LEVER-EXTRACTED ESPRESSO IS UNMISTAKEABLE.

IT TELLS A UNIQUE STORY.

LEVER- EXTRACTED ESPRESSO.

IS THE TRUE ESPRESSO.

With the invention of lever-driven coffee machines, a great Italian tradition was born: espresso. A unique coffee, appreciated worldwide for its aroma, flavour and creaminess. A captivating and timeless ritual.

THE BARISTA.
SKILL, TECHNIQUE, PASSION.

Lever-pressed espresso is unique due to the barista's attention, dedication and precision. Every single cup is the fruit of the barista's skill in adapting each stage of the extraction process according to the blend and to the drinker's preferences.
The lever puts the barista centre-stage, calling upon him or her to bring out all that the coffee has to offer and to tell.

HOW TO ENJOY EXCELLENCE.

The time has come to stop for a moment, to dedicate that extra minute to ourselves. Because when the coffee machine is lever-driven, the tasting experience is something altogether different. An espresso to be discovered sip by sip, it will not easily be forgotten. A coffee that tells a story, and once savoured, leaves a sweet and lasting memory on the tongue.

LEVER-DRIVEN MACHINES.
FOR SUPERLATIVE COFFEE EXTRACTION.

Initiation

Pre-infusion

Percolation of the coffee powders is completed. The barista decides the duration of the pre-infusion (3-5 seconds), which ends when the lever is released.

Delivery

Finish

LEVER VS AUTOMATIC.
TWO DIFFERENT EXTRACTION SYSTEMS

What makes the lever-driven system truly unique are the two main elements of the extraction process: the water temperature and the pressure profile.
Water is drawn directly from the boiler, and after a short pre-infusion time it is pushed by lever controlled, spring-operated piston through the coffee powder at variable pressure, starting from a much higher value compared to electronic machines, to extract the most noble flavour notes and generate a thick cream, then gradually decreasing up to the cut-off point which is controlled by the skilled barista.

COMPARISON OF PRESSURE CURVES

Unlike the electronic extraction system, in the lever-driven system, the extraction pressure is not constant:

  1. It begins gently, as the first drops of hot water gradually reach the coffee filter.
  2. It peaks at 12/14 bar as pre-infusion begins.
  3. During delivery, it gradually drops back down to 6 bar.
  4. During the finish, it falls from 6 to 0 bar in a matter of seconds. 

IN THE CUP.
ONLY THE BEST OF COFFEE.

 

CREAMY

The hot temperature and high pressure combine to activate an emulsion process that gives a perfect espresso: thick, creamy and velvety.

FRAGRANT

Lever-pressed coffee passes through a fine mesh and shower, which enables it to retain its aroma and all the fragrance of the coffee extract for longer.

FULL-BODIED

The lever extraction system gives a higher concentration of coffee particles dissolved in the water, making for a full-bodied and beautifully structured espresso.

DELICATE

Thanks to the rapid drop in pressure during the final phase, the unpleasant bitter notes from the over-extracted coffee grounds do not reach your cup. What you are left with is the pure nectar of a real espresso coffee.
