Is the quality of coffee beans more important, or is the machine more important?

What is extraction? The definition of extraction itself refers to a process of substance exchange between coffee powder and water.

Put aside what we often say, "if you don't grind evenly, you can't make coffee well." from a more macro point of view.

The taste of a cup of coffee is originally a combination of thousands of coffee granule extracts.

When the fluctuation value of grinding thickness is large, most of the particles can not reach the uniform degree we want.

As a result, under the same extraction conditions, the coarser coffee particles are more likely to be underextracted, while the finer particles are overextracted in advance.

Therefore, the larger the grinding span of coffee powder is, the more turbid and irritating smell can be tasted.

On the other hand, coffee powder with basically the same size and similar shape is used for extraction.

The taste becomes brighter and stronger, and the performance of flavor characteristics is clearer and consistent.

In Italian concentrated extraction, whether the degree of grinding is uniform or not not only affects the taste of the product, but also determines the success of Italian coffee.

If Italian production is carried out with a bean grinder with poor uniformity, it is easy to make the powder particles distributed in a certain part (or possibly more than one part) of Coffee pressed powder thicker, and the high-pressure water flow will quickly squeeze out of these thinner "vulnerabilities" of pressed powder, creating one or more channel effects so that the local coffee powder is overextracted while the surrounding part is underextracted. In this state of Italian extraction, it will only be a cup of bitter water.

When the grinding quality of a bean grinder is seriously lower than the uniformity required for making Italian style, no matter how fastidious the cloth powder is and no matter how good the powder pressing skill is, it is difficult to successfully make a qualified Italian style. Because the technology of powder distribution and powder pressing itself is based on the premise that the powder is uniform enough.
