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

Introduction:

There are chain coffee shops and super fast-food coffee shops all over the street, but there are still people who specialize in slow workers who can make fine hand-brewed coffee. What's the best way to make coffee by hand? Talent said that the way of hand brewing and water temperature control should be correct, using a sharp-nosed pot, he recommends "rotation plus rotation" hand brewing coffee.

Wu Xiwen, head teacher of Landai Coffee and Tea, explains that taking 200cc's hand-made coffee as an example, three tablespoons of coffee are first prepared in a filter bag, heating the water to 95 degrees Celsius, and then turning a small fire. When flushing water, it flushes from the inside out, and in the process from the inside to the outside, it constantly revolves in a small circle clockwise, just like the earth rotates in a large circle, just like the earth revolves around the sun.

He said that after the first flush, there was a second flush at an interval of 10 seconds, but then it was changed from outside to inward, also in a circle in the way of rotation and rotation; after the second time, between the third, fourth and fifth times, there was an interval of 10 seconds each time, and they were all from the outside to the inside.

He stressed that after five brews, the temperature of the coffee is only about 60 degrees Celsius. It should be reheated to 80 to 85 degrees C, which is more fragrant and tastes better. If the weather is cold, the temperature can be increased.

He said that among hand-brewed coffee, the use of velvet filter bags is the best and has the strongest flavor, which is far better than the use of filter paper, filter cups and metal mesh. Of course, the best coffee to drink is siphon coffee, hand-brewed coffee is relatively mixed, lack of purity, and more insipid.

In addition, if the origin of coffee beans is the same, they also use the same way to make coffee or hand brew, but the result is not good. It may be that the baking process is not in place, or it may be that the coffee has been left stale for too long.

Relationship between water temperature and freshness of coffee beans

Take the low-leakage brewing method of filter paper as an example, freshly baked beans are still emitting a large amount of carbon dioxide. If you inject hot water above 90 degrees C, it will not produce general steaming, but will spray foam, making the taste of coffee worse. If freshly baked beans are boiled with filter paper dripping method, it is better to slowly extract them at a temperature below 80 degrees C.

Beans that have been roasted for more than two weeks have lost a lot of freshness, and must be extracted at high temperature. the water-locking ability of rancidity coffee beans on filter paper is getting worse, so it needs a higher water temperature to release its aroma and flavor.
