Coffee brewing method: the historical origin of the French kettle and the correct operation introduction to beginners

The historical instrument of the French pressure kettle-the French pressure kettle, can also be called the tea maker-FrenchPress. As early as 30 years ago, AlfredPeet, the founder of PeetPeet's Coffee & Tea, a famous roaster in the Berkeley district of the West Bank of the United States, made every effort to promote this convenient, fast and effective brewing method.

Pitt believes that only the use of French pressure can perfectly demonstrate the charming and mellow flavor of deep-roasted coffee. The piston pot method is called the pressurization method in France, the Metro method in the United States and the coffee pot method in Europe, which is a quite good method of coffee blending. Many people like to make coffee in this way because it preserves all the flavor of ground coffee beans, but it is difficult to do so in other ways, which will make the coffee taste like filter paper.

The piston pot is said to have been invented in 1933 by an Italian named Kahliman who sold designs and patents to Switzerland in order to escape Italy during the war. The method of using a piston kettle is very simple. Preheat the pot first. Put in the roasted coffee (about 5 grams per cup), add hot water and stir, soak for 4-5 minutes, then push down the stainless steel piston with mesh to separate the coffee powder from the liquid, and finally pour the coffee juice from the piston pot.

French presss is arguably the easiest way to make coffee (except instant coffee). Frenchpress has always been said to be the best endorsement for lazy coffee. This method of making coffee is very popular in Europe and the United States, but it is often ignored in China and is often described as an authentic tea filling machine. But frenchpress still has a huge following, and these Fans insist that only coffee made from a French kettle can best reflect the original flavor of coffee, because coffee can bloom its original aroma in the simplest way.

It's not expensive! No consumables] take the best quality HARIO heat-resistant glass on the market as an example, the market price of the basic style is only a few hundred yuan, itself does not need filter paper and other consumable materials, careful care and use, can easily reach more than ten years of service life.

[small, suitable for travel] French pressure is very light, weighing only more than 100 grams, during the trip, as long as there is hot water and coffee powder (or coffee beans and compact grinder), you can enjoy a cup of mellow coffee at any time! George, founder of Coffee relationship (CoffeeConnection) and famous in American boutique coffee industry. GeorgeHowell must take French pressure and coffee beans with him when he travels to make sure he can enjoy a good cup of coffee wherever he goes.

[easy to use, easy to clean] "anyone can learn how to brew a cup of strong coffee with French pressure in 30 seconds. "

It performs particularly well with high-quality deep-roasted coffee beans, as long as 1. 5%. Grind the powder and pour in, 2. Flush hot water, 3. Soak for two minutes, 4. Press the pressure bar and pour it out, you can easily enjoy a good cup of coffee!

French pressure cleaning is very easy, rinse the kettle body and filter element after use, and place natural shade to dry! It takes only 20 seconds to complete the cleaning, which is called "one of the easiest coffee equipment in the world to clean and maintain".

[the taste is mellow and full-bodied, the best partner for deep-roasted coffee] Why is the coffee made with French pressure so full-bodied? The answer is simple. French pressure uses the most direct coffee extraction principle-soaking-filtration, and uses a metal (a few brands use plastic) filter, so that the oil and aromatic substances extracted from coffee can pass through the filter unhindered. This characteristic is especially prominent when paired with deep-roasted coffee beans, which can fully show the slippery, sweet, complex and rich characteristics of deep-roasted coffee. Playing French pressure is the easiest time to control, the same situation of beans, grinding, different water temperature of different time has different effects. Generally speaking, the longer the time, the stronger the taste, but it is prone to bitterness, astringency and miscellaneous taste. However, when the five major factors of playing coffee change, controlling time will have unexpected results (for example, deep-roasted beans will get great aroma and sweetness by controlling shorter time. Light-roasted beans need a little more time to extract acidity and aroma). Playing French pressure control time is the most readily available, play to see, there will be a lot of gains! Observe the condition of beans, because French pressure is the easiest equipment to concentrate on the condition of beans. You can look at the amount of yellow foam (crema) of coffee after contact with water, and the coffee suspended on the surface of the water slowly sinks, observing these phenomena can not only learn more about beans, but also have a better understanding of other equipment.

Now let's learn how to use a press to make coffee.

First of all, we need to prepare the following items

1. French pressure kettle: the size of the French pressure pot can be purchased according to the number of people. A 3-cup pressure kettle is used here.

According to the ratio of 10 grams of powder to 180 milliliters of water, our coffee today is 15 grams, and the grinding thickness is "coarse grinding".

two。 Coffee spoon: we choose a coffee spoon with a coffee capacity of 10 grams per flat spoon.

3. A pot of hot water: the best hot water for brewing coffee is 92-96 degrees.

4. A glass of water (drinkable) and an ordinary spoon. Soak the spoon in water and use it to stir the coffee.

5. The most essential thing is, of course, the most suitable ceramic coffee cup for drinking coffee.

Next, let's start making.

1. Warm cup: first use hot water to iron the French kettle. On the one hand, it can remove some of the smell of the previous kettle, and on the other hand, it can increase the temperature of the kettle itself, so that the temperature can be constant in the process of brewing coffee.

two。 Pour in coffee powder: pour the ground coarse-grained coffee powder into the kettle according to proportion.

3. Shake well: gently shake the pressure pot to keep the coffee in the pot on the same level.

4. Pour hot water: pour hot water evenly and slowly, and "circle" clockwise in the process of pouring water, so that the hot water can be soaked into all coffee.

5. Stirring: after pouring hot water, gently stir the coffee in the pot with a prepared spoon or stirring, you can see that a lot of coffee oil will emerge immediately in the process of stirring, and the strong aroma of coffee will be smelled at the same time. Stir until all the coffee touches the water.

6. Adjust the construction: adjust the top of the pressure pot, gently press the pressure bar, so that the filter of the pressure pot is immersed in the coffee, so that all the coffee can be submerged into the water.

7. Set time: set 4 minutes to wait. Judged by many coffee masters, 4 minutes is the best time for French presses to make coffee.

8. Warm cup: like the warm cup of the French pitcher, we hot the cup of our coffee with hot water during the 4 minutes of waiting, so that we can retain the temperature and flavor of the coffee.

9. Press-down assembly: 4 minutes up, slowly press down the pressure bar.

10. Pour out the coffee: when a cup of mellow coffee is made, you can see the thick oil floating on it and the fragrance floating all over the room.
