Coffee Mixer Grinder: Can You Use a Mixer Grinder for Coffee Beans?

Yes, you can use a mixer grinder to grind coffee beans, and millions of people in India and Southeast Asia do exactly that every day. A mixer grinder (the countertop appliance with multiple jars and a powerful motor) works similarly to a blade grinder, chopping beans into smaller pieces with a spinning blade. It gets the job done, but the results are different from what you'd get with a dedicated coffee grinder.

I experimented with grinding coffee in my wife's mixer grinder for about three months before buying a burr grinder, and I want to share what actually works, what doesn't, and how to get the best possible results if a mixer grinder is your only option.

How Mixer Grinders Handle Coffee Beans

A mixer grinder uses a flat or multi-prong blade spinning at high RPM to chop whatever you put in the jar. For coffee beans, this means the blade strikes beans randomly, breaking them into pieces of varying sizes. Unlike a burr grinder that crushes beans between two surfaces at a controlled distance, a mixer grinder has no mechanism to control particle size.

The result is a mix of fine powder, medium particles, and larger chunks in every batch. The longer you run the mixer, the finer the overall grind gets, but you can never eliminate the inconsistency. Some particles get hit by the blade 20 times while others bounce around the edges and barely get touched.

What This Means for Your Coffee

  • Drip coffee makers and auto-drip machines work okay with mixer-ground coffee. The paper filter catches most of the ultra-fine particles, and the inconsistency is less noticeable in drip brewing.
  • South Indian filter coffee is where mixer grinders actually excel. The traditional method uses a metal filter that tolerates a wide particle range, and the strong, dark roasts used in South Indian coffee are forgiving of uneven grinds.
  • French press suffers because fine particles slip through the mesh filter, making muddy, over-extracted coffee.
  • Pour-over and espresso don't work well at all. These methods need precise, uniform particle sizes that a mixer grinder cannot produce.

Tips for Better Coffee from a Mixer Grinder

If you're committed to using your mixer grinder for coffee, these techniques will improve your results:

Use the Smallest Jar

Most mixer grinders come with 3 jars of different sizes. Use the smallest one (the chutney jar or spice jar) for coffee. The smaller volume keeps beans closer to the blade and produces a more even grind than the large liquidizer jar.

Pulse in Short Bursts

Don't hold the button down for 30 seconds straight. Instead:

  1. Pulse for 3 seconds
  2. Stop and shake the jar to redistribute beans
  3. Pulse again for 3 seconds
  4. Repeat until you reach your desired fineness

This technique moves beans that were hiding in corners back toward the blade. Five or six pulses with shaking between each one produces much better results than one long continuous run.

Grind Small Batches

Never fill the jar more than halfway. I found that 30 to 40 grams of beans in the small jar gives the best results. Larger quantities mean more beans escaping the blade and more inconsistency in the final grind.

Sift the Grounds

After grinding, pour the coffee through a fine mesh sieve. Tap the sieve gently and collect the fine particles that fall through separately from the coarser pieces on top. Use the fines for drip or South Indian filter. Use the coarser portion for French press or cold brew. This extra step takes 30 seconds and significantly improves cup quality.

Mixer Grinder vs. Dedicated Coffee Grinder

Let me lay out the comparison honestly, because this is the question behind most "coffee mixer grinder" searches.

Mixer Grinder Advantages

  • Already in your kitchen. No extra purchase needed. If you own a mixer grinder, you can start grinding coffee today.
  • Multi-purpose. You can grind spices, make chutneys, blend batters, and grind coffee with the same appliance.
  • Powerful motor. Mixer grinders typically have 500W to 750W motors, which handle even hard, light-roast beans without stalling.
  • Available everywhere. In India and Southeast Asia, mixer grinders are in nearly every household.

Dedicated Coffee Grinder Advantages

  • Consistent grind size. Burr grinders produce uniform particles at every setting, which translates directly to better-tasting coffee.
  • Adjustable settings. You can dial in a specific grind size for your brew method and repeat it exactly every time.
  • Less heat. Burr grinders (especially hand grinders) generate less heat than a high-speed mixer, which preserves flavor compounds in the beans.
  • Better flavor. This is the bottom line. The same beans ground in a burr grinder will produce a noticeably better cup than when ground in a mixer.

