Rancilio Classe 5 ST Commercial Espresso MachineAn ideal espresso machine for catering, mobile cafes and farmer's markets, the Rancilio Classe 5 ST improves on the Epoca's case design while offering quick heat steam, temp stable shots and a spacious two liter reservoir. The Classe 5's small size doesn't sacrifice usability either, thanks to its ergonomic portafilter and steam knob controls. And with a single, semi automatic brew button, operation couldn't be any easier!
