Start by carefully inspecting each bean, looking for any signs of dirt, stones, or other unwanted materials. Use your fingers or a small brush to remove any debris that you find gently.

Choosing the Right Water Temperature for Washing

First, start by determining the ideal water temperature for washing your green coffee beans. The water temperature plays a crucial role in the washing process as it affects the extraction of impurities and residues from the beans.

Here are some tips to help you choose the right water temperature:

  • Hot water: Using hot water (around 140°F or 60°C) can help dissolve oils and remove dirt effectively.
  • Warm water: A temperature of around 120°F (49°C) is suitable for most coffee beans, as it helps maintain the beans’ natural flavors.
  • Cold water: Cold water (around 50°F or 10°C) is recommended for delicate or light-roasted beans to preserve their delicate aromas.
  • Room temperature water: If you’re unsure about the best temperature, using room temperature water (around 68°F or 20°C) is a safe option.

Implementing the Proper Washing Technique

To properly wash your green coffee beans, ensure you agitate them gently in the water to remove any dirt or impurities.

Start by filling a clean container with lukewarm water, making sure it’s deep enough to fully submerge the beans.

Carefully pour the green coffee beans into the water, being cautious not to splash.

Use your hands to gently swirl the beans around in the water.
