It's not difficult to have a delicious cup of coffee. But you must know how to buy and keep coffee. Improper preservation methods will affect the quality and flavor of coffee.
(1) Three factors affecting coffee beans: temperature/humidity/sunlight.
(2) The best tasting period of coffee: coffee beans around, coffee powder for a week.
(3) The shelf life of vacuum-packed coffee beans: about 24-28 months in vacuum cans. Flexible plastic film vacuum packaging 12 months. In order to minimize the physical and chemical changes of coffee, packaging is a very important knowledge. Because of the small contact area with air, the quality and flavor of coffee beans are more durable than ground coffee powder, so in order to maintain the aroma of coffee, grinding can be started when brewing coffee. If there is no closed container, ground coffee powder can be stored in a frozen (sub-zero temperature) storage box in the refrigerator.
I hope my answer is helpful to you.
Question 2: How do coffee beans need to be preserved? Improper preservation methods will affect the quality and flavor of coffee.
1. Three major factors affecting coffee beans: temperature/humidity/sunlight.
2. The best tasting period of coffee: coffee beans around, coffee powder for a week.
3. The shelf life of vacuum-packed coffee beans: about 24-28 months in vacuum cans.
Question 3: Can coffee beans be stored in the refrigerator? How can coffee beans be preserved for 7 days? Although the low temperature in the refrigerator can slow down the natural deterioration of coffee, it is a good storage place. However, there are many situations in the refrigerator that must be eliminated to effectively protect coffee beans; Otherwise, it will have the opposite effect. If you really need to use the refrigerator as a storage place, please pay attention to the following matters: the air in the refrigerator is cold and dry, which is easy to evaporate the water in the beans and lose the fragrance; In addition, there are too many odors in the refrigerator, so it is more suitable to store coffee beans in vacuum cans. When coffee beans are just taken out of the refrigerator, because the temperature of beans is too low, they will condense water vapor in the air and form small water droplets on the surface. After grinding, these water droplets will block the coffee powder, resulting in uneven brewing. Of course, it is not recommended that you store coffee beans in the freezer. If the coffee beans taken out of the refrigerator are not put back, they should be taken out 1 hour before use, and then unsealed after returning to normal temperature at room temperature; In this way, the surface of coffee beans will not condense water droplets, which will affect brewing. In addition, it is worth mentioning that the internal development of roasted coffee is still in progress. If the freshly baked beans are put in the refrigerator, the development of flavor will stop. Therefore, it is recommended that you keep freshly roasted coffee in a proper environment, and put it in the cold room of the refrigerator after completing its flavor development within 2~3 days. 7 Days Coffee Company is a professional coffee bean producer combining industry and trade &; Seller.

Question 8: How long can deep roasted coffee beans be kept? Deep-baked beans are greatly influenced by the environment and can be preserved for a long time, months and half a year. However, freshly roasted coffee beans have the best flavor period. Generally, it should be used after baking for 2-3 days, and it should be used up within 2-3 weeks as far as possible, so as to completely retain the flavor. Then the taste slowly dissipates, and the longer the time, the worse the taste.
Question 9: How to preserve coffee beans? ? Purchase and preservation of coffee beans
There are three steps: smell, see and peel. ◎ Put the coffee beans close to your nose and smell them deeply. Can you smell the aroma of coffee beans clearly? If so, the coffee beans are fresh enough. On the contrary, if the aroma is weak, or it has begun to feel greasy (similar to the smell of peanuts or nuts that will appear after a long time), it means that this coffee bean is completely stale.
No matter how the coffee beans are ground and boiled, it is impossible to make a good cup of coffee. ◎ Look at the coffee beans spread out in your hands, determine the origin and variety of coffee beans, and also determine whether the coffee beans are roasted evenly. Peel a coffee bean and try to peel it by hand. If the coffee beans are fresh enough, they should be easily separated and have a crunchy sound and feeling. If the coffee bean is not fresh, you will find that it seems to take a lot of effort to fry a bean.
Another important point to observe when peeling coffee beans is to see if the firepower is uniform during baking. If it is uniform, the skin and inner layer of beans should be the same color.
If the color of the surface layer is much darker than that of the inner layer, it means that the baking power may be too great, which will also affect the aroma and flavor of coffee beans.
Precautions for purchasing coffee beans Start purchasing coffee beans. First, choose a coffee shop with a thriving business. The freshness of baked beans is the life of coffee, so choose the warehouse where fresh coffee beans are placed. The place should be clean and free from bean oil residue, direct sunlight and high temperature around. This is also a good way to buy in the store, think you are mellow and bake at home.
When buying baked beans, refreshing beans can be designated by themselves. If you want to drink something slightly sour and bitter, you can also directly tell the clerk to choose according to your own preferences.
When consigned to the store for grinding after purchase, be sure to inform the manager of the coffee brewing equipment (such as electric coffee machine, filter, paper, siphon, etc.) used for grinding those props. ).
When buying canned coffee powder in the supermarket, choose the label (the type of beans or the tendency of taste, etc. ) according to your own preferences.
Question 10: I often fiddle with the computer's storage method of coffee, and sometimes I refresh myself with pure coffee powder. I don't drink very often. Two or three months ago, I bought a cup of coffee powder, opened the package and drank it twice. I don't like it very much. I have read some common sense, that is, let you drink it as soon as possible to avoid stale. My preservation method: cover the seal with 5 or 6 layers of food cling film, then seal it tightly with self-adhesive and put it in the refrigerator for preservation; When I took it out two days ago and drank it again, it was still very pure. It's a good idea to preserve it with a back seal.
