Fir, derived from the needles and branches of coniferous trees in the Abies genus, is a fresh and invigorating note in perfumery. Known for its crisp, resinous, and pine-like aroma, fir is often used to evoke the feeling of a forest or outdoor freshness. It is commonly featured in woody, aromatic, and fresh compositions, adding a vibrant, clean, and natural character to fragrances.

Fir has a fresh, green, and slightly resinous aroma with sharp, piney nuances. Its scent is clean and uplifting, with subtle woody and balsamic undertones that evoke the natural scent of evergreen trees. A faint citrusy or menthol-like freshness adds to its invigorating quality, making fir a refreshing and grounding note that enhances the natural, outdoorsy elements of perfumes.
