Overview
The ACS Minima is a remarkable feat of engineering — a true dual boiler espresso machine packed into one of the most compact form factors available. ACS (Avvicinamento Caffeespresso Selezionato) designed the Minima specifically for home baristas who want dual boiler convenience without the massive footprint typical of E61 machines. The machine features two independently PID-controlled stainless steel boilers: a 220ml brew boiler for precise extraction temperature and a 750ml steam boiler for powerful, consistent steam. Despite its compact size, the Minima uses a full-sized E61 group head, maintaining compatibility with the enormous ecosystem of E61 accessories including flow control devices, precision shower screens, and aftermarket baskets. The pre-infusion capability allows for gentle puck saturation before ramping to full pressure, and the PID displays show real-time temperature for both boilers. The machine is remarkably space-efficient, measuring just 250mm wide — significantly narrower than most E61 dual boilers. The generous 2.5-liter water reservoir means less frequent refilling, and the built-in cup warmer keeps your cups warm between shots. For those who thought they did not have room for a proper E61 dual boiler, the ACS Minima changes the equation entirely.
The ACS Minima comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction. It features a dual boiler boiler system made of stainless steel with a 220 ml capacity. The vibratory pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $1,700, the ACS Minima is designed for dedicated prosumers who demand professional-grade equipment. The dual boiler design allows simultaneous brewing and steaming, making it ideal for milk-based drinks without any wait time.
In terms of build quality, the ACS Minima is a substantial machine, weighing in at 17.0 kg, manufactured in Italy, drawing 1400W of power. With dimensions of 250 x 400 x 380 mm (W×D×H), make sure you have adequate counter space. The built-in water reservoir holds 2500 ml, making it easy to set up anywhere in your kitchen.
