Although these tips are widely used and can solve the problems found in various cooking methods, the necessary conditions for them to be established are high-quality cooking water at the right temperature and coffee powder of good quality and uniform grinding. A skilful wife cannot make bricks without rice. Please pay attention to the quality of raw materials.

Symptom 1: acid

Insufficient extraction of coffee will taste sour, there is not enough time to extract, the coffee will lead to light taste, and only sour taste. If the coffee beans you are drinking have "natural sweetness, fullness and round taste", but you only drink empty and sour, there is no other flavor, then you can be sure that the extraction is incomplete.

Solution: adjust the grinding or time to allow more coffee flavor to be dissolved and extracted into your cup. You can try to extend the extraction time or fine-tune the grinding scale. The thickness of coffee powder determines the extraction time of coffee, so the coarsely ground coffee powder needs to increase the extraction time than the finely ground coffee powder. Grind your coffee powder a little bit and try it again.

Symptom 2: bitterness

Is the coffee bitter? Maybe too much was extracted from the coffee powder.

Solution: adjust the grinding or time. Like underextracted coffee, the simplest solution is to roughen and grind. In this case, roughing and grinding will slow down the extraction process, making it easier for you to find the right balanced coffee flavor. Or try to gradually shorten the extraction time to see if your coffee is getting better.

Symptom 3: stale, insipid taste

The stale taste of coffee may be due to a variety of factors, such as insufficient extraction and low brewing temperature, but it is safest to carefully examine the following: did you grind the coffee before you make it? If not, how many days has the coffee powder been on the table? Have you ever seen its whole bean status? As the freshness of coffee beans decreases and the coffee powder is ground and exposed to the air, coffee slowly loses its subtle aroma and other important flavors. Such as alcohol thickness and acidity. If you want to store coffee for a long time, or grind the beans prematurely before brewing, it will inevitably become stale and insipid.

Solution: pay attention to grinding and storage. This is an iron rule that everyone must abide by, even if it is a cheap hand bean grinder with free delivery of dozens of yuan, it is also very practical! If you are too lazy to do it, let your lover or child do manual work. After opening a bag of fresh coffee beans, try to use it up within a month and keep it as sealed as possible in the meantime.
