What are the advantages and disadvantages of drinking freshly ground coffee? How many times can freshly ground coffee be brewed?

Freshly ground coffee is made by roasting the wood fiber structure at high temperature, then crushing it to increase the contact area between hot water and coffee powder, so that more coffee aroma can be extracted, and finally using water to extract the coffee from the coffee powder. It is also the first choice for many people who like to drink coffee. Let's learn more about freshly ground coffee!

The pros and cons of drinking freshly ground coffee

Coffee contains a large amount of caffeine, which can effectively speed up the body's metabolism and keep the mind clear and quick-thinking, so coffee is a beverage with a refreshing function.

Freshly ground coffee refers to coffee that is extracted by grinding coffee beans into powder and then extracting them with corresponding tools. Compared with instant coffee, the caffeine and other nutrients in it can be retained to the maximum extent, and the effect achieved will be better.

Generally speaking, freshly ground coffee is just a beverage. Normal drinking of it is not harmful to the body. However, due to the refreshing effect of caffeine, if you drink too much, it may cause over-excitement of the body and cause various discomforts such as palpitations, stomach pain, dizziness, trembling, insomnia, etc.

How many times can freshly ground coffee be brewed?

once.

Freshly ground coffee is made by high-temperature baking to open up the wood fiber structure, then crushing it to increase the contact area between hot water and coffee powder so that more aromatic substances in the coffee can be extracted, and finally using water to extract the coffee from the coffee powder.

After going through multiple steps, most of the effective ingredients of coffee can be extracted after brewing it once, and what remains are some burnt substances and a large amount of caffeine. Excessive intake of these substances is not good for the human body, so freshly ground coffee is generally brewed only once.

How to make freshly ground coffee

Materials

15g coffee beans, 250ml water

1. Prepare 15 grams of coffee beans (the best drinking period is within 1 month after roasting)

2. Grind the coffee beans into powder (the uniformity and fineness of the grinding determine 50% of the coffee quality). If you want to use it at home, you can buy a manual grinding machine, which costs about 200-400 yuan (professional machines can cost from 3,000 to 15,000 yuan).

3. The water temperature is generally between 88-92 degrees, depending on the density of the beans (that is, the variety of beans). Today this is Kenya AA, I use 92 degrees water

4. Before adding the flour, wet the filter paper with hot water to make the filter paper fit the filter cup. At the same time, warm the pot (make the temperature of the upper and lower pots close, especially in winter).

5. Use 15-30ml of water to completely wet the coffee powder, simmer for a while, wake up the coffee beans, and let the carbon dioxide in the coffee beans be eliminated (the freshly roasted beans will swell up at this time)

6. After ten seconds or so, when the hill is no longer swollen, you can start the second water injection.

7. The coffee extraction process is completed in about 1 minute to 1 minute and 30 seconds. The water column circles from the inside to the outside and from the outside to the inside. The outer extension of the water circle does not touch the filter paper, preventing the water flow from directly penetrating through the filter paper and causing insufficient extraction of some coffee powder.

8. After there is enough water of 250ml, the excess water can be discarded directly. Different water pressures will lead to different water flow rates, which will cause over-extraction of some coffee powder.

9. A cup of freshly ground single origin coffee is ready! Paired with freshly baked cheese tarts! I feel so happy!

Tips

Water temperature is too low = insufficient extraction = coffee is acidic, water temperature is too high = over-extraction = coffee is bitter, distilled water is not suitable (no minerals in water can easily cause insufficient coffee extraction, resulting in a thin and sour taste)
