Few people realize that a blender could be an excellent instrument for breaking down your favorite coffee beans. The result may not be as good as a coffee grinder, but when you only have a blender to work with this is a lifesaver. Here is a step-by-step guide on how to grind coffee beans with a blender.

If you want the short version, you will need at least 3 cups of coffee beans. Because of the blade height, it’s better to use as many beans as possible to submerge the blade completely. Then all that is left is to blend thoroughly until seeing consistency in the particle size. Finally, sieve out the finer ground coffee for espresso or coarser ground for a French press.

Coffee beans contain all the nutrition and flavor profile. When you break the beans, all the particles will have more surface so hot water can seep in and extract all the goodies on the way to dripping. Then you will have a coffee with proper strength, color and flavor.

  • Better Flavor Extraction: The interesting thing is you can absolutely make a cup of coffee with whole beans. It just won't be a good one. You will lose most of the flavor as water can not get inside the beans properly. At this point, you should lower your expectations even if the beans you have are a special kind.
  • Fresh Brew: Compared to pre-ground Coffee, whole coffee beans start to deteriorate much more slowly after roasting. That’s one of the reasons coffee enthusiasts prefer whole beans. That way they can grind only the amount they need and enjoy fresh brew for days to come.
  • Minimize Wastage: To put into contrast, properly ground coffee results in a far better yield than pre-ground coffee. Naturally, you will add more coffee to balance your particular taste. That can add a huge amount of coffee wastage if you consume it regularly. So these are the fair reasons why coffee enthusiasts like to grind coffee beans rather than going for pre-ground coffee or even whole beans.

Grinding Coffee Beans With A Blender In 5 Steps

Grinding coffee beans in a blender isn’t something new that people are just finding out now. Some of us have been in a situation like in hotels or air BNBs where there is only a blender for use. Instinctively, you may have wondered “can I grind coffee beans in a blender?”. Well, you definitely can!

Step 1: Wash and dry the jar

Before you put any coffee beans in the blender pitcher, thoroughly wash the jar and pat it dry with a cloth. You can also hang dry if you have enough time to spare. The reason we have to clean the jar is because of the possible contamination.

Your blender may have residue from the last blending session and you don't want that in your coffee ground.

So clean it and prepare the jar for the next step of coffee grinding.

Step 2: Pour Coffee Beans

You should know that you cannot grind a few beans in a blender like a dedicated coffee grinder. The coffee grinder has a flat blade that is closer to the surface. This allows the blade to break a few coffee beans and still put a bite on the broken pieces of beans.

That's not the case with a blender. Blender usually comes with a cross blade and has quite an open surface around the blade.

So grinding a few beans would be more of a hit or miss and you will need more time to get to an acceptable consistency.

So the best practice would be to fill up to the edge of the blade or more to be safe.

As you grind the beans the overall level will decrease as the bean breaks down to fine particles.

Pour Coffee Beans

Step 3: Blend perfectly

Now that you have poured the coffee beans, it’s time to blend until you like the particle size. Always start with the lowest speed to avoid jamming and splatter. After a couple of seconds, speed up the grinder to the highest speed available.

You will see the finer particles are settling down and the coarse particles are shifting upwards. That is a good sign that blender is working great.

A good tip to speed up the process would be to slightly shake the jar without detaching it from the blender itself. You can also tilt the whole blender slowly for the same effect.

Blend perfectly

Step 4: Separating

Once you have reached the point where you see the particles are close to unified size, you are ready to separate the finer grounds. Although this is an optional step to fine-tune the flavor, you can follow this step if you have a sieve.

Alternatively, you can also use a pour-over paper filter or a french press to make delicious coffee right from the jar. Again, you might taste some irregularity due to inconsistent coffee grounds but it’s much better from whole bean coffee.

Step 5: Brewing Coffee

Lastly, give it as much time as you can to perform a slow brew. With time coffee flavors develop complexities and flavor notes. So leave the cup on the table for a couple of minutes and enjoy your perfect cup of freshly ground coffee.
