- The cherries are pulped to remove the outer skin, then fermented in water to separate the mucilage from the beans.
This method typically results in a cleaner, brighter flavor profile. It’s popular in countries like Colombia and Ethiopia.
Dry (or Natural) Processing:
- Cherries are dried in the sun before the outer skin is removed, allowing the beans to absorb the sugars from the fruit.
- This can lead to a fuller body and sweeter flavor, often found in coffees from Brazil and Yemen.
The choice of processing method is crucial since it directly affects the coffee’s acidity, aroma, and overall taste.
Selecting the Best Coffee Beans
When it comes to choosing quality coffee beans, there are several aspects to keep in mind.
1. Bean Appearance
A good coffee bean exhibits certain visual characteristics:
Size and Shape: Quality beans are uniform in size and shape. Arabica beans are typically oval with a curved crease, while Robusta beans are rounder.
