Filter Coffee | Make your own coffee, brewing it yourself is the most relaxing!

In an era when all kinds of coffee machines are everywhere, hand-brewed coffee, which uses simple utensils and pays attention to hand-feeling skills, is like a return to nature. It has spread from Japan, which pursues exquisite culture, and has fascinated many coffee experts and lifestyle experts. As the name suggests, hand-brewed coffee is to pour hot water on coffee powder and extract coffee through filter paper and filter cup. The whole brewing process takes about 3 to 4 minutes. Since the flow rate, direction and temperature of hot water are all controlled by the brewer, the flavor of the coffee brewed almost every time is different. Although the utensils are simple, it is very particular about technique and experience.

Hand-brewed coffee equipment

Bean grinder: Freshly ground coffee is the freshest. The particle size and uniformity of coffee powder are also key factors affecting the flavor of hand-brewed coffee. The powder particles suitable for hand-brewed coffee are about the size of fine sugar. The more uniform the particles, the better the taste of the brewed coffee.

Filter paper: Different filter cups have their own suitable filter paper. Filter paper can absorb some of the coffee's flavor and oil. Unbleached filter paper may have some paper smell.

Pour-over kettle: There are various sizes and materials of pour-over kettles on the market, and you can choose according to your needs. The size of the mouth of the kettle will affect the brewing results because it is related to the amount of water output. Beginners are generally recommended to use a narrow-mouthed kettle (as shown below), which is easier to control. In addition, each type of pour-over kettle is suitable for different heating methods (induction cooker or gas stove), so pay special attention when purchasing.

Filter cup: The size and material of the filter cup are also different. There are three main shapes: fan-shaped, cone-shaped and wave-shaped. The size of the filter diameter at the bottom of the filter cup will affect the flow rate of the extracted coffee, which in turn affects the flavor of the coffee. The fan-shaped filter cup has a small filter diameter, a slow flow rate, and a mellower taste; the cone filter cup has a large filter diameter, a fast flow rate, and a lighter taste; the wave filter cup has a flat bottom and is paired with a special wave filter paper, so the filtered coffee has the most uniform taste. What is more special is the metal filter cup, which does not need to be used with filter paper. It can retain more coffee oil and has a stronger taste, but some finer coffee powder may not be filtered out.

Coffee pot and coffee cups: used to hold filtered coffee, it is best to heat them first to maintain the coffee temperature.

Auxiliary equipment: Electronic scales, thermometers and timers can make the coffee brewing process more accurate.

Characteristics of Hand-Poured Coffee

Fast extraction speed and efficiency: Compared with other coffee brewing methods, hand-brewed coffee has fresh hot water continuously passing through the coffee powder during the extraction process, which makes the extraction speed faster and can extract more substances from the surface of the coffee. However, due to the fast speed, if it is not well controlled, it may be over-extracted. This is the same as frying fish in a pan over high heat. The fish has a large heating area, but if it is not well controlled, it may burn.

There are many influencing factors: Although it is only a process of a few minutes, the water flow rate, water temperature, coffee powder particles, filter cup shape, etc. will affect the final flavor of the coffee, so sufficient research and preparation are required before brewing.

Coffee has diverse flavors: Coffee brewed under different conditions has different flavors, and different types of beans are suitable for different conditions.

Tips: Brewing techniques will make the flavor of coffee different, so the extraction time when using filter paper brewing should not be too long, otherwise the coffee will release too much sourness and bitterness.

Steps:

1. Press the filter paper at the joint and open it to place it on the filter cup.

2. Spread the coffee powder on the filter paper and then stack it on the coffee pot.

3. Pour a small amount of water from the hand brewing kettle into the filter cup and wait for the coffee powder to expand before continuing to brew.

4. When brewing, pour out the hot water at a slow speed and maintain a fixed water volume, using a circular motion.

5. Observe the brewing status of the coffee in the filter cup and allow the coffee powder to be fully steamed and extracted.

Syphon coffee maker | A must-have for beginners of coffee, with the most experimental spirit!

In 1840 , the Englishman Napier used a glass test tube used in chemical experiments to start the invention of the siphon pot. The vacuum coffee machine, which uses the pressure principle of water vapor to drive the flow of water, is a very popular coffee brewing method in Japan.

The siphon pot is constructed with an upper and lower pot connected by a tube in the middle. The lower pot filled with hot water will first be heated by an alcohol lamp or a gas lamp. Because under an atmosphere of 1, the volume ratio of 1 gram of liquid water to 1 gram of water vapor is 1:100, when the volume of water vapor in the lower pot increases with the temperature, the liquid water can be easily pushed through the tube to the upper pot equipped with filter cloth and coffee powder, and the water will continue to be supported in the upper pot by an endless supply of water vapor.

