Liberica beans are primarily grown in the Philippines, although their cultivation spreads to other countries.

Origins of Coffee Beans

Coffee beans are grown in various regions worldwide, with each region producing unique flavors and characteristics. Some of the most common regions for coffee bean cultivation include:

South America

South American nations like Colombia, Brazil, & Peru are renowned for their production of premium Arabica coffee beans. These beans have a milder flavor profile than their African counterparts and are often used to create specialty coffee blends.

Processing Coffee Beans

The process of coffee bean processing varies depending on the region and the type of bean. However, there are two primary methods of coffee bean processing:

The process of roasting coffee beans is essential in determining the final flavor profile of the coffee. There are three primary roast levels:

Light Roast

Medium Roast

Coffee beans are considered medium-roasted when their roasting time is between that of a light roast and a dark roast. These beans are superior for espresso mixes because of their stronger taste and deeper color.
