Overview
The Mazzer Mini Doserless removes the traditional doser from the Mini platform for a more home-friendly design. Grounds fall directly into the portafilter or container, reducing retention and waste compared to the doser version. The same proven 64mm flat burrs and commercial-grade motor deliver reliable espresso grinding that has served the prosumer market for decades. The doserless configuration has become the preferred choice for home users who want Mazzer quality without the doser bulk and retention.
The Mazzer Mini Doserless 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 1.5g, typical for a hopper-fed workflow.
At $700, the Mazzer Mini Doserless 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 Mini Doserless is weighing 9.0 kg, manufactured in Italy, powered by a 250W motor. Its footprint measures 165 x 240 x 430 mm (W×D×H).

Our Verdict
The Mazzer Mini Doserless 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 Mini Doserless grind fine enough for espresso?
Yes, the Mazzer Mini Doserless 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 Mini Doserless?
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 Mini Doserless?
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 Mini Doserless worth $700?
The grinder is the most important variable in espresso quality — more important than the machine. Investing in a quality grinder like the Mazzer Mini Doserless 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.
