There are generally several ways of coffee extraction.

Use filter paper in drip coffee

The use of hanging ear coffee bags in drip coffee

Filter with flannel cloth in drip coffee

In dripping coffee, some need to use filter paper, some directly use the filter screen attached to the machine.

The French filter pot mode is an advanced version of the Turkish coffee maker.

Turkish coffee is to directly soak the coffee powder in water or to filter the coffee grounds by precipitation, drinking only the coffee liquid at the top. Some Turkish coffee pots have a faucet near the bottom (keeping the height higher than the sediment). You can turn the faucet to pick up the coffee to drink, but you have a better chance to drink coffee grounds, plus the coffee soaked for too long will produce a more bitter taste. Therefore, the design of the French filter kettle is designed to press the coffee grounds to the bottom through the filter cloth, so that coffee without coffee grounds can be poured out, and the soaking time can be considered flexibly.

Siphon coffee pot also belongs to the mode of filter pot.

Through the siphon principle, the coffee powder is soaked in boiling hot water, and the cooking time is related to the strong flavor of the coffee. The brewed coffee liquid passes through the suction tube of the filter cloth and filters the coffee grounds to make a perfect cup of coffee.

Then there is the use of machinery in the process of brewing coffee to increase the pressure on coffee powder or a small amount of hot water to soak coffee powder at a low speed to extract espresso with high concentration of coffee liquid. Espresso is usually extracted with more oil, so coffee oil and hot water pressure form emulsified viscous foam, which is called Crema (foam). The coffee is rich in flavor and almost chocolate in color. Usually drink a small amount, about 100-120cc.

Even if there are many ways of coffee extraction, it is suggested that coffee lovers should open their hearts to accept all coffee, because the author is convinced that everything has its own purpose and sanctity. All coffee beans contain caffeine, tannin, chlorogenic acid, oil, all kinds of polyphenols and other nutrients, the concept of whole food is to balance all nutrients of the whole ingredients as far as possible, so As far as coffee extraction is concerned, there is no healthier difference between the flavors I like, and the only thing that affects my health is the health of the beans and whether they are pure or not.
