Fresh coffee beans are best to drink when they are just out of the oven? Will freshly roasted coffee beans taste better after sitting for a few days? Friends who like red wine all know that good red wine needs to be opened an hour in advance to oxidize the red wine, which will be more conducive to the release of aroma. Although the principle is different, coffee does have a similar practice, which we call bean cultivation.

When it comes to raising beans, fresh coffee beans will have the so-called exhaust atmosphere when roasted, which means that the volume of coffee beans will expand when roasted, and the expanding space in the coffee beans contains carbon dioxide. Over time, this carbon dioxide will also break away from the coffee beans. This is why coffee beans need to be packed in a coffee bag with a so-called one-way exhaust valve, because coffee beans will be vented, and if you seal the bag, you will see the coffee bag inflated or even burst. The one-way exhaust valve can also discharge the gas and prevent the entry of moisture and oxygen.

Some people in ● say that when coffee is brewed, it can be said that the presence of rich air foam represents good coffee, or exactly fresh coffee, which can be said to be correct. Coffee is really the most exuberant when it is roasted. If the coffee exposed to moisture or contact with oxygen will accelerate the aging rate, the flavor will go bad, this is indeed an indicator of whether the coffee is good or bad.

But when the coffee powder is soaked in the water, if you leave it alone, when the coffee powder absorbs water and releases foam, it will actually block the coffee powder from contact with the water, and even affect the speed at which the coffee is released into the water. At this time, for the whole process of coffee brewing, it is necessary to stir to accelerate the rate of water absorption and release of coffee powder, which has a lot of views and practices.

What's more, the ● is boiled espresso, and the coffee bean powder with too much exhaust is even more difficult to control. The pressed powder layer will expand, high pressure and high hot water will pass through the powder layer, and the exhaust will become very unstable. The only way is to raise beans and wake up beans.

There are many theories about how to raise beans. For example, coffee beans are sealed in an aluminum foil bag with an one-way exhaust valve and kept in a constant temperature space for 8 to 24 hours. After opening the seal, you have to put it for 30 minutes to a few hours, come into contact with the air, in order to have a good flavor and moderate exhaust. In fact, different varieties of coffee roast the need for different beans and exhaust time is also different, we need to slowly understand.
