The primary difference between Rose otto and Rose absolute lies in their extraction methods. Rose absolute is solvent-extracted, which means that chemical solvents are used to extract the aromatic compounds from the rose petals. This method allows for a higher yield of the fragrant components but may also incorporate some soluble plant materials that are not always present in essential oils.

In contrast, Rose otto is typically produced through steam distillation, a method that does not employ solvents and thus results in a purer product with only the essential oil components. The steam distillation process can yield a lower quantity of oil, which is often why Rose otto is more expensive than Rose absolute.

Understanding the extraction methods provides insights into the final product's quality and characteristics, including aroma complexity and therapeutic properties. This clarifies the importance of recognizing how the extraction process impacts the essence and application of essential oils in aromatherapy.
