What are the appropriate parameters of coffee grinding thickness, water temperature, water quantity and time in the production method?

No matter what utensils are used to brew coffee, it is necessary to grind the coffee beans into coffee powder and then brew them. Due to different utensils, the grinding thickness of coffee powder is also different. Qianjie Coffee has a certain standard for grinding coffee powder. We all know that if you want to drink a delicious cup of coffee, the grindness of coffee powder, water temperature and the quality of coffee beans are all factors that affect the flavor of coffee. Although the French kettle is easy to operate, it is also the best way to reflect the advantages and disadvantages of coffee beans, so it is recommended to use high-quality coffee beans.

Of course, there are a lot of details in the brewing of coffee, otherwise a delicious cup of coffee will easily change its flavor. Qianjie now to introduce to you is a very simple coffee brewing equipment-French pressure pot, there is another name, that is: lazy people, very suitable for novice coffee! What are the standards for the grinding degree and water temperature of coffee powder corresponding to this coffee utensil? Let's find out one by one in front of the street. Of course, it can also be adjusted slightly according to individual taste.

Let's first take a look at the French kettle:

French press pot originated in 19th century France, English for French Press, Chinese can also be called "French filter press". Although the exact date of appearance is not clear, in 1852, the Frenchman Mayer and Delforge founded Smith, applied for a patent for piston filter coffee utensils, and named the product "French Press", which marked the emergence of the commercialization of French pots. The French pressing kettle has a simple and convenient design, which refers to the simple structure, simple principle and simple operation of the legal pressing kettle. The whole kettle is composed of a heat-resistant glass container and a metal filter with a pressure bar. When making coffee, just soak the coffee powder and hot water in a glass container, and then filter the coffee grounds with a metal filter with a pressure bar to get a relatively clean cup of coffee. The manual operation part of the whole coffee brewing process consists of three steps, namely, pouring powder, pouring water and pressing rod.

What kind of powder does the French kettle use? The French kettle is rough grinding.

The grindability of coffee powder is related to the roasting degree of coffee beans. The extraction method of the pressure kettle (the pass rate of the No. 20 screen 68-75%) is very similar to that of the cup test, which is mainly soaked, so the degree of grinding selected coincides with the height measured by the cup; there is another reason for choosing thicker grinding particles. it is because the method pressure filtration is the use of metal filter, the gap is visible to the naked eye, the thicker choice is also for better filtration. The grinding thickness of coffee beans with different roasting degrees is also different, medium and shallow roasted coffee beans can choose finer grinding (pass rate 72-75%), and medium-deep roasted coffee beans can be ground thicker (pass rate 68-71%).

Qianjie Coffee Grinding thickness Standard sieve pass rate:

Fine ice drop > hand flush (medium shallow, medium) race wind 80% > Mocha American drip 75-80% > hand flush (medium depth) 75% > cup test 70-75% > method pressure 65-70% thick

The extraction mode of the pressure pot is similar to the cup test, both are immersion extraction, the advantage is to minimize the human factors, can best reflect the original taste of beans, and the flavor of coffee will be more concentrated. What are the human factors? For example, hand-brewed coffee can change the performance of coffee flavor through the speed of water injection, or different filter cups can make coffee flavor differently. But there is no such saying in the French kettle. There are only three kinds of coffee flavor that can affect the coffee made by the French kettle: grinding degree, water temperature, and soaking time.

Qianjie pressure pot brewing coffee is suggested: because the method pressure pot mainly depends on soaking to extract coffee, in a fixed capacity, a certain amount of water evenly dissolves the substance in the coffee powder. In the process of extraction, the main influencing factor is time, the longer the soaking time, the more substances extracted from the coffee until saturated, or to a more difficult state of extraction, that is, the longer the soak, the stronger the flavor.

Then to the water temperature, because the kettle is soaked and extracted, the coffee powder and water are relatively static, so the water temperature will be higher, and the water temperature of the same bean kettle will be 2-3 ℃ higher than that of hand flushing. It is recommended to use 91-94 ℃ for light roasted coffee in brewing and 88-91 ℃ for deep-roasted coffee. Finally, there is the soaking time, which is very important for the French kettle. Through the comparison of brewing for many times in Qianjie, it is considered that the taste of most coffee beans is the best when soaked for about 4 minutes according to the parameters recommended by Qianjie. You can also use this set of parameters as a model to develop your favorite brewing parameters.

In fact, the operation process is really very convenient. Take 15g coffee powder as an example, pour the ground coffee powder into the pot, then pour into the hot water of 225-240ml, pull up the pressure bar, cover the kettle and wait for 4 minutes. Then slowly press down the pressure bar to make the metal filter press the 1x4 of the kettle body to prevent the fine powder from the bottom from surging to the top.

Finally, the coffee was poured into a warm cup in time and tasted. Some friends may not pour out the coffee in time and let the coffee continue to soak in the water, so that the coffee can easily be overextracted.

The French kettle can also be used to make tea.

The soaking and filtering integrated simple apparatus of the pressure pot can be used to brew coffee, of course, it can also be used to brew black tea, and it is also very convenient to use. It is carefully found that the structure of the tea maker sold on the market is very similar to that of the kettle.

For the brewing of the French kettle, Qianjie suggests that when choosing coffee beans, you might as well consider choosing beans with a good balance, with dark chocolate and nutty flavors, such as Brazil, Mantenin and Colombia. as for beans with rich taste, such as Essex Coffee, Qianjie is not recommended. Because the kettle is soaked and extracted, if the flavor level of beans is rich, it is more difficult to show the rich levels of beans. Because the oil determines the aroma and flavor of the coffee, which also shows from the side: the coffee made by the French filter press has better aroma and stronger taste when roasted deeply.
