I live next to the coffee shop, buy beans regularly and cook a cup every day. But I'm not a player, and for me, catchy coffee has to be both healthy and safe.

Go to a store with a large sales volume and choose coffee beans with natural luster and non-deformed body.

I often buy beans in stores with good business, because they sell a lot, circulate quickly, and have no problems of dampness and deterioration caused by hoarding. I cultivate a good friendship with the store, and sometimes get good brewing advice. On the other hand, I usually choose light-roasted beans, because coffee beans are roasted to dark color, which usually goes through a long period of time and high temperature, which may be harmful to the body.

Picking coffee beans is like buying soybeans, coffee beans themselves contain oil, fresh beans will have natural luster, you should choose beans with complete, dry and natural fragrance, to avoid fuel-consuming, deformed and moldy coffee beans, even if the bean body has only a little imperceptible mycelium attached to it, it is not fresh enough.

Kitchen tissue + aluminum foil + fresh-keeping box, simple fresh-keeping coffee beans

After buying it home, the preservation of coffee beans is the most important thing. In particular, Taiwan has a warm and humid climate, which is exactly the weather that coffee beans don't like. As long as 26 ℃ and 18.5% humidity, coffee beans are prone to ochratoxin, which may cause urinary tract problems and hepatotoxicity.

In my opinion, the premise of talking about preservation is to "buy a small amount", which can be bought one week at a time, which can avoid food waste and facilitate preservation.

The factors you need to control are light and humidity. 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.

Need to pay special attention to, do not put the fresh box in the refrigerator outlet, if the temperature is too low, coffee beans are easy to freeze, produce excess moisture, difficult to grind.

Many people will ask, "can you drink coffee beans when they are out of date?" "I suggest that once it expires, don't drink any more, and if the coffee beans obviously smell of fuel consumption, you should throw them away immediately. I still want to appeal to the importance of buying a small amount, and it can also effectively avoid the trouble of hesitating whether to drink expired coffee beans.