When the heating is stopped, the air in the lower pot will gradually cool down and shrink, and the coffee liquid in the upper pot that has been soaked in hot water will flow back to the lower pot due to the loss of the support of the water vapor in the lower pot. The coffee grounds are blocked by the filter cloth and remain in the upper pot. Finally, the upper pot can be removed and the coffee in the lower pot can be enjoyed.

Siphon coffee features

Rich taste: Combining the richness of Italian coffee and the distinct layers of hand-brewed coffee, it is suitable for brewing single-origin coffee.

Beautiful utensils: Brewing utensils that resemble alchemy or scientific experiments are also an alternative decoration and taste when placed indoors.

Difficult to operate: When the water temperature is too high, the coffee powder will burn and cause bitterness, long-term soaking will produce astringency, and excessive stirring will produce sourness. Therefore, the siphon pot is a tool that requires considerable experience to use properly.

Tips: Glass pots are easy to break, so pay more attention. Do not rinse with cold water directly when the pot is still hot after heating. In addition, before heating, pay attention to whether there are any water droplets on the surface of the pot, wipe it dry with a rag first to prevent it from breaking easily during heating.

Steps:

1. Pour water or hot water into the lower pot, boil it with an alcohol lamp or gas stove, and put the filter into the upper pot.

2. When the water boils, insert the upper pot into the lower pot. The water will slowly rise to the upper pot. Add coffee powder to the upper pot to soak it.

3. Turn off the heat and stir gently in a circular motion.

4. Wrap the spherical surface of the lower pot with a wet towel to cool it down, and finally let the coffee liquid drip naturally into the lower pot.

French Press Coffee Press | One pot does it all, easy to use and the easiest to get started!

In 1852 , French metalworkers and businessmen jointly obtained a patent for "filtering coffee by piston method", which created the principle of French press. By the beginning of the 20th century, it was widely known and became the most suitable tool for coffee beginners.

The filter in the French press can disperse the coffee powder in the water. When the handle is pressed down, the filter compresses the space in the device. The coarser coffee powder particles are caught by the filter and separated from the coffee liquid. The advantage of the French press is that it does not filter the coffee oil, so it can retain the essence and has a stronger aroma and flavor.

Tips: When choosing a coffee press, pay attention to the size of the filter holes and whether the distance between the filter and the cup wall is close to each other, so as to prevent coffee powder particles from running into the coffee liquid during brewing and filtering.

Steps:

1. Put the coffee powder into the pot and pour in hot water. After it sits, stir gently with a stirring spoon.

2. Cover the lid and filter and let it sit for about three minutes.

3. Press down the filter handle to push the coffee powder to the bottom of the pot, and then you can pour out the coffee liquid.

4. When pouring, leave the filter at the bottom and do not pull it out to keep the coffee powder at the bottom.

American drip coffee machine Drip Coffee Maker | The machine does the job for you, suitable for lazy people and office sharing!

The most common coffee machine is easy to operate and anyone should be able to use it. Compared with other brewing methods, the quality of the brewed coffee is poor and the taste is monotonous. With the drip brewing method, water is heated by the heating tube inside the machine and then injected into the nozzle from the top to spray on the coffee powder in a radial manner, making the coffee powder evenly moist. During the soaking, the water penetrates the coffee powder and, under the action of gravity, the liquid drips down through the coffee machine filter or filter paper.

Tips: Since the brewing machine can be used for multiple brewing, you should pay more attention to the cleanliness of the hot water outlet and coffee filter port so that the coffee can retain its original brewing flavor without being affected.

Steps:

1. Add water into the water tank.

2. Place the filter paper in the filter and add coffee powder.

3. Press the brewing switch and drip into the glass pot to complete the brewing.

Moka Pot | Commonly found in professional coffee shops and widely used in Italian families!

It was invented by Italian Alfanso Bialetti in 1933. It uses the heating method of the base to brew coffee. It is a type of distillation coffee machine. It is the most popular type of Italian coffee machine and is widely used in Italian families.

The distillation effect is achieved by using the pressure generated when water boils. The water in the lower pot turns into steam after heating and generates pressure, which is about 2 to 3 atmospheres. The pressure pushes the hot water to the upper pot. After passing through the filter of the upper pot, the pressure breaks through the pressure valve. At this time, the emulsified part of the non-water-soluble oil also extracts the coffee liquid, and the pressure breaks through the pressure valve to make the pot produce a sound. This coffee pot has a simple design and can make good coffee, so it is widely popular among the general public.

