What It Pairs Well With
The GB5 S is a commercial 2-group machine designed for high-volume café use. It pairs best with commercial-grade grinders:
- Mahlkönig E65W Grind-by-Sync — La Marzocco's official partner grinder for the GB5 series; integrates via WiFi to auto-adjust grind based on shot time feedback from the machine
- Mahlkönig E65S GbW — the standard high-performance commercial pairing for GB5 installations without the Sync system
- Nuova Simonelli Mythos — a strong alternative at the commercial tier
Our showroom's Eureka Atom 75 demonstrates the GB5 S at the grinder performance level we carry. Our team can advise on commercial grinder sourcing for café and multi-group installations — book an appointment.
