How fine is it to grind coffee for french press?

The finest grind ideal for the French press is like wheat for kibbeh. For the French press, coarse grinding is ideal. They are very distinct particles of coffee, looking like grains of coarse salt or oat flakes.

When you pick up the wheat by hand you will notice the size of the particles existing in a coarse grind.

Coarse grinding is generally used for methods where the coffee is in contact with water longer. For example, to prepare coffee in the French press, coarse grinding is used. Larger coffee particles need more contact time with water to extract the most they have to offer.

In the market, it is the most used in the preparation of softer and more flavored coffees, in which the contact time between powder and water reaches 3 minutes. Grinding in the appropriate granulometry for the preparation method used to extract the coffee is of great importance for a good extraction. 

The size of the ground coffee beans differs for each preparation method that can be used to extract the beverage.

What is the importance of grinding?

The importance of grinding is to provide a better extraction of compounds from the roasted coffee bean. Which grind is best will be defined by the method you want to use to prepare your coffee. Each method will require a specific grind.

The finer the grind, the greater the contact of the coffee particles with the water, as the contact surface of the beans increases. Let’s use brewed coffee as an example, in which it would be more difficult for water to pass through the finely ground coffee powder, as it will find more barriers to pass through. 

As a result, the extraction will be greater due to the contact time of the water with the extremely fine particles.

Continuing with the strained method as an example. Assume you are using a medium grind to extract, the medium grind will allow water to pass more easily between the coffee particles. The extraction therefore tends to be more balanced.

If we keep the same strained method as an example, but change the grind to a coarse grind, the coffee tends to be under-extracted. In other words, the coarse coffee particles will have less contact with the water, which will flow too quickly, resulting in under-extraction of the coffee. The tendency, in this case, is for the coffee to become thin.

Therefore, the correct granulometry is extremely important for each preparation method. 

How to grind coffee?

To grind coffee, you need a coffee grinder, a blender or a mixer. The grinding process is simple and similar in all appliances, it is necessary to grind the beans for about 2 to 5 seconds and take breaks between this time. In all, the procedure should take 1 to 2 minutes. Remember to grind small amounts at a time.

Among them, the blender is the most recommended for grinding coffee beans, both for the container and for its power and functions such as pulsating. If you use the mixer to grind, don’t forget to cover the container with your hand so that the beans don’t jump out.

If you love coffee, you’ve probably already considered buying coffee beans to have that fresh, fragrant drink available at home. Grinding the coffee on time preserves its aroma and ensures more freshness; however, not everyone has a coffee grinder at home.

You can also feel that the granulometry is correct through touch and visual comparison, grinding the coffee bean with the help of a rolling pin and an airtight bag. There is also the possibility of using a pestle and mortar.

If you opt for a rolling pin, remember that, as with electrical appliances, you need to grind the grain at intervals. First, place the beans in the airtight bag and roll the roll over it until you feel the husk has been broken. Then apply a little more pressure to ensure the grind.

If you prefer the pestle and mortar, it is necessary to grind 10 to 15 grams of grains at a time. As with a roller, you need to break the shell and then apply a little more pressure to grind efficiently. Put your hand to stop the beans from popping out.
