Myrcene is a natural compound known as a terpene. Terpenes are aromatic molecules, essentially hydrocarbons, responsible for the distinctive scents and flavors found across the plant kingdom. Myrcene is one of the most common terpenes, widely distributed in plants and contributing to their aromatic profiles. This compound is a monoterpene, found widely in essential oils.
The Distinct Aroma of Myrcene
Myrcene possesses a complex aroma, often described using various sensory descriptors. Its scent is frequently characterized as earthy and musky, sometimes carrying a pungent quality. Beyond these foundational notes, myrcene can also present fruity undertones, particularly reminiscent of ripe mangoes and other tropical fruits, adding a subtly sweet layer to its profile.
The aromatic complexity extends to herbal and spicy nuances. It can evoke the scent of cloves, black pepper, or other warm spices, alongside green and herbaceous notes. Myrcene also contributes a balsamic or resinous quality, often associated with the fresh aroma of hops.
The intensity and specific character of myrcene’s aroma can vary depending on its concentration and purity within a plant. When it is the dominant terpene, its earthy and musky qualities become more pronounced. This blend of earthy, fruity, herbal, and spicy notes creates a unique olfactory experience.
Myrcene’s Presence and Aromatic Contribution
Myrcene is commonly found in numerous plants, where it plays a significant role in their aromatic contributions. Hops, a primary ingredient in beer, contain myrcene as one of their most abundant oils, often comprising a significant percentage of total hop oils. This contributes to the characteristic “green hop aroma” in many beers, although its volatile nature means much of it is lost during the boiling process.
Mangoes are another well-known source, with myrcene contributing to their characteristic fruity and tropical essence. The concentration of myrcene in mangoes can even increase as the fruit ripens, influencing its aromatic development. This terpene is also present in herbs such as thyme, bay leaves, and basil, lending them parts of their familiar scents.
Lemongrass contains notable amounts of myrcene, contributing to its refreshing and sometimes citrusy aroma. In cannabis, myrcene is often the most abundant terpene, making up a significant percentage of the essential oil in various strains. It largely defines the earthy, musky, and sometimes spicy scent commonly associated with many cannabis varieties. Myrcene often acts as a foundational note in these plants, influencing how other scents are perceived.
