Many coffee beginners have heard of raising beans, preservation needs to use one-way valve bags or one-way valve cans, it is true that after these steps will make the flavor of coffee beans better, because of various factors and coffee beans produced in different countries and estates, all let this step-raising beans/waking beans The way and time are not the same, this article will take you to understand what raising beans/waking beans are.

Carbon dioxide-breath of coffee beans

Take hand-brewed coffee as an example, and then add hot water to do steams, will release a lot of carbon dioxide, causing a feeling like coffee beans in the breath, but also many people judge whether a cup of hand-brewed coffee is "fresh enough" standard;Espresso Crema is also carbon dioxide is covered by fine foam, so fresh enough coffee beans will be brewed out when there will be a layer of beautiful Crema, then drink Espresso when you can observe how the freshness of the coffee brewed by the store, dark red Crema represents coffee is still very fresh, and golden although beautiful but not so fresh.

The fresher the coffee, the more carbon dioxide content, but if you want two or three days to go to the coffee shop to make up the goods, perhaps not practical also appears troublesome, coffee beans are very noble products, very susceptible to humidity, oxygen, light or heat temperature, the best way to preserve him is cool, dry place, and eliminate the air is the most difficult, not to mention Taiwan's air is humid.

One-way ventilation valve-prolong the preservation of coffee, a good partner for raising beans

It would be great if we could keep the air out!

Yes, a one-way breather valve achieves this effect. A coffee bean bag/can with a one-way breather valve allows the carbon dioxide released by the coffee beans to sink, which in turn allows lighter oxygen and nitrogen to be squeezed out of the bag/can. Just like cut apples will turn yellow when they touch oxygen, coffee beans will also begin to change when they touch oxygen. In order to prevent these qualitative factors, the packaging with one-way ventilation valve is the right choice, and coffee hunters are using one-way ventilation valve packaging when shipping!

Nitrogen filling-no oxygen

I have seen the potato chips in the convenience store are always strands. When I opened it, I found that only one-third of the packaging was potato chips, and the rest was filled with nitrogen. This can eliminate the contact between food and oxygen and extend the service life. Coffee beans can also be sold in Illy. Coffee beans and powder will be packed with nitrogen to extend the service life of coffee beans.

Roasting-The process of coffee beans

The roasting degree is divided into very shallow, shallow, medium, medium deep, deep and so on. According to the cultivation estate of coffee beans and the country, there will be different treatment methods, which depend on professional roasters and experience. There are also different practices in direct fire, semi-direct fire or hot air type. The topic of roasting beans is too big. The discussion may take up the whole space, and the introduction will be made later.

bean growing time

Some coffee players began to learn, thinking that yesterday's baked beans coffee beans can be brewed and drunk immediately today to get the freshest flavor, so when brewing, they found that the taste was not as good as imagined, and even suspected whether there was a problem with their own technology. It was not until two weeks later that they found that they were getting better, but the batch of coffee beans also bottomed out. This means that there is no time for coffee beans to grow beans, but there is no way to brew the best state. This is a small mistake that many novices will make. But how do you know what a better flavor is without experiencing mistakes and trying?

Coffee beans are like living personnel, people with oxygen inhalation caused by cell oxidation, but also the process of aging, just roasted coffee is too young, did not reach the most mature stage, like people, after years of growth will create a more mature you, need to give coffee beans some time.

Why did this happen? Because the roasted coffee beans, flavor composition has been roughly determined, many people blame the coffee beans on the daily changes, but as mentioned above, everything will be slightly deteriorated after oxidation, affecting the taste, may not be so fine taste on apples, but coffee will obviously feel the taste change. The freshly roasted coffee beans will release a large amount of aroma factors and carbon dioxide, which will be released through small holes in the roasted coffee beans. When grinding, these carbon dioxide will run out. However, in the process of brewing, the contact between powder and water will be eliminated, resulting in insufficient flavor extraction. As the gas layer of carbon dioxide becomes thinner and the contact area increases, the coffee will become more and more delicious. Therefore, many people do not call raising beans, but a deflation. The process of exhaust.

The best tasting period has passed

You have a question: if I put all the carbon dioxide out, wouldn't it smell good?

Don't forget, with time, aroma factor is also constantly losing, and so you put it at that time brewed coffee may only have bitter taste, some of the sour and sweet have been released by you, according to the degree of roasting or store recommendations to raise beans is a better choice, in addition, it is also recommended that the process of raising beans can be shaken to let the coffee beans below can also be ventilated to the top.

As soon as the beans were roasted, he counted down his tasting period, which was about two weeks after the beans were grown. In the best taste period, it is possible to cause coffee beans out of the oil situation, in fact, is normal, but also a small warning, that is, the flavor of coffee beans has to accelerate the decline, remind you to hurry to finish brewing, will not waste the delicious coffee beans yo!

How long does it take to grow beans? -How do you distinguish them according to the degree of roasting?

There is no specific timetable for growing beans, only experience or advice from the baker.

The recommended time to grow beans is 14 days for very light baking; 10 days for light baking; 7 days for medium baking; 4 to 5 days for medium baking; and the recommended time for ordinary beans is as above. Because on the hand-brewed coffee, it can wake up the coffee enough when steaming, if it is Espresso Italian beans, the general bean cultivation time is 21 days, but the coffee beans for business use do not have so much time to grow, so it will accelerate the awakening of beans in contact with the air, so that the coffee beans can reach the smooth phase, if brewed too early, it may cause the situation of not smooth mouth and throat.

conclusion

Waking beans is a necessary process, coffee beans knowledge is very much, to drink a cup of good coffee is not simple, grasp the roasted beans, equipment purchase and the most important grinding beans, you can brew a cup of good coffee at home.
