As coffee continues to appear in our field of vision, more and more people are trying to drink a cup every day. Due to its refreshing effect and many benefits to our body, it has also attracted a large number of coffee lovers. So, as a coffee lover, making a cup of hand-brewed coffee is essential. So when making hand-brewed coffee, have you paid attention to the state of the coffee powder on the filter cup after brewing? Let me show you the state of coffee powder when there is too much or too little water.

When the amount of water injection is too much

Because the filter cup is in the shape of a funnel, its wall surface can also form extraction, thus expanding the area of ​​coffee extraction. When too much water is added, coffee grounds will adhere to the wall of the cup.

When the water injection amount is too small

Put coffee powder in the filter cup and fill it with water. The coffee will float on the water surface. As the water slowly drips down, the coffee floating on the water surface will stick to the wall of the filter cup together with the water. Then the coffee powder will naturally remain on the wall of the filter cup.

When water is poured into the filter cup wall, it causes the water to drip unevenly.

If you pour water too close to the filter cup, the coffee powder will hit the wall, and the fine coffee powder will easily block the pores of the filter paper, and the filter cup wall will not be able to form extraction smoothly. In this case, the coffee extract can only drip down at the bottom of the filter cup under the action of gravity, and it may form bitterness and other impurities due to the slow extraction speed.
