Coffee is a popular drink prepared from coffee beans. But it needs a process to make it for a drink. In these processes, there are some drawbacks to using a food processor instead of a blender. However, can you grind coffee beans in a food processor? In this article, I’ll share why I don’t grind coffee beans with a Food Processor.

Coffee Beans

According to history, Ethiopia discovered the coffee plant. Also, the first cultivation was in India. There are different types of coffee beans. However, the coffee sector depends mostly on varieties that commence with two categories.

  1. Arabica Coffee
  2. Robusta Coffee

Arabica coffee is famous for its delicate flavor and low acidity. However, it is available in most coffee shops. Thus, you can keep going with Arabica beans for an easy-drinking daily brew. All detailed information is also labeled on the coffee packaging.

Robusta coffee beans are grown in harsher climates. To clarify, Robusta coffee is more economical to harvest where the water level is lower. However, different data sources said Robusta coffee beans have a more acidic and bitter flavor than Arabica coffee.

How to Grind Coffee Beans with a Blender?

Grind Coffee Beans with a Blender

The average kitchen blender doesn’t crush the beans with adjustable precision as the best coffee grinder does. Besides, the coffee grinder tries to grind the coffee beans into pieces of the same size. However, it is relatively sharp particle-like for Arabica coffee or excellent substances. These machines also aim for all of the particles in the grind to be approximately the same size. So, the main risk is lousy coffee.

Chemically, while the hot water hits the coffee, they all react the same. However, if the particles are large, and some are small in the same mixture, the coffee will have been in contact with the water too long. After that, the coffee will taste sour and over-extracted compared to the other particles. It also can be treated as flat and bland, or a little of both.

However, if you are very busy with your stuff, purchase a grinder to ease your duty. You can also quickly grind some coffee beans for yourself every day. Please remember that if you don’t have enough space to work on, don’t try at home.

A strong Blender makes your coffee grinding task easier. Just follow the simple steps-

  • Firstly, set the blender medium-high volume
  • Pour the coffee into the blender
  • Then, Shut the lid and also ensure it’s in the right place
  • Set the pulse up to 3 to 5 seconds max.
  • Finally, repeat this procedure up to 6 times maximum. And in total, 30 seconds.

Bonus Methods of Grinding Beans

Mortar and pestle:

Mortar and pestle

No strange, but an artisanal way of coffee grinding. I think it is the most old-fashioned way to do that job. To clarify, add your coffee beans to your mortar and crushing them properly to get the output. After that, these grinding beans provide the perfect espresso grind.

However, if you’re not used to manually crushing things, you may face some problems. You have to apply the right amount of pressure. So, you can get a uniform grind as you proceed. First, try it slowly and add as a small number of beans as you can.


Typically, it sounds like crazy! If you don’t get a mortar and pestle. After that, put your coffee beans in a bag and sandwich the bag with some parchment. Use the hammer as if you were like tenderizing meat. However, there should be enough power with each punch. But don’t exhaust it as you are crushing coffee beans.

Rolling Pin:

You can grind your coffee beans using a rolling pin quickly. However, this method will work best for French press coffee, as the grounds are finer than those used for drip coffee. It’s also a bit laborious, but you’ll get the result you need in a pinch.

Besides, using a wooden dowel or rolling pin, you end up with a medium-to-fine grind. It is ideal for drip coffee brewing or pouring coffee.


This method requires more gentle precision, partly for its art and partly because it can be dangerous if not done carefully. Although one would assume that this method requires cutting, it is not. To clarify, using your palm, press the beans firmly onto the blade. Also, keep pushing to grind and pull the blade slightly toward you so that your grind becomes finer.

Why Shouldn’t I Grind Coffee Beans with a Food Processor?

Can you grind coffee beans in a food processor? A proper grinder or blender gives you evenly sized particles. On the other hand, a food processor or a blade grinder delivers a wide range of sizes. That is not a good solution to make a perfect coffee.

Besides, coffee extraction is highly dependent on the size of the particles. A wide range of different sizes produces coffee that can’t make good quality coffee. So, the smell or flavor is not good if the chopped or smashed beans are not uniform.

Moreover, you cannot grind just a cup worth of coffee beans in a food processor. In other words, if you grind more coffee, you can make it right away. Coffee beans should be grounded just before brewing them.

Precisely due to particles size, the food processor is not the solution for coffee grinding. So, I should not recommend grinding or scraping coffee beans using a food processor. For output (coffee), the ground pieces must have to be uniform and not hot.

A food processor also uses sharp blades to cut through the coffee beans. These blades will smash the beans, giving you a somewhat coarser grind. Besides, the grounds won’t give such uniform output as a coffee grinder offers.
