Our Verdict
The Rocket Macinatore 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 Rocket Macinatore grind fine enough for espresso?
Yes, the Rocket Macinatore is capable of grinding fine enough for espresso. Its stepless adjustment allows you to dial in precisely for any coffee.
Is the Rocket Macinatore good for single dosing?
Yes, the Rocket Macinatore is designed for single dosing. With only 0.8g of retention, virtually all the coffee you put in comes out ground. Weigh your beans before grinding for the most consistent results.
Why choose flat burrs in the Rocket Macinatore?
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 Rocket Macinatore?
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 Rocket Macinatore worth $750?
The grinder is the most important variable in espresso quality — more important than the machine. Investing in a quality grinder like the Rocket Macinatore 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.
