Grinding your own coffee beans is one of the best ways to enjoy fresh, flavorful coffee. While burr grinders are the top choice for serious coffee lovers, many people wonder if they can use their high-powered blender instead. One popular option is the Blendtec blender. But can it really do the job? In this article, we’ll explore whether you can grind coffee beans in a Blendtec, how to do it correctly, what grind sizes you can expect, and how it compares to traditional grinders.
Can You Grind Coffee Beans in a Blendtec?
Yes, you can grind coffee beans in a Blendtec blender. Blendtec blenders are known for their strong motors and sturdy blades. They are powerful enough to break down hard ingredients like ice, nuts, and yes—coffee beans. While not originally designed for coffee grinding, Blendtec machines can produce a grind suitable for several brewing methods.
Blendtec’s blades are thick, dull-edged, and made for high-speed blending. They don’t slice like traditional coffee grinder blades but pulverize with force. This, combined with a motor that can reach up to 3 peak horsepower, makes them capable of grinding beans fairly quickly.
That said, because the blades aren’t specifically designed for grinding coffee, achieving a consistent grind can be tricky. It’s definitely possible, but technique and timing matter.
How to Grind Coffee Beans Using a Blendtec
Here’s a simple step-by-step guide to grinding coffee beans with a Blendtec:
Choose the Right Container: Use the standard WildSide+ or FourSide jar. Make sure it’s completely dry to avoid clumping.
Measure Your Beans: Start with about ½ to 1 cup of coffee beans. Grinding too much at once can lead to overheating and uneven results.
Use Pulse Mode: Instead of running a full blend cycle, use the pulse button in short bursts. This gives you more control and prevents the beans from overheating.
Shake Between Pulses: Lightly shake the container between pulses to move larger pieces toward the blades.
Check the Grind: Stop and check your grind consistency every few pulses. Adjust based on your brewing method.
Store Immediately: Transfer your ground coffee to an airtight container to keep it fresh.
Recommended Settings and Techniques
Pulse Duration: 1-2 second bursts
Total Time: 10–20 seconds depending on desired grind size
Rest Between Pulses: Let the motor rest 5 seconds between bursts
Batch Size Tips
Avoid grinding large batches. Stick to small amounts (under 1 cup of beans) to prevent uneven grinding and heat buildup, which can alter flavor.
Grind Size & Brewing Methods
Grind size affects flavor and brew time. Here’s what you can typically achieve with a Blendtec:
Coarse Grind: Possible with just a few short pulses. Ideal for French press and cold brew.
Medium Grind: Achievable with slightly longer pulse sessions. Works well for drip coffee and pour-over.
Fine Grind: More challenging. May require extra pulses and shaking. Can be used for AeroPress or moka pot.
Brewing Methods Suited to Blendtec Grinds
French Press: Yes
Cold Brew: Yes
Drip Coffee Maker: Yes
Pour Over: Yes
Espresso: Not recommended (grind is often too uneven)
Turkish Coffee: Not suitable (requires ultra-fine powder)
Comparison with Traditional Grinders
Burr Grinders: Offer precise, consistent grind size control. Ideal for espresso.
Blade Grinders: Similar to Blendtec in concept, but Blendtec is more powerful.
Manual Grinders: More effort but very consistent, especially for fine grinds.
Tips for Best Results
Getting the most out of your Blendtec for coffee grinding takes a little finesse. Here’s how:
1. Pulse Grind for Even Consistency
Use quick, controlled pulses rather than long blends. It reduces friction heat and gives you more control over the grind size.
2. Prevent Overheating
Grinding for too long can heat the beans and change the flavor. Stick to short bursts and allow the motor to cool between pulses.
3. Use a Dry Blender Container
Any moisture in the jar will cause the coffee grounds to stick to the sides and clump together. Always dry your container thoroughly before grinding.
4. Sift Your Grounds (Optional)
For more uniform results, use a fine mesh sieve to sift out larger chunks after grinding.
5. Clean the Jar Thoroughly
Coffee oils can linger and affect the taste of other blended foods. Clean the jar with soap and warm water immediately after grinding.
Potential Drawbacks & Considerations
While the Blendtec is capable of grinding coffee beans, there are some trade-offs.
Inconsistent Grind Size
The Blendtec’s blades are not optimized for uniform particle size. You may find a mix of fine powder and coarse chunks.
Not Ideal for Espresso or Turkish Coffee
These brewing methods require a fine, uniform grind, which is hard to achieve with a Blendtec.
Blender Wear and Tear
Grinding coffee frequently can dull the blades and wear down the motor faster than typical smoothie use.
Noise and Heat
Blendtec blenders are loud, especially when grinding beans. They also generate heat, which can affect coffee flavor.
Alternative Methods & Comparisons
Blendtec vs. Other Blenders
Vitamix: Also capable of grinding beans with pulse technique. Similar performance.
Nutribullet/Magic Bullet: Less powerful, may struggle with consistent results.
Ninja: Decent results for coarse and medium grinds, but not great for fine grinding.
Blendtec vs. Burr Grinder
Grind Quality: Burr grinder wins for consistency.
Convenience: Blendtec is a two-in-one appliance.
Cost: If you already own a Blendtec, no extra cost needed.
Other Creative Grinding Methods
Mortar and Pestle: Labor-intensive, but gives good control.
Rolling Pin: Place beans in a bag and crush—primitive but works.
Manual Hand Grinder: Affordable and gives precise results.
Conclusion
So, can you grind coffee beans in a Blendtec? Absolutely. While it may not replace a high-end burr grinder, Blendtec blenders are powerful enough to handle small batches of beans for most everyday brewing methods. With proper technique—using pulse mode, keeping batch sizes small, and checking consistency—you can achieve grind sizes suitable for French press, pour-over, and drip coffee.
However, for ultra-consistent grinds or espresso-level fineness, you’ll need a dedicated coffee grinder. Use your Blendtec as a versatile backup, not your main tool if coffee quality is a top priority.
Remember to clean your blender thoroughly after grinding to avoid flavor transfer, and always use a dry container. Happy brewing!
