How to store the coffee beans bought home?
Do you usually have the impulse to buy coffee beans after drinking coffee outside? I bought a lot of utensils at home and thought I could cook them myself at home, but how to store the coffee beans when I got home? How long will the beans last? How long is the shelf life?
In today's article, Qianjie will teach you how to store coffee beans.
In fact, the consumption of coffee beans depends on how often you drink. Now you can buy a packet of coffee beans online or in a coffee shop with about 100g-500g. For example, if you use 15g coffee beans by hand at home, 100g coffee beans can be washed about 6 times, and 454g coffee beans can be washed about 30 times. How to store coffee beans if you buy too many coffee beans?
Qianjie advocates drinking during the best taste period, which refers to the 30-45 days after the coffee beans are roasted. It is not recommended to buy too many coffee beans. Although coffee beans can be stored in a suitable environment for a year, the flavor substances in their bodies can not stay so long! This is why we emphasize the shelf life as well as the taste period.
1. Put it directly in the package.
Now there are two main kinds of packaging for buying coffee beans on the Internet, bagged and canned. There are basically holes in the packaging, which is actually a valve device called "one-way exhaust valve". Like the one-way street of a car, gas can only go out in one direction, not in the other. But don't squeeze the coffee beans directly in order to smell the fragrance, which will cause the aroma to be squeezed out many times and the flavor will be weakened later.
When coffee beans are just roasted, their bodies contain a lot of carbon dioxide and emit a lot of carbon dioxide in the next few days. However, after the coffee bean comes out of the oven to cool down, we will put it in a sealed bag. If there is no one-way exhaust valve, a large amount of carbon dioxide will fill the whole bean bag. When the bean bag can no longer support the continuous emissions of the beans, it is easy to burst. This kind of packaging is suitable for small quantities and fast consumption.
two。 Buy bean cans for storage
A search on the Internet will appear a dazzling array of jars, how to choose? First of all, there must be three conditions, the first is to have good tightness, the second is to have an one-way exhaust valve, and the third is to be close to vacuum storage.
During the roasting process, the internal tissue of raw coffee beans expands and produces carbon dioxide, which is full of coffee volatile flavor compounds, and sealed cans can prevent the loss of volatile flavor compounds. It can also prevent moisture from the air from coming into contact with coffee beans and causing moisture.
In addition to preventing the beans from being easily burst when continuously emitting gas, the one-way valve can also prevent the coffee beans from being exposed to oxygen and cause oxidation. The carbon dioxide produced by the coffee beans during baking can form a protective layer and isolate the oxygen. But with the passage of time, these carbon dioxide will gradually lose.
At present, many coffee bean cans on the market can achieve a close vacuum effect through some simple operations to prevent coffee beans from being exposed to the air for a long time. The jar is also transparent and transparent, mainly to prevent the effect of light accelerating the oxidation of coffee beans. Of course, you can avoid it if you put it in some place to avoid the sun.
Qianjie, for example, uses jars that are accessible to vacuum packaging. In addition, the jar can be reused, so it is recommended to buy coffee beans for a long time.
There are also some friends who ask that there is no bean grinder at home, can it be ground into powder and then stored? After grinding into powder, the contact area between coffee particles and air becomes larger, carbon dioxide is lost faster, and coffee flavor substances will dissipate faster. When you go home and cook it, the flavor will fade, and you may not have the flavor or flavor that you tasted for the first time.
So Qianjie suggests buying a small amount of coffee powder and placing it in a cool and dry place to drink as soon as possible. It is not recommended to keep it in the refrigerator. When you take it out and use it after cooling, it will cause condensate because of room temperature, which will affect the quality and taste.
To sum up, if the small partners only buy a small amount of coffee beans, it is recommended to keep them directly in the bag, and if they buy a large amount of coffee beans, it is recommended to buy bean cans to keep them.

Why are Yemeni coffee beans so rare now?
People have heard a lot about Ethiopian coffee. Although Ethiopia was the first country in the world to discover coffee, in the 17th century, the first Yemeni coffee was exported to Europe through the ancient port of Mocha. Ethiopia, which is across the sea from Yemen, also sells coffee through the port of Mocha. The Yemeni mocha is the coffee trade of the World Office.
