Why isn't a vacuum used on coffee packing?

The coffee that people often drink is made from ground coffee beans. It is one of the most popular drinks in the world, along with cocoa and tea.  Coffee trees are rubiaceae evergreen Trees, daily consumption of coffee is made from coffee beans with different kinds of cooking utensils made of, and the coffee beans is refers to the inside of the coffee tree fruit nut, then use the appropriate method baking, and the taste of a cup of coffee taste standard should not be bitter, a qualified barista when making coffee carefully for each step in operations,  The final coffee is presented to the guest with varying degrees of sweetness, acidity, fullness or cleanliness.  And we will find that there is no vacuum in the bag of coffee, why?  Let's talk about it today.

Many people have mentioned vacuum packaging, but so far, no reputable coffee company has used it. This is because coffee is very active when various flavors are mixed together after roasting. During this time, bad flavors (such as pungent, earthy, and astringent) are flushed out of the coffee's core, and of course, the aroma is taken away. However, what is left at the end is the most important. After roasting, the beans are incubated for a day or two to become clear and taste at their best.

If the beans are roasted and wrapped in a plastic vacuum bag, they are dead. Like a mummy, he can't breathe freely or get rid of bad smells. As a result, many coffee roasters have adopted bags with one-way exhaust valves, which not only keep the beans alive and give off unpleasant smells, but also prevent outside air from oxidizing the beans and making them stale. Coffee doesn't need a plastic vacuum bag, which I hope coffee lovers don't think is pretentious.

Continuous progress in every industry depends on continuous optimization of production processes by employees. This rigor is just about restoring the best of a good cup of coffee. Many lovers complain of dull bitterness and sharp acidity. The taste is flat. This is roughly related to the following. Bitter and sour are like twins. At the same time, it is the basic taste of coffee, with the corresponding aroma and body. These four basic flavors are essential to every good coffee.

So how do we choose the right bag for our coffee? Let me introduce our common coffee bags.

The first type: kraft coffee bag, this kind of coffee bag is usually made of kraft paper on the surface and aluminum inside. The combination of these two materials can not only make the packaging look better, but also has good resistance to light and moisture, which is suitable for the coffee beans just after roasting.

Second: pure aluminium coffee bag, bag material used in the coffee is AI/PA/PE, this kind of bag because most of the material is the material of aluminum, so has the best avoid light moistureproof property, at the same time there are various colors to choose from, and not only that adopts double zipper design, best to cut off the gas, very suitable for have already cultivate good coffee beans.

The third type: coffee bags with valves. Each of these coffee bags has a one-way exhaust valve. As mentioned above, the one-way exhaust valve not only keeps the coffee beans active and exhales the bad taste, but also prevents the outside air from oxidizing the coffee beans and losing freshness.

I'm sure you can see why you don't vacuum pack coffee.
