The Alex Duetto is a dual-boiler, semi-automatic espresso machine designed for home baristas seeking precise temperature control and consistent shot quality. Dual boilers allow simultaneous brewing and steaming, while the E61 group head ensures even heat distribution. This type of machine typically features a PID controller for accurate temperature management and often includes a rotary pump for consistent water pressure.
This level of control offers significant advantages over single-boiler or thermoblock machines. Precise temperature stability contributes to optimal extraction, resulting in a more flavorful and balanced espresso. The ability to steam milk simultaneously streamlines the workflow, allowing for quicker preparation of multiple beverages. These features are often sought after by enthusiasts who value a professional-grade experience at home. The design and functionality often draw inspiration from commercial espresso machines, reflecting a heritage of Italian espresso culture.
