Red mandarin essential oil is produced from the ripened fruit and peel of the 'Tangor' or mandarin tree. The difference between Green Mandarin and Red Mandarin is primarily based around the age of the fruit when it is harvested, Green Mandarin comes from younger and less-ripened fruit. Red Mandarin essential oil has a full body citrus aroma that is uniquely sweet and energizing, lending itself to many applications across the flavor and fragrance industry.
