How often should an espresso machine be calibrated, and why?

Anima checks calibration at every weekly technician visit — grinder burr wear, water temperature and extraction pressure — plus the water filtration and descaling included with every rental. Regular calibration keeps extraction consistent, protects the boiler from scale buildup, and prevents the flavour drift that creeps in between visits. It's covered by your service plan, with no separate line item. Compare machines →
