The difference between Ice American Coffee and Hot American Coffee in terms of calorie and taste

Coffee has become a necessity in everyone's life, some people use it to refresh themselves, some people use it to lose weight, and more people because of a habit. Coffee contains caffeine, it does have the effect of reducing fat, but it can't be used as a weight loss, it's just a drink.

American coffee is a kind of coffee, which is not as rich as hand-brewed coffee and not as strong as espresso, which belongs to the taste between hand-brewed coffee and espresso. Some people say that American coffee is drip-filtered black coffee.

American coffee is so named because during World War II, American soldiers chose to mix espresso with hot water to get more caffeine, so they could drink twice as much coffee at once. "American coffee" (English: Americano, Italian: Caff è Americano) is a kind of coffee, and it is also the most common coffee. It can be black coffee made by using a drip-filter coffee pot, or it can be made by adding a lot of water to Italian concentrate. But the American coffee we often talk about is the latter.

Qianjie has always told everyone that coffee must be served from hot to cold, so that it can fully taste the flavor of the cup, because the flavor of coffee is different from high to cold. However, with everyone's different pursuit of coffee, there are all kinds of brewing methods. Sometimes I just want to have a cup of cold iced coffee, which is refreshing and refreshing at the same time, especially in the hot summer. In iced coffee, in addition to iced American coffee, ice brewed coffee, ice droplets, nitrogen iced coffee and other iced coffee have been seen one after another in the past few years, so is iced American coffee better or hot American coffee?

Let's take a look at the taste difference between American coffee and cold American coffee:

Hot water + Italian concentrate is called hot American, and iced American coffee with ice cubes and ice water.

Hot American style

Hot American coffee is made from black coffee made by a drip filter coffee pot, or by adding a lot of hot water to Italian concentrate. In the production of the most speed, convenient, fast, cooking more casual, simple, light taste, sweet and refreshing.

Iced American coffee

The most common iced coffee is iced American coffee (Iced Americano coffee), which is extracted by Italian coffee machine according to Italian coffee extraction standard espresso (Espresso) and poured on ice cubes and ice water, the ratio of ice to ice water can be adjusted according to personal preference. The higher the proportion of water, the lighter the coffee will be.

On the whole, there are the following differences:

1, the appearance is different: iced American coffee is lighter, while hot American coffee is almost transparent, and you can even see the brown coffee at the bottom of the cup.

2, the taste is different: the coffee of iced American coffee is not strong, the roasted coffee is smoky, and the sour taste is light. Hot American releases tannin when baking, which combines with caramel to produce a slightly bitter sweetness.

3. Different taste: ice American coffee is mellow and convergent, while hot American coffee generally has bitter, sour, sweet, fragrant and astringent taste.

There is no difference in calories between the two. They are composed of espresso and water, but one uses ice water and the other uses hot water. The calories of espresso are so low that they can be ignored. So they have nothing to do with how much hot water and ice water are added. Water has no calories, and American coffee has almost zero calories. The cold and hot of a food has nothing to do with its calories, just like we eat ice cream and melt heated ice cream liquid, but different temperatures are high in calories.

The method of making American Coffee in Front Street Coffee

The method of making American coffee is actually very simple, divided into two main steps, the first is to extract the espresso liquid, and the second is to mix the coffee liquid into the water.

Although the production of American coffee is simple, it also tests the baristas' extraction skills. A good cup of American coffee can not do without its most basic thing, that is, espresso, that is, the first major step is everything about this cup of American coffee.

If you use different beans, the flavor of American coffee will be different, so what American coffee beans do you recommend? A blend of beans used to make espresso at Qianjie stores is made of 70% Honduran sherry and 30% Ethiopian sun-tanned cherries. 70% of the Honduran Shirley is fermented in a whisky barrel, providing a strong aroma of mixed beans, while 30% of the Ethiopian sun-tanned cherries bring berry acidity to the coffee.

