French pressOriginated from France in the 19th century, it is called French Press in English, and it can also be called "French Press" in Chinese. Although the specific time of its emergence is unclear, in 1852, Frenchmen Mayer and Delforge established the "Smith" company, applied for a patent for a piston filter coffee appliance, and named the product "French Press", which marked the commercialization of the French press.  


The French press is simple and convenient. Simple design refers to the simple structure, simple principle and simple operation of the French press.


wholeFrench pressIt is composed of a heat-resistant glass container and a metal filter with a pressure rod. When making coffee, just soak the coffee powder and hot water in a glass container, and then use a metal filter with a pressure bar to filter the coffee grounds to get a relatively clean cup of coffee. There are three manual steps in the entire coffee brewing process, namely pouring powder, pouring water and pressing the lever.

How to brew a pot of coffee using a French press


becauseFrench pressCoffee is mainly extracted by soaking. Within a fixed volume, a certain amount of water evenly dissolves the substances in the coffee powder. In the extraction process, the main influencing factor is time. The longer the soaking time, the more substances will be extracted from the coffee until it is saturated, or reaches a state where it is difficult to extract. That is, the longer it is soaked, the stronger the taste.

Therefore, first confirm the powder-to-water ratio. Front Street generally recommends a powder-to-water ratio of 1:15 to 1:16. These two powder-to-water ratio ranges have a higher error tolerance. The taste and flavor of most coffees are excellent in this range.

The next step is to determine the grinding thickness of the coffee. It is recommended to choose a coarser grinding size for the French press. Because the French press uses a metal filter for filtration, the gaps are visible to the naked eye. Choosing a coarser grinding size is also for better filtration. The grinding thickness of coffee beans with different roasting degrees is also different. Taking the No. 20 mark screen pass rate as the standard, medium and light roasted coffee beans can be ground finer (pass rate 72-75%), and medium and dark roasted coffee beans can be ground coarser (pass rate 68-71%).

Then come to the water temperature. Because the French press uses immersion extraction, the coffee powder and water are relatively static during the process, so the water temperature will be higher. The water temperature for the same bean French press will be 2-3°C higher than that for hand brewing. It is recommended to use 91-94℃ for brewing light roasted coffee, and 88-91℃ for brewing medium-dark roasted coffee.  The last is the soaking time. As mentioned above, time is very important for the French Press. Through multiple brewing comparisons, Front Street believes that most coffee beans taste best when soaked for about 4 minutes according to the parameters recommended by Front Street. You can also use this set of parameters as a basis to develop your favorite brewing parameters.

The operation process is actually very convenient. Taking 15g of coffee powder as an example, pour the ground coffee powder into the pot, then pour in 225-240ml of hot water, lift the pressure lever, cover the pot lid, and wait for 4 minutes. Then slowly press down the pressure rod so that the metal filter presses 1/4 of the pot body to prevent the fine powder at the bottom from rising to the top.   A simple French press is not just for making coffee simply It can also be used as a cupping tool


The process of making coffee with a French press is very similar to cupping. Both are done by standing and soaking. Many people use a French press to test the quality of coffee beans. The French press brewing method recommended by James Hoffman, the author of "World Coffee Map" is exactly the same as cupping.

Can also be used to make tea


The French press is a simple device that integrates soaking and filtering. It can be used to brew coffee, and of course it can also be used to brew black tea. It is also very convenient to use. If you look closely, you will find that the structures of the tea brewers on the market are very similar to the French press.

 You can even froth milk


The French press can also be used to froth milk. If you want to freeze milk froth, you will need a manual milk frother. In fact, the structure of the manual milk frother is very similar to that of the French press. Whipping the pressure bar of the French press can also froth milk like a milk frother.

Some people may ask: Can a French press make iced coffee?


Front Street was shocked at first, but since some friends asked questions, let’s share what we have learned after several attempts.French pressI would like to share with you the recipe for making iced coffee.  


Imagine


French pressIt is the principle of immersion extraction. When making hot coffee normally and using the same beans, the coffee produced by the French press will be more balanced and thicker in taste than the hand brewed coffee. Therefore, we can also refer to the Japanese ​Pour over​(V60) method to make French press iced coffee. That is, a small amount of hot water is used to soak the coffee, and after extracting the rich hot coffee liquid, it is poured into ice cubes to dilute and cool to form iced coffee.  


