Check it out. Is there a hole in your coffee bag

Let's start with the glass jar. About the preservation of coffee beans many friends like to put beans in transparent glass jar, will wash the glass jar in advance, and then wipe very bright, bling~bling~! Then load into beans, put up, have a look at nothing, eye candy ~! Hang fried sky ~! You said it was done in the cafe next door, and I believe it! But they're selling feelings. You're just having a cup of coffee. Actually, it's not very good to put coffee beans in glass jars, and it can be a little messy, so let me explain. First of all, the key to preserving coffee beans is to keep them in the shade, away from light, air and moisture. The glass jar itself is transparent and cannot isolate light. There are coffee bags wholesale. Then, when the beans are put into the glass jar, there must be some extra air in it. The moisture in the air naturally leads to water, and the material on the surface and inside of the beans will be slowly oxidized and hydrolyzed. From a distance, it looks bright, but the flavor of the beans is rapidly disappearing. Another trouble is that the coffee beans themselves are greasy, which can contaminate the glass jar. If you change the beans, you don't want to change the glass jar with the beans, so you have to clean the glass jar again. The beans are usually packed in a special coffee bag. The most important thing about this bag is that it has a valve with several holes in it. After you take the beans, you seal the bag back in, and then you press the bag with your hand, and the air and water inside the bag will be pushed out through this valve, but the air and water outside will not get in, creating a kind of vacuum, and the bag itself is opaque, which keeps out the light. So, what better way can you find to keep your coffee beans than this self-contained bag? At least the glass jar is unnecessary. When it comes to putting the beans in the refrigerator, if you want to stop drinking them for a short time, you can put them in the refrigerator, but the most important thing to do is to lock the beans in a crisper like Loco Loco before throwing them in the refrigerator, which will prevent the odor. Coffee beans or ground coffee can absorb odors easily, and even if you have excess ground coffee, you can put it in the refrigerator to get rid of odors. However, you can't use a good bag of coffee beans to absorb the odors in your refrigerator, so it's important to keep them isolated.
