What makes a great cup of coffee? It’s not just one factor that goes into it, but a host of factors play a role. But when you taste a great cup of coffee, you know it.

Some people like black coffee while others prefer the regular or frothy versions. Grind size plays a role in coming up with the perfect cup of coffee. The choice varies from one person to the other. Some like their coffee powdered perfectly, while others prefer a larger grind size.

What is grind size?

Coffee beans are bigger than the ground coffee that we use for making a cup of coffee. The beans are ground for getting powdered or processed coffee. This can be directly used as a raw material for creating a great cup of coffee.

Let us consider how well coffee should be ground

With grinding, all volatile flavors and aromatics that are locked within the coffee bean are exposed. This renders a major influence over the coffee that is brewed.

Even if one puts a coffee bean in a glass of water, there will be some extraction. But it will take longer.
Now, when you chop a new coffee bean into two, it doubles the surface area. The rate of extraction correspondingly will increase, when immersed in water.

Beyond grind size, another important factor that renders an influence over the extraction is the number of particles immersed. A higher number of particles imply a greater surface area, which translates to more extraction.

A higher rate of extraction, however, is not ideal in all cases. Among all components of a coffee bean, 30% can be dissolved in water. However, the optimum extraction of the soluble solids within the coffee bean lies in the line of 18-22%. The remainder of soluble solids is not desirable for a great cup of coffee. They dissolve slower than the desirable soluble solids.

The surface area of coffee beans is directly proportional to the brewing time

By grinding the coffee finely, one raises the surface area. This stands the odds of resulting in over-extraction.

Therefore, finely ground coffee need not be brewed for a long time, while larger coffee bean particles may need to be brewed for longer for the perfect cup of coffee. This is because larger coffee particles take longer to release the flavors while the smaller particles do so quicker.

Another important factor that defines a perfect cup of coffee is the uniformity in grind size.

Uniformity in grind size

A consistent grind delivers the best result for a consumer’s coffee experience. It helps avoid circumstances wherein finer particles are difficult to sieve, while the larger ones under-extract.

Going for the right grinder

The right sort of coffee grinder is primed to deliver the best results for grinding the coffee. Maintaining the coffee grinder well also makes a difference. It minimizes the odds of rancid flavors influencing the coffee cups that you deliver.

Conclusion

In your pursuit for the perfect cup of coffee, freshly ground coffee beans deliver the best results. Buying the right coffee grinder machine is hence a worthy investment.
