Diletta Alto Espresso Machine

The dual boiler system allows you to brew espresso and steam milk simultaneously without any loss of temperature stability. This is essential for maintaining consistent pressure and heat, ensuring you can craft multiple drinks back-to-back without waiting for the machine to recover.

The flow control valve allows you to manually adjust the water flow rate during your shot. By restricting or increasing the flow, you can experiment with different pressure profiles, which helps highlight specific flavor notes in lighter roasts or rescue shots that might otherwise channel.

Yes, the PID controller allows you to set the boiler temperature with degree-specific accuracy. This is particularly useful if you frequently switch between different coffee origins or roast levels that require precise temperature adjustments to taste their best.

The Over Pressure Valve (OPV) regulates the maximum pressure applied to the coffee puck during extraction. Having an adjustable OPV allows you to fine-tune your machine to your preferred pressure, typically set to the industry standard of 9 bars, ensuring optimal extraction quality.

The machine measures 19.75 inches deep, 12 inches wide, and 14.5 inches high. Given its 40-pound weight and depth, ensure your counter is sturdy and has enough clearance for both the machine and the necessary workflow space for your grinder and accessories.

The eco-mode is designed to reduce power consumption when the machine is idle for extended periods. While it saves energy, keep in mind that the machine will need a short amount of time to return to full operating temperature once it wakes from this low-power state.
