How will this change espresso?

Coffee Roasted for Espresso

The roast of the coffee dictates the brew method


Traditional Mentality Coffee roasted for an espresso

machine

New Mentality The espresso machine is

adaptable for any roast of coffee.


We set out to…


Create a machine that allows the

barista to extract espresso that

reflects the characteristics found

when cupping a coffee.

A machine that puts control of all

espresso extraction variables at

the baristas finger tips.

A machine that works.

Pressure Summit February 2011

The Goal To find a unified, barista-approved

methodology for pressure profiling.

Hypothesis: One pressure profile would be found

that would make the flavor of the espresso match the flavors experienced

while cupping the same coffee.


18 grams of coffee 30-35 grams extracted Temperature of 201*

Extraction time of 30 seconds

Pressure was the only variable changed in process.




Pressure was the only variable changed in process.


What was different between the various coffees?

In Italy: Coffee was lightly roasted

Medium & Dark Roast Levels •Coffee is roasted further •Less organic matter •Broken down cellular structure •Coffee has less density

What if we simply peek at less pressure?




Single-Estate, Medium Roast, Medium Density




Darker roasts, lower altitude, lowest density coffees




What about coffee roasted for espresso or blends?


Secondary Goals Less down time

Lower failure rate

Easier to maintain & repair

Mechanical Parts

Moving parts

Wear and tear

Break down

Electronic Parts

Less movement

Lower failure rates

Last longer
