What are the middle notes in essential oils primarily associated with?

The middle notes in essential oils are primarily associated with filling the gap in aroma profiles. They serve as the bridge between the top notes, which are more volatile and provide an initial impression, and the base notes, which linger longer and provide depth to the scent. Middle notes typically emerge once the top notes dissipate and help create a balanced fragrance composition.

These notes often include scents that are more rounded and fuller, such as floral, herbaceous, and certain spicy aromas. By filling the gap in aroma profiles, middle notes contribute significantly to the overall depth and richness of the blend, making them essential for creating a well-rounded aromatic experience. Other choices, while related to aspects of fragrance, do not accurately describe the core function of middle notes in essential oil blends.
