Analysis of wine

Objective


Scientific support has been given for the application of the nuclear magnetic resonance (NMR) technique to the control of wine sugaring (chaptalization).

The validation of national results (10% of 1200 samples) for the European wine databank has been performed, as well as the measurement of wine databank samples for Portugal, Greece and Luxembourg who are not yet equipped with NMR.

Research on the use of NMR to determine the watering of must and wine as well as the determination of the origin dependent amount of amino acids in wine were slowed down drastically, due to the budgetary difficulties with respect to the installation of a second NMR spectrometer.

NMR site specific natural isotope fractionation (NMR-SNIF) has been applied to the control of wine ethanol to be sold at the Rotterdam spot market.

Lastly, approximately 50 to 80 data per wine sample of the 1991-1992 harvest have been prepared for input into the European databank.

The Environment Institute has participated 2 round robin experiments to evaluate the analytical procedures for the detection of lead in wine and is an observer in an ad hoc group for the detection of watering of wine by mass spectrometry (MS).
