Coffee machines or coffee makers are appliances which is used to brew coffee. There are so many different kinds of devices with various brewing techniques. But in the most common machines, ground coffee is placed in a metal or paper filter which is situated over a ceramic or glass coffee pot. Cold water is then poured into another chamber which heats it up to the boiling point and is directed towards the funnel. This is also known as automatic drip brewing. But have you ever wondered how and when the coffee makers were invented? Read on to know more.
Preparing a cup of coffee has been a very simple process for hundreds of years. The beans were roasted and ground, then put in a pot and water was added. The pot was used to be covered with a lid to start the brewing process. The pots were specially designed to prepare coffee. Usually the pans had an expanded flat bottom which was used to catch sinking ground coffee and a sharp pouring spout was there which trapped floating grinds. There was another designed pot too which had a large lump in the center of it which prevented grounds while coffee was poured.
The infusion brewing system was invented in France in 1710. It used to submerse ground coffee, in a linen bag, in warm water and used to let it ‘infuse’ unless the required brew strength was achieved. During the 19th and the early 20th centuries, adding ground coffee to a pan and boiling it until the perfect smell was considered enough.
There has been a lot of inventions in France in the 18th century. The first ever advanced method of preparing coffee was a coffee filter. It is a utensil for brewing which is made of paper filters. It traps ground coffee and allows the liquid coffee to go through. The first ever filter was invented by a German housewife in 1908.
History of Various Types of Coffee Makers:
Single-Serve Coffee Makers
The single served coffee machines has been very popular from the last few years. It uses a brewing method which makes the exact amount of coffee required for one cup. The brewing process of this machine allows the measured amount of water to pass through the coffee pod and preparing a standard cup of coffee in a cup placed under the outlet. A lot of beverages can be made using this type of machines such as tea, hot chocolate, milk based drinks etc.
The first ever espresso maker was produced by Angelo Morindo from Turin, Italy. He displayed a sample of this machine in Turin at the General Exposition in 1884. His patent was accepted on 1884, May 16. He was awarded by a certificate for his invention named “New steam machine for economic & instantaneous confection of coffee beverage”. A mechanic named LuifiBezzera from Milan, Italy made many improvements to this appliance in 1901. This was titled, “The innovations in machinery to prepare & immediately serve coffee beverage’.
Then the patent was purchased by the founder of “La Pavoni” PavoniDesiderio. He begun to manufacture the machines commercially in Milan, Italy. One espresso maker was produced per day. Today there are a lot of mechanisms used in different espresso makers but all appliances have some common things such as portafilter and grouphead. There is also a steaming wand which helps to froth milk while preparing latte or cappuccino. The espresso makers operate by forcing the water near boiling to pass through a filter and coffee grounds which result in a high concentrated drink called espresso.
Drip Coffee Makers
Drip coffee machines were first invented in America in 1972. The automatic drip brewing method was popularized by the well reputed Mr. CoffeeTM. About 73% of the American homes used an automatic drip coffee maker. In this brewing method, cold water is poured in a completely separate chamber. A heating element warms up the water there. Then the hot water is apportioned on the ground coffee in a filter with the aid of a device like as, the shower head. Then the water drains through the grounds and takes in oils and scent. The grounds are stored in the filter while the liquid coffee drips in a mug.
The first French press was made and patented in France by Attilio Calimani in 1929. A number of alternations to its design was made by FalieroBondanini. He patented his own model of the machine and started producing it in a French clarinet factory. These coffee makers need a little rough grinded coffee than drip machines. The brewing process of a French press involves placing water and coffee together, stirring and leaving it to be brewed for some minutes. Then the plunger is pressed which traps the grounds in the bottom. Coffee experts have also claimed that these makers produce the finest flavor of coffee.
The design of a percolator was patented by James Nason in 1865. The modern age percolator patent was made by Hanson Goorich, a farmer in August 16, 1889. His device was a little different from the today’s stovetop percolator. It operates by warming water in a boiling pot, then the water is passed through a metal pipe and in the brewing basket which has the coffee.The liquids extracted drain from the brewing basket and then drip back into the coffee pot again.
This process is continuously repeated until the liquid flowing in the ground coffee has been steeped enough. The electrification came later and made easy the operation of these machine. Now percolators have a warming element which is powered by electricity, so a stovetop burner is not required. The early percolators were made of glass but the appliances from 1930s were manufactured of copper and aluminum.
