Qianjie-brief introduction of Water temperature requirements for hand-brewed Coffee

Both Italian extraction and manual extraction have their own temperature range to follow. As far as the extraction of hand-brewed coffee is concerned, an important factor that can not be ignored before the extraction water temperature is roasting. After roasting, what we call "light roasting", "moderate roasting" and "medium-deep roasting" coffee beans are obtained. however, these roasting degrees also directly affect the water temperature of coffee extraction. However, regardless of the baking degree and the water temperature, the purpose is to show the characteristics of a cup of coffee.

For the factor of water temperature, let's give an example to illustrate.

We chose moderately roasted coffee beans from Santos in Brazil, moderately ground (small Fuji), boiled by the same person at 88 ℃, 90 ℃ and 92 ℃ respectively, and finally came to the conclusion:

88 ℃ water temperature extraction, relatively speaking, felt an obvious sense of water, that is, what we call "light", and the flavor is not full enough, slightly thin.

90 ℃ water temperature extraction, taste strong nutty flavor, caramel and elegant balance, flavor performance and alcohol thickness are relatively full

92 ℃ water temperature extraction, the coffee concentration has been increased, however, the emergence of the "devil's tail"-scorched bitterness, part of the flavor is also masked.

We know that the making time of a cup of hand-made coffee is about two and a half minutes to three minutes, which is why the high water temperature is used for extraction.

Practical parameters of gouache ratio of hand-brewed coffee

[heavy flavour] 1VOG 10ml Coffee Bean weight 1ml Coffee Coffee 13.5 (Bean weight ratio unboiled Water ml)

[moderate taste] 1-12-12-1-13 (I. e. 1-14. 5-1-15. 5)

[refreshing] 1-14-1-1-1-16 (I. e., 1-14-1-1-18. 5 of the Golden Cup Criterion)

The scale is right, but the brewing proportion is not right, and it is not easy to make delicious coffee. In the process of learning, we need to drink repeatedly and test the concentration. It is found that the best brewing ratio, that is, the amount of coffee beans is higher than that of black coffee, which is between 1 cup, 12 grams and 13 milliliters, which is equivalent to the four major gold cup systems in Europe and the United States. the yield of coffee beans is 14.5 grams 115.5 per gram of raw water, and it is most likely to hit the golden range of 18% 22% and 1.15% 1.35% of the "golden cup moment". Instead of brewing espresso with tangled flavor spectrum or thin coffee with too strong water flavor.

Knowledge: the applicability of hand-brewed coffee is very strong, deep-roasted Italian beans can also be used for hand-brewing, but if you really want to drink the charm of hand-brewed coffee, it is recommended to choose high-quality beans with a cup test score of more than 80 points.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
