Can You Grind Coffee Beans In A Blender? The Answer & How To Do

There are a lot of ways to grind coffee beans, and one of the methods is using a blender. Some people might wonder if it’s possible to do this, and the answer is yes – you can grind coffee beans in a blender!

However, there are a few things you need to know before you get started. In this blog post, I’ll discuss how to grind coffee in a blender and provide some tips for getting the best results.

Can You Grind Coffee Beans in a blender? [Science Behind Grinding]

Why do you grind coffee beans? The purpose of grinding coffee is to break the beans down into smaller pieces so that they can be brewed. This process also helps to release the coffee’s flavor and aroma.

When the beans are ground, it exposes more of their surface area to water, which is what extracts the coffee’s flavor. Consequently, anything that increases the exposed surface area in the same way as a grinder will accomplish the same thing.

So, you can grind your coffee in a blender, and it’ll work in a pinch. However, in the long run, a blender isn’t the best option for those who are serious about coffee or who like to enjoy a quality cup of joe.

Grinding Beans In A Blender (Necessary Information)

The blade system in blenders breaks down the coffee beans, similar to blade coffee grinders. The blades in the blender pitcher do the grinding work. In a blender, there is more room to grind coffee compared to blade coffee grinders.

The drawbacks of household blade grinders are they are tiny and don’t have enough volume. For an entire pot of coffee, you may have to grind two or more times, depending on how strong you want your coffee.

On the other hand, you can grind your coffee in a larger quantity and with greater consistency using a blender.

Consistency in the grind of coffee beans is key to producing the perfect cup. If the grind is inconsistent, the oils in the coffee beans are not extracted correctly, resulting in a bitter coffee.

A consistent grind will allow the beans to extract their oils and flavors in a much more accurate manner, resulting in a smoother cup of coffee.

A blender can produce a consistent grind if the beans are added gradually. That way, there will be plenty of room for beans to move and groove and grind up well.

In addition, working in small batches will preserve the aroma of the coffee beans. The reason is that the longer the blender runs, the higher the temperature inside the vessel will be.

The natural oils begin to cook as the beans heat up, producing a harsh, bitter taste. Therefore, make it a point to work in small batches and be patient!

How To Grind Coffee Beans With A Blender

I recommend adding only a small handful of coffee beans (20-25 grams or 1/4 cup) to your blender at a time. If you add more than that, the beans will have difficulty moving around and grinding evenly.

Add the beans to the blender and then pulse the blender for about five seconds. After five seconds, check to see how finely the beans are ground.

If they’re not ground to your liking, pulse the blender for a few more seconds. Repeat this process until the beans are ground to your desired consistency.

Once you’ve achieved the perfect grind, remove the lid of the blender and pour the grounds into an airtight container.

And that’s it! You’ve successfully ground your coffee beans using a blender.

Just remember to work in small batches, pulse the blender for short bursts, and remove the blender’s lid as soon as the beans are ground to your desired consistency.

Doing so will help to preserve the flavor and aroma of your coffee beans.

Blending generally produces a coarser grind suitable for steeping with a French press, drip coffee maker, or cold-brew machine.

How Does Grind Size Affect Coffee Taste?

Coffee grind size can greatly affect the taste of coffee. A coarse grind will result in a less intense, more mellow cup of coffee, while a fine grind will produce a more bitter, stronger cup of coffee.

The grind size can also affect the caffeine content of coffee. A finer grind will release more caffeine into the cup of coffee, while a coarser grind will result in less caffeine being released.

As well as the average particle size, there are other factors that affect the taste of the coffee, such as water temperature and extraction times. It is important to know the grind sizes that produce the flavor and caffeine content you prefer. 

Since it’s fractions of millimeters, you can’t precisely measure it. With time, you can train your eye to detect what looks like the appropriate grind size for your preferred method

How Do I Get the Proper Coffee Grind Size With A Blender?

It’s clear that there are two ends to the spectrum of grind size. It ranges from coarse to extra fine. Coarse particles are under 1 mm per particle, while extra-fine particles have just under 0.25 mm per particle. 

We cannot be certain of our eye’s ability to judge particle sizes when grinding coffee, so I do not recommend using a blender or any other blade grinder.

You will not only have difficulty determining what the average particle size is with these machines, but it will also be challenging to ensure consistency. 

I recommend using a burr grinder instead. Burr grinders can give you a more consistent grind size, and they also offer more control over the grind size.

That being said, if you still want to use a blender, I recommend starting with a coarse grind and then working your way up to a finer grind until you find the grind size that suits your taste.

Other Ways To Grind Coffee

If you don’t have a blender, or if you’re looking for other ways to grind coffee beans, there are plenty of options available to you.

You can use a mortar and pestle, food processor, or Rolling Pin or Hammer.

Mortar And Pestle:

This is a great option if you only need to grind a small amount of coffee beans. To use this method, simply add the beans to the mortar and use the pestle to grind them into a fine powder.

Food Processor:

This is a good option for those who need to grind a larger quantity of beans. Simply add the beans to the food processor and pulse until they’re ground to your desired consistency.

Rolling Pin Or Hammer:

If you don’t have a mortar and pestle or food processor, you can use a rolling pin or hammer to grind the beans. Place the beans in a Ziploc bag and use the rolling pin or hammer to crush them into a fine powder.

So there you have it! These are all great methods for grinding coffee beans without a blender & burr grinder.


In conclusion, can you grind coffee beans in a blender? The answer is yes, but it’s not the best option.

Burr grinders are the best option for grinding coffee beans, but if you don’t have one, you can use a mortar and pestle, food processor, or rolling pin or hammer.

So there you have it! I hope this post has helped clear up any confusion on how to grind coffee beans with a blender. Thanks for reading!
