Overview
The Mazzer Super Jolly is one of the most iconic espresso grinders ever made. Found in cafés worldwide for decades, it has earned its reputation through sheer reliability and consistent grind quality. The 64mm flat burrs and powerful motor handle high-volume grinding effortlessly. While modern single-dose grinders have surpassed it in retention and workflow, the Super Jolly remains a compelling option — especially on the used market where they can be found at significant discounts. Many home baristas have modded their Super Jollys with aftermarket burrs and single-dose hoppers, creating capable performers that rival far more expensive grinders. A true workhorse of the coffee industry.
The Mazzer Super Jolly features a 64mm flat burr set, crafted from steel. The burrs spin at 1600 RPM, offering fast grinding for high-volume use. Grind retention is approximately 3.0g, typical for a hopper-fed workflow.
At $900, the Mazzer Super Jolly is aimed at dedicated prosumers who demand top-tier grind consistency. Key workflow features include stepless grind adjustment for infinite precision. The flat burr design produces a more uniform particle distribution, prized for clarity and sweetness in the cup.
The Mazzer Super Jolly is weighing 12.5 kg, manufactured in Italy, powered by a 350W motor. Its footprint measures 200 x 290 x 580 mm (W×D×H).

Our Verdict
The Mazzer Super Jolly uses flat burrs, which are the preferred geometry for espresso among competition baristas and specialty coffee professionals. Flat burrs produce a more unimodal (uniform) particle distribution, which translates to cleaner, sweeter espresso with more clarity than conical alternatives. The mid-range price buys you a grinder that should be the last one most home baristas ever need. Pair it with a machine that does justice to the grind quality, and you'll taste the difference in every shot.
Frequently Asked Questions
Can the Mazzer Super Jolly grind fine enough for espresso?
Yes, the Mazzer Super Jolly is capable of grinding fine enough for espresso. Its stepless adjustment allows you to dial in precisely for any coffee.
Why choose flat burrs in the Mazzer Super Jolly?
Flat burrs produce a more uniform (unimodal) particle distribution compared to conical burrs. This translates to cleaner, more transparent espresso flavors with pronounced sweetness and clarity. Many competition baristas and specialty roasters prefer flat burr grinders for this reason.
How do I maintain the Mazzer Super Jolly?
Clean out retained grounds after each use with a brush or bellows. Deep clean the burrs every 2-4 weeks by removing them and brushing away oil buildup. For the motor, occasional use of grinder cleaning tablets (like Grindz) helps remove coffee oil buildup. Never wash burrs with water.
Is the Mazzer Super Jolly worth $900?
The grinder is the most important variable in espresso quality — more important than the machine. Investing in a quality grinder like the Mazzer Super Jolly will have a bigger impact on your espresso than upgrading any other piece of equipment. If you're serious about espresso, this level of grinder investment is justified.
