How long does fresh roasted coffee take? How to grow coffee beans? How many days does the light baked bean keep?

"in about 2008, coffee shops were not as dotted as they are now, and there were only a handful of domestic coffee roasters. At that time, the international shelves of large merchants already had coffee beans of famous Italian brands such as illy and lavazza. I still remember that when I went to see the production date at that time, most of them had passed more than 2 months, and there were many half a year (of course, the shelf life of the goods was 365 days, and these brands used nitrogen filling or vacuum packaging technology).

With China's economic take-off, the coffee industry has also entered an era of barbaric growth. The growth of community boutique coffee shops and small coffee roasters has also begun to change people's coffee drinking habits. In the past, it was impossible to put freshly roasted coffee beans on the shelves of the consumer market because of the transportation time involved in the import of foreign-baked coffee beans, although manufacturers are constantly improving their fresh-keeping technology. With the emergence of a large number of small bakeries in China, they gradually changed to pursue the freshness of coffee beans. "in fact, freshly roasted coffee beans are much richer in flavor than those that have been kept for more than two months. As a result, people who pursue the flavor of coffee will slowly have requirements for the freshness of coffee beans, the fresher the better. But the problem also arises, originally because the coffee beans are not fresh enough and lead to the bad flavor, now it is because the coffee beans are too fresh and lead to the bad flavor. It turns out that after roasting, about 2% of the weight of coffee beans is carbon dioxide, and these large amounts of carbon dioxide will continue to be emitted. When the gas in the coffee beans is too exuberant, that is, the freshness is very high, it will inhibit the release of coffee flavor, it is easy to taste bad. And freshly baked coffee beans, washed out of the coffee is prone to dryness (smoke choking smell), which is also an uncomfortable feeling to drink.

(a big bubble formed by the gushing of gas) what about the coffee beans that are too fresh? In fact, the simplest way is to raise beans, in fact, do not open the package, rest for a few days, coffee beans will slowly exhaust gas over time. Usually, the dryness of the coffee will disappear after about 5-7 days from the baking date, and the aroma of the coffee will be richer as a large amount of gas is discharged.

Qianjie also takes into account the problem of raising beans when baking and shipping, because some guests are eager to enjoy the coffee beans as soon as they receive them. So Qianjie will send out coffee beans that are freshly baked in nearly 5 days, and then after 1-2 days of logistics, they will be able to drink immediately after the bean breeding period has just passed. If the roasting date of the coffee beans is too new, how to raise the beans? Many friends will unpack the coffee beans and pour them into carefully prepared sealed cans. Qianjie is not recommended to do so, because fresh coffee beans emit more gas, in airtight cans, it is very easy to make the air pressure in the can too high, increasing the risk of opening the jar. And when the internal pressure is high, it also suppresses the gas emission of coffee beans.

Qianjie believes that normal coffee packaging should be kept intact in a cool and dry place. There is an one-way exhaust valve on the coffee bag, which can adjust the internal pressure and avoid the invasion of external air.
