XLVI STH9 1 Group Black — Compact Dual Boiler Italian Espresso Machine

Overview

The XLVI STH9 1 Group in matt black is a striking custom finish of XLVI's professional yet compact Italian espresso machine — finished entirely in deep matt black across the body, side discs and even the iconic XLVI roman-numeral-cut feet plate, with subtle stainless steel trim and brass-toned saturated group accents creating a bold, monochromatic statement piece. Hand-built by XLVI to deliver precise temperature control, excellent thermal stability and high energy efficiency, this all-black STH9 brings the engineering and quality standards of XLVI's full-sized commercial machines into a footprint that suits specialty cafés, small bars and the most demanding home setups alike.

At its heart is a 7.5kg saturated brass group head paired with a PID temperature control system and XLVI's proprietary preheating system that optimises both espresso delivery and steam production. The internal rotary pump(100 L/hour) provides whisper-quiet, professional-grade pressure, while a 3L service boiler ensures powerful, consistent steam. Distinctive design highlights include XLVI's Smooth Flow extraction for velvety, even espresso, adjustable mechanical and electronic pre-infusion, U Can Touch cool-touch steam wands, and signature circular black side discs that frame the machine's bold silhouette. With dual heating modes (combined or alternated), dual water connection options (tank or mains), an OLED display, automatic washing, and full customisation in colours, materials and accessories, the STH9 1 Group Black is a true expression of XLVI's artisan Italian craftsmanship.
