Fragrance Notes Are Layers Of Scent That Are Layered To Form The Final Fragrance. Fragrance Notes Are Categorised Into Three Main Elements Based On How Long They Take To Evaporate, And How Long They Typically Last Following Application: Top Notes, Heart Notes And Base Notes.
Stems Greens
Stems Greens captures the vibrant, crisp, and freshly cut essence of plant stalks. It offers an intensely sharp, watery-green, and slightly bitter aroma, evoking the snap of a broken stem or crushed leaves. It provides a highly natural, vegetal, and uplifting freshness, often used to inject a vivid, dewy realism into green and floral compositions.
Origin & Extraction Of Stems Greens
The concept of "Stems Greens" and similar photorealistic green notes, which capture the sharp, watery essence of broken plant stalks, is a relatively modern innovation in perfumery. For centuries, perfumery focused on volatile citrus oils, florals, and heavy resins. The deliberate use of intensely fresh, realistic green notes only began to gain prominence in the 20th century. This evolution was driven by the desire to capture nature's fleeting freshness, moving beyond the heavier, abstract compositions of the past and aiming for a vivid, dewy realism.
The rise of high-definition green accords, including "Stems Greens," reflects the post-mid-20th century trend toward fresh, natural, and contemporary fragrances. These notes are essential in modern compositions, particularly in the green, fresh fougère, and floral categories, where they are used to inject vitality, crispness, and a slightly bitter, vegetal complexity. Their role is to provide a highly natural, uplifting opening that simulates the scent of a garden or forest after a rain, creating sophisticated transparency in green and floral creations.
Extraction Methods of Stems and Greens
Historically, aromatic compounds from stems and green leafy materials were obtained through traditional manual techniques such as maceration and infusion. Maceration involved soaking coarsely powdered plant parts in a solvent for several days, while infusion used hot or cold water for a shorter duration to extract readily soluble constituents. In some traditions, such as ancient Persian perfumery, simple distillation was used to capture volatile vapors from green materials. For delicate floral-green notes, the enfleurage method—absorbing aromas into cold fats—was also utilized to preserve scents that would be destroyed by heat.
Modern commercial extraction for stems and greens has shifted toward advanced technologies that prioritize purity and sensitivity. Steam distillation remains a standard for producing essential oils, while solvent extraction using hexane or ethanol is common for creating concretes and absolutes. Because leafy materials contain high amounts of chlorophyll, which can interfere with the fragrance profile, contemporary processes often include a pre-treatment step with non-polar solvents like n-hexane to remove wax and fats. Recent innovations include supercritical CO2 extraction, which allows for highly tunable, solvent-free results at low temperatures, and ultrasound-assisted extraction (UAE) to disintegrate cell walls and increase efficiency without significant heat exposure.
The "Stems Greens" note is a contemporary perfumery tool, prized for its ability to convey photorealistic freshness—the sharp, dewy snap of a broken plant stalk or crushed leaves. It is essential in modern green and transparent floral fragrances that aim to simulate a garden or forest after rain. While abstract green accords dominated the 20th century, this specific note is used to inject immediate vitality and complexity into the opening, preventing compositions from feeling heavy or synthetic. It moves beyond simple leafy notes by adding a watery, slightly bitter realism that enhances natural transparency.
- A significant deployment of this vivid green realism can be found in fragrances like Frédéric Malle’s En Passant, where the lilac accord is supported by a palpable sense of wetness and green stem, making the flower feel entirely natural.
- Similarly, notes reflecting this freshly cut, bitter vegetal essence are critical to the structure of modern classics such as Diptyque's L'Ombre dans l'Eau, grounding the rose and blackcurrant leaf with a hyper-realistic, dewy green backdrop.
In the designer realm, the crisp, slightly bitter aroma of Stems Greens is frequently used to modernize floral bouquets and aquatic compositions. It serves as a sophisticated counterpoint to sweeter elements, ensuring the fragrance maintains an airy, fresh quality and a luminous lift throughout its development. This technique is particularly effective in springtime or fresh fougère categories, providing a clean, invigorating sharpness.
For connoisseurs of green scents, the Stems Greens note offers an appreciated degree of naturalism and structure. It is a signature element in niche perfumery seeking to evoke specific outdoor environments, such as captured in the aesthetic of many Jo Malone fragrances or Hermès’ Les Jardins collection, where an authentic, garden-fresh sensation, often including the aroma of crushed foliage and broken stems, is paramount to the overall olfactory narrative. The note provides the structural backbone for compositions demanding clear, high-definition freshness, elevating a simple "green" scent to a rich, atmospheric experience.
Sustainability Of Stems Greens
Sustainability of Stems Greens
- Adoption of green chemistry principles to minimize waste and eliminate the generation of hazardous substances during the production of synthetic green molecules
- Utilization of ultrasound-assisted extraction (UAE) and supercritical CO2 methods to significantly reduce energy consumption and the need for organic solvents
- Implementation of precision engineering to maximize atom economy, ensuring that the highest proportion of starting materials is incorporated into the final fragrance compound
- Development of biodegradable aromatic molecules, such as leaf alcohol, that break down into non-hazardous substances after use to prevent environmental persistence
- Support for educational initiatives like the Green STEMS Project to foster community engagement and empathy toward nature and sustainable environmental practices
Trivia
The iconic scent of freshly cut grass and crushed leaves is created using a molecule called cis-3-hexenol, which is known in the industry as leaf alcohol.