The part of making the base is closely related to the grinding degree, dosage, machine extraction pressure, water temperature, powder-liquid ratio and other factors of coffee powder. If the grinding degree of coffee powder is too coarse, it will easily lead to insufficient extraction and taste acidity. If it is too coarse, it is easy to over-extract and become bitter.

When extracting espresso in Qianjie, according to the capacity of the powder bowl used by Qianjie stores, it can hold 20 grams of coffee powder. The extraction pressure of Qianjie Italian coffee machine is about 9 Pa, and the water temperature is 93 degrees Celsius. 40 grams of coffee liquid was extracted.

The front street uses the Pegasus E98 espresso machine. The extraction parameters are as follows:

Pressure: 9 bar ±2

Temperature: 90.5 ~ 96 °C

Time: 20: 30 sec

Ratio of powder to water: 1. 7: 1. 1: 2.

Powder content: 12g (single espresso) 20g (double espresso)

Extraction concentration: 20ml (single part) 40ml (double part)

After making the espresso base, there is only the final step of mixing it with water. But what is the proportion of American coffee?

Traditional American coffee has an espresso-to-water ratio of 1:8, but this ratio is not suitable for all coffee beans. Qianjie Coffee has conducted a comparative experiment with 1:8 and 1:6 and found that if the espresso made from this blend of beans in Qianjie is diluted with water at 1:8, the resulting American coffee is too light in flavor and too short in rhyme. Even taste too watery. And if it is 1:6, it can highlight the taste and characteristics of American coffee made by sunflowers in front street: whisky and dark chocolate, with a good mellow finish.

Hot American coffee whisky aroma will be very active, acid quality is not obvious, more hazelnut, caramel, caffeine thickness.

The aroma of American coffee at room temperature is not as obvious as that of hot American, the acidity is soft and the taste is smooth. Because the concentrated grease layer has not been washed away, it is more like the smoothness of vanilla cream and the finish of nuts and caramel.

The aroma of iced American coffee is the least of the three, but the acidity is the most obvious of the three. On the palate, it has the aroma of whisky, sweet and sour berries and a chocolate finish of hazelnut. The palate is fresh and smooth.

People's senses have different perceptions of taste at different temperatures, so the advantage of hot coffee is that it can sense the taste change from high to low. At low temperatures, the tongue is less sensitive to bitterness and sweetness, while acidity is more sensitive. At the same time, the quinic acid in the coffee is degraded into quinine lactone, so the coffee will be more sour when it is cold. If you want to taste the aroma and aftertaste of coffee, Qianjie recommends hot American coffee. If you want to be cool, then iced American coffee is a good choice.

Suggestions for making coffee in front of the street:

To brew a good cup of coffee, you still need to pay attention to the freshness of the beans. Qianjie has always believed that the freshness of coffee beans has a great relationship with the flavor of coffee, so the coffee beans shipped in Qianjie coffee are roasted within 5 days. The purpose of Qianjie roasting is "freshly roasted coffee", so that every guest who places an order is the freshest coffee when he receives it. The bean cultivation period of coffee is about 4-7 days, so when the guest gets it, it is the time when the flavor is the best.

For those who need to be ground, Qianjie warmly reminds you that if the coffee beans are ground in advance, there is no need to raise the beans, because in the process of transportation, the pressure caused by carbon dioxide in the package can also make the coffee flavor round. so you can drink a cup of coffee as soon as you receive the coffee powder. But the coffee powder needs to be brewed in time, because the coffee powder oxidizes more quickly after contact with the air, that is to say, the flavor of the coffee will dissipate more quickly, and the flavor of the coffee is not so good. Therefore, Qianjie suggests buying whole beans, grinding and flushing now, so that we can better taste the flavor of coffee.

Whether the coffee is good or not, or which kind of brewing is good, mainly depends on the personal taste. After all, everyone's taste is different, while there are half a hundred individual coffee beans from different producing areas in Qianjie, and there are also mixed beans. Such as: Ethiopia's flower and fruit flavor coffee, Brazil peanut, nut caramel blend coffee, or Panamanian rose summer citrus flavor and so on, can fully satisfy everyone's love and discussion of coffee.
