Olfactory description

 

This birch tar comes from a production made approximately in the 1980s and has remained aging for over forty years. The prolonged maturation process has softened some of the material's more aggressive facets, revealing an exceptional aromatic complexity.

 

Historically considered one of the fundamental materials in leather perfumery, birch tar presents an intensely smoky, dry, and profoundly characteristic profile. However, prolonged aging provides a remarkable roundness rarely found in recent materials.

 

The opening shows notes of dry smoke, charred wood, and tanned leather. As it evolves, phenolic, balsamic, and resinous nuances appear, accompanied by slight hints of dark tobacco, aged wood, and old leather. The drydown is persistent, warm, and extraordinarily complex.

 

Far from being limited to a simple smoky note, this material displays an aromatic richness that has made birch tar one of the most influential raw materials in the history of perfumery.

Historical interest

 

Birch tar played a fundamental role in the creation of the great leather perfumes of the 20th century. Before the appearance of many modern molecules, it was one of the main materials used to recreate the scent of tanned leather, smoke, and charred wood.

 

Preserved specimens from the 1980s are increasingly scarce and offer an exceptional opportunity to experience a historical raw material after decades of natural evolution.

 

The prolonged aging has softened some of the material's more aggressive facets, allowing appreciation of balsamic, resinous, and woody nuances that are often hidden in recent materials.

 

Collector's item

 

This vintage birch tar is a true collector's item for perfumers and enthusiasts of historical raw materials.

 

Its rarity, age, and extraordinary aromatic complexity help to understand why birch tar was considered for generations one of the fundamental pillars of traditional leather perfumery.

 

More than a simple ingredient, it represents a living part of the history of classical perfumery.
