Mazzer Super Jolly Burrs: Everything About Replacing, Upgrading, and Choosing the Right Set

I bought a used Mazzer Super Jolly off Craigslist for $200 about three years ago. The grinder itself was in great shape, but the burrs were shot. They had been grinding in a cafe for years, and the cutting edges were visibly rounded. Replacing those burrs turned a tired machine into one of the best espresso grinders I have ever used. That experience taught me how much burrs matter, especially on a grinder with this much potential.

The Mazzer Super Jolly is a 64mm flat burr commercial espresso grinder that has been a staple in cafes worldwide since the 1990s. It is built like a tank, lasts for decades, and can be found used for $150 to $300 all day long. The burrs are the one consumable part, and choosing the right replacement set can dramatically change how this grinder performs.

When to Replace Your Super Jolly Burrs

Mazzer recommends replacing burrs after approximately 600 to 800 kg of coffee for the stock steel burrs. In a busy cafe grinding 10 to 15 kg per day, that means replacement every 2 to 3 months. For home use at 50 to 100 grams per day, the stock burrs can last 5 to 10 years.

Signs Your Burrs Are Due

  • Increased grind time. If the same dose takes noticeably longer to grind, the burrs are dull.
  • Inconsistent particle size. Worn burrs produce more fines and boulders. You will notice espresso shots running unevenly, with channeling that was not there before.
  • Difficulty dialing in. If you find that small grind adjustments produce wildly different results, the burrs may be worn unevenly.
  • Visual inspection. Remove the upper burr carrier and look at the cutting edges. Fresh burrs have sharp, defined ridges. Worn burrs look rounded and smooth.

I checked my used Super Jolly's burrs under a magnifying glass when I got it. The edges were completely rounded, almost polished. New burrs made an immediate and dramatic difference.

Stock Mazzer Burrs vs. Aftermarket Options

You have three main paths when replacing Super Jolly burrs: Mazzer OEM burrs, SSP aftermarket burrs, or other third-party options like Italmill.

Mazzer OEM Burrs

These are the same 64mm flat burrs Mazzer installs at the factory. They cost about $30 to $50 per set and are widely available.

Pros: - Designed specifically for the Super Jolly - Drop-in replacement, no modifications needed - Proven espresso performance with good body and sweetness - Cheap enough to replace regularly

Cons: - Lower grind uniformity compared to SSP burrs - Produce more fines, which adds body but reduces clarity - Shorter lifespan than coated aftermarket burrs

For most home users grinding dark or medium roasts for traditional espresso, OEM burrs are perfectly fine. They produce thick, sweet shots with good crema.

SSP Burrs for the Super Jolly

SSP (Sim Sung Precision) makes 64mm flat burrs that fit the Mazzer Super Jolly. The most popular options are:

  • SSP Multi-Purpose (MP): Balanced between clarity and body. Good for both espresso and filter. About $100 to $130.
  • SSP High Uniformity (HU): Maximum clarity and evenness. Best for light roast filter coffee. About $100 to $130.
  • SSP Cast V2: More body and sweetness than MP. Best for traditional espresso with medium to dark roasts. About $100 to $130.

SSP burrs produce a tighter particle distribution than OEM Mazzer burrs. In practical terms, this means cleaner-tasting cups with more defined flavor notes. The trade-off is less body and crema compared to OEM burrs, especially with the HU set.

Installing SSP burrs in a Super Jolly requires alignment work. The stock burr carrier does not always seat SSP burrs perfectly flat, so you need to do the marker test and shim if necessary. This is a 20 to 30 minute job that requires patience but no special tools.

Italmill and Other Third-Party Burrs

Italmill is an Italian burr manufacturer that makes replacement sets for Mazzer grinders. They cost about $40 to $60 and sit between OEM and SSP in quality. Good option if you want a modest upgrade without the cost or alignment hassle of SSP burrs.

