Relationship between water temperature of hand-brewed coffee and extraction tools and freshness of coffee beans

When brewing coffee, you are often asked how many degrees of water should you use to make it?

The recommended temperature range for hand punching is between 80 degrees and 90 degrees. How many degrees is that?

We actually tested the existing coffee, using water temperatures of 93 degrees Celsius, 88 degrees Celsius and 83 degrees Celsius, to brew light, medium and deep roasted coffee beans, the flavor of shallow and medium roasted coffee beans was the most obvious and complete at 88 degrees Celsius; the medium roasted coffee beans were sweet at 88 degrees Celsius; and the deep roasted coffee tasted clean and bright at 93 degrees Celsius.

Generally speaking, it is recommended that deep-roasted coffee should be brewed at a low water temperature, while shallow-roasted coffee should be brewed at a high water temperature. on the one hand, considering that the cell wall structure of shallow-roasted coffee beans is more complete than that of deep-roasted coffee, high water temperature can make shallow-roasted coffee extract more efficiently and evenly bring out pleasant substances from coffee beans. Brewing deep-roasted coffee at low water temperature can also avoid dissolving uncomfortable substances such as scorched bitterness at high temperature.

However, this experiment found that deep-roasted coffee performed best at 93 degrees, burning bitterness and roasting smoke at 88 degrees and round and soft at 83 degrees. Why is high water temperature feasible here?

After discussing with each other, colleagues infer that it may be due to the high extraction efficiency of brewed coffee at high water temperature, which relatively highlights the acidity of coffee beans, and the bright acidity and front-to-middle flavor in the absence of excessiveness. avoid the smoky and bitter taste of deep-roasted coffee.

Of course, the premise of our experiment is to use the same coffee beans and the same water quality in each cup, reducing the variable to only the difference in water temperature. if we talk about the softness and hardness of water quality and different baking methods, it is another world.

It is the mission of coffee to choose coffee beans carefully. It is our interest as coffee people to test different brewing methods. As the weekend is approaching, let's close our laptop and put down our phones, pick up handcups and coffee beans, and feel the temperature between people and coffee together.
