for drinking. In a manual percolator it is important to remove or reduce the heat at this point (keeping in mind the adage "Coffee boiled is coffee spoiled"). Brewed coffee left on high heat for too long will acquire a bitter taste.

Some coffee percolators have an integral electric heating element, and should obviously never be used on a stove. Most of these automatically reduce the heat at the end of the brewing phase, keeping the coffee at drinking temperature but not boiling.
 
Inventor
 The percolating coffee pot was invented by the American scientist and soldier Count Rumford, otherwise known as Sir Benjamin Thompson (March 26, 1753 – August 21, 1814). He invented a percolating coffee pot following his pioneering work with the Bavarian Army, where he improved the diet of the soldiers as well as their clothes. It was his abhorrence of alcohol and his dislike for tea that led him to promote the use of coffee for its stimulating benefits. For his efforts, in 1791, he was named a Count of the Holy Roman Empire, and granted the formal title of Reichsgraf von Rumford.

The first US patent for a coffee percolator was issued to James Mason of Franklin, MA, in 1865. An Illinois farmer named Hanson Goodrich is generally credited with patenting the modern U.S. stove-top percolator as it is known today, and was granted a patent on August 16, 1889. Goodrich's design could transform any standard coffee pot of the day into a stove-top percolator.

Usage
Percolators are often popular among campers and other outdoorsmen due to the ability to make coffee without electricity. Non-pressure percolators may also be used with paper filters.
Improvements 
The method for making coffee in a percolator had changed very little since its introduction in the early part of the 20th century. However, in 1970 General Food Corporation introduced Max Pax, the first commercially available "ground coffee filter rings”. The Max Pax filters were named so as to compliment General Foods' Maxwell House coffee brand. The Max Pax coffee filter rings were designed for use in percolators, and each ring contained a pre-measured amount of coffee grounds that were sealed in a self-contained paper filter. The sealed rings resembled the shape of a doughnut, and the small hole in the middle of the ring enabled the coffee filter ring to be placed in the metal percolator basket around the protruding convection (percolator) tube.

Prior to the introduction of pre-measured self-contained ground coffee filter rings; fresh coffee grounds were measured out in scoopfuls and placed into the metal percolator basket. This process enabled small amounts of coffee grounds to leak into the fresh coffee. Additionally, the process left wet grounds in the percolator basket, which were very tedious to clean. The benefit of the Max Pax coffee filter rings was two-fold: First, because the amount of coffee contained in the rings was pre-measured, it negated the need to measure each scoop and then place it in the metal percolator basket. Second, the filter paper was strong enough to hold all the coffee grounds within the sealed paper. After use, the coffee filter ring could be easily removed from the basket and discarded. This saved the consumer from the tedious task of cleaning out the remaining wet coffee grounds from the percolator basket.

With the introduction of the electric drip coffee maker in the early 1970's, the popularity of percolators plummeted, and so did the market for the self-contained ground coffee filters. In 1976, General Foods discontinued the manufacture of Max Pax, and by the end of the decade, even generic ground coffee filter rings were no longer available on U.S. supermarket shelves.



Naming convention 
 There exists some controversy as to whether the Moka Pot may be referred to as a percolator. If common usage defines the word then it certainly must be accepted as a common name. Scientifically the term is also correct, with the problem boiling down to the question of "Can pressurised hot water be percolated through a medium?" If the answer is yes then the form of brewing which takes place in the Moka Pot (the forcing of steam-pressurized water through coffee grounds) can be considered a type of pressure-driven percolation and, therefore, the machine which causes it to happen can be termed a "percolator". So, strictly speaking, because the Moka Pot has a percolating compartment it can be referred to - mechanically - as a (machine which) percolates. This forcible driving of hot water through a coffee layer has been referred to as "percolation" in patents. The Moka Pot is described by Saveur as a juxtaposition of percolated coffee and espresso,which acknowledges that percolation is part of the espresso-making process in the Moka Pot. Whilst the Specialty Coffee Association of America recognises six basic methods of brewing (Steeping, Decoction, Percolation, Drip Filtration, Vacuum Filtration and Pressurised Infusion) the differentiation of "Percolation" and "Pressurised Infusion" does not negate the fact that percolation occurs in the Moka Pot (ie: water is filtered through coffee grounds).
