On the other hand, the charming sweetness of coffee beans is not strong enough, and you will feel that its taste is "stuffy". In the next few days, the smell of grass will slowly decrease, while the sweet smell will slowly rise. The sweet smell reached its peak on about the third day, and then slowly faded. On the whole, the personality of coffee beans will be obvious and active in the first few days, and after about a week, its personality will become docile.
