The Pursuit For The Perfect Cup Of Coffee

Grinding Coffee

In the pursuit for the perfect cup of coffee, all details of the process are equally important. For example, for espresso machines: The heating and pressure of the espresso machine, the amount of ground beans put into the filter and the pressure applied to that ground with the tamper.

Even such a detail as pre-heating the espresso cup before making your espresso makes a great difference.

Among all the other details, the process of grinding the roasted coffee beans is perhaps one of the most important aspects when making a tasteful coffee.

Grinding Espresso Beans

To get you started, here goes a bit of grinding theory. There are three important aspects of coffee grinding.


Making espresso is a balance between pressure and resistance. A finer or a more course ground makes a huge difference. A to course ground makes the water flow to easily thought the espresso bed and create thin and bitter cup of espresso. A to fine ground will make the brewing process to slow and will cause a burned-tasting cup of espresso.

And it does not stop at finding the perfect ground. Depending on what type of coffee maker you are using, a finer or more course ground may be more suitable. For espresso machines, in general, the higher pressure, the finer ground. Thus, more expensive machines (with a documented higher pressure at 9 atmosphere or more) requires a finer ground, while other less expensive machines is better of with a more course ground.

But don’t be frightened, the best and simplest way of finding the most suitable ground for your machine is simply by experimenting. If, you have your own grinder where you can tune the coarseness of the ground (recommended!), simply make a few cups with different grounds and decide for yourself!


A uniform grind is important, especially with higher pressure machines described above. In general, you should strive for a grind as uniform as possible, but the higher the pressure of the brewing process, the more important this factor gets.


Flaked grains versus torn or crushed grains are an important point. The flaked grains absorb water more quickly and completely than crushed grains, resulting in a more even brewing. Generally speaking, flaked grains are created by burr grinders, with sharp burrs, while crushed or torn grains are created with inexpensive blade grinders.
