Coffee makers are common kitchen appliances that we use to make coffee without the hassle of boiling water separately. Many different styles of coffee makers use many different brewing standards. Typical units use coffee grounds that are typically placed on a paper filter in a funnel that is then placed over a coffee pot made of glass or ceramic.
For many centuries, producing a cup of coffee was a deceptively trouble-free process. During the 19th and 20th centuries, it was considered sufficient to put ground coffee in boiling water, leave it on the heat until the aroma was just right, and pour the brew into a cup.
The first modern process of brewing coffee is also known as drip brewing. It is over a century old and its design has changed only slightly. The Biggin, which began in France in the 19th century, has two levels. It has a coffee pot with coffee in the compartment above where water was poured to be emptied into the compartment that is the coffee pot below. During the same period, a French creator built the pump percolator. It is a device in which boiling water in a base chamber is pushed up a pipe and then drips or percolates through the coffee grounds back into the base chamber.
The first espresso machine was made in France in 1882.
Instant coffee was invented by the Japanese-American chemist Satori Kato of Chicago in the 20th century. English chemist GC Washington created the first bulk-produced instant coffee in 1906. He was residing in Guatemala when he made the observation about the dry coffee in his pot. After experimenting, he developed Red E Coffee, which is the brand name of his instant coffee.
Coffee filter paper was patented on June 20, 1908. Before the end of the same year, Mellitta and Hugo Bentz founded the Melitta Bentz Company. The following year, they sold more than a thousand coffee filters in Germany. Also, in 1937, the company patented the filter and in 1962, vacuum packaging.
In 1938, freeze-dried coffee (Nescafé) was introduced.
Then Ernest Illy developed the first automatic espresso machine in 1933.
Later, in 1946, the modern coffee maker was invented by an Italian named Achilles Gaggia. He created a high-pressure machine using a spring-loaded lever structure.
Although some coffee pots tended to be standardized on unitary shapes, some still displayed a wide selection of design variations in the early 20th century. Above all, the vacuum coffee maker, which required two different chambers connected in an hourglass design, motivated and inspired manufacturing designers.
Later, coffee makers began to adopt a more consistent structure that coincided with a large increase in the level of production needed to meet consumer demand after the war. Plastic and amalgamated supplies began to replace metal, efficiently, in the 1970s. Throughout the 1990s, customers insisted on more attractive machine designs to match upscale contemporary kitchens. This resulted in a new trend of newly designed coffee makers offering a greater variety of existing shapes and colors.
