Why is hot American style so bitter? What is the proportion of standard American coffee? Should American coffee be poured first or second?

"as cold as a national cellar, hot is soup medicine", "this thing is many times more bitter than life", "comparable to Cantonese-style herbal tea." The above is Qianjie's sharp comments on the hot American style collected from the Internet!

In the second half of this year, Qianjie shared an article entitled "Why is iced American coffee the most popular?" "the article. Then many friends said that compared with the hot American style, the bitterness of iced American coffee is simply not worth mentioning. And from the comments on the Internet, we can also see that, without exception, the focus of people's criticism of the hot American style is that "bitter" is even more bitter than iced American coffee. As we all know, the production of American coffee is very simple! Whether it is iced American coffee or hot American coffee, espresso is extracted and then poured into different temperatures of water according to different needs. The coffee base itself does not change, only in the water temperature. But why is hot American much more bitter than iced American coffee?

The effect of temperature is very simple, and the problem mainly lies in temperature. One of the points that Qianjie often shares is that temperature affects how our taste buds perceive taste. Our taste buds have different perceptions of different tastes at different temperatures. For example, the reason why iced American coffee is not so bitter is that the temperature of the coffee is too low, resulting in a decrease in the perception of bitterness.

On the contrary, the hot American style is sour because of its high water temperature. Then because of the checks and balances between tastes, a decrease in sour taste means that other flavors have been improved. In addition to the sour taste of coffee, the most obvious and prominent thing is bitterness, so naturally, when the temperature is higher, the coffee will feel more bitter.

The second influence of coffee beans is the problem of coffee beans! Due to the low output of espresso, or for some other reasons, many coffee shops only set up an Italian mill, and there is only one type of Italian coffee beans. In order to worry about the production of milk coffee, the choice of coffee beans needs to be further selected. On the other hand, the coffee made from medium-deep and deep-roasted coffee beans will have an obvious scorched aroma, which is very consistent with the bitter taste, and the high temperature will increase the volatilization of the aroma, which can easily lead to the illusion that the bitter taste is magnified.

The effect of excessive concentration

Another reason why hot American is more bitter than iced American coffee is the concentration of coffee. The amount of hot American cups in most coffee shops is smaller than iced American coffee, because iced American coffee needs ice to cool down. In the former street, for example, the proportion of hot American coffee in the front street was 1:4, that is, 40ml coffee liquid was then paired with 160ml hot water, while the proportion of iced American coffee was the same at 1:4, but about 90g of ice was added on this basis.

Although the ratio of coffee to water is the same, because the ice of iced American coffee melts, hot American coffee is actually more concentrated than iced American coffee. As a result, the flavor and flavor of hot American coffee will be more concentrated. Hot American coffee obviously tastes thicker than iced American coffee, which has a lower concentration and unfolds its flavor. Then add the buff provided by the previous two, and the hot American style is not as good as iced American coffee.

The advantages of hot American style, but Qianjie is not saying that hot American style is not as good as iced American coffee, just analyzing the reason in the direction of "bitterness". Hot American style is not inferior to iced American coffee, and its advantages are also very unique: because its temperature is higher, so the aroma will be more intense, and then a higher concentration can help us capture the flavor. Finally, the temperature will drop, which makes the taste and taste of the coffee constantly changing, and the level is very rich!

So, it's time for Qianjie to ask: iced American coffee or hot American style, which do you prefer? Or is it... Room temperature American style?
