"Why is the coffee I make at home different from yours?" Guests often ask this question. After a careful inquiry, I found that the guests do not really care about some details, such as: temperature!

In fact, the temperature has a great effect on the extraction of coffee, although it is only a few degrees, but it has already affected the taste of this cup of coffee.

To this end, Qianjie Coffee was brewed with a pot of red cherries at 89 degrees Celsius and 94 degrees Celsius respectively with normal extracted water and a higher water temperature.

The results showed that the red cherry extracted by 89 degree water had obvious taste of imported strawberries and berries, and the aroma was relatively clean and rising, while the red cherry extracted by 94 degree water had a strong aroma of fermented wine, but the end of the cherry was bitter and astringent, and the sense of tea was obvious after it was cold.

The flavor of the same kind of coffee is different at different temperatures, because the water temperature is high and the degree of extraction is high; the brewed coffee is thick and full-bodied, while the water temperature is low and the degree of extraction is low; it tends to be refreshing and elegant. Temperature has a great influence on the extraction rate of coffee, bitter and astringent coke is the flavor of the latter stage, if the coffee is bitter, scorched, astringent, etc., then it is necessary to reduce the extraction water temperature; on the other hand, if it is washed out and feels less freshwater flavor, that is, there are still a lot of flavors still left in the coffee grounds, so we can consider raising the temperature for extraction.

So the question is, how to choose the temperature of hand-brewed coffee? Qianjie Coffee suggests that when brewing light and medium-roasted beans, you can choose 89-92 degrees water according to the treatment and freshness of the beans; while when cooking deep-baked beans, it will be easier to extract because of the degree of baking, so it is recommended to use 84-88 degrees water temperature.
