Introduction:Want to easily brew a delicious cup of black coffee at home but don’t know how to choose the right coffee machine and coffee grounds? This article will take you in-depth into the operating principles of drip coffee makers, their suitable capacity and grind size selection, and provide a detailed walkthrough of the brewing steps and parameter settings to help you make professional-grade black coffee with a home machine.

Many coffee enthusiasts at home are looking for a simple-to-use, cost-effective coffee machine, and the drip coffee maker (Drip Coffee Maker) is the ideal choice for beginners. This type of coffee machine is widely used in homes and offices, with intuitive operation and standardized processes, taking only about 5 to 8 minutes to brew a pot of coffee. Next, we’ll fully analyze how to use a drip coffee machine to brew an ideal cup of black coffee from aspects such as machine type, grind size, and usage steps.

Coffee machines are mainly divided into two categories based on brewing methods: drip and espresso. In the early post-war period, American households commonly used small drip machines, which were easy to operate and practical. Most of the Americanos offered in modern cafes, however, are made by diluting espresso with water. This beverage, adjusted to suit tastes during World War II by the U.S. military, was later jokingly called "American coffee" by Europeans. With this bit of history in mind, let’s focus on the practical use of drip coffee makers.

Common capacities for drip coffee makers are 5-cup and 12-cup models. The glass carafe and water reservoir of a 5-cup model are about 550ml to 650ml, while a 12-cup model can hold 1.2 to 1.3 liters. A “cup” is usually defined as 100 to 120 milliliters, so it’s recommended to brew at least 2 cups or more at a time for better extraction results. Understanding these basic capacity specs can help you choose the right model according to your needs.

In terms of the ratio of coffee grounds to water, for each 100 to 120 milliliters of coffee, it’s recommended to use 5 to 7 grams of coffee grounds. Most drip coffee machines come with a dedicated coffee scoop, typically about 6 grams per scoop, corresponding to the standard amount for one cup. Regardless of the origin or roast level of the beans, as long as they’re ground, they can be used. This flexibility allows you to freely try different flavored coffee beans and find the one that suits your taste best.

During the preparation stage, first grind the coffee beans into coffee grounds. If using pre-ground coffee, you can skip this step. It’s recommended to decide the amount of beans based on the number of cups you plan to brew, following the principle of “drink as much as you grind and brew.” Generally, one cup of coffee requires about 6 grams of coffee grounds, which can be accurately measured using the included scoop. Note that the coarseness of coffee grounds should be similar to that for pour over, a medium-coarse level—too fine may lead to over-extraction, too coarse may result in under-extraction.

For the actual brewing steps, first take out the glass carafe, open the filter basket, and add an appropriate amount of coffee grounds. Typically, 5 to 7 grams of grounds are used for 100 milliliters of coffee, and you can adjust according to the scoop that comes with your machine. Then close the filter basket, pour water into the water reservoir corresponding to the number of cups, for example about 100 milliliters per cup, adding water according to the scale lines on the machine or the glass carafe. This step affects the extraction concentration, so be sure to control it precisely. Finally, put the lid on the reservoir, place the carafe back, plug in the machine and start it—wait for 5 to 8 minutes until the dripping stops, and then enjoy your coffee.

The brewed coffee is hot, but if you want to make iced Americano, there are two common methods: one is to reduce the amount of water and add ice cubes to the hot coffee, though be aware the coffee may become diluted; the other is to mix concentrated espresso liquid with an equal proportion of cold water, resulting in a richer and more layered flavor. Additionally, you can adjust the flavor according to personal taste by adding an appropriate amount of sugar or fresh milk.

Regarding the grind size of coffee grounds, there is a significant difference between drip coffee machines and espresso machines. The former is suited to medium-coarse grounds, similar to the grind level used for pour over, which helps with even extraction and avoids clogging the filter. If you don’t have a grinder at home, it’s recommended to ask the shop to grind the beans for you when purchasing, and specify a “drip” or “drip coffee machine” grind level. The correct grind size is one of the key factors influencing flavor performance.

Finally, regarding the choice of coffee beans, there are no absolute restrictions—light roast, medium roast, and dark roast beans are all suitable. Light roast beans usually exhibit distinct fruit acidity and aroma, medium roasts are known for their nutty character and balanced taste, and dark roasts carry rich chocolate and caramel aftertastes. Different roast levels can bring completely different flavor experiences to your black coffee, and it’s recommended to try various ones to find the combination that best suits your taste.