21-210Q11Q950A9.jpg


 Considering the need to add ice to dilute the concentration of coffee, it is not suitable to use light-roasted coffee with relatively high acidity to make iced coffee. One reason is that dilution will make the taste thinner, and another reason is that soaking light-roasted coffee with acidity can easily produce bad flavors such as almonds and peanuts. In the end, Front Street decided to use Honduran sherry coffee beans, which are characterized by a mellow taste, rich aroma of vanilla and sherry, and are very suitable for steeping and extraction.  


Extraction plan


① In the preparation stage, prepare a French press, electronic scale, glass, hot water and ice cubes. The amount of powder used is 15 grams. In order to obtain a richer hot coffee liquid, the ratio of coffee powder to hot water is 1:8, and the water temperature is 94°C. In terms of grinding degree, because the French press uses a metal filter to filter, it is not recommended to increase the extraction rate by adjusting the grinding degree. In terms of grinding degree, use medium-coarse grinding (pass rate of No. 20 standard screen 65%).  


176508848979ea8b.jpg


 ② Grind the coffee powder, pour it into the French press, inject 120 grams of hot water (and start timing), and pour the water directly into the center.  


 ③After 30 seconds, use a stir stick to stir the coffee powder layer to increase the coffee extraction rate and form three layers of coffee liquid, coffee powder and coffee foam.  


1765088499f111e5.jpg


 ④Press the lid of the French press and wait for 3 minutes. During this period, you can add 105 grams of ice cubes into the glass.   


⑤After 3 minutes, slowly press down the pressure lever. Let it sit for 1 minute to allow the coffee grounds to settle.  


⑥At the 4th minute, pick up the French press and pour the coffee liquid into the glass with ice cubes.

 In this way, a cup of iced coffee made with a French press is completed. Because it is filtered through a metal filter, the surface still maintains good coffee oil. The vanilla flavor of sherry coffee beans is well reflected, refreshing yet full-bodied.


So, how to disassemble and clean the French press?  


As mentioned in the previous article, the metal filter design of the French Press will retain the coffee's oil. Although it is environmentally friendly and you can enjoy a pot of coffee without spending too much on filter paper, you need to clean the French Press more carefully. If you are lazy and lazy, the remaining coffee oil on the French Press will affect the taste of the next cup of coffee.


1765088125011469.jpg


 The structure of the French press is not complicated, and it mainly consists of a glass bottle, a metal filter and a pressure rod. The disassembled part is mainly the metal filter part. Because it consists of several layers, it is difficult to clean the components inside without disassembling it. First, you need to hold the head of the pressure rod firmly with your hand, and twist and loosen the metal filter part with the other hand. Then clean the remaining components, drain the water and reassemble.


What are some recommendations for delicious coffee beans suitable for a French press?


Take the coffee beans from Front Street as an example. The bean list of FrontStreet Coffee has coffee beans from more than 50 production areas. Each coffee bean has its own characteristics. There is no better coffee bean than Front Street.Indonesian Mandheling coffee beans, Front Street Brazilian Queen Manor coffee beans, Front Street Honduras washed coffee beans. These beans are roasted to a medium-dark degree, and are very suitable for the French press in terms of texture and flavor.


17650882129b5ab3.jpg


Front Street recommends that when choosing coffee beans made with a French press, you may want to consider choosing beans with a better balance, such as Front Street Blue Mountain No. 1, Front Street Bird of Paradise, Front Street Cymbidium, Front Street Brazilian Cerato, etc., which have a darker chocolate and nutty flavor. As for beans with a richer taste, you can try Front Street Strawberry Candy. After soaking and extraction, it can highlight the floral aroma and also show a hint of the fermented aroma of coffee.

The French press is not like hand brewing coffee, which is affected by many factors such as temperature, hand brewing technique, and circle speed. The French press is a coffee appliance that is very suitable for novices to operate. As long as everyone controls it wellbrewTime is enough, because the longer the soaking time, the more substances will be extracted from the coffee until it is saturated, or it is more difficult to reachextractionstate, that is, the longer it is soaked, the stronger the flavor.

In addition, when you taste French press and ​Pour over​(V60) coffee at the same time, you will find that a layer of grease will float on the surface of the coffee brewed by the French press.filter paperMost manual methods of filtration will filter out most of the grease due to the filter paper. Therefore, compared with ​Pour over​(V60) coffee, the taste of French press will be more mellow, but you will also get fine coffee grounds. Because of the design of the metal filter, there will still be "fish that slip through the net", so don't take it too seriously.
