The role of the cask in the evolution of spirits

The cask doesn’t just contain the spirit; it actively shapes its taste and character. Several elements influence this evolution:

  • Wood species: Oak is the most commonly used wood, but there are different varieties (French, American, European oak), each with its own specific nuances.
  • Burning: The inside of barrels is often heated to release aromatic compounds. Light toasting brings notes of vanilla and flowers, while intense toasting develops aromas of caramel, cocoa and spices.
  • Barrel age: A new barrel impregnates the eau-de-vie more rapidly with tannins, while a previously used barrel offers a smoother, more gradual extraction.

The impact of aging conditions

Aging is about more than the quality of the barrel: the environment plays a crucial role.

  • Temperature and humidity: A warm climate accelerates the interaction between wood and spirit, while a humid climate reduces alcohol evaporation and favors a rounder texture.
  • Ventilation and atmospheric pressure: Air circulation helps avoid sudden variations in maturation and ensures batch homogeneity.

The art of blending

Aging a spirit doesn’t just mean waiting several years before bottling it. Each barrel evolves differently, and blending becomes a key stage in the process.