Moka Pot Features

Strength: Between espresso and siphon coffee.

Easy to carry: A must-have for people who like to go hiking and swimming, it is durable and can brew good quality coffee. It is great to have a cup of good coffee with you in the beautiful scenery of the mountains. The traces on it are the struggles it has experienced with you.

Safety: Because of the pressure, pay attention to the control of the alcohol lamp when brewing, and the water in the lower pot must not flood the pressure relief valve.

Tips: When filling the kettle with water, you need to pay special attention that the water level cannot exceed the position of the pressure relief valve. The pressure relief valve can avoid the problem of excessive pressure in the kettle, so you need to pay attention when using it.

Steps:

1. Fill the lower pot with water. The water level must not exceed the pressure relief valve on the lower pot.

2. Fill the middle filter with coffee powder and assemble the upper and lower layers of the moka pot.

3. After assembly, place it on the gas stove and heat it over medium-low heat.

4. After the water is heated, the kettle will make a buzzing sound due to the steam, and you can turn off the fire at this time.

Espresso Machine | An important invention that has transformed coffee, suitable for both commercial and home use

Espresso machines are the fastest way to extract coffee, and the equipment is also the most expensive, ranging from just over 10,000 to hundreds of thousands , which is like parking a car on a table... After the Italians applied for a patent for "steam-operated rapid coffee beverage production equipment" in 1884 , it gradually evolved into Italian espresso machines. The improvement and popularization of Italian espresso machines is an important driving force behind the global coffee trend.

It is made by pressing coffee powder with hot water at about 90 degrees Celsius and a force of about 9 atmospheres (bar). Usually a cup contains only 30 ml and has reddish-brown foamy fat (Crema) floating on the surface. It has the characteristics of fast brewing and high concentration, and needs to be cooked with a special machine.

When coffee powder comes into contact with 90 degrees Celsius hot water, it releases carbon dioxide, as well as essential substances such as oils and spices in the coffee powder. Since carbon dioxide has its own gas pressure and water has its own surface tension, and the high-pressure water of 9 atmospheres has the same gas pressure as carbon dioxide, it can allow water to envelop carbon dioxide, which is the essence of coffee beans, and form Crema.

Italian coffee equipment

Italian coffee machine: It is recommended to buy one from a large manufacturer that costs at least 10,000 yuan, as the quality is guaranteed.

Bean grinder: The choice of blade type is very important. The importance of the bean grinder is even higher than the coffee machine itself, which affects the quality of the ground coffee powder.

Milk froth steel cup: a must for making milk froth and latte art, it is recommended to choose a cup that is twice the capacity of a coffee cup

Thermometer, measuring cup, timer: Due to the extremely fast extraction speed, even the slightest difference in data will have a great impact on the flavor.

Italian coffee characteristics

The extraction speed is extremely fast: an average of 30 seconds for a cup of coffee. The steps are simple and it is easy to learn by making a set of SOPs. It has become the preferred brewing method for almost all coffee chains.

Variety: It is very common to drink espresso directly in Italy (according to statistics, Italians drink an average of 7 cups of coffee in different forms a day). In Taiwan, espresso is mostly made into latte, macchiato, cappuccino and other fancy coffees.

Expensive equipment: Compared to skills, Italian coffee requires more equipment. Unlike hand-brewed coffee, it is difficult to brew a good cup of espresso with a coffee machine with a poor boiler and pump.

Unable to show the characteristics of coffee beans: Italian coffee emphasizes fast extraction, which to some extent destroys the original uniqueness of coffee. Most stores choose to make blended coffee beans using their own methods to show the characteristics of their own Italian coffee.

Tips: The warm-up time before the machine is extracted is quite long, so please pay attention. When filling the coffee powder, avoid the coffee from being exposed to air for too long to lose its freshness. When filling the coffee powder into the filter, pay attention to the speed and time. When maintaining the machine, pay special attention to the cleanliness of the equipment.

1. Put the ground coffee powder into the filter and smooth it out. Use a tamper to tap the filter so that the powder is evenly distributed in the filter.

2. Take the tamper and use your palm to press the coffee powder. After pressing, press it again and use more force to make it smoother.

3. Place the colander onto the colander handle and lock it.

4. Turn on the switch to brew.

The knowledge of coffee is extensive and profound, even more complex than red wine. Different bean varieties, origins, estates, coffee bean processing, roasting methods, and brewing methods have evolved into tens of thousands of different coffee flavor variations. But in fact, as long as you buy a cup of coffee you have never tasted before every day and try it repeatedly, you can slowly become a little coffee expert. Don't be greedy for temporary convenience and lose the fun of exploring in life while drinking bad coffee.
