Analysis of the key factors of coffee bean aroma and grinding!

For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)

Have coffee drinkers noticed that a smell of coffee comes out of the grinder when the beans are ground into powder? Or is it the smell of coffee squeezed from fresh coffee beans packed with coffee exhaust valve bags?

In fact, fresh coffee beans can breathe. Through the pores on the surface of coffee beans, bursts of coffee aroma are volatilized out. The aroma of the whole coffee bean can be preserved for 7 days under normal conditions and then slowly weakened. But when coffee beans are ground into coffee powder, they may only have a coffee smell of 3 to 4 minutes, because the area of coffee powder oxidized is larger than that of coffee beans. This is also the reason for grinding coffee beans when drinking coffee, of course, the aroma is only a small part.

The first good coffee is the strength of aroma, the second is the maintenance of freshness, and the third is the taste, so friends who like to drink coffee will suggest grinding coffee beans when drinking coffee, because only in this way can you really drink a cup of good coffee with pure and changeable flavor, of course, coffee beans should be fresh enough, and don't ask people to grind coffee beans into powder for fear of trouble. Because a good cup of coffee is worth your trouble.
