 How to grind coffee beans

To grind coffee quickly and easily, we recommend using an automatic grinder. You have the possibility to adjust the grind size by choosing the exact granulometry for a certain coffee maker or type of coffee. On the other hand you can grind 1/4 of coffee in a few minutes. Having a home bean grinding machine is a good idea if you are a coffee lover. However, if a grinding machine is not within your reach. You can get good results manually or with alternative machines such as a blender or processor.

Grind coffee with a blender

Easily and  in a few minutes we can grind coffee beans with a common blender. A 2.5 grain size (this indicates the grind size, we choose a generic size for an Italian coffee maker or for filter coffee) this measurement can be achieved in 2 min in a blender. Before you see the pictures. It is important to understand that a blender is intended for liquids and not for solids. Therefore we recommend that you use this method as an alternative. Don't use it as an everyday method. The blender raises more revolutions than normal. And prolonged use could damage the blender.

Demystifying ideas

The coffee DOES NOT burn and the grain size is homogeneous . What results and what quality of grinding can we achieve without a professional grinder.

Description of the grain

For this case we use a natural light toasted Brazilian Arabica bean. A good quality grain. We asked in the cafeteria to grind the beans with a professional grinder to a 2.5 measure . We brought the same coffee beans to test.

Grind grains with a Blender

Use a regular blender with 3 or 4 metal blades, with at least 2 speeds. It can be with a glass or plastic jug.

How to GRIND the grains

First we put a few grams in the blender. The minimum average is what we are going to do. Less than this amount can not. The grains should cover the metal blades at a minimum.


Process
With the jar covered and placed on the base of the motor.

1. Start at minimum speed
When we light the first time the grains jump intensely and bounce against the jug. As the seconds pass the noise begins to decrease slightly. After 30 seconds at minimum.

2. We shift to full speed
We now keep the blender at maximum speed for 30 seconds, the noise is still intense. After the 60 sec elapsed with both speeds. We turn off the jar and shake it a little, tapping gently with the hand so that the content is accommodated again. We also let the blender rest for a few moments.


3. Start at full speed
We hold for 30 seconds and then we go back to

4. Change the speed to minimum  
After doing this process you will have completed 2 minutes of grinding.


Value data
Variation of speed during processing is important. While the fast speed allows us to fine-tune the granulometry. Low speed is necessary to homogenize the cut. You can repeat this process a few more times and you will keep reducing the size. The really important thing is that you turn off after 30 seconds of low speed. This ensures that you get a homogeneous ground coffee.

At first glance, there is no difference between coffee ground by a blender or by a professional grinder.

We clear the grains and spread the coffee on the crockery to distinguish but still. The grind is homogeneous.


Difference between grain grinds

Ground coffee in two different ways

Clearly a blender is very similar to many metal screw grinders. That is why such good results. Conclusion the method achieves very good results. Therefore, if you are tempted to buy coffee beans and you don't have a grinder, you can use this method perfectly. We do not recommend it for regular use. First, because a grinder is more practical and allows to have a much superior grinding control. But if it can be for a first step before investing in a coffee grinder. And thus encourage you to buy coffee beans. Drinking coffee with freshly ground coffee makes a real difference in taste and aroma. When the seed breaks, it releases its instant freshness. Like any natural product, that is why it is important that you do the experience yourself.
