Rocket Giannino Burr Pair 55 mm – Original 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 direct comparison.
The Giannino is built for precision, with stepless adjustment and programmable doses – qualities that are only ever as good as the sharpness of the burrs that actually shape the grind.
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 more unpredictable, no matter how carefully dosing and tamping pressure are otherwise dialled in. A fresh burr pair brings the Giannino's precision back to its starting point.
The original burrs from Rocket Espresso are made exactly for the Giannino, with a 55 mm diameter designed for espresso grinding.

Frequently asked questions
How often should the Giannino's burrs be replaced?
That depends a lot on how intensively you use it and on the bean variety. A clearly more irregular grind or noticeably more fines compared to before are the most reliable signs, not a fixed time period.
How can you tell if the burrs are worn?
A more irregular grind, more fines, or a noticeably different taste despite the same setting are the clearest signs.
Can I change them myself?
Replacing the burrs requires opening the grinding chamber. 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.
How quickly will the burrs arrive?
Delivery takes 2–4 business days, throughout Switzerland and to Liechtenstein.
The roastery tip
Freshly sharpened burrs deserve beans that show off that precision. 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.
