about



Evello is a reimagined lever espresso machine designed from the ground up to make delicious espresso drinks crafted to your taste. Temperature adjustability and real-time brew pressure displayed on a touchscreen give you the ultimate control over brewing variables.


We are two mechanical engineers from Seattle who were frustrated with mediocre espresso produced by increasingly automated machines. Traditional lever machines though nice looking are difficult to learn and too inconsistent. We wanted a machine that allowed us to tweak every variable and see what was happening to the coffee during the brew process. After many prototypes, we arrived at a product that does just that. To finalize the design before production, we will need to make some design changes and complete relevant testing.



How it works



Once the machine is up to temperature, slowly lift the lever to its highest position and wait for the brew chamber to fill with water from the boiler (pre-infusion). After about 10 seconds, push the lever down with enough force to reach your desired brew pressure. You can instantly adjust the pressure (pressure profiling) by pushing more or less. The pressure can be viewed in dial or graph format. An "Advanced" mode will allow adjustments of all temperatures independently within given ranges. The novel group design allows two shots of espresso while minimizing trapped air.


Lever espresso machines are known for their reliability and longevity because they have fewer moving parts and are generally easier to service than pump machines. Our design only requires removal of one e-clip and four screws to gain access to all high-pressure seals and gaskets.



Prototypes



We are currently testing the two development-phase prototypes below.
