CDR WineLab® the reliable, complete and fast system of wine analyses

Acetaldehyde (Ethanal) analysis in wine and must

Acetaldehyde is a by-product of yeast metabolism that is formed during alcoholic fermentation. Its formation depends on the fermentation conditions, including a too low fermentation rate.
Acetaldehyde causes an organoleptic defect and it binds the SO2 causing a decrease in molecular SO2.  Molecular SO2 is the form with antioxidant and antiseptic action in wine and must.
