What flavor profile is described as "Heart" in espresso?

In espresso tasting terminology, the "Heart" flavor profile is associated with sweetness and a medium body. This refers to the core flavors that are most prominent in a well-extracted espresso shot. A sweet flavor profile typically indicates a balance of acidity and sugar present in the coffee, contributing to a pleasant and smooth taste experience. The medium body signifies a richness that complements the sweetness, creating a harmonious profile that is characteristic of quality espresso.

This understanding is foundational for baristas, as recognizing and describing these flavors helps in crafting espresso beverages that meet customer preferences. Sweetness in espresso can come from various factors such as the type of coffee bean, the roasting process, and the brewing method, all of which influence the final cup.
