Acetaldehyde
Advanced Faults & Defectsपरिभाषा
An oxidation compound giving a bruised-apple or sherry-like aroma.
गहराई से
Formed when alcohol is oxidized. At low levels (below perception threshold), acetaldehyde is a normal wine component. At elevated levels, it signals oxidation — the wine smells of bruised apple, overripe fruit, or until Sherry-like nuttiness. In Sherry production, acetaldehyde is deliberately produced under flor yeast. In table wine, it indicates a fault.
