Green notes play an intriguing role in the art of perfumery. Traditionally considered minor elements, they have gained increasing importance in fragrance compositions since the 1960s. Defining green notes precisely can be a matter of debate, as terms like fatty, herbal, and green elicit different interpretations. In the natural world, green is associated with vibrant, living vegetation—signifying health, freshness, and growth. In the realm of fragrances and essential oils, the green notes encapsulate these attributes, eliciting a perception of authenticity, diffusion and liveliness. 

Although green notes are not typically dominant components in natural oils, their presence in trace amounts can have a significant olfactory impact. They are known to add a sharp freshness and natural quality to various types of fragrances, including floral, fruity, and chypre compositions. In this way, they enhance the overall scent experience and bring a touch of authenticity.

Historically, green notes became more prominent in perfumery in response to the need for renewal and hope following the Second World War. Fashion designer Pierre Balmain's release of Vent Vert in 1947 marked a pivotal moment in the industry. This fragrance, a floral green composition featuring prominent essences of galbanum and basil, represented a departure from the norm and paved the way for future compositions involving green and chypre accords.

Although green notes briefly fell out of favour amid the rise of gourmand fragrances, they resurfaced in full force around 2010. As environmental concerns and a desire to return to basics gained traction, perfumers began incorporating softer, more nuanced green notes that also encompass fruity and floral elements. This adaptation allowed green fragrances to align with evolving consumer preferences while maintaining their distinctive character.

In perfumery, green notes are grouped into several categories, with each serving a unique purpose. The freshly cut grass fragrance mimics the aroma of a newly mown lawn and is both uplifting and captivating. Vegetal green fragrances derive their distinctive scent from nitrogen-bearing compounds called pyrazines, naturally occurring substances known for their potent aromas. Combining green characteristics with floral facets, floral green fragrances bring together the brightness of green notes with the vitality and freshness of flowers. Natural green notes, obtained from plants like galbanum and blackcurrant bud, require meticulous extraction methods to capture their earthy and green essence. Petitgrain essential oil, derived from the leaves of the lemon tree, offers a refreshing and nuanced green fragrance.

Overall, green notes bring a touch of freshness, naturalness, and vibrancy to perfumes. Their ability to evoke the essence of nature makes them a valuable tool for perfumers, allowing them to create scents that resonate with consumers seeking these specific olfactory experiences. Whether enhancing a floral bouquet or infusing a fruity composition, green notes add an element of authenticity and elevate the fragrance to new heights.
