Modern work pressure, often stay up late, can save yourself late at night and get up, is not what the first heart and ideals, but a cup of mellow and thick coffee ah! This is also the reason why coffee shops are becoming more and more popular nowadays, right?
From 1818, when Mr. Laurens invented the first coffee extractor to today’s coffee machine market is so mature, nearly 200 years have passed. During this time, coffee machines have undergone considerable changes from form to function, and have become increasingly sophisticated.
There are many types of coffee brewing appliances and even more methods. This issue will discuss with you 7 common coffee brewing apparatus and the specific use of the method. The opportunity is rare, hurry to collect Oh.
1. Drip type (filter paper drip type, facecloth drip type)
The so-called drip type, is the first coffee powder into the filter, and then pour the boiling water, dissolved coffee hot water will flow through the filter into the cup.
The typical drip brewing method is the filter paper drip method, which is currently the most used brewing method at home. To use it, simply place the filter paper on the coffee filter cup and pour the residue out of the filter paper after brewing, which is very easy to do.
This method was invented by Mrs. Melitta (Melitta), a German, before 1908, and because of its ease of use and the ability to drink smooth coffee without coffee grounds, this brewing method quickly became popular worldwide and has been popular for 110 years now.
Melitta registered her invention with the Royal Patent Office, a copper coffee filter cup with a hole at the bottom of the arch, and was the world’s first filter coffee cup, named the “Melitta Cup”. Later, people also called the single-hole filter cup Melitta cup.
This seemingly simple brewing method, the operation is still a certain degree of difficulty, in order to brew a good quality of stable coffee, need to practice repeatedly.
It looks like a great model, right? The coffee dripping through the filter paper, as if it is filtering and precipitation of their own, such a process to experience it in person to feel the beauty of it!
Commercially available ear packets also belong to the filter paper drip type
The filter paper drip filter is made of paper, while the facecloth drip brewing method uses facecloth as the filter. Although the latter is more difficult to operate, this brewing method is very popular in some Japanese coffee shops or among coffee lovers.
Applicable coffee: Strong and light flavored coffee powder, not instant coffee
Grind degree: medium-fine grind
2. Drip coffee machine
Is a classic drip filter, also known as a normal pressure coffee machine. Easy to start simple and efficient, ideal for home and office use. There is a funnel on top, which is used to put filter paper and coffee powder. The price is moderate, but the coffee filter paper consumption is large.
Grind degree: the general coarse and fine grind degree is determined by the equipment chosen
3. French pressure pot (piston type)
This is a simple brewing apparatus consisting of a heat-resistant glass carafe (or clear plastic) and a metal filter with a pressure bar, which originated in France around 1850. Initially, it was mostly used for brewing black tea, so some people also called it a tea brewer.
The ground coffee powder is put into the coffee pot, hot water is poured in, and after a period of time, the filter is squeezed and the coffee powder is separated and filtered out from the bottom of the container, which is a kind of brewing method that is a bit troublesome to clean but easy to operate.
This dipping method is characterized by easy control, change the contact time between hot water and coffee powder, for coffee lovers who have personal requirements for the taste of coffee, this method is very suitable.
Applicable coffee: Coffee powder with both strong and light flavors, can also be used to brew black tea
Grind degree: coarse granular
4. Siphon coffee potThe siphon coffee pot has a very distinctive shape: first pour water into the spherical glass container at the lower end, then heat the water underneath the glass container until it boils, and insert the funnel with the coffee powder into the glass container. After that, the water will be sucked up as soon as it boils, and then the extraction of coffee will begin. After a certain time, as soon as the heating is stopped, the water vapor that has just expanded will contract when it gets cold, and the coffee that was originally in the glass appliance will be sucked up into the flask.
The residue produced during the extraction will be blocked by the filter at the bottom of the glass appliance, and it will be filtered instantly to separate the coffee liquid from the powder. Although it is more troublesome in terms of appliance maintenance, the brewing method is simple to operate.
This is a very scientific way of coffee extraction. Firstly, it has a more suitable extraction temperature, the water in the lower pot rises to the upper pot at exactly 92°C, which is the most suitable extraction temperature for coffee; secondly, the combination of natural steeping extraction and pressure extraction in the reflux process achieves a more perfect coffee extraction effect.
The siphon coffee pot has a charm that other coffee appliances do not have, it has a unique visual effect. Not only does the shape have character, but even the moment the coffee is sucked through the filter into the flask after the flame is turned off is a sight to behold.
Grind degree: medium – coarse grind
5. Royal Belgian Coffee Pot
The siphon tube of the Royal Belgian Coffee Pot, which is a combination of siphon and moka (more on that later), is worth exploring, combining several natural forces: fire, steam, pressure, and gravity.
From the outside, it looks like a symmetrical balance, with a kettle and alcohol lamp on the right, and a glass coffee pot with ground coffee on the left, connected at both ends by a thin tube curved like a cane. When the kettle is filled with water, the balance is out of balance to the right, and when the water rolls, the steam rushes away from the piston in the thin tube, rushing down the tube to the glass pot, with the coffee powder waiting at the other end to meet.
When all the water in the pot turns into water vapor and runs to the left, after fully mixing with the coffee powder, because of the siphon principle, the hot coffee will pass through the filter at the bottom of the thin tube and return to its old home on the right, leaving the dregs at the bottom of the glass pot. At this point, open the tap of the kettle and the aromatic coffee is out of the oven~
Grind degree: medium – coarse grind6. espresso coffee machine (espresso machine)The principle of the espresso machine is to use a mixture of high-pressure steam and water to quickly pass through the coffee layer and instantly extract the coffee, so that the temperature of the coffee is very high, the content of caffeine and other impurities is very low, and the taste is rich.
Development so far, espresso machines have been fully automated, the function is also more comprehensive, you can do a lot of fancy coffee, the disadvantage is that the price is higher. The price of commercial machines is even as high as 100,000 or more, and the price of home espresso machines is also generally higher, usually up to about 10,000 yuan.
Grind degree: medium-fine grind (too fine will cause excessive extraction of coffee, making the taste too bitter)7. Moka potIn 1933, an Italian named Bilotti invented the moka pot, from then on espresso coffee officially from the coffee house into the home. The moka pot is a tool used to extract espresso coffee, divided into two layers of structure, placed in the lower part of the water boiling boiling through a mesh filter with coffee powder sprayed into the upper part of the pot.
Although hot water can be injected into the coffee powder without the use of air pressure, this is not strictly speaking an espresso extraction, but is closer to a drip type. However, the coffee made by the moka pot still has the consistency and flavor of espresso.
Moka Pot Illustration
Today, the appearance of the moka pot has changed a bit, but the basic structure has not departed from the prototype.
In terms of material, most of the moka pots are made of aluminum or stainless steel. Aluminum products are cheap and light weight, with fast heat conduction, which is its advantage. However, aluminum products are not easy to clean, easy to rust, and require more effort in preservation.Stainless steel moka pots do not have this problem, easy to clean, in terms of service life, more long-lasting. In addition, stainless steel moka pots can be heated on induction or gas stoves, making it more convenient to use.
Grind degree: medium-fine
A variety of coffee derived from espresso, cappuccino, latte, mocha, etc., can be made from coffee extracted by the moka pot as a base. Therefore, it can be said that having a moka pot is equivalent to having half a cafe! Want to play coffee at home at the best price, you can try the moka pot first.
