How Does Extraction Works? - An Overview
Coffee brewing is whereby you mix water plus the coffee grounds, such that water removes the acids, oils, flavors, and all other essentials from the base.
Typically, the water sucks out these necessities from the beans. It, afterward, breaks up and dissolves all these things, hence the outcome of liquid coffee.
Things like sugars and acids are suspended and dispersed quickly than the other materials such as oils and solid particles, which take more time to disperse.
Usually, an extraction that is well-balanced contains richer flavors, good acid content, incredible taste, as well as some feel of slight bitterness to complete the whole flavor outcome.
Besides, the over-extraction aspect comes about whenever you extract outside the sweet point. This means that you extract too much from the grounds.

However, the kind of bitterness described in this content is the in-your-face bitterness, which does not intensify the strength or complexity to the other flavors. It instead, overshadows them.
Behind the bitter coffee is the extraction of a cluster of bitter chemicals from the ground. Apart from caffeine, these chemicals naturally extract after everything else pulls out.

2. Extreme agitation
Whenever you brew with a method that involves shaking, stirring, or swirling, you may over agitate. The more forceful you are with your brewing, the quicker the extraction occurs. In this case, you may non-deliberately over-extract.

Extremely fine coffee grounds causes the water to extract materials from the ground quicker than it should. It is, thus, the same as brewing extensively.

Extreme pouring of water over the grounds quickly leads to the over-extraction of coffee. For instance, if you pour beyond your intended water weight, all the additional water only pulls out the extra materials, which make your brew over-extracted. Ensure you work with the golden ratios.
