Scent Description
Bergamot presents a uniquely sophisticated citrus profile that sets it apart from other citrus oils. The opening is bright and sparkling with fresh lemon-like facets, quickly revealing subtle floral undertones reminiscent of lavender and neroli.

Historical Context & Cultural Significance
Ancient Origins
Bergamot cultivation began in Calabria, Italy, possibly as early as the 14th century. The fruit is believed to be a natural hybrid between bitter orange and lemon, first documented in Italian literature in the late 1600s.
Perfumery Adoption
The essential oil entered perfumery in the early 18th century, becoming a cornerstone of cologne formulations. Its inclusion in the original Eau de Cologne formula (1709) established its reputation as the sophisticated citrus note.
Earl Grey Connection
The association with Earl Grey tea (1830s) elevated bergamot to iconic status. This cultural connection created a sophisticated, aristocratic image that perfumers have leveraged for nearly two centuries.
Modern Monopoly
Calabria produces 95% of the world's bergamot, with the narrow coastal strip between Villa San Giovanni and Gioiosa Jonica providing ideal growing conditions. The region's unique terroir cannot be replicated elsewhere.
