Mandarin is a small evergreen tree with a single trunk and many thin, drooping branches. Often confused with Tangerine, the Mandarin orange is a variety in the same Rutacae family. Mandarin fruit peels are used to make three different Mandarin essential oils. The oil produced depends on the ripeness of the fruit. Green Mandarin comes from early fruit that is still green, Red Mandarin comes from completely ripened fruit, and Yellow Mandarin comes from fruit in the middle of the ripening stage. Yellow Mandarin oil from cold pressed semi-ripe fruit peel is the most floral of all mandarin oils. It has a positively delicious and uplifting aroma.
