Ascaso Steel UNO PID Espresso Machine

The thermoblock system heats water on demand as it passes through the machine, which allows for a much faster startup time compared to a traditional boiler. Because it only heats the water you use, it is also more energy-efficient and less prone to limescale buildup.

Yes, the machine features an externally adjustable over-pressure valve (OPV). This allows you to fine-tune the extraction pressure to suit different coffee roasts and grind sizes without needing to open the machine casing.

Yes, the Ascaso Steel UNO does not have a built-in grinder. You will need to purchase a separate burr grinder to achieve the consistent, fine grind necessary for espresso extraction.

Volumetric programming allows you to set a specific water volume for your shots, ensuring consistency every time you brew. Once programmed, you can start your shot and the machine will automatically stop at your desired yield, so you don't have to manually time or weigh every extraction.

The steam wand is designed to be 'no-burn,' meaning the exterior stays cool to the touch, which prevents milk from baking onto the wand. Simply wipe it down with a damp cloth immediately after steaming to keep it clean.

Yes, the machine includes a pre-infusion feature. This briefly saturates the coffee puck with water before applying full pressure, which helps to reduce channeling and promotes a more even, balanced extraction.
