A term (also fermentation flavour) for the aromatic substances produced during fermentation as a result of metabolic processes, especially esters, which are responsible for many fruity notes in wine. Certain aromas are already present in the grapes(primary aroma) and are only developed during the ageing of the wine, often over many years or even decades (tertiary aroma or ageing aroma). The toast flavour that develops during barrique ageing is neither a secondary nor a tertiary flavour in the classic sense. See also flavour, toasting and typicity.

There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
