Tertiary Aromas

Tertiary aromas are aromas that develop in wine during maturation and bottle ageing, after the primary grape aromas and secondary fermentation-related aromas have evolved. They can include leather, tobacco, forest floor, mushroom, dried fruit, nuts, honey, spice and other savoury or mature notes. Tertiary aromas are often associated with wines that have developed over time, but their presence does not automatically indicate quality or age-worthiness.

How tertiary aromas develop

During barrel and bottle ageing, wine undergoes slow chemical changes that alter its aroma and flavour. Oxygen exposure, lees contact, oak maturation, bottle closure, storage conditions and the wine’s original composition all influence the development. Controlled oxidative ageing can create distinctive tertiary aromas in some styles, while excessive unintended oxidation is a fault.

Examples in red and white wines

Mature red wines may develop leather, tobacco, dried herbs, mushroom, forest floor, truffle and dried cherry notes. Mature white wines may show honey, nuts, beeswax, toast, dried citrus and petrol-like notes in Riesling. The profile depends on grape variety, production method and storage.

Primary, secondary and tertiary aromas

• Primary aromas: associated with the grape variety and fruit, such as citrus, berry, floral or herbal notes.
• Secondary aromas: associated with fermentation and winemaking, such as yeast, brioche, butter and oak-derived notes.
• Tertiary aromas: developed through maturation and bottle ageing, such as leather, tobacco, nuts and forest floor.

Example: a mature Burgundy may show dried cherry, mushroom, forest floor and spice alongside its remaining red-fruit character.

Chef’s note: tertiary aromas can add complexity, but musty or damp-cardboard notes may indicate cork taint rather than desirable bottle development.
