Overview
The Mazzer Major steps up from the Super Jolly with 83mm flat burrs for superior grind uniformity and faster throughput. This is a serious commercial grinder that some dedicated home baristas adopt for its outstanding grind quality. The large burr set produces remarkably uniform particles, and the powerful motor handles any roast with ease. Retention is high by modern standards, making it best suited for high-volume use or hopper workflows. The Major is built like a tank and will likely outlast its owner. For home users willing to deal with its size and retention, the grind quality — especially with aftermarket burrs — is genuinely exceptional and can rival grinders costing several times more.
The Mazzer Major features a 83mm flat burr set, crafted from steel. The burrs spin at 1400 RPM, offering fast grinding for high-volume use. Grind retention is approximately 3.5g, typical for a hopper-fed workflow.
At $1,500, the Mazzer Major is aimed at uncompromising enthusiasts and professionals who want the absolute best. 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 Major is weighing 18.0 kg, manufactured in Italy, powered by a 500W motor. Its footprint measures 240 x 310 x 650 mm (W×D×H).
Pros & Cons
Pros
- Large 83mm burrs deliver fast, consistent grinding with excellent particle uniformity
- Stepless grind adjustment allows infinite precision for dialing in any coffee to perfection
- Flat burr geometry produces highly uniform particle distribution, prized for clarity and sweetness in espresso
Cons
- Not optimized for single dosing — hopper-fed design may result in some grind exchange between doses
- Higher retention (3.5g) means some grounds are retained between uses, affecting freshness for single-dose workflows
- Premium pricing at $1,500 puts it out of reach for most home setups

Our Verdict
The Mazzer Major 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. This is an end-game grinder for dedicated enthusiasts. The price is substantial but reflects the engineering required for top-tier particle uniformity. 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 Major grind fine enough for espresso?
Yes, the Mazzer Major 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 Major?
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 Major?
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 Major worth $1,500?
The grinder is the most important variable in espresso quality — more important than the machine. Investing in a quality grinder like the Mazzer Major 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.
