How to Grind Coffee Beans Without a Coffee Grinder

Posted by Bean & Bean on January 31, 2023

Are you craving a fresh cup of coffee but don't have a grinder on hand? No problem! With a bit of creativity and some household items, you can grind your coffee beans without a grinder. In this article, we'll show you various methods, including a blender, food processor, and even a hammer. Don't let a lack of equipment stop you from enjoying a delicious cup of coffee.

Why grind size is important when making coffee

Grind size is essential when making coffee as it affects the coffee extraction, brew, and flavor. A fine grind will result in a larger surface area, leading to a stronger and more full-bodied cup of coffee. On the other hand, a coarse grind will result in a smaller surface area and a weaker, more watery cup of coffee.

The grind size also affects the extraction time. Fine grounds will extract faster than coarse grounds. Additionally, the grind size can affect the brewing method. For example, coarse grounds are suitable for a French press, while fine grounds are suitable for an Espresso machine. Therefore, choosing the right grind size is essential to brewing the perfect cup of coffee.

How to use a blender to grind coffee beans

Grinding coffee beans with a blender is a quick and easy method for those who don't have a grinder. Here's how to do it:

Measure out the desired amount of coffee beans you need for your brew.
Place the coffee beans in the blender, and pulse the blender on low speed for a few seconds at a time. Be sure to pulse, as opposed to letting the blender run continuously, otherwise the beans will be over-processed.
Check the grind size periodically, and pulse the blender until you reach the desired grind size.
Once you've achieved the desired results, use a spoon or a spatula to scoop out the ground coffee from the blender.
You can now use ground coffee for your desired brew method. Keep in mind that the grind size will be uneven and coarse, so this method is ideal for French press or cold-brew coffee.

It's important to note that using a blender to grind coffee beans may not produce an even grind size, and some of the grounds may be too fine or too coarse. Therefore, you should adjust your brewing method accordingly. Also, blending coffee beans can generate heat and cause the coffee to lose its aroma and flavor, so it's best to use the blended beans as soon as possible. It's also important to check the manufacturer's instructions for your specific blender to ensure that it is safe to grind coffee beans, this way you’ll avoid damaging the appliance.

How to use a food processor to grind coffee beans

A food processor is another option for grinding coffee beans. Like the blender, the ground coffee beans will not have an even grind size, but it’s still better than not having ground coffee! The process is similar to using a blender–here's how to do it:

Measure out the desired amount of coffee beans you need for your brew.
Place the coffee beans in the food processor, and pulse the blender on low speed for a few seconds at a time. Keep the food processor from running continuously, or the beans will be over ground.
Check the grind size periodically, and pulse the food processor until you reach the desired grind size.
Once you've achieved the desired grind size, pour the coffee grounds out of the processor and into a small bowl. Since a food processor can produce smaller grinds than a blender, we recommend sifting your coffee with a fine sieve to remove the ultra-fine grinds that can give you bitter-tasting coffee.

How to use a hammer to grind coffee beans

You can also use a hammer to grind coffee beans if you're in a pinch. We don’t recommend this method if you have access to machines like the blender or food processors as a hammer requires a lot of manual labor. However, it will do the job if it’s your only option. Here’s how to do it:

Measure out the desired amount of coffee beans you need for your brew.
Place the coffee beans in a plastic bag or between two sheets of parchment paper. Make sure the bag or paper is thick enough so it won't tear easily.
Hold the bag or paper down onto a durable surface with one hand and use a hammer to crush the beans with the other hand.
Crush the beans steadily and constantly, and stop periodically to check the grind size.
Once you've achieved the desired grind size, pour the grounds from the bag or paper into a small bowl.

It's important to note that using a hammer to grind coffee beans will produce coffee grounds of various sizes. Therefore, you should adjust your brewing method accordingly. Also, this method can be quite messy, as beans may fly out of the bag. If you're looking for a fine grind you’ll need to choose another option because the hammer can crush the beans unevenly and even leave some beans whole.

Why a coffee grinder is your best option

A coffee grinder is the best option for grinding coffee beans as it provides a consistent grind size and more precise control. Consistent grounds are important because they ensure that the coffee brews evenly, allowing for great flavor extraction and resulting in a better-tasting cup of coffee.

A coffee grinder also gives you more control over the grind size, which is essential for different brewing methods. For example, a French press requires a coarse grind, while an Espresso machine requires a fine grind. With a grinder, you can easily adjust the grind size to suit your desired brewing method, resulting in a perfect cup of coffee every time.

Furthermore, a coffee grinder is also easier to clean and maintain than other grinding methods and generates less heat. Additionally, a grinder won't affect the aroma and flavor of the coffee as much as other methods, allowing you to enjoy the full taste and aroma of your coffee beans.

Overall, a coffee grinder is a more efficient, precise, and effective tool for grinding coffee beans. It truly is an essential piece of equipment for any coffee lover.

Ready to invest in a grinder and avoid the hassle?

While there are many alternative methods to grind coffee beans, such as using a blender, food processor, or even a hammer, a coffee grinder is the best option for achieving consistent and flavorful cups of coffee.
