Those who really love coffee will not be willing to accept the additive taste and drink sensation of canned coffee, and will also feel that Starbucks and Costa coffee are the same and too fast-food. In the free time on the weekends, making a cup of handmade coffee at home, turning the coffee beans into warm liquids with a strong aroma, and realizing the beauty of coffee is a very pleasant thing. Today, I want to talk briefly with you about those things about handmade coffee.

First talk about coffee beans

The most important factor in determining the quality of coffee is the quality of the coffee beans. Freshly roasted coffee beans must be selected. Coffee beans taste the best within two weeks after roasting. Three weeks are barely acceptable and can be thrown away in four weeks, so it is not recommended that you buy too many coffee beans at once, not more than 200g. Most of the aroma will be lost in 1 minute after the coffee beans are ground. Besides, grinding the coffee beans into powder is a very fun part of handmade coffee, so it is not recommended to buy coffee powder. Some sentimental personal coffee shops sell roasted coffee beans, and Taobao, a specialty coffee roaster, is also a good choice.

As for the type of coffee beans, it is one of the most important factors in determining the flavor of coffee. Choosing which one is entirely a personal preference and requires constant tasting to find your favorite coffee beans. Another important factor is the degree of roasting. Generally speaking, the deeper the roasting, the bitterer, the shallower the more sour, and the mellow degree of the coffee body will also vary. You still need to find the roasting degree you like through continuous tasting. .

The process of making coffee is plainly an extraction process-using water to extract caffeine and aromatic substances from coffee, and then filtering out coffee grounds, most appliances and methods are based on this principle. Grinding into powder is to increase the contact area between water and coffee beans to improve the extraction rate; the thickness and uniformity of the ground particles can also determine the flavor of the coffee, which needs to be explored continuously. There are two types of hand grinders, electric and hand grinders. The hand grinders are cheap, easy to clean, and also have the pleasure of handcrafting; the electric grinders produce more uniform powder, and the coffee taste is more pure.

Besides, appliances

The most traditional hand-coffee utensils and methods are shown in the picture above. You need a narrow-mouth pot, filter paper, and filter cup. You must constantly explore and try to grind the granularity of the powder, the way of distributing the powder, and the method of flushing. One day you will get a cup of coffee you like.

French press (French press, French press, left), I believe many people have seen it, but they are used to make tea, in fact it is a coffee pot. Put the coffee powder into the French press pot, pour hot water at about 90 degrees, raise the filter on the lid to the highest position, cover the pot, and let it stand for about 3 minutes. Press the net down and press down until you can enjoy the coffee.

If you like single-item coffee (made with a single type of coffee beans, called single-item coffee, as opposed to blending coffee, which is rich in taste with different types of coffee beans), it is recommended to try syphon coffee maker, left). It is heated by an alcohol lamp. The pressure generated when the water boils is used to pass hot water through the duct to the coffee powder, and the pressure difference caused by water vapor cooling is used to filter coffee.

The Balancing Syphon (pictured right) also uses the principle of siphon, but it is more visually enjoyable. Watching water and coffee liquid flow through the catheter due to the siphon phenomenon, you may think you are a scientist.

Electric drip coffee maker (American coffee machine). After brewing, the coffee powder is filtered through the built-in funnel and filter paper. It is very easy to use, as long as there is electricity, water and coffee powder in the house. Place the coffee powder in the filter paper of the powder tank, add water to the water tank, and after the glass jug is properly installed, turn on the power and the coffee will drip out automatically. After the coffee drips, cut off the power and drink it. It is recommended to purchase a graduated electric drip filter in the water tank, because it can accurately grasp the ratio of powder to water.

Moka pot (known as "Italian drip filter pot" in the United States), a two-layer structure, placed in the lower part of the water and boiled, will be sprayed into the pot through a mesh filter with coffee powder In the first half, the coffee made has the strength and flavor of Italian coffee espresso.

Iced coffee (Dutch Coffee) is a method of extracting coffee with cold water for a long time. A cup of coffee usually takes 8 to 10 hours to extract and has a very special flavor.

A few last words

There are three factors that affect the flavor of brewed coffee: grinding degree, water temperature, and brewing time. Correspondingly there are three rules: as the grinding degree becomes finer, the bitterness becomes stronger and the sourness becomes weaker; as the water temperature rises, the bitterness becomes stronger and the acidity becomes weaker; as the brewing time increases, the bitterness becomes stronger and the acidity becomes weaker. Keeping these three rules in mind, and constantly adjusting the three elements in practice, you can definitely make coffee that suits your taste.
