Pourquoi la mouture de café est essentielle : extraction, fraîcheur et micrométrie

Why coffee grind is essential: extraction, freshness, and micrometry

☕ Grinding, the keystone of exceptional coffee

In the world of specialty coffee, every detail counts. And among them, the grind is one of the most crucial . It acts as a precision filter between the bean and the cup. If it's not right, it can compromise the entire sensory experience.


🎯 A grind adapted to each extraction method

Each infusion method requires a specific particle size :

  • Espresso : very fine grind

  • V60, classic filter : medium grind

  • Chemex : medium-coarse grind

  • French Press : coarse grind

  • Mocha : fine grind

  • Cold Brew : very coarse grind

The contact time between the water and the coffee, the temperature, the pressure: all these factors have an impact. A grind that is too fine results in over-extraction (bitterness), while a grind that is too coarse will produce a hollow, under-extracted cup.


🛠️ Micrometry: the art of precise adjustment

At our mill, we don't do things "approximately." We adjust our mills with micrometric precision , that is, to within a tenth of a millimeter. This level of detail is essential for adapting to:

  • for each coffee (origin, density, roasting),

  • for each extraction method,

  • to our specific paper filters ,

  • and to our preparation recipes developed for each batch.

In other words: each grind is custom-calibrated to reveal the best of each coffee.


🌱 Freshness above all: freshly ground

Even the finest grind loses all its appeal if it's a few days old. Ground coffee oxidizes rapidly , loses its volatile aromas, and its complexity disappears.

That's why we always recommend buying whole bean coffee , ground just before use. Grinding fresh at home with a good grinder is the only way to fully enjoy the aromas .

Yes, we offer custom grinding, tailored to your preferred method. But nothing replaces ultra-fresh grinding done just before extraction.


✅ In summary

  • The grind directly influences the extraction, and therefore the taste.

  • Each method requires a specific grind.

  • We adjust our grinds with micrometric precision according to the coffee, equipment and filters.

  • Nothing beats a freshly ground beer made at home.

  • Opt for whole bean coffee: it's a simple step for a much better cup of coffee.
