Rocket Giannino Burr Set 55 mm – Genuine Spare Part
Every bean that passes through the Giannino's burrs leaves a barely visible trace – over many shots, the cutting edges of the 55 mm steel burrs lose their sharpness, and the grind changes, often gradually enough that you only notice it in a direct comparison.
The Giannino is built for precision, with stepless adjustment and programmable doses – qualities that are only as good as the sharpness of the burrs actually shaping the grounds.
Why sharp edges make the difference
Particle size and consistency largely determine extraction quality. Worn burrs produce more fines and a less even grind, which makes extraction less predictable, no matter how carefully dosing and tamping pressure are otherwise dialled in. A fresh pair of burrs brings the Giannino's precision back to its starting point.
The original burrs from Rocket Espresso are made specifically for the Giannino, with a 55 mm diameter designed for espresso.

Frequently asked questions
How often should the Giannino's burrs be replaced?
That depends heavily on how much you use it and the type of bean. A noticeably less even grind or a clear rise in fines compared to before are the most reliable signs, not a fixed timeframe.
How can you tell burrs are worn?
A less even grind, more fines, or a noticeably different taste despite the same setting are the clearest signals.
Can I replace it myself?
Replacing the burrs means opening up the grinder. If you're unsure, our team is happy to help.
Can I see the product before buying?
Yes, in our showrooms in Bern (Gerberngasse 44) and Zürich (Hagenholzstrasse 50b) you can see the original spare part in person.
The roastery tip
Freshly sharpened burrs deserve beans that show off that precision too. Our main recommendation: Cozy Chocolate and Nutty Delight, dense, aromatic, full-bodied. For maximum body with no acidity at all: Very Nutty. For anyone who wants to discover a fruity experience: Wild Peach, vivid and always a discovery. Our recommendation from the roastery, one of many.
