The history of the French kettle

The French press (Frech press), also known as the French filter press, originated in France in 1850, a simple brewing apparatus consisting of a heat-resistant glass bottle (or transparent plastic) and a metal filter with a pressure bar. It was originally used to brew black tea, so it is also called a tea maker.

Patent in March 1852, a horsepower metalworker and a businessman jointly obtained a patent called "Piston filter Coffee device". The patent describes a metal can connected to a movable rod with holes in the bottom of the rod and a layer of flannel on each side. After pulling the movable rod manually, the movable rod moves in the cylindrical container. "push the lever to the bottom," the inventor wrote. "the filtered coffee is left above the lever, refreshing."

But it was not until the late 1920s that a Milan company registered a patent for a modified version of the French kettle that it became well known. Within a few years after the registration of the patent, the company gradually improved the design of the French kettle. In 1935, they introduced a perfect pressure kettle-the disk-shaped structure at the bottom of the piston was fitted with a spring to keep the disk flush with the bottom of the container. But the popularity of French kettles in the United States took a long time. In the early 1980s, some Americans learned from the British to use French presses and called them cafe è re, while others called them "French piston coffee machines."

In 1993, Florence Fabricant introduced this "French pressing method" to readers in the New York Times, which said that the press pot is the favorite device used by coffee connoisseurs.

What is the principle of French press? coffee is made by completely soaking the coffee in the kettle, and then using a pressure bar with a metal filter to separate the coffee from the coffee grounds. The coffee obtained by this method is very mellow, can increase the price, texture and oil, and the final coffee is quite clean.

How to use a pressure pot to make coffee?

1, the degree of grinding: it is easy to over-extract coffee from the pressure pot, so the degree of grinding is thicker, which is generally required to be a little larger than the particles of edible sugar. If the degree of grinding is too fine, the extraction of coffee will be very fast. At the same time, small coffee dregs will pass through the metal filter to make the coffee less clean to drink.

2, coffee brewing ratio: coffee brewing ratio is the ratio of coffee to water. The common brewing ratio is from 1:15 to 1:18, which means 15g of coffee needs to be brewed with 225g of water. If you want to use a pressure kettle at home, you can adjust the brewing ratio according to your own taste.

3, water temperature: the water temperature can be brewed with hot water at about 92-94 degrees Celsius.