How to Replace Super Jolly Burrs

The process is straightforward and takes about 15 to 20 minutes. Here is what I did:

  1. Unplug the grinder. Always.
  2. Remove the hopper. Twist it off and set it aside.
  3. Remove the upper burr carrier. There are usually 3 screws holding it in place. Remove them and lift out the carrier with the upper burr attached.
  4. Inspect and clean. Brush out all retained grounds from the grinding chamber, the chute, and both burr surfaces.
  5. Remove old burrs. The burrs are held to the carrier (upper) and the mounting plate (lower) by 3 screws each. Remove the screws and pop out the old burrs.
  6. Install new burrs. Place the new burrs and tighten the screws evenly. Do not overtighten.
  7. Reassemble. Put the upper carrier back in, reinstall the 3 carrier screws, and reattach the hopper.
  8. Align (if using aftermarket burrs). Use the dry erase marker test: coat both burrs with marker, set the grinder to zero (burrs touching), spin a few revolutions by hand, and check where the marker wears off. Adjust by shimming until the wear pattern is even across the full burr surface.
  9. Season the burrs. Run 2 to 5 kg of coffee through the grinder before judging flavor. New burrs need time to break in.

A Note on Alignment

Alignment is optional for OEM burr replacements (they are manufactured to Mazzer's tolerances), but it is strongly recommended for SSP burrs. Properly aligned SSP burrs in a Super Jolly produce grind quality that rivals grinders costing three to four times as much.

Super Jolly Burr Upgrades: Is It Worth It?

If you bought a used Super Jolly for $200 and spend $120 on SSP MP burrs, you have a grinder that competes with $800 to $1,000 retail grinders in grind quality. That is the single best value proposition in the espresso grinder market.

The motor, housing, and adjustment mechanism on the Super Jolly are overbuilt commercial components. The only weak point is the stock burrs, which are fine but not exceptional. Swapping in better burrs takes a great grinder and makes it excellent.

For home users who drink mostly medium to dark roasts and want classic espresso: stick with OEM burrs. They are cheap, easy to replace, and produce the body and sweetness that traditional espresso drinkers expect.

For home users who drink light to medium roasts and want more flavor clarity: SSP MP or HU burrs are worth the investment. The clarity improvement is real and consistent.

Frequently Asked Questions

How do I know which 64mm burrs fit the Mazzer Super Jolly?

The Super Jolly uses standard 64mm flat burrs with a 3-screw mounting pattern. OEM Mazzer burrs, SSP 64mm burrs, and Italmill 64mm burrs all fit. When ordering SSP burrs, specify "Mazzer 64mm" to ensure you get the correct mounting hole pattern.

Can I use the Super Jolly for filter coffee after upgrading burrs?

With SSP HU or MP burrs, yes. The Super Jolly's stepless adjustment goes coarse enough for drip and pour-over. The stock burrs are tuned more for espresso and do not perform as well at coarser settings. SSP burrs handle the full range better.

How much does it cost to replace Mazzer Super Jolly burrs?

OEM Mazzer burrs cost $30 to $50. SSP aftermarket burrs cost $100 to $130. Italmill burrs cost $40 to $60. Labor is free if you do it yourself (recommended, it is a simple job).

Do I need to season new burrs before judging flavor?

Yes. New burrs, especially SSP, need a break-in period. Run 2 to 5 kg of coffee through the grinder. During seasoning, the grind may taste slightly metallic or flat. After seasoning, the flavor opens up considerably. I seasoned mine with 3 kg of cheap supermarket beans before switching to good coffee.

The Takeaway

The Mazzer Super Jolly is one of the best grinder platforms in the used market because it pairs a bulletproof commercial body with easily replaceable burrs. Whether you stick with $40 OEM burrs or invest $120 in SSP aftermarket sets, a fresh set of sharp burrs transforms this grinder's performance. If you find a Super Jolly in good mechanical condition for under $300, buy it. The burr upgrade turns it into something special.
