What is the shape and color characteristic of Arabica coffee beans?

Arabica coffee beans are distinctively oblong in shape, which sets them apart from other types of coffee beans. Their color is often described as greenish-bluish before they are roasted. This specific coloration is due to the presence of certain chlorophyll pigments in the green beans. Once roasted, Arabica beans transform to a range of brown shades, but in their unroasted state, the greenish-blue appearance is a defining characteristic.

Understanding the characteristics of Arabica coffee is important for distinguishing it from other varieties, such as Robusta, which tend to be rounder and exhibit a different color profile. The shape and color contribute to the specific cultivation methods and quality characteristics of the coffee produced.
