Over Extracted

To further explain, each roasted coffee bean is approximately 28% soluble in water (by weight). In other words, coffee beans can be extracted in water at a rate of 28 percent by weight. The rest is cellulose, which aids in the shaping of the bean’s vegetative structure; we can split the extraction ratios to assess the quality of a cup of coffee using this information:

If less than 18% of the available solubles in the coffee are removed during the brewing process, it is termed a failure.
