Geyser coffee makers: the history of creation, the principle of action, advice on choosing a French press, dignity, shortcomings, advice from a barista

History:

The first design of the geyser coffee machine was inventedJacques-Augustine Gunde in 1827. It consisted of two vessels connected by a tube and separated by a filter. This system has not changed over time, but the heating has become electric. In his homeland in Italy, this coffee maker is called: Moka Express or Moka Pot. In Russia, it was named after the geyser, because the process of making coffee reminds a geyser.

Differences and types of geyser coffee makers

There are two types of geyser coffee machines:

Electric
Without built-in heating, they simply put on the stove like a kettle.

Operating principle:

Geyser coffee maker operates according to the principlefiltering. It consists of a metal vessel for water, a filter-compartment for ground coffee and a container for ready-made coffee. The cooking process takes place over low heat. Boiling water under the pressure of steam rises through the tube and, passing through the ground coffee, is brewed and enters the upper container. Water absorbs much more substances from coffee beans than with a drip method. But as the boiling water is filtered, the flavor of the drink is lost. Geyser coffee makers create a pressure of 1.5 bar, models with a special valve up to 4 bar.

Capacity of the coffee machine . Geyser coffee machines work only with fullload, so determine in advance the amount of coffee that you are going to boil. Marking the number of cups in Italian-made coffee makers often does not meet the expectations of Russian consumers. In Italy, coffee is drunk very small cups, so it will be appropriate to write a number of cups to multiply the volume by two.
