Know before you buy
The Minima is currently the smallest dual boiler machine on the market. Despite its compact footprint, it retains professional-grade stainless steel boilers and an E61 group head, making it ideal for home baristas with limited counter space who don't want to sacrifice performance.
Yes. Because it features a dedicated dual boiler system, you can pull your espresso shot and steam your milk simultaneously without any loss in pressure or temperature stability.
The PID controller allows you to set and maintain precise water temperatures for your brew boiler. This ensures consistency across different coffee roasts and helps you avoid the temperature fluctuations common in traditional heat-exchanger machines.
The LSP (Level Steam Protection) system is a safety feature that prevents the machine from interrupting your shot if the water level in the steam boiler drops. It ensures your brewing process remains uninterrupted even during heavy use.
No, the ACS Minima does not include a built-in pre-infusion function. It is designed as a straightforward, manual-control machine that relies on the user to manage the extraction process.
The machine features a removable 2.6-liter water tank, which is quite generous for its size. You can easily lift it out for cleaning or refilling at the sink.
