There are quite many types of coffee brewing equipment, with different appliances having their own unique features and design philosophies. For example, there's the French press which is simple, convenient, and easy to operate; American drip coffee makers best satisfy the immediate tasting needs of office workers and families. The origins and principles behind coffee equipment inventions can be truly fascinating - espresso machines have gradually evolved since 1884 when an Italian applied for a patent for steam-operated coffee beverage equipment; siphon coffee makers look like special scientific laboratory equipment that was actually invented by a Scottish engineer. Understanding coffee equipment types and brewing principles will help you find the right coffee appliance for yourself.

Filter Coffee | Brew your own coffee, the most relaxing way to make coffee by hand!

Filter coffee makers have become popular in recent years, allowing you to easily enjoy coffee with simple equipment. The manual techniques involved in pour-over coffee, particularly how to control brewing temperature and speed, are topics that coffee enthusiasts love to discuss.

The gooseneck spout of a pour-over kettle is long and curved, allowing for a stable water flow. Filter cups are mostly conical or trapezoidal in shape, with ridges inside that help the filter paper adhere to the walls while leaving space for air generated during brewing to escape. Coffee grounds are steeped and extracted in hot water and then drip through.

Quick Tip: Brewing techniques can affect coffee flavor presentation, so the extraction time for paper filter brewing shouldn't be too long, otherwise it will cause the coffee to release excessive acidity and bitterness.

Usage Steps:

1. Fold the filter paper seam and place it on the filter cup.
2. Distribute coffee grounds evenly in the filter paper, then place it over the coffee pot.
3. First pour a small amount of hot water from the pour-over kettle into the filter cup to bloom, wait for the coffee grounds to expand, then continue brewing.
4. During brewing, pour hot water slowly while maintaining a steady flow, using a circular motion.
5. Observe the brewing state in the filter cup, allowing the coffee grounds to fully bloom and extract.

Siphon Coffee Maker | Essential for coffee beginners, the most experimental spirit!

In 1840, British inventor Napier used glass test tubes from chemical experiments to start the invention of the siphon coffee maker. Using the principle of water vapor pressure to drive water flow, this vacuum coffee maker is a very popular coffee brewing method in Japan.

When water in the lower pot is heated, it creates steam pressure that drives water up through the vacuum tube to the upper pot. When the heat source is extinguished, the glass sphere of the lower pot cools as air contracts, and water returns to the lower pot. During this回流 process, coffee liquid passes through a filter to complete extraction.

Quick Tip: Glass equipment is prone to cracking, so handle with care. When the lower pot is still hot after heating, do not rinse directly with cold water. Also, before heating, make sure to wipe any water droplets from the equipment surface with a cloth to prevent cracking during heating.

Usage Steps:

1. Pour water or hot water into the lower pot, bring to a boil with an alcohol lamp or gas stove, and install the filter in the upper pot.
2. When water boils, insert the upper pot into the lower pot - water will slowly rise to the upper pot. Add coffee grounds to the upper pot to wet them.
3. Turn off the heat and stir gently in a circular motion.
4. Wrap the lower pot sphere with a damp towel to cool it, allowing the coffee liquid to naturally drip into the lower pot.

French Press | One pot handles everything, the most convenient to operate!

In 1852, French metalworkers and merchants jointly obtained a patent for "filtering coffee with a piston method," creating the principle of the French press. By the early 20th century, it became widely known and became the most suitable equipment for coffee beginners.

The filter screen in a French press allows coffee grounds to be distributed in water. When the plunger is pressed down, the filter screen compresses the space in the vessel. Since coffee grounds are relatively coarse, they are caught by the filter screen, achieving separation from the coffee liquid. The advantage of French press is that it doesn't filter coffee oils, thus preserving the essence with richer aroma and flavor.

Quick Tip: When choosing French press equipment, pay attention to the mesh size of the filter screen and whether it fits snugly against the vessel walls to prevent coffee ground particles from getting into the coffee liquid during brewing and filtering.

Usage Steps:

1. Place coffee grounds in the pot and pour in hot water. Let it sit, then stir gently with a stirring spoon.
2. Cover with lid and filter screen, let sit for about one minute.
3. Press down the filter screen handle to push coffee grounds to the bottom of the pot, then pour out the coffee liquid.
4. When pouring, keep the filter screen at the bottom and don't pull it out to keep coffee grounds at the bottom.

Drip Coffee Maker | Machine does the work, suitable for lazy people and office sharing!

Brewing through filter drip method, water is heated through the machine's internal heating tube, then injected from above through nozzles that spray in a radial pattern over coffee grounds, ensuring even wetting. During steeping, water seeps through coffee grounds, and under gravity, the liquid drips down through the coffee machine's filter screen or paper filter.

Quick Tip: Since brewing machines can brew multiple times, pay special attention to cleaning the hot water outlet and coffee filter opening regularly to maintain the original brewing flavor without interference.

Usage Steps:

1. Add water to the water tank.
2. Place filter paper in the filter basket and add coffee grounds.
3. Press the brew switch, and brewing is complete when it drips into the glass pot.

Moka Pot | Common in professional coffee shops, popular in Italian households!

Invented in 1933 by Italian Alfonso Bialetti, it brews coffee through base heating and is a type of distillation method. It's the most affordable type of espresso machine and is widely used in Italian households.

It uses pressure generated by boiling water to achieve distillation effect. Water in the lower pot turns into steam when heated, creating pressure of about 2-3 atmospheres. This pressure pushes hot water up to the upper pot. After passing through the upper pot's filter screen, the pressure breaks through the pressure valve. At this point, emulsified non-water-soluble oils are also extracted into the coffee liquid, and the pressure breaking through the valve creates a whistling sound.

Quick Tip: When adding water to the lower pot, pay special attention that the water level doesn't exceed the pressure relief valve position. The pressure relief valve prevents excessive pressure buildup in the pot, so use with caution.

Usage Steps:

1. Add water to the lower pot compartment - water level must not exceed the pressure relief valve.
2. Load coffee grounds into the middle filter compartment, then assemble the Moka pot's upper and lower parts.
3. After assembly, place on a gas stove with medium-low heat.
4. When water heats and the pot makes a whistling sound from steam, turn off the heat to complete.

Espresso Machine | Important invention that transforms coffee, suitable for both commercial and home use

After Italians applied for a patent for "steam-operated quick coffee beverage equipment" in 1884, it gradually evolved into the espresso machine. The improvement and popularization of espresso machines have been important drivers of the global coffee trend.

Espresso machines extract coffee liquid in a short time through high pressure and high temperature. The machine has a vertical boiler that pushes hot water through the machine under pressure, using air pressure to force hot water through coffee grounds. Through high pressure, oils and colloids in coffee grounds are emulsified and dissolved, extracting coffee through pressure.

Quick Tip: The warm-up time before extraction is relatively long, so pay attention to this. When tamping coffee grounds, avoid exposing them to air for too long to maintain freshness. When tamping into the filter basket, pay attention to speed and timing. For equipment maintenance, pay special attention to cleaning.

Usage Steps:

1. Place ground coffee in the filter basket and level it. Tap the filter basket with the tamper to distribute grounds evenly.
2. Take the tamper and apply pressure with your palm to tamp the coffee grounds. After tamping once, tamp again with greater force to make it more level.
3. Place the filter basket into the portafilter and lock it in.
4. Turn on the switch to brew.
