Nuclear magnetic resonance (NMR) spectroscopy has been
incorporated by the intergovernmental and International
Organization of Vine and Wine (OIV) in its compendium of
International Methods of Analysis of Wines and Musts, for the
quantification of six key parameters in wine – glucose, malic acid,
acetic acid, fumaric acid, shikimic acid and sorbic acid.

Traditionally, several analytical techniques with individual
calibrations are needed to measure these parameters. Now, 1H-NMR
can very accurately quantify a significantly higher number of
compounds in wines – simultaneously, label-free and with a single
calibration.
The advent of advanced techniques like 1H-NMR helps to complete
the chain of authenticity in high-end wine supply chains. The
1H-NMR fingerprint contains hundreds of signals that, when combined
with sophisticated statistics, allows the creation of robust
databases, providing a reference for the contents, varietals, and
regions of production of wines.
Bruker’s NMR Wine-Profiling™ 4.0 module is based on the 400 MHz
NMR FoodScreener™ platform. Now, 1H-NMR profiling has been accepted
by the OIV, and offers the direct, label-free quantification of 53
compounds in a single, automated measurement. This enables the
verification of geographical origin, grape variety of monovarietal
wines, and quality grade, e.g., of Spanish red wines. This
addresses the increasing demand for assurance of the origin and
integrity of wine from the vineyard to the point of sale, enhancing
supply chain surveillance and protecting valuable brands.
Elena Meléndez Álvarez, Director at the Estación Enológica de
Haro, La Rioja, Spain, commented: “The versatility of this
equipment makes it possible to adapt the analyses to our client´s
specific needs. A single analysis is enough to obtain information
about over 50 wine metabolites. Until now, a wine laboratory would
have had to use a combination of various methods to arrive at
similar results. The NMR Wine-Profiling™ 4.0 module gives an
overall view of the wine's main components, such as acidity and
alcohol content and of minor ones, like polyphenols and amino
acids.”
Dr. Iris Mangelschots, President of Bruker BioSpin’s Applied,
Industrial and Clinical Division, commented: “The announcement of
1H-NMR as an official OIV method is an important step forward for
the wine industry, and Bruker is proud to contribute high-value
solutions that lead the way. Robust, quantitative wine-profiling by
1H-NMR is an easy-to-use, rapid and reliable test that provides
growers and producers with the assurance of an authentication
method to detect adulteration or fraud.”
Following this major milestone in NMR-based wine profiling,
Bruker continues to innovate in NMR and is developing advanced food
analysis solutions based on the principles of blockchain to
identify adulteration in high value products such as honey, juice,
spices and olive oil.
