CQC Study of Chemical Origins for Off-Aromas in Wine
Analysis of rejected wines at Sonoma County Harvest Fair Presented by Peter Weber CQC - ASEV Eastern Meeting - June 2003 - Lancaster PA
Summary: Study compared 40 wines rejected by judges for off-aromas to the accepted control sample. Eight compounds commonly associated with cork defects were analyzed. Only TCA showed correlation to sensory rejection. The other seven compounds were either not measurable, or found in equal frequency between the rejected wines and the acceptable controls.
