The LUCCA M58 Sunto with Flow Control is the end-game dual-boiler, rotary-pump espresso machine, built exclusively for Clive by Quick Mill in Milan. Super compact for an E61 dual-boiler in its class, it combines E61 brewing precision with modern dual-boiler performance, wrapped in minimalist stainless steel or a sleek matte-black finish, both outfitted with walnut trim. With a built-in OLED PID controller, shot timer, programmable pre-infusion, flow control, a group head heating element that gets you up to brew temperature 40% faster than standard E61 machines, and the choice to plumb directly or run on its internal reservoir. The M58 Sunto with Flow Control is designed for the home barista who wants commercial capability without the complexity. This is the machine Clive's team reaches for when they want to dial in a new single origin or pull back-to-back drinks for a crowd. Key Features Dual Boiler System: Separate 0.75L brew boiler and 1.5L steam boiler with independent PID control. Brew and steam simultaneously without temperature compromise. Flow Control: Our LUCCA E61 Stainless Steel Flow Control system is pre-installed for your convenience and is the ultimate tool for tailoring your shots to your taste. Compact Profile: We made a mighty effort to make the M58 Sunto with Flow Control one of the most powerful and compact dual-boilers in its class. Smaller than the original M58 and many traditional E61 dual-boilers, without sacrificing an ounce of performance or counter space. E61 Group Head: The standard for espresso temperature precision since 1961. Instant Stability: A dedicated heating element in the group head brings the M58 Sunto with Flow Control to full brewing temperature in just 12 minutes, which is 40% faster than standard E61 machines. Flow Control Device: Pre-installed paddle on the E61 group head. Adjust flow rate and pressure during extraction to unlock new flavor profiles and rescue challenging beans. Rotary Pump: Whisper-quiet operation and stable, adjustable pressure. Unlike vibratory pumps, the rotary pump won't wake the household during your 6 a.m. shot. OLED PID with Shot Timer: Navy-blue PID display with 0.1°C accuracy. Integrated shot timer tracks extraction in real time. Switchable Water Supply: Plumb directly to your water line or run on the built-in 3L reservoir. A braided water line is required for plumbed operation and sold separately here. Joystick Steam & Water Controls: Smooth, single-motion control for steam and hot water. More precise than traditional knobs, easier to clean. Walnut Bottomless Portafilter Included: Ships with a Clive-made walnut bottomless 58mm portafilter so you can watch channeling, dial in faster, and pull more beautiful shots. 1400W Heating Elements: From cold start to pulling a shot and steaming 12oz of milk, the M58 Sunto with Flow Control recovers to target temperature in under 60 seconds.
