Will a Coffee Grinder Grind Nuts?

Will a Coffee Grinder Grind Nuts? Yes, a coffee grinder can grind nuts effectively for small batches, producing nut flour, meal, or coarse chops. Blade grinders work well for this, while burr grinders may struggle with oil release and are better reserved for coffee.

Types of Coffee Grinders and Their Suitability for Nuts

Coffee grinders come in two main types: blade and burr.

Blade Grinders

• Use spinning propeller-like blades to chop ingredients.
• Ideal for grinding nuts into powder or butter in small quantities.
• Affordable and versatile for nuts, spices, and seeds.
• Produce uneven grinds but handle oily nuts better than burr models.

Burr Grinders

• Crush beans between two abrasive surfaces for uniform results.
• Excel at coffee but less suitable for nuts due to oil buildup clogging mechanisms.
• Conical or flat burrs provide consistency, but experts advise against using them for oily items like nuts to avoid damage.

Pros and Cons of Using a Coffee Grinder for Nuts

Pros:

• Convenient for small amounts (e.g., 1–2 oz for recipes).
• Creates fresh nut flour or meal quickly.
• Multi-purpose appliance saves kitchen space.
• Effective for almonds, walnuts, pecans, and peanuts.

Cons:

• Nuts release oils, leading to sticky residue and potential clogging.
• Over-grinding turns nuts into butter unintentionally.
• Difficult cleanup if switching back to coffee (flavor transfer).
• May wear out grinder faster with frequent use.
• Not ideal for large batches or smooth nut butter.

For nut butter, a food processor handles oils better and produces creamier results.

Tips for Grinding Nuts in a Coffee Grinder

Follow these steps for best results:

1. Use dry, roasted nuts – Toast lightly to enhance flavor and reduce moisture.
2. Work in small batches – Fill no more than halfway to avoid overheating.
3. Pulse in short bursts – 5–10 seconds at a time; shake grinder between pulses for evenness.
4. Monitor closely – Stop before oils release excessively to prevent paste.
5. Add sugar for finer grind – 1–2 tsp helps absorb oils in recipes like macarons.
6. Cool nuts first – Prevents quick butter formation.

These techniques yield coarse chops for toppings or fine powder for baking.

Cleaning Your Coffee Grinder After Grinding Nuts

Oily residue requires thorough cleaning:

• Immediate step: Grind uncooked rice (1/4 cup) to absorb oils; discard powder.
• Deep clean: Use grinder cleaning tablets like Urnex Grindz for oil removal.
• Manual method: Brush burrs/blades, wipe with damp cloth (avoid soaking motor).
• Dedicated grinder: Keep one for coffee and another for nuts/spices to prevent flavor crossover.

Regular cleaning extends grinder life and maintains taste purity. For detailed guides, see Wirecutter’s coffee grinder cleaning tips.

Alternatives to Coffee Grinder for Grinding Nuts

• Food Processor: Best overall; handles larger volumes, controls texture, ideal for nut butter.
• Blender: Good for powders; use pulse setting.
• Manual Methods: Mortar and pestle for small amounts; retains flavor but labor-intensive.
• Dedicated Nut Grinder: Optimal for frequent use.

Food processors offer superior versatility, as noted by Serious Eats experts.

FAQ

Can you make nut butter in a coffee grinder?
Possible in blade models with prolonged grinding, but results are chunky and messy. Food processor recommended for smooth butter.

Will grinding nuts ruin my coffee grinder?
Not immediately for occasional use, but oils accelerate wear and clogging, especially in burr grinders.

Which nuts grind best in a coffee grinder?
Harder, drier nuts like almonds and walnuts; softer oily ones like peanuts risk faster pasting.

How fine can you grind nuts in a coffee grinder?
To flour-like consistency with pulsing, though uneven compared to dedicated tools.

Is it safe to grind nuts if I also grind coffee?
Yes, with thorough cleaning; otherwise, flavors transfer.

Final Thoughts

A coffee grinder serves as a handy tool for grinding nuts in pinches, especially blade types for quick nut meals or flours. However, oils pose challenges, making dedicated appliances preferable for frequent or large-scale use. Prioritize cleaning and small batches for optimal results and longevity. For premium coffee grinding, reserve burr models exclusively for beans.
