PRECISE TECHNIQUE

The grinding process involves reducing the freshly roasted coffee bean to a powder using a grinder. Grinding has to be extremely accurate since it affects both the coffee flow time and the various tasting criteria.

After roasting, the coffee is transferred to an air-locked silo to prevent oxidation.

• On contact with oxygen, the quality of the roasted and ground coffee deteriorates; it loses its aromas more quickly as the area in contact with oxygen is increased after grinding.

The coffee is placed into a grinder. The level of grinding is calculated to suit the particular blend of coffee origins.

• The grinding of the coffee beans particularly affects the flow time when preparing your coffee.
• The more finely ground the coffee, the slower the speed with which water will pass through it, and the more full bodied and bitter the taste will be.

Accurate and consistent grinding is key to perfect coffee quality, cup after cup.

•  Nespresso's know-how is again demonstrated by the accuracy required for this operation.
• It is a question of finding just the right balance of the various attributes that we wish to bring out in each Premium Blend: acidity, bitterness, body and aromatic notes.
• When preparing an espresso, the coffee's exposure to hot water is relatively short. This is why the grind must be fine to release the aromas quickly.
