Let's first share the tips for choosing beans:

1. Pick light roasted beans, because coffee beans have to be roasted to dark color, usually after a long time, high temperature, the loss of substances that represent the flavor of coffee itself, more transformation.

two。 When choosing coffee beans, you should choose those who are intact, dry and naturally emit bean fragrance, so as to avoid fuel-consuming, deformed and moldy coffee beans, even if the coffee beans show only a little bit of imperceptible mildew or fishy smell, it is not fresh enough.

3. Buy a small amount, one to two weeks at a time, because coffee beans only need 26 ℃ and 18.5% humidity, it is easy to produce ochratoxin, which may cause urinary tract problems and hepatotoxicity.

4. Before you buy, know the flavor of the coffee beans, so that you can understand why the same coffee beans bought in different places taste different.

5. Fresh coffee beans will smell sweet and rich in the original aroma of coffee, while those that are not fresh or over-oxidized will be poor or basically tasteless, and some will have pungent chemical smell, mildew smell, earthy smell and iodine smell and even fermented taste.

If the beans are not found to be overfermented or soot contaminated at this time, the flavor of the coffee will be affected, as these flavors may become imperceptible after roasting.

Kitchen paper towels + aluminum foil + fresh box, refrigerator can also keep coffee beans

Many people are afraid that the coffee beans in the refrigerator will be damp and affect the flavor, and they are also worried that there are other foods in the refrigerator, which will lead to the "mixed flavor" of coffee. At this time, just take a piece of kitchen paper towel, put the coffee beans that will be used for a day, add a piece of aluminum foil paper and roll it up, squeeze out the excess air, put the whole package into a flat shape and put it in a sealed fresh-keeping box, one box is exactly 1 week, the paper towel is used to adjust the moisture, and the aluminum foil can be protected from light. The sealed box is not afraid of other flavor, and it is convenient and fresh to use each time.

1. What kind of coffee utensils are used to make coffee?

If you want to make a good cup of coffee, in addition to the conditions of the coffee beans themselves, it is also important to use good coffee utensils. To make coffee, first of all, you have to have a coffee machine, or coffee pot, and you'd better tell the clerk what kind of coffee brewing method you use, so that the clerk can recommend suitable coffee beans for you. In addition, you may also be able to share your experience with the clerk.

two。 I like the taste of coffee.

Describe to the clerk what kind of coffee you like. There is no need to be as professional and relaxed as a professional coffee review, such as something stronger or sour, so that the clerk can recommend the most suitable coffee to you according to the taste characteristics of your own coffee.

3. Know the flavor of coffee beans before you buy them.

Before you buy, know the flavor of the coffee beans, so that you can understand why the same coffee beans bought in different places taste different. In addition, fresh coffee beans will smell sweet and rich in the original aroma of coffee, while stale or over-oxidized coffee beans will have poor or almost tasteless aroma, and serious ones will have pungent chemical smell, mildew smell, earthy smell and iodine smell and even fermented taste.

If the beans are not found to be overfermented or soot contaminated at this time, the flavor of the coffee will be affected, as these flavors may become imperceptible after roasting.

4. Learn to ask the roasting date of coffee beans.

As a food, coffee beans naturally have indicators such as "shelf life". Coffee beans are similar to seafood, the fresher the better.

The indicator of freshness is the "baking date". It is recommended to buy coffee beans with a roasting date of less than two weeks. Because different coffee beans, different roasting degree will affect the drinking period.

5. Learn to understand "oily" beans.

a. Fresh deep baked beans

With the deepening of roasting, more carbon dioxide will be produced, and when coffee beans reach deep roasting, they will be highly dehydrated and produce oil. Generally speaking, there is a large amount of "oil" on the surface from the first day to the second day after the baking is finished. at this time, the aroma and flavor of the deep-roasted coffee beans also reach the peak, but if the deep-baked beans are dry without oil, you need to pay special attention. Maybe you'll make a cup of "fake" coffee!

b. Stale shallow baked beans

The appearance of the lightly roasted coffee beans is dry, but dotted oil droplets will appear on the surface of the beans about 5-7 days after baking, which may be caused by uneven heating and local dehydration. This "spot oil" does not mean that it is not fresh, but it is the best taste period, but if the shallow roasted beans will be shiny after a few weeks, the aroma is very weak. With a hint of greasy taste, it means that the flavor of coffee beans has been lost and should be avoided.

6. Buy coffee and whole beans.

Basically, stores will provide free coffee grinding service, that is, they can help guests grind coffee beans into coffee powder for free. If you want to fully enjoy the aroma of a cup of coffee, it is recommended to buy whole coffee beans, WholeBean.
