1 use freshly ground coffee beans that are properly preserved

In order to get fresh and delicious coffee, you need to buy fresh coffee beans and grind them yourself, instead of buying ground coffee powder. The aroma of coffee lies in the subtle fusion of aromas in each coffee bean. After grinding, the interior of the coffee bean is exposed to the air, and chemical reactions occur over time, causing the coffee bean to lose some of its aroma. [1]

Make sure the coffee beans are in an airtight container. Coffee has odor-absorbing properties-which is why coffee beans are ground and can be placed in the refrigerator instead of dried soda. Unfortunately, this also means that if your coffee beans are not kept sealed in a sealed container, you may drink coffee with a strange taste.

Coffee lovers disagree on whether to store coffee beans at low temperatures. Some people suggest putting coffee beans in the refrigerator if you want to use them within a week and in the freezer if you don't use them for a few weeks. Others tend to put them in a cool place away from the light.

2 cleaning the coffee machine

Like other machines, coffee machines use a lot of hot water, and over time, coffee accumulates mineral deposits. These deposits will give the coffee a disgusting smell of decay. [3] in order to taste the best coffee, clean your coffee machine regularly. Take a look at our guide-how to clean the coffee maker

If your coffee maker has a distinct smell or deposits when it is not in use, or if you don't remember the last time you cleaned the coffee maker, it may be time to clean it.

Choose the coffee beans of the correct roughness for your way of making coffee. Different coffee brewing methods may require rough or thicker mills to get the best flavor. Because the ground coffee beans are mixed with water to change their flavor, changing the roughness of the mill (so that the whole surface is fully exposed to water) can affect its final flavor. In general, longer brewing methods require a close combination of coffee and water, as well as a rougher mill.

For the ordinary "drip" coffee machine described in the first part above, a medium mill (like what you're looking for for most ground coffee powder) is usually enough. If you use a more unusual method of cooking, such as French filtration or Ella pressure.

Use the correct temperature for your ingredients. In the process of brewing coffee, the water should be controlled at about 90.6-96.1 degrees Celsius, or slightly below the boiling point. Colder water can not extract enough aroma from coffee beans, and hotter water will destroy the structure of coffee, thus affecting the taste. [4]

If you are boiling water for coffee, let the water boil, then remove the water from the heat source and let it sit for a minute before pouring it into the coffee powder.

If you keep the coffee powder in the refrigerator, most of the brewing process will not be adversely affected by the cooled coffee beans. However, if you are making espresso, you should let the beans go back to room temperature before you can start cooking. [5] because the brewing of espresso requires close contact with coffee beans with a relatively small amount of water in a relatively short period of time, cold coffee beans will actually affect the extraction process.
