The Breville Dual Boiler is the home machine that coffee nerds respect despite the kitchen-appliance branding: dedicated boilers for brew and steam, rock-solid temperature stability and pre-infusion that rivals far more expensive machines.
It is the machine many smaller home setups "graduate" to — and the price is remarkable for a true dual boiler with PID control.
