Most espresso machines carry quite complicated electromechanical systems but the ES3 uses a simple and robust lever mechanism. This technology—developed in post-war Italy—gives you absolute control over the extraction process.  The ES3 takes the art of coffee making back to its essential origin. The technology involved has been simplified and made visible in every detail. The machine is operated by hand and for full quality control you can rely on the judgement of your own senses. 
The ES3 uses the proven lever technique. With this technique a column of hot water is manually pressed through the coffee by means of a piston. It is a very clear procedure and it provides you the perfect espresso. 
Due to the open boiler design and removable piston, the technique is simple and makes it a low-maintenance machine. It uses electricity to heat the water and has an adjustable thermostat to set the water temperature.
