How to Grind Coffee Beans Without a Coffee Grinder

The following is a list of 7 methods of grinding coffee beans with some basic kitchen tools and of course, the most important element: COFFEE BEANS!!

1) Using a Kitchen Blender

All you’ll need for this method is your coffee beans, and of course your basic kitchen blender.

  • Take a quarter of the coffee beans and pour them into the blender.
  • After setting the blender to the low or grind setting, cover it with the lid and start to pulse the coffee beans for about 10 seconds.
  • After the beans have been crushed, add the next quarter of coffee beans and repeat the process.
  • Continue adding coffee beans until you’ve achieved the right amount of coffee grounds and of the coffee is ground to your required consistency.
  • If you are using an older blender, it may be difficult to get a fine grind consistency.
  • Once you’re done, make sure you wash the blender properly to get rid of all the coffee flavor and smell.

Here’s a tip:

You’ll get much better results if you pulse the blender in short bursts. Else, the blades will heat up and spoil the taste of your coffee.

2) Using a Food Processor

A food processor is nothing but a larger blender with bigger blades. There are different sizes and designs of a food processor but the method is almost the same as the blender.

  • Measure a scoop of coffee beans and pour them into the food processor. Make sure the lid is properly secured.
  • The pulse technique that we used in the case of the blender, remains the same, grinding the coffee beans in short intervals.
  • You may want to tilt the food processor slightly from one side to another to get better results while grinding.
  • Add the next batch of beans and repeat the process till you get the desired quantity of ground coffee.

The food processor will give better results than the blender and you’ll get a finer grind.

3) Using a Hammer

You’re going to like this one:

Are you looking for a way to vent out your frustration and tension without causing harm to your loved ones? Well, you can do that with this method, and enjoy a nice cup of joe afterward.

  • Get a hammer or a meat tenderizer and your coffee beans.
  • You’ll also need a high-quality plastic bag.
  • Pour the beans in the plastic bag and cover it with one or two pieces of towel or any cloth.
  • Start gently crushing and grinding the coffee beans until you get the fine grind that you desire.

This technique may be a little rough and explosive but it may just be the perfect stress buster you’ve always been looking for!

4) Using a Mortar and Pestle

This technique involves no electrical appliances and it is the most traditional method of grinding when there were no gadgets or machines around.

Hence, this method may take some time and be a little tiresome, but it will work perfectly. The technique involves muddling, rolling, hammering motions that assist to make a fine grind.

  • Scoop 1 to 2 tablespoons of coffee beans and put them into the mortar.
  • Cover the top of the mortar with one hand and use the pestle to swirl and mash the beans in the mortar, making sure that none of the beans spillover.
  • The longer you do this the finer your grind will be.


It’s best to do this in small quantities at a time. This will ensure a fine grind and will prevent spillage over the edge of the mortar.

5) Using a Cutting Board and a Knife

Another method that doesn’t require any advanced electrical appliances or tools to grind and crush coffee beans. All you’ll need is a broad-bladed knife and a solid cutting board.

  • Take a handful of coffee beans and place them on a large cutting board, preferably wooden. If you have a large butcher’s knife, then use that!
  • Take the flat blade and place it on the coffee beans. A chef’s or butcher knife will give you a wider flat surface, giving you additional leverage to make the process of cracking and grinding the beans easier.
  • By exerting pressure on the blade to crush the beans, the beans will crack open into multiple pieces.
  • Do this until the beans get finer and finer.

This method may not give you the finest grind. However, if a medium-grind will work for you, then you’re golden.

6) Using a Rolling Pin


A rolling pin was not the first thing that came to mind, when looking for something to use for this task. However, this method can be very effective.

  • Take a handful of coffee beans and put them inside a high-quality plastic bag.
  • Make sure that you release all the extra air from the bag and seal it. Because the presence of any air will burst the bag once you start rolling.
  • Use the rolling pin to gently roll over the coffee beans in the bag.
  • The more you roll, the finer the grind will be.


Use dark roasted coffee beans. This will allow you to easily judge the consistency of the grind, and allow very fine powder, as used for Turkish Coffee and your French Press.

7) Using a Hand Mincer

At some point in your life, you must have used a pencil sharpener.

Hand mincers have very similar functionality and are used to mince many different types of vegetables, spices, herbs, and even meat.


If you have one of these awesome little machines you’ll be able to mince (grind) your coffee beans without much effort.

  • Take some coffee beans that need grinding. Measure and place it aside.
  • Take a measuring cup or a large bowl and place it where the coffee powder is going to exit from the mincer.
  • Start to rotate the hand crank and gradually keep pouring the coffee beans into the hand mincer.

As the coffee grind collects in the bowl, you can use that, or you can make it finer by running all the steps again, based on how fine or coarse you want your coffee to be.

Here’s the Bottom Line

No matter whichever method you use, make sure that you store the crushed coffee in an airtight coffee jar.

The higher the quality of whole-bean coffee, the better the grinding and brewing of the coffee.

Do not overheat the beans as it will make the beans bitter and harder.

Knowing these nifty hacks will allow you to enjoy fresh, natural flavored, delicious coffee every morning after you wake up.
