1, French cup pressing, also known as French kettle, tea maker and French press, originated in France around 1850, and consists of a heat-resistant glass bottle (or transparent plastic) and a metal filter screen with a pressure bar.
2. The bean grinder is a grinding tool. When the motor drives the mechanical cutter to rotate rapidly, the coffee beans are cut and ground into coffee powder.
3. Filter cups can be mainly divided into trapezoidal and conical filter cups, which can be brewed with filter paper, metal filter screen or filter cloth.
4, electronic scale, accurately measure the weight of coffee beans, so that the actual weight and water quantity of coffee beans are maintained at the expected value (powder-water ratio).
5, thermometer, look at the current water temperature, water temperature is a major reason for coffee brewing, too high water temperature may release the bitterness and astringency of coffee cola, too low water temperature will not show the flavor of coffee, and the extraction is insufficient.
Extended data:
Because the coffee beans weighed by electronic scales will leave powder in the bean grinder after grinding, resulting in slight weight error. Therefore, it is necessary to weigh more powder of coffee beans in advance, and then weigh the powder after grinding, so as to minimize the possibility of mistakes.
It is not recommended to use spoons or bean spoons to measure coffee beans, because the different sizes of coffee beans will affect the total weight of each spoon of coffee beans and cause extraction errors.
The principle of making coffee in a press pot: the essence of coffee is released by soaking in water and coffee powder. The suitable coffee is coffee powder, which has strong or weak taste. Wear degree: coarse particles.
