What taste is associated with an overdose of espresso?

The taste associated with an overdose of espresso is typically described as too bitter and strong. When espresso is brewed improperly, such as through over-extraction, the excessive bitterness can dominate the flavor profile. This occurs because the prolonged contact of water with the coffee grounds extracts not only the desired soluble compounds but also undesirable bitter components. As a result, the experience can be unpleasant, overshadowing any sweet or balanced flavors that the espresso might otherwise possess.

In contrast, the other options depict characteristics of espresso that arise from ideal brewing practices. For example, sweet and creamy flavors suggest a well-extracted espresso that maintains a harmonious balance of sweetness and body. Balanced and smooth indicates a perfect extraction where the taste avoids excessive bitterness or sourness. Watery and weak reflects a scenario where under-extraction has occurred, leading to a diluted and less flavorful cup, which is distinct from the intensity and bitterness tied to an overdose of espresso.
