The Dual Boiler™ is for the coffee connoisseur who prefers to control every step in the … The Dual Boiler is the professional Barista’s choice for their home machine.
Espresso perfection requires precision temperature and pressure control, consistently, every time, and the Sage by Heston Blumenthal Dual Boiler™ espresso coffee machine will deliver just that. It features dedicated stainless steel boilers for steam and espresso, allowing simultaneous milk texturing and extraction consistently at 93⁰C.
The Dual Boiler features an Over Pressure Valve. This commercial feature limits the maximum pressure throughout the extraction, preventing bitter flavours in the shot.
It also offers a true low pressure pre-infusion, which gradually increases the pressure to gently expand the grinds for an even extraction, for a smoother taste.
The brew temperature, pre-infusion pressure and duration are all programmable.
