How To Grind Coffee Beans In A Blender

You do not need liquid when grinding coffee beans

Before diving into the process of grinding, we need to understand some background information. If you are planning to use your blender to grind your coffee beans, check if the blender has the grinding settings. Some blenders are designed with the setting, and it is meant to grind coffee.

So if your blender has the setting then you are at a vantage point.

Besides, blenders are known to work best with some liquid to help the solid move around. However, when grinding coffee beans you do not need the liquid. So, to prevent the blades from hanging and overworking the motor, make sure you grind in short quick bursts instead of letting the blades run.

The short quick bursts are also good for preventing the coffee beans from overheating. Overheated coffee beans tend to lose their natural oil and flavors and you may end up with a bitter-tasting brew.

It is preferred you use a glass blender like this instead of a plastic one. To start, a glass blender does not absorb food odors, oils, or flavors. As such, it may not release a random milkshake taste to your coffee beans and neither will your next fruit juice have traces of coffee.

Moreover, glass benders do not easily get scratches, especially when grinding hard items like coffee beans. It also does not get discolored given that coffee has a history of discoloring things. So, if you want to keep using your blender for its intended purpose after the coffee, use a glass blender for crushing your coffee beans.

Now that we have explored some basic guidelines, here is a step-to-step process of grinding your coffee beans in a blender.

Step1: Ensure the glass blender is tightly covered with its lid unless you are looking for an explosion of coffee beans on your counter. 

Step 2: Through the smaller opening, place a small number of coffee beans.

Step 3: Start the blender on the pulse setting to avoid the beans from being burnt. If the blender does not have the pulse setting, grind the coffee beans in a short quick burst allowing the blender to rest after roughly 10 seconds. If you are looking to brew a whole pot, the process may take longer due to the small grounds being processed. 

Step 4: Once you have grounded the beans to the coffee grounds of your preferred texture, proceed to brew your favorite cup of caffeine.

Other Methods Of Grinding Coffee Without A Grinder

If you are reading this, chances are, you are looking for viable ways to grind your coffee beans without a grinder. Well, we have done the work of you and listed other methods of grinding your beans other than using a blender.

Mortar and Pestle

Mortar and Pestle is traditional way of grinding coffee

Mortar and Pestle is one of the decent traditional ways of grinding coffee beans. Pharmacists have used this method to prepare the medicine. Cooks also have used it to crush and prepare spices.

As such, do not let a mortar and pestle lie around your kitchen as you sweat about having to buy coffee grounds instead of grinding them yourself. I mean, who does not want a fresh cup of coffee. 

Alternatively, if you do not already have a mortar and pestle, you can always buy a pair in the local kitchenware store.

Procedure

Step1: Put a small number of coffee beans in the mortar. A small amount is the best to help you achieve consistency.

Step2: Use your most active hand to hold the pestle and the other one to hold the motor firmly to the surface. A firm grip is important to make sure the mortar does not flip when grounding. 

Step 3: Using the pestle crush the coffee beans against the mortar. Be careful not to crush the grounds into un-filterable dust. When crushing the coffee beans stir them to make sure every ground is grounded evenly and consistently.

Step 4: If you need to grind more coffee, pour the ready grounds and start the process again until you achieve your desired amount of coffee grounds.

For these grounds, you will need about 2 tablespoons when brewing your coffee. Also, due to the great control of the size of grounds, the coffee grounds give you a range of grinds from French-press coarse to a Turkish coffee fine.

Hammer

A hammer, mallet, or meat tenderizer uses the same technique to crush your coffee beans to the desired size of your coffee grounds. However, when using these tools, be careful since it can not only crush the coffee beans but also your hand and well-designed kitchen counter.

Procedure

Step 1: Place the desired amount of coffee beans in a paper a bag.

Step 2:  Place the paper bag of grounds on the kitchen counter.

Step 3: Use your hammer, millet, or meat tenderizer to exert force to the grounds downwards.

Step 4: When crushing, turn the paper bag in all sides to ensure you crush all the beans and achieve a constituency in the grounds.

The grounds achieved in this process are usually coarse to medium in size. They, therefore, are best used when brewing cold coffee, for use in the Chemex or a drip coffee maker. Note that they are not the best grounds to brew an espresso.

Rolling Pin

A normal rolling pin can help you grind your coffee beans. It produces finer grinds as compared to other methods such as using the hammer. When using a rolling pin, you will need elbow grease for the rolling pin.

You will also need to be focused on grinding to make sure you are exerting the same force throughout the grind. 

Procedure

Step 1: Place some grounds in a plastic bag, push as many grounds as you can and seal the bag.

Step 2: Place the bag on a flat surface and start rolling throughout the coffee beans. Roll away from the opening of the bag to avoid pushing the contents out. 

Step 3: Roll the pin until you are sure you have attained consistency with the coffee grounds.

Due to the fragile nature of the paper bag, you may choose to cover it with a towel when grinding to avoid tear. However, note that this will increase the time you spend rolling the pin to achieve your desired grounds. If done right, grounds from a rolling pin are usually of medium to a fine texture. 

Food Processor

A food processor uses the same technique as a blender to grind coffee beans. Grounds resulting from a food processor are not exactly fine or consistent. Therefore, there is a need to apply the short quick bursts technique with a food processor.

Procedure

Step 1: Place a small number of coffee beans in the bowl of the processor and fit its lid tightly.

Step2: Use the pulse technique on the processor to perform the quick short bursts. While grinding, slightly tilt the processor from side to side. This helps the ungrounded beans to get into contact with the blades.

Step 3: Depending on your desired amount, pour out the ground and place new coffee beans to produce more grounds.

Knife

Unfortunately, using a knife to grind your coffee beans should be left for people who have experience of handling knives, preferably chefs.

When using a knife to grind your coffee, use the wide blunt surface of the knife. If you have a butcher knife or chef’s knife it is better since its slightly wider than the normal knife used in the kitchen.

Procedure

Step 1: Place the coffee beans on a flat surface or cutting board.

Step 2: Place the knife on the beans with the edges on the board. Place a towel on the knife to avoid coffee beans from flying everywhere.

Step 3: Place your palm on the knife and exert force firmly on the coffee beans.

Step 4: Once the coffee beans are broken continue pressing them down while grinding the blade towards you to make the grounds finer.

Can I brew coffee grounds that are not even or consistent? 

No, if you are looking to enjoy the true flavors oils, and content of coffee, you have to root for consistent grounds. When coffee grounds are not consistent, it means that some are bigger than others are. So, when hot water is poured into the grounds, the finer grounds release the flavors faster than the larger ones. Should you stop the process, you are likely to get a chalky tasting cup of coffee.

On the other hand, when the grounds are consistent the oils and flavors will be extracted at the same time, accurately, and result in a smooth cup of your favorite brew.

How do I attain consistency in my grounds? 

As mentioned throughout the article, the simplest way to make sure your grounds are even is by crushing a few beans at a time. I cannot stress this enough. Grounding small potions also gives you control over attaining the texture of the coffee you want.

You can also make sure you apply the same amount of pressure through the grinding process.

However, should you still end up with inconsistent grounds, do not fret, you do not have to discard them. You can use a French press to brew your cup of coffee. A French press is known to have more tolerance for inconsistent grounds and brewing course grounds.
