Magister Stella Dual Boiler Semi-Automatic Espresso Machine

The Magister Stella is the result of years of refinement and research by Magister, a company that has been producing espresso equipment since 1997. Originally known for their durable HX (heat exchanger) machines, Magister responded to growing demand for a prosumer dual boiler system—introducing the Stella line after extensive R&D. Built with premium materials and designed for both performance and reliability, the Stella brings café-quality espresso into the home or small commercial environment.

A key design choice is the use of copper boilers, preferred for their superior heat conductivity and stability compared to stainless steel. Paired with a rotary vane pump—quieter and more durable than vibration pumps—the Stella provides a smooth and enjoyable brewing experience, whether using the internal water tank or plumbing it directly to a water line.

Key Features

Dual Boiler System

• Copper Boilers with Insulation – Superior heat retention ensures exceptional thermal stability. (Note: copper boilers are more prone to limescale, so a water softener is strongly recommended.)

• Brew & Steam Simultaneously – No wait time when switching between espresso extraction and milk steaming.

• Auto-Shutoff Protection – Sensors monitor boiler water levels, shutting off the heating element when too low to prevent damage.

4-Key OLED Display

• Programmable Espresso Dispensing – Choose preset volumes or use manual start/stop with real-time shot volume display.

• Adjustable Boiler Temperatures – Independent settings for both brew and steam boilers, including ECO mode.

• Boiler Priority – Select which boiler heats first during startup or refill.

• Celsius/Fahrenheit Toggle – Easy switching between units.

• Shot Timer (Chrono Function) – Precise extraction monitoring.

• Usage Counters – Track shot count and overall machine use.

• Maintenance Reminders – Optional alerts for cleaning or water softener replacement.

• ECO Mode – Automatically reduces power consumption after a preset idle time (up to 30 minutes).

E61 Grouphead
