A positive way to preserve coffee beans: "Open the package before use and use it all at once"!

Most coffee books have almost no objection to the purchase of coffee beans: "to be fresh, buy only one week's quantity, preferably from a store with large sales." these conditions are necessary, but how do you preserve the coffee beans before they come into your hands? At present, coffee roasters mainly sell to business customers, and in order to meet the needs of business customers at any time, they must hoard a large number of coffee cooked beans, and sometimes as many as dozens of packets of tens of kilograms of coffee beans should be preserved. Can you find a coffee roaster who only works in retail?

If a coffee maker cannot properly preserve the beans from roasting until they are sold, what if you find a coffee supplier that meets the above criteria?

Many large-scale manufacturers are also aware of this, so various kinds of bags, such as vacuum bags, breathable bags, nitrogen-filled packaging, and so on, are widely used in the packaging of coffee, and claim that such packaging can last for several months to one or two years. In particular, breathable bags with one-way valves even claim that there will be no oxidation. But the moment you take this kind of coffee home and unpack it, all the perfect packaging disappears as the coffee touches the air. In particular, the longer the coffee is roasted, the faster the coffee spoils. Yes, since the coffee left the roaster, she has quietly deteriorated, all the packaging is to try to maintain the quality of the packaging, so even if you carefully protect this can of coffee, her quality can not be as you like!

There are restrictions on the preservation of coffee. Whatever way you use to preserve coffee, you must pay the price, and you will get what quality of coffee!

The most positive way to preserve coffee beans is to "open the package before use and use it all at once"!

Whenever consumers ask me how to preserve coffee beans, I always suggest that they seal the coffee carefully and put it in the side door of the freezer. When brewing coffee, take out the amount needed and put the remaining coffee back immediately. This practice is to use the concept of "low temperature freezing" to slow down the oxidation of coffee, which can usually more than double the shelf life of coffee. However, in the process of taking out and taking in, it is still impossible to avoid the change of temperature, so if you can, it is best to "pack" one part of the coffee in a plastic bag, then seal it with a plastic bag sealing machine and put it in the refrigerator for cryopreservation. When you use it, only one copy will be taken out and the rest will continue to be preserved. Although this takes a lot of work, it can greatly prolong the life of the coffee, but most people are scared off by this complicated procedure! However, apart from this method, I can't think of any other way to properly preserve the original flavor of coffee.

The manufacturer that uses this idea most thoroughly is Nestl é. Nestl é Coffee has a domestic Italian coffee machine called nespresso. A cup of coffee powder is hidden in an exquisite and dazzling aluminum container "aluminum bag". The colorful "aluminum bag" is cute and a bit adorable. When brewing coffee, put the "aluminum bag" into the handle, put it into the machine, press the switch, and a cup of fragrant coffee comes out quickly. I am not advertising for Nestle, but this "aluminum bag" completely explains under what conditions it makes sense to talk about the preservation of coffee!

At first, when I saw this "aluminum alloy", I only thought that the packaging design was very dazzling and it was easy to draw people's attention to its appearance. Later, after careful consideration, I found that this approach was really not simple. Other manufacturers who use this concept either use paper packaging and plastic bags (such as "illy" coffee) or use "glue" (such as "Lavazza" coffee). Only Nestl é coffee uses "aluminum", which uses very expensive production technology. in addition to the high cost of the whole set of production equipment, "aluminum molding" plus vacuum packaging technology needs to overcome many difficulties. If it were not for this kind of big manufacturers in the world, they would not dare to adopt it (I do not know whether it is in line with the concept of environmental protection), and in my memory, Nestle coffee is instant coffee, and apart from this "aluminum cake", it does not produce grinding coffee, so I think Nestle Coffee must have tried various packaging methods and adopted such expensive packaging when it launched this "aluminum cake".

The advantage of this kind of packaging is that the coffee is vacuum sealed in "aluminum". As long as it is not opened and the preservation effect is almost semi-permanent, it completely shows the positive practice of coffee preservation, and its only disadvantage may be the high price brought about by "sub-packaging". And the use of "aluminum" must be made with a special machine, which greatly increases the cost of drinking coffee, coupled with the fact that the taste of Italian coffee is not acceptable to everyone, and limited by the taste it provides, it is unable to enjoy the pleasure of cooking individual coffee.

Therefore, what kind of way to preserve coffee, you must pay what price, you will get what quality of coffee! If you really ask for the quality of coffee, I can only ask you to "pack" the coffee yourself, or choose the coffee packaging with the concept of "sub-packing"! In all other ways, he is better than nothing!
