LUCCA's goal was to enhance the precision of flow control in manual devices across the industry to enable better extraction management. They aimed to integrate advanced flow control into top-tier E61 models. They engineered a tool designed to optimize your coffee's extraction, unlocking maximum flavor with a user-friendly interface for managing your brewing profiles. This innovative accessory is designed to fit any E61 espresso machine, providing baristas the flexibility to fine-tune each espresso shot by modifying the water flow and pressure right at the group head, with settings ranging from 0 to 10 bar.
