Oranges are classified as a citrus scent, and the fragrance extracted by squeezing the fruit and peel is used in both flavors and fragrances. There are varieties such as sweet oranges, which are characterized by their strong sweetness, and bitter oranges, which have a slightly bitter taste, but their sweetness is highly compatible with fruity notes, and they are frequently used in not only citrus-type perfumes but also fruity-type perfumes. As introduced on the petitgrain page, petitgrain is made from the branches and leaves of bitter oranges, and neroli is made from the flowers, making it a unique plant in which fragrances can be extracted from the fruit, flowers, and leaves.