For people who drink coffee daily and want to improve their cup quality, a dedicated grinder is worth the investment. Check our best coffee grinder guide for options across all budgets. If you want to see top-rated picks, our top coffee grinder roundup has you covered.

Common Mistakes When Grinding Coffee in a Mixer

I made all of these mistakes during my three months with the mixer grinder, so learn from my experience:

  • Running the mixer too long. Extended grinding generates heat that can scorch the coffee oils and create a burnt, bitter taste. Keep total grinding time under 30 seconds.
  • Not cleaning between uses. If you grind turmeric or cumin in the same jar, those flavors will transfer to your coffee. Either dedicate one jar exclusively to coffee or clean thoroughly with baking soda between uses.
  • Grinding too much at once. Ground coffee goes stale within hours. Only grind what you need for that day's coffee. I know it's tempting to grind a week's worth at once, but you'll notice the flavor dropping off by day 3.
  • Using the wet grinding jar. Some mixer grinders have a jar with a different blade designed for wet grinding (batters, pastes). Don't use this for coffee. The dry grinding jar or chutney jar produces much better results.
  • Expecting espresso results. A mixer grinder will never produce espresso-quality grounds. If espresso is your goal, you need a burr grinder with fine adjustment capability.

Alternative Budget Options

If you're using a mixer grinder because a dedicated coffee grinder seems expensive, consider these budget-friendly alternatives:

  • Manual hand grinder ($15 to $30). A basic ceramic burr hand grinder produces significantly better results than a mixer grinder. It takes 1 to 2 minutes of manual cranking per cup, but the improvement in flavor is noticeable from the first brew.
  • Entry-level electric burr grinder ($40 to $60). Brands like Bodum and Hamilton Beach make basic electric burr grinders that outperform any mixer grinder for coffee.
  • Used grinder. Check local classifieds for used Baratza or Breville grinders. People upgrade frequently and sell their old grinders for a fraction of the original price.

FAQ

Can a mixer grinder grind coffee as fine as espresso?

A mixer grinder can produce very fine particles if you run it long enough, but the grind won't be uniform. You'll have a mixture of powder and larger particles. This doesn't work for espresso, which needs a uniform fine grind to extract evenly under pressure. The fine powder clogs the portafilter while the larger particles under-extract, giving you a sour and bitter shot simultaneously.

Does grinding coffee in a mixer grinder damage the blades?

No. Coffee beans are softer than many spices that mixer grinders routinely handle (like dried turmeric or peppercorns). The blades will handle coffee without any damage. Over years of use, all blades dull regardless of what you grind, but coffee won't accelerate that process.

How do I remove coffee smell from my mixer grinder jar?

Grind a tablespoon of raw rice in the jar, then wipe clean. The rice absorbs oils and odors. For stubborn coffee smell, make a paste of baking soda and water, coat the inside of the jar, let it sit for 30 minutes, then rinse thoroughly. This works for removing coffee residue from spice jars and vice versa.

What grind time should I use for different brew methods?

As a rough guide for a 30 to 40 gram batch in the small jar: - South Indian filter: 15 to 20 seconds total (with pulsing) - Drip coffee: 10 to 15 seconds total - French press: 5 to 8 seconds total (you want it coarse) - Cold brew: 5 to 7 seconds total

These times vary by mixer grinder model and motor power. Start with less time and adjust based on the appearance of the grounds.

My Honest Recommendation

A mixer grinder works for coffee in the same way that a screwdriver works as a pry bar. It gets the job done, but it's not designed for it. If coffee quality matters to you, save up for even a basic burr grinder. If you're using a mixer grinder as a temporary solution or you mostly make South Indian filter coffee, apply the techniques above and you'll get reasonable results. Just don't expect specialty coffee shop quality from a kitchen appliance designed for chutneys.
