Friends who often come to Front Street for coffee occasionally ask the barista: Is there a coffee maker at home that is convenient and easy to use, and not too expensive? The answer is actually quite straightforward—a drip coffee maker is worth considering.

The drip coffee maker is a highly popular brewing device today, and for those new to coffee, it is very friendly whether placed at home or in the office. It has a low entry threshold, is not complicated to operate, and the entire process is highly standardized, usually taking five to eight minutes to brew a full pot. After reading this, do you also feel like giving it a try? Below, Front Street will explain in detail the common types of American coffee makers, as well as the standardized operating steps and usage methods.

Coffee maker is a general term for a type of brewing device. If divided by brewing method, it mainly falls into two major camps: drip coffee makers and espresso machines. Before World War II, small drip machines were popular in American households, compact in size and easy to operate, thus widely circulated in American homes. However, the Americano sold in coffee shops today is actually mostly made with espresso machines. So, what is the difference between Americano made with the espresso method and drip coffee makers?

Americano made with an espresso machine is essentially espresso diluted with hot water. During World War II, American soldiers stationed in Europe were not accustomed to traditional Italian espresso, so they added hot water to that small cup of espresso, diluting it to deliberately mimic the taste of drip coffee makers. This way of drinking was looked down upon by Europeans, who thought only Americans would like it, so Europeans called it "Americano." Having understood this history, let's now follow Front Street to get to know the American coffee maker itself.

Models and Capacities of American Coffee Makers

Common drip coffee makers mainly come in two specifications: 5-cup and 12-cup, meaning they can brew at most 5 cups or 12 cups of coffee at a time. Generally, the glass carafe and water tank capacity of a 5-cup model range from 550ml to 650ml; the glass carafe and water tank capacity of a 12-cup model range from 1.2L to 1.3L.

Water Usage Standards for Drip Coffee Makers

The cup mentioned above is measured at 100–120ml. That is, the water required to brew one cup of coffee is between 100 and 120ml. When using an American coffee maker, it is recommended to brew at least 2 cups each time. Regarding the standard amount of grounds, typically one cup of 100–120ml coffee requires 5–7g of coffee grounds. Each American coffee maker comes with a special scoop, and one cup of coffee generally corresponds to one scoop of grounds; for how many cups you want to brew, add that many scoops. No matter which coffee beans you choose, as long as they are ground into powder, they can be used.

Standards for Combining Water and Grounds

To brew 1 cup of coffee, add 100–120ml of water. Specifically, refer to the markings in Step 2 and pour water into the water tank to the corresponding level; similarly, to brew one cup of coffee, add 1 level scoop of coffee grounds, about 6g, and you may adjust according to personal taste.

Steps for Using a Drip Coffee Maker

Step 1: Grind the coffee beans into powder. If you already have coffee grounds on hand, you can skip this step. Decide the amount to grind based on the number of cups to brew; it is recommended to grind and brew only as much as you will drink. Brewing 1 cup requires about 6g of coffee grounds; for how many cups, grind the corresponding amount of beans. Generally, an American coffee scoop is 6g, so you can use the scoop to measure one full scoop of coffee beans to grind, which exactly corresponds to one cup.

Step 2: Remove the glass carafe, open the coffee maker's filter basket, and pour the coffee grounds into the filter. Note that to brew one cup of 100ml coffee, control the amount of grounds to 5–7g. Place the ground coffee into the filter. Different coffee makers come with scoops of different specifications, commonly 5g, 6g, 7g, and 10g, so you need to determine the amount of grounds according to the machine's instructions. The coffee maker demonstrated here uses 6g of grounds as the standard.

Step 3: Close the filter basket, open the water tank lid, and pour water into the water tank. The principle for adding water is: for how many cups of coffee you brew and how many servings of grounds you put in, add the corresponding amount of water, with one serving being about 100ml. You can use the glass carafe to pour water into the water tank until the water level reaches the machine's marking line; refer to the water usage standards above for corresponding parameters. In addition, some coffee makers have markings on the glass carafe that are completely consistent with the water level markings on the body, helping you control the amount of water more accurately.

Step 4: Cover the water tank lid, close the coffee filter basket, place the glass carafe back on the warming plate, plug in the power, and press the switch.

Step 5: Wait 5–8 minutes, and a pot of coffee is ready (when no more coffee drips from above the glass carafe, it indicates brewing is complete). Then turn off the power and you can enjoy the coffee.

Step 6: Add sugar or fresh milk according to personal taste.

Coffee made with an American coffee maker is all hot. If you want to drink iced Americano, how should you make it?

There are two approaches: First, reduce the amount of water and add ice cubes directly to the brewed coffee liquid, but this will dilute the coffee overall quite a bit; second, switch to espresso liquid and mix it one-to-one into an ice-water mixture.

By this point, I believe everyone can make a satisfying cup of coffee at home. However, Front Street would also like to remind you: the grind size used for American coffee makers is completely different from that for espresso machines. So what kind of grounds should be used for American coffee makers? Front Street Coffee responsibly tells everyone that it is similar to pour-over coffee, because both belong to drip brewing, with similar principles, and the grind size does not need much adjustment. If you do not have a grinder at home, you can ask the shop to grind the coffee beans for you when purchasing them.

Which coffee beans are suitable for American coffee makers? Front Street believes that the flavor of Americano is closely related to the coffee beans chosen. Any coffee beans can be used for American coffee makers, entirely based on personal subjective preference. Broadly speaking, light-roast beans have bright fruit acidity and a prominent juicy feel; medium-roast beans are known for nutty notes and balanced smoothness; dark-roast beans are relatively more bitter, but their chocolate-like aftertaste is equally fascinating. Similarly, Americano made with an espresso machine is the same, except espresso beans almost always use dark roast. However, the distinct characteristics of the coffee beans can still be perceived. For example, a rather special espresso blend from Front Street—Warm Sun Blend—has obvious fermented aroma and a creamy chocolate texture, with very rich layers.
