Flavor or flavour is the sensory impression of a foods, drinks, or other substances, and is determined mainly by the chemical senses of taste and smell. The “trigeminal senses”, which detect chemical irritants in the mouth and throat as well as temperature and texture, are also very important to the overall Gestalt of flavor perception. The flavor of the food, as such, can be altered with natural or artificial flavorants, which affect these senses.
Coffee beans that are grown in South America typically have a darker and fuller flavor with notes of chocolate, nut and caramel.
Beans that are grown in Africa usually have a brighter, acidic and fruity flavor.
Finally, the species of coffee also influences the flavor of the coffee in your cup. Arabica coffee would be considered to be milder and more balanced than Robusta coffee, which is often bolder and more bitter.
