How to transform beans and reuse wastes

Coffee Life Cycle

Grinding coffee

You should always grind your coffee beans just before brewing it. It can be convenient to grind a large batch of beans, but oxydation will be faster with ground coffee beans. Weight your beans and grind what you are going to consume, nothing more, nothing less.

Reuse wastes

coffee vocabulary

  • Extraction: Dissolving coffee solubles into water. Just like tea infusion.
  • Degassing: Once beans are roasted, CO2 forms inside beans and begin to leave them. A few days of degassing is necessary before grinding coffee beans.
  • Oxydation: Solubles degradation by oxygen. Oxydation gives coffee a stale taste because soluble compounds of interest are degraded. Beans should be sealed as soon as possible.
