Rocket Giannino – Espresso Grinder with 55mm Steel Burrs
Beans in, gently turn the large adjustment wheel, and the grind slides steplessly into the espresso range. The Giannino is a compact grinder for home use – slim-built, with a touch display and a hands-free portafilter holder that grinds directly into the portafilter.

55mm Steel Burrs
The steel burrs grind evenly for espresso. Particle size and consistency determine how clean the extraction runs – the basis for a balanced shot.
Stepless Grind Adjustment
You can steplessly adjust the grind using the large adjustment wheel – fine enough for espresso, with fine gradations for precise tuning.
Touch Display and Dosing
Three programmable doses plus continuous mode, controlled via a touch display. The hands-free portafilter holder grinds directly into the portafilter.

What Goes With It
The Giannino pairs well with Rocket portafilter machines from our Rocket Collection. For clean puck prep, you'll find tampers and distributors in the Tamper Collection, and for weighing doses, a Normcore scale or an Acaia scale can help.
