Citrus bergamia, the bergamot orange, is a fragrant citrus fruit the size of an orange, with a yellow or green colour similar to a lime, depending on ripeness.
Genetic research into the ancestral origins of extant citrus cultivars found bergamot orange to be a probable hybrid of lemon and bitter orange. Extracts have been used to scent food, perfumes, and cosmetics. Use on the skin can increase photosensitivity, resulting in greater damage from sun exposure.
Citrus bergamia is a small tree that blossoms during the winter. The juice tastes less sour than lemon, but more bitter than grapefruit.
Production is mostly limited to the Ionian Sea coastal areas of the province of Reggio di Calabria in Italy, to such an extent that it is a symbol of the entire city. Most of the bergamot comes from a short stretch of land there, where the temperature is favourable. The fruit is also produced in Argentina, Brazil, Algeria, the Ivory Coast, Morocco, Tunisia, Turkey, and South-East Asia where it has its roots.
Citrus bergamot is commercially grown in southern Calabria (province of Reggio), southern Italy. It is also grown in southern France and the Ivory Coast for the essential oil and in Antalya in southern Turkey for its marmalade. The fruit is not generally grown for juice consumption. However, in Mauritius where it is grown on a small-scale basis, it is largely consumed as juice by the locals.
