Collection: Saturated Group Espresso Machines

In saturated group head espresso machines, water is heated directly in the group head to maintain a stable temperature while brewing. This design differs from other group heads like E61 or semi-saturated types, which use separate water channels or thermosyphon systems.

The saturated group head functions as part of the coffee boiler, keeping its metal components consistently hot for precise espresso extraction control. This direct water heating system offers more accurate temperature regulation, resulting in consistent espresso quality.
