The difference between American coffee and Italian coffee! The efficacy and effect of ice American style! How much water does Americano add? What is the ratio?

I don't know if you have noticed that most people prefer iced American coffee in hot summer or cold winter. It is not like a latte that changes the temperature demand in winter and summer according to the change of season.

So why is iced American coffee more popular? Because this is an issue that is often discussed, Qianjie collected a lot of feedback from guests. The feedback can be summed up in two points: "iced American coffee will be sweeter and less bitter" and "taste more refreshing".

Generally speaking, the main factors that affect the taste of coffee are the selection of coffee beans and changes in extraction. On the other hand, American coffee is a drink diluted with water after the coffee extraction is completed. To sum up, the difference between iced American coffee and hot American coffee is the effect of water temperature. So Qianjie is going to make a new round of comparison to see what the difference is between American coffee at different water temperatures, and why iced American coffee is so popular.

In the extraction experiment, Qianjie will use the same coffee beans, the same extraction parameters and the same proportion to make American coffee at different temperatures. See how American coffee behaves differently at different temperatures! Because the existence of ice will make the concentration of iced coffee different from that of other coffee, in order to reduce the difference, this experiment will use pre-refrigerated ice water to make iced American coffee. In this way, the parameters of all coffee except water temperature are the same, which is fairer in comparison.

Similarly, the coffee beans used for extraction and concentration are still made up of sunflowers in front of the street. it is a medium-and deep-roasted Italian bean with outstanding flavor and balanced flavor. Today's extraction parameters are that 38ml coffee liquid was extracted with 19.7g powder for 27 seconds. In the daily store production, in order to allow guests to drink a cup of American coffee with appropriate concentration and outstanding flavor, Qianjie usually uses the ratio of 1ROR 4.5 to make American coffee. Therefore, all the American styles in this experiment will be made in the same proportion.

In the same way, first pour the extracted espresso into the cup, then pour in different temperatures of water (hot water: 70 °C, normal temperature water: 25 °C, ice water: 6 °C), and finally stir well, you can begin to taste!

Through the tasting, the results of Qianjie are as follows: hot American style: rich aroma, we can directly smell whisky, butter cookies. And the entrance is also very mellow, when the coffee is drunk, we can obviously feel whisky, chocolate, melon, caramel and other full flavor, with a trace of sweet and sour berries, a long finish, with a sweet taste of vanilla cream. Room temperature American style: compared with hot American style, the aroma of room temperature American style is less prominent and softer. The taste of the drink is well balanced, not so bitter, and more sour. Flavor performance is still obvious whisky, butter cookie flavor, while the taste of chocolate is weaker, the sweet and sour taste of berries will be more prominent. Iced American coffee: iced American coffee is the weakest among the three groups! In terms of taste, it belongs to a very lively type, because its overall taste has moved to the direction of sour! The entrance is the aroma of whisky, sweet and sour berries, with a hint of chocolate, the palate is very silky and light.

It can be seen that although water is not directly involved in the extraction, its temperature will change the taste of the coffee we drink. This is not because ice water changes the taste of coffee, but because low temperatures affect our taste perception. Studies have shown that when the temperature of the drinks we drink is low enough, they numb the taste buds on the surface of our tongues and become less sensitive to taste. In other words, we can not be very sensitive to the taste of chilled coffee, which has the greatest impact on the bitter taste. Sour, sweet and bitter taste check and balance each other, when our bitter perception ability is reduced, it is equivalent to the improvement of sour and sweet taste in coffee, so iced American coffee is "bitter", but its bitterness is much lower than that of hot American coffee. For many friends who can't drink bitterness but want to drink coffee, the chilled American style is simply not too suitable.

Second, low temperature will also change the taste of coffee, making it smoother and refreshing, with the function of cleaning the mouth. In addition, this kind of coffee also stimulates the nerve endings in our mouths, making people salivate and have more desire to drink.

Combining all the above advantages, we can know why iced American coffee is so popular with so many people. Of course, Qianjie is not saying that hot American is not as good as iced American coffee. Hot American style also has the advantages of hot American style, with multiple levels, rich aroma and outstanding flavor. Everyone can make a choice according to their own preferences.

Finally.
