Tertiary aromas: aromas of maturation
The standard
An aroma origin in maturation assigns a note to time: only when a note comes from ageing or storage and not from grape or fermentation does it count as tertiary.
Criteria
- The note is absent in the young wine and appears only with maturation
- It arises through ageing, storage, oxidation or esterification
- It overlays or replaces fruit and fermentation aromas
- Its appearance requires time, not an addition
Distinction
Tertiary aromas ≠ primary aromas: these come from the grape. Tertiary aromas ≠ secondary aromas: these arise during fermentation. An aroma origin in maturation separates both from the group that comes from time and from bottle ageing.
