Bergamot is a type of bitter orange with greenish-yellow skin. Its pulp is too sour to eat, so the fruit is produced solely for the extraction of the essential oil from the peel. It is not possible to grow bergamot trees from seed. Instead, young shoots are grafted onto rootstock of other species, such as bitter orange or lemon, to propagate new trees.
This oil has a delightful aroma: fresh and young with strong citrus notes, and a sweetness as it evaporates.
