In the early days, domestic coffee culture was not as widespread as it is today, and there are only a few coffee shops in the country, not to mention coffee bean roasters. Therefore, at that time, if people wanted to make coffee at home, they could only go to the supermarket and buy nitrogen-filled or vacuum-packed coffee beans. The production date of these beans is often more than two months, although it has not passed the shelf life, but we can imagine what the taste of beans will be after two months.

Switching back to the barbaric growth of the coffee industry today, in the busy streets, boutique coffee shops want to dominate all the stores along the road, and there are more and more small private coffee roasters. This can not help but let us feel that people have been deeply infected by coffee culture. As a result, people began to pay attention to the freshness of coffee beans, no longer buy beans that are too old.

The reason is simple: freshly roasted coffee beans have a richer level of flavor. But the problem also arises: while people pursue fresh coffee beans, they also ask them not to be so fresh.

"what! is this freshly baked beans? no, no! feed it for a few days, and I'll drink it a few days later." what are the negative factors if the coffee beans are too fresh? Bad flavor: freshly baked coffee beans will contain a lot of carbon dioxide, this carbon dioxide will hinder hot water for the extraction of aromatic substances in coffee beans, when the aroma extraction is less, this cup of coffee will not have much experience! The appearance of dryness: the "dryness" here refers to the feeling of drinking. When you finish your coffee, there will be a trace of discomfort in your mouth and throat, such as stuck throat and dry negative feelings. These are the effects of the residual roasting aroma in the coffee beans, which are integrated into the coffee.

So how should we deal with it? "raising beans" is the best choice to deal with these two problems! When we receive the purchased beans, the first time is to check its baking date (that is, the date of production). If it is freshly baked, then we'd better not open the package and leave it for a few days to raise the beans, 5-7 days from the baking date (hand-made, Italian universal).

Because coffee beans will emit a large amount of gas from the body during a period of time when they are just roasted. When the emission of the gas is about the same, we will wash it again. In this way, there is not only no sense of dryness, but also easier to extract the aroma of coffee, so that the flavor of coffee will be fuller and richer!

If you are impatient and want to make a pot of fresh coffee right away, what should you do? If it is a rookie who is just getting started, Qianjie is also recommended to make a bubble in the regular way when the beans are freshly baked, and have a taste of fresh beans. If you just want to satisfy your stomach, try pre-grinding like this: the reason why the flavor of hanging-ear coffee is not outstanding is that after grinding, the coffee particles will emit a lot of gas. when you finish a series of operations, the aroma has long gone! Therefore, when you want to use fresh coffee beans to make coffee, you might as well leave it for 30 to 60 seconds after grinding, which can effectively reduce the dryness of freshly roasted coffee!

Prolong the steaming time: the main job of steaming is to discharge carbon dioxide from coffee beans, paving a better way for subsequent cooking. So, we just need to extend its steaming time by a few seconds and discharge more gas, so that we can reduce the effect of gas extraction.
