Geyser coffee machine and French press: history of creation, the main principle of action, advantages and disadvantages

The geyser coffee maker was created quite a long time and around the world enjoys well-deserved recognition from those who are not indifferent to coffee. The first car of this type was invented by the French jeweler Jacques - Augustine Gunde. This profession is characterized by a meticulous and very filigree approach, attention to detail, all these qualities he showed during the invention of such a coffee maker. In models of this type, the beverage is brewed by repeatedly passing hot water through a layer of ground coffee. A peculiar feature of the design was the invention of a new type of water supply to a brewing chamber under sufficiently high pressure. Due to this, the effect of spraying hot water over a layer of ground coffee was achieved.

Until today, the geyser coffee machine has been continuously improved and eventually reached a modern level. At the moment, manufacturers equip this device with a thermal control device, it allows controlling the operation of heating elements and protecting them from excessive overheating. It is also necessary to prevent the machine from operating in the absence of cold water in the tank. The main detail, without which there is not a single geyser coffee machine, is a removable electric heater. It is needed for direct heating of water before it enters the "geyser".

A geyser coffee machine requires knowledge of certain subtleties, the following of which will prevent damage to the device. In order to enjoy properly brewed coffee in a similar device, you need to grind the coffee well and fill it with a mesh cylinder to a certain level. The amount of filled coffee in grams can be recognized by the divisions marked on the acceptance cylinder. A very important point - the water should not reach the mesh cylinder itself, where the coffee is filled.

Also, along with the geyser in today's market, there are different types of coffee makers. These types of devices are divided into filtration, espresso, and also combined action machines, in which there is both a filter type of a coffee maker and an espresso type. In addition, there is a device called the French press.

This type of coffee machine is a piston action machine, which was developed by a French company in 1920. It is nothing more than a coffee pot, which is based on a glass cylinder, heat-saving and rather heat-resistant, as well as a piston in which the lower part is connected to a metal filter of the mesh type. This filter densely adjoins the walls of the coffee pot, in turn, the upper part of the filter passes through the lid. Prepared coffee in this apparatus is quite simple, you need to fill the ground powder in the coffee machine, pour water at the right temperature and insist about five minutes. Then smoothly lower the piston, thereby collecting coffee grounds on the bottom, and the drink itself remains on top. This model is ideal for fans to relax in nature, as boiling water for brewing can be cooked on a fire or on a spirit lamp. With all this, this coffee maker is compact in size and weighs in the range of 300 grams.

Moka Express is a kind of geyser coffee maker, which was born in Italy. Also, there are similar types of devices that do not require electricity in their work. They are simply put on the tile or on another heat source, and you can wait for the boiling water. In other respects, the principle of operation is analogous to the electrical version.

According to the manufacturers, the flask for the type of coffee machine of the type described has acceptable thermal insulation properties. It is able to maintain a tolerable temperature for coffee consumption for one hour. Also, another undoubted advantage is a low price unlike electric coffee makers. Among the merits, one can also note the uselessness of additional filters and other parts requiring capital investments.

To date, almost all manufacturers of household appliances produce coffee makers of various types. But the most popular manufacturers of geyser coffee makers, for quite some time, are the Italian firms - GAT, Pedrini and Bialetti.
