Six common mistakes that beginners should avoid when making coffee the correct way to make coffee

No one wants to spoil their own coffee, especially boutique coffee beans that are not cheap. No one wants to drink a bad cup of coffee, but these common mistakes, as long as you bet on one of them, no matter what you use is not just a waste of a pot of coffee, if you still don't realize what the problem is, you will make mistakes again. Are your coffee beans fresh and fine?

Even many professional baristas forget to pay attention to the date of coffee beans when making coffee. If you can't guarantee that you're using fresh coffee beans, it's no surprise that your coffee tastes bad.

Did you use your water correctly?

On the one hand, the water temperature will affect the extraction of coffee. The water temperature is too high, it is easy to wash out the bitter and astringent taste; the water temperature is too low, the coffee taste is light, and the acidity is out of balance.

But the normal range of cooking water temperature is 85-95 ℃. Generally, it depends on the degree of baking and freshness of beans to determine the temperature of cooking water. Also pay attention to the proportion of hand-made coffee.

My personal suggestion is to divide the beans into five grades: very deep-medium-deep-medium-shallow-shallow, corresponding to 85-87-90-92-95 ℃ respectively; when the exhaust is exuberant, the steaming time is prolonged, and if the exhaust is not exuberant, the water temperature is reduced by 1-2 ℃.

On the other hand, the amount of minerals in the water will affect the taste and aroma of coffee, as well as the smoothness of the taste.

Whether the specific water is suitable or not, we need to analyze the specific situation. Anyway, the consensus in the industry is that the water quality of coffee brewing needs to be moderate, not too soft (TDS is too low) or too hard (TDS is too high).

Do you clean the cooking utensils regularly?

There are times when we all want to be lazy, especially when we find that one or two less cleaning doesn't significantly affect the quality of coffee.

But because you never know when you will drink a cup of coffee that smells of burning, fuel consumption and corruption, it is bound to be a nightmare for coffee lovers.

More importantly, if coffee machines, bean grinders and other complex utensils with water and oil are not clean for a long time, it is easy to corrupt and breed bacteria and endanger human health. At that time, no matter what high-quality coffee beans you use, you will inevitably have a bad stomach when you drink them.

Are you using shoddy coffee?

There are so many beans on the market, of course, it does not mean that the boutique level must be good, and the non-boutique coffee level must be bad. However, when drinking boutique coffee beans, the overall quality experience is always relatively higher, and the probability of stepping on thunder is much less.

We often say that "every penny is worth a penny", which is reasonable in most cases. However, there are many exceptions in the coffee industry, because there is also the saying that "goods for every penny, two cents for three cents, and three cents for ten cents". Therefore, some high-quality coffee beans, but the cup test score is one-point difference, the price can be several times different.

Are your coffee beans stored correctly?

Coffee beans are also a kind of fresh agricultural products, of course, can not be put casually.

Generally speaking, we don't need to think too much about how to store coffee beans, because they are usually in coffee bags or coffee cans, and there is no need to deliberately change the storage container. We just need to put it in the cupboard or in the corner.

But in some places it is best not to store them for a long time: wet kitchens, ovens, microwave ovens and other heating appliances, windows in direct sunlight, oxygen, moisture, high temperature and sunlight will accelerate the oxidation and deterioration of coffee beans.
