When it comes to American coffee, we all know that the common practice of American coffee in cafes is espresso mixed with water, but the source of this practice is Italy, and the real American coffee is made by American coffee machine. therefore, the American coffee machine is also called the drip filter coffee machine, and the coffee powder used is thicker than the Italian coffee machine. Then in the next article, Qianjie Coffee comes to popularize why coarse ground coffee beans are suitable for drip-filter coffee machines.

Why is coarse ground coffee powder suitable for drip filter coffee machine?

American coffee is called "Americano" in English, which usually refers to black coffee made by trickling filter pot, or coffee drink made by espresso mixed with water, but now American coffee in most cafes in China is the latter, while the former is more inclined to use "drip filter coffee" to distinguish it.

And according to Qianjie Coffee, if you use a drip filter, that is, an American coffee machine, it is not easy to extract with rough grinding, because the hot water outlet of the American coffee machine is like a shower, spraying water on the coffee powder, and the water temperature of the coffee powder of the American coffee machine will be on the high side, and it will be easy to extract if the grinding degree is fine.

This is one of the reasons why coarse ground coffee powder is suitable for drip coffee. When the espresso mechanism is used as espresso, it must be filled with coffee powder to make it resistant to high-pressure hot water in order to really extract the essence of coffee. Therefore, it is more sensitive to the degree of grinding, the more uniform grinding, the more compact the coffee powder, and less space, can produce balanced resistance to water, so that a cup of Espresso can be extracted successfully. So the coffee to be used has a very fine grinding degree.

What kind of beans are used to make American coffee?

In the case of American drip coffee, the coffee beans and hand-brewed coffee hospitals both use single-product coffee beans from a single producing area, but according to most cafes at present, Italian coffee beans are used to make espresso as the base of American coffee, and a feature of espresso machine in extracting espresso is that it amplifies the flavor of coffee beans under high pressure.

Therefore, single-product coffee beans are not suitable for Italian coffee machines, otherwise it is easy to enlarge its flavor and produce a bad flavor, but using coffee beans from multiple producing areas, generally two or three kinds of coffee beans will be more common. The purpose of blending is also very obvious, is to gather the flavor of different coffee beans together, showing a new flavor, in order to achieve a more balanced effect, but also as a sign of the store.

For example, the home-made sunflower sunflower series used in Qianjie coffee shop is currently the most proud blend of coffee in Qianjie. It is made of Honduran Shirley Coffee and Yega Shirley Red Cherry Coffee. It has a rich chocolate, caramel and slightly tipsy flavor. Next, Qianjie Coffee will tell you how to make ice American coffee.

How to make American coffee?

As mentioned above in Qianjie Coffee, the practice of American coffee is to add an espresso to a cup of water. Naturally, what you need to pay attention to is the gouache ratio of American coffee. How much is the amount of water? how much is the amount of espresso made from coffee powder? In addition, the proportion of American coffee powder in each coffee shop is different, so Qianjie Coffee will explain to you with its own American coffee.

First of all, the proportion of traditional American coffee powder is 1:8. The proportion of double espresso (40ml) mixed with 320ml water can be adjusted according to the number of cups produced by the store, about 1:7 or 1:8, but it cannot be applied to all beans. So how does Qianjie determine the proportion of coffee beans that are suitable for making American coffee?

First extract the double espresso (or the number of servings), pour the extracted espresso into the sharing pot on the scale, add water in proportion and taste to determine the appropriate range, for example, after the extraction of 40g of coffee liquid, starting at 1:4, pour 160ml of water, then taste, then pour 20g of water (the proportion is 1ju 4.5) and taste the taste Similarly, continue to pour 20 grams of water (the proportion is 1:5) and taste, repeat this operation until the range of the appropriate proportion is determined.

Because you drink part of the coffee liquid every time you taste it, you can't accurately find the right ratio of American coffee powder to water, but find the right range by this method, and you need to remake American coffee in the right proportion. For example, in the above method, the proportion of warm sun blending to make American coffee is between 1:4 and 1:5, and then a cup of American coffee with the ratio of 1:4, one cup of 1chrome 4.5 and one cup of American coffee at 1:5 is remaded. finally, it is determined that the ratio of 1 4.5 is the most suitable proportion of warm sun blending beans as American coffee. In this ratio of coffee and water, it can highlight the warm sun blend of wine and cocoa aftertaste, but also without losing the thickness of alcohol. The hot American coffee parameter of Qianjie Coffee is 40ml's espresso: 180ml's 85 °C hot water / ice water mixture.

Qianjie concentrated extraction parameters:

Grinder: Pegasus 900N

Degree of grinding: 1.6

Pressure: 9 bar ±2

Temperature: 90.5 ~ 96 °C

Time: 20: 30 sec

Powder content: 20g (double espresso)

Extraction amount: 40ml

Extracted espresso flavor: smooth taste, medium mellow thickness, palate with obvious acidity accompanied by a hint of berries, whisky, strong chocolate flavor.

Iced American coffee is actually made by adding ice water to espresso at 1:7. Steps for making iced American coffee in front of the street:

1. Qianjie uses the above-mentioned parameters to extract double espresso.

2. Prepare the 280ml ice-water mixture.

3. Pour the double espresso into the ice water mixture, stir well and start drinking.

Ice American coffee taste description: Qianjie coffee self-use warm sun mix in the flavor with obvious chocolate and wine aroma, the production of espresso mixed with ice water will be refreshing and smooth taste, more obvious wine flavor, long-lasting aroma, chocolate finish.
