Bergamot is a citrus fruit grown almost exclusively in a tiny coastal strip of southern Italy. Around 90% of the world’s bergamot comes from fewer than 1,400 hectares in Calabria, the region at the “toe” of the Italian boot. The fruit is a natural hybrid, most likely a cross between sour orange and lemon, and it thrives in a microclimate so specific that centuries of attempts to grow it elsewhere have mostly failed.
A Hybrid Citrus With Debated Parents
Bergamot belongs to the citrus family and produces round yellow fruits on trees with large, dark green oval leaves and star-shaped white flowers. Genetically, it’s defined as a hybrid between sour orange and lemon, though some researchers believe lime rather than lemon was the second parent. A third theory holds that bergamot is simply a mutation of lemon rather than a true hybrid. What everyone agrees on is that it’s a distinct variety, formally recognized as its own citrus species since at least 1818.
Why Calabria Dominates Production
The narrow coastal plain along the southern tip of Calabria, near the city of Reggio Calabria, provides a combination of mild winters, warm summers, and specific soil conditions that bergamot trees need. Citrus in general is cold-sensitive and can die back after extended exposure to temperatures near or below freezing. Bergamot is particularly finicky: it demands well-drained soil, consistent warmth, and the kind of humidity that this sliver of Mediterranean coastline delivers naturally.
The first commercial bergamot orchard in Calabria was established in 1750, and the region quickly expanded production to feed growing demand from European perfumers. Today, that same small area still accounts for roughly 90% of the world’s supply of bergamot essential oil.
Other Countries That Grow Bergamot
The only other commercially significant producer is the Ivory Coast, which contributes about 8 to 10% of the global bergamot oil market. Several South American countries, including Argentina, Brazil, and Uruguay, have grown bergamot since the 1960s, but their output remains modest. China has also entered the picture more recently. Despite these efforts, no region has come close to matching Calabria’s dominance, partly because the fruit’s quality and oil composition seem tied to that specific microclimate.
How Bergamot Got Its Name
The word “bergamot” has two competing origin stories. One traces it to the Turkish word “beg-a-mudi,” meaning “pears of the prince,” because the fruit resembles a variety of bergamot pear. The other links it to the Italian city of Bergamo, where bergamot oil was reportedly sold for the first time. Both explanations have been circulating since at least the late 1600s, and neither has been definitively proven.
There’s also a popular legend that Christopher Columbus picked up bergamot in the Canary Islands and brought it to Spain, from which it supposedly traveled to Calabria around 1500 and was grafted onto a lemon tree in a count’s garden. Regardless of how it arrived, the first written record of bergamot in Europe dates to 1693, and its cultivation wasn’t documented until the mid-1700s. It was one of the last citrus species to appear in European art or historical records.
What Bergamot Is Used For
If you’ve had Earl Grey tea, you’ve tasted bergamot. The fruit’s essential oil gives the tea its distinctive floral, slightly bitter flavor. But the perfume industry was actually the original driver of bergamot demand. When “Eau de Cologne” became fashionable in 18th-century Europe, bergamot oil was a key ingredient, and Calabrian orchards expanded rapidly to keep up.
The oil is extracted primarily from the fruit’s peel using cold-pressing methods, which keep temperatures low enough to preserve the oil’s complex aromatic compounds. Traditional Calabrian producers used a hand-pressing technique called “sfumatura,” in which the peel was squeezed against a sponge to release the oil. Modern production relies on mechanical cold-pressing equipment, but the principle is the same: pressure rather than heat does the work.
Bergamot fruit itself is too sour and bitter to eat raw, which is why most people encounter it only as an oil or flavoring. The juice has found some use in local Calabrian cooking and, more recently, in supplements studied for their effects on cholesterol and blood sugar. But the essential oil, with its bright, complex scent that sits somewhere between lemon and orange blossom, remains bergamot’s primary claim to fame.
