As the name might suggest, the citrus family of fragrances includes such notes as bergamot, lemon, orange, tangerine and grapefruit. Typically, other parts of the orange tree (petit grain, orange blossoms, and/or neroli oil) are added, which lend a slightly exotic feel.
Words used to describe these types of refreshing fragrances are: fresh, light, tangy, crisp, sharp, energizing, and uplifting. Loved by both men and women alike, notes of florals or chypres are often mixed in for complementary effects.
One of the oldest classifications of aromas, the first Eau de Cologne was a spirit-citrus perfume developed by an Italian perfumer in Cologne, Germany in 1709. A classic example of a citrus aroma in modern times is Mugler Cologne ($48 to $68), a unisex fragrance that has notes of bergamot, orange blossom, neroli, petit grain, green sap, and white musk.
