Mazzer Super Jolly Electronic: The Commercial Workhorse for Home Espresso
The Mazzer Super Jolly Electronic is a commercial-grade espresso grinder with 64mm flat burrs and an electronic dosing timer. It was originally designed for busy coffee shops, and many home espresso enthusiasts pick up refurbished units because the grind quality rivals machines costing twice as much. If you're looking at a Super Jolly for your kitchen counter, I'll tell you exactly what to expect, both the good and the not-so-good.
I bought a refurbished Super Jolly Electronic about two years ago from a decommissioned cafe, and it's been my daily espresso grinder since. I'll cover grind quality, noise, workflow, the electronic timer, and whether this commercial beast actually makes sense in a home setting. There are real tradeoffs you need to understand before committing.
The 64mm Flat Burrs and Grind Quality
The Super Jolly uses Mazzer's 64mm flat steel burrs, and these are the heart of why people seek this grinder out. The grind quality for espresso is outstanding. Consistent particle distribution, fluffy output that distributes well in the portafilter, and enough adjustment range to dial in any bean from light Nordic roasts to dark Italian blends.
I've pulled side-by-side shots comparing the Super Jolly to a Eureka Mignon Specialita, and the Mazzer produces a more even extraction with better clarity in lighter roasts. The difference is subtle but real if you're paying attention. Darker roasts taste equally good on both.
The Stepless Adjustment Collar
The grind adjustment on the Super Jolly is stepless, meaning there are no clicks or detents. You turn the collar smoothly from fine to coarse. This gives you infinite precision, which is great for dialing in, but it also means you can't "count clicks" to return to a previous setting.
My workaround: I use a fine-tip marker to make tiny lines on the collar and the body at my go-to settings. It's low-tech but effective. Some people stick small numbered stickers around the collar instead.
The Electronic Timer: How It Works
The "Electronic" in the name refers to the dosing system. Instead of the older doser chamber that required you to pull a lever, the Electronic model has a timed dosing button. You press the button, the grinder runs for a set number of seconds, and it stops automatically.
You adjust the grind time with a small dial on the front. I have mine set to about 5.5 seconds for a standard 18-gram dose. The timer is reasonably consistent, usually delivering within 0.3-0.5 grams of the target weight. That's not as precise as weighing every dose, so I still keep a scale nearby for shots where I want exact measurements.
Timed vs. Weighed Dosing
For my weekday morning routine, I trust the timer. It's fast, and being 0.3 grams off doesn't ruin my shot. On weekends when I'm experimenting with new beans or dialing in a fresh bag, I weigh every dose. The timer gives you speed; the scale gives you precision. I use both depending on the situation.
Size, Weight, and the Counter Space Problem
Here's where reality hits. The Mazzer Super Jolly is a commercial grinder. It weighs about 27 pounds and stands roughly 23 inches tall with the hopper attached. That's significantly larger than any home grinder on the market.
My kitchen has limited counter space, and the Super Jolly takes up a noticeable chunk of it. I moved my toaster to a cabinet to make room. If your kitchen is small, measure carefully before buying. The footprint is about 7 x 9 inches, but the height is the real issue, especially if you have low-hanging cabinets above your counters.
Removing the Hopper
One trick for reducing the height: swap the standard 3-pound hopper for a single-dose hopper or a 3D-printed single-dose conversion kit. This cuts 6-8 inches off the top and converts the grinder to a single-dose workflow. I did this after the first month and never looked back. It also solved the stale-bean problem from leaving beans in a large hopper.
Noise: The Elephant in the Room
The Super Jolly is loud. Not "a little louder than a home grinder" loud. It's commercial-equipment loud. During grinding, I'd estimate 80-85 decibels, which is comparable to a garbage disposal or a loud blender. My espresso dose grinds in about 5-6 seconds, so it's brief, but early morning grinding will definitely wake up other people in the house.
I grind my first shot at 6 AM, and my wife has commented on it. More than once. If noise sensitivity is a concern in your household, a home-focused grinder like the Eureka Mignon series or a Niche Zero will be dramatically quieter.

Buying a Used Super Jolly: What to Check
Most home buyers get their Super Jollys secondhand. Here's what to inspect:
- Burr condition: Remove the top burr carrier and look for uneven wear, chips, or smooth spots. Replacement burrs cost about $35-50 and are easy to swap.
- Motor sound: Run the grinder empty and listen for any grinding, clicking, or uneven sounds. The motor should hum smoothly.
- Adjustment collar: Turn it through the full range. It should move smoothly without catching or jumping.
- Wiring: Check the power cord and internal wiring for any damage or exposed copper. Commercial kitchens can be rough on equipment.
- Timer accuracy: Set the timer and run it 5 times. The grind duration should be consistent within half a second each time.
A used Super Jolly in good condition typically costs $200-400, which is an incredible value for 64mm flat burr quality. New units retail for around $800-1,000.
Maintenance Schedule
The Super Jolly is built for commercial use, so maintenance is minimal and parts are widely available.
- Weekly: Brush out the burr chamber and chute with a grinder brush
- Monthly: Run grinder cleaning tablets (like Urnex Grindz) through the burrs
- Every 6 months: Remove burrs for a deep clean, check for wear
- Every 2-3 years (home use): Replace burrs. Mazzer burrs are standardized and available from multiple suppliers for $35-50
The motor is rated for commercial duty cycles, so home use barely stresses it. I've seen Super Jollys running strong after 15+ years in cafes. For home use, the machine will likely outlast your kitchen.
FAQ
Is the Mazzer Super Jolly good for home use?
Yes, if you can handle the size and noise. The grind quality is excellent, parts are cheap and widely available, and the build quality means it will last decades. The main downsides are the large footprint (27 lbs, 23 inches tall) and the noise level during grinding.
How does the Mazzer Super Jolly compare to the Mazzer Mini?
The Mini uses 58mm burrs versus the Super Jolly's 64mm. The Super Jolly produces a more consistent grind, grinds faster, and handles lighter roasts better. The Mini is significantly smaller and quieter, making it more practical for small kitchens. Both are excellent espresso grinders.
Can you single-dose with the Mazzer Super Jolly?
Yes, with modifications. The stock hopper holds about 3 pounds of beans, but you can replace it with a single-dose hopper or bellows conversion kit. This reduces height, eliminates stale beans, and gives you dose-by-dose control. Retention is about 1-2 grams, so expect some exchange grind when switching beans.
How often do Mazzer Super Jolly burrs need replacing?
For home use at 3-4 shots per day, the 64mm burrs should last 3-5 years before you notice degradation. In a commercial setting grinding 5+ pounds per day, replacement is typically every 6-12 months. Aftermarket burrs cost $35-50 and take about 10 minutes to install.
The Verdict
The Mazzer Super Jolly Electronic is the best value in espresso grinding if you buy used and can tolerate the size and noise. The 64mm flat burrs produce commercial-quality grinds, the machine is virtually indestructible, and replacement parts cost next to nothing. If you want top-tier espresso grinding for $200-400 and have the counter space, hunt for a clean refurbished unit.
