What is a primary component of coffee that influences its flavor?

The primary component of coffee that significantly influences its flavor is the oils released during brewing. During the brewing process, coffee beans release essential oils that contain a variety of compounds, contributing to the coffee's overall aroma and flavor profile. These oils are responsible for the richness and complexity of the coffee's taste, enhancing its mouthfeel and providing various flavor dimensions.

While the sugar content in coffee can also affect sweetness and balance, and water temperature plays a crucial role in extraction efficiency, it is the oils that hold a significant amount of flavor compounds, making them a primary factor in taste. Aromatic spices may complement coffee but are not inherent components of coffee itself. Therefore, understanding the role of oils in the brewing process helps to appreciate how they shape the final cup of coffee.
