3 Ways to Grind Coffee Beans Without a Grinder


As a coffee lover, you know that grinding coffee beans just before brewing is the key to unlocking the freshest and most flavorful cup of coffee. But what if you find yourself without a coffee grinder? Fear not! In this ultimate guide, we'll explore three creative ways to grind coffee beans without a grinder, so you can still enjoy a delicious, aromatic cup of joe.

Why Grind Coffee Beans Fresh?

Grinding coffee beans right before brewing is essential because it helps preserve the coffee's natural flavors and aromas. When coffee beans are ground, they are exposed to oxygen, and the volatile compounds that contribute to the coffee's taste and fragrance start to degrade. By grinding fresh, you ensure that these flavorful compounds are captured in your cup.

What You'll Need

  • Coffee Beans: Choose high-quality coffee beans that match your taste preferences and the brewing method you plan to use.
  • Mortar and Pestle: This traditional grinding tool consists of a bowl (mortar) and a pestle (a small, heavy tool used to crush or grind).
  • Rolling Pin and Plastic Bag: A rolling pin is a cylindrical tool used in baking, and a plastic bag will serve as your makeshift coffee bean grinder.
  • Blender or Food Processor (Optional): If you have a blender or food processor, you can use it as an alternative grinding method.

Step-by-Step Guide

Note: The methods described below will produce coarsely ground coffee suitable for methods like French Press and cold brew. Adjust the grinding time for a finer grind, suitable for drip coffee makers or espresso machines.

Method 1: Mortar and Pestle

The mortar and pestle method is a classic and effective way of grinding coffee beans without a grinder.

Step 1: Place a small number of coffee beans into the mortar.

Step 2: Use the pestle to crush and grind the coffee beans in a circular motion. Apply firm pressure to break down the beans into your desired coarseness.

Step 3: Continue grinding until all the coffee beans are crushed evenly.

Step 4: Transfer the ground coffee to a container and repeat the process until you have enough ground coffee for your brew.

Method 2: Rolling Pin and Plastic Bag

The rolling pin and plastic bag method is simple and convenient, using items you likely already have in your kitchen.

Step 1: Place a small amount of coffee beans into a sturdy, resealable plastic bag.

Step 2: Seal the bag, leaving some room for the coffee beans to move.

Step 3: Lay the bag flat on a hard surface.

Step 4: Use the rolling pin to roll over the bag, crushing the coffee beans to your desired coarseness.

Step 5: Open the bag and check the grind consistency. If necessary, reseal the bag and continue rolling until all the beans are ground.

Step 6: Transfer the ground coffee to a container and repeat the process as needed.

Method 3: Blender or Food Processor (Optional)

If you have a blender or food processor at your disposal, you can use it to grind coffee beans quickly.

Step 1: Add a small amount of coffee beans to the blender or food processor.

Step 2: Pulse the machine in short bursts until you achieve the desired grind consistency.

Step 3: Check the ground coffee, and if needed, pulse a few more times to achieve an even grind.

Step 4: Transfer the ground coffee to a container and repeat the process as necessary.


Not having a coffee grinder doesn't have to keep you from enjoying a freshly brewed cup of coffee. With a little creativity and the right tools, you can grind coffee beans using a mortar and pestle, a rolling pin and plastic bag, or even a blender or food processor. Embrace the simplicity of these methods and savor the flavors of your freshly ground coffee, knowing you've mastered the art of making coffee without a grinder.
