What is over-extraction?

Each Nespresso capsule is created to be extracted at a certain level. Past that, it will stop producing flavour and start to burn – meaning your coffee will taste bitter.

To help you extract at the recommended level every time, our coffee capsules have the recommended extraction size shown on the coffee sleeve.

Over-extraction can put excess pressure on your machine’s pump and may make it necessary for you to descale your machine more often. You may also find granules of coffee poured into your cup, which will affect the character profile of the blend.

We recommend descaling and using a new toothbrush on the pyramid plate to remove the build-up of coffee grinds.

For more information on maintenance, you can view guided videos on our Machine Assistance page.
