Automated Chemical Profiling of Wine by Solution NMR Spectroscopy: A Demonstration for Outreach and Education

TL;DR

This paper describes an educational module using NMR spectroscopy to analyze wine, engaging the public and students in chemistry and research through hands-on demonstrations.

Contribution

A novel educational module using NMR spectroscopy for wine analysis to promote science outreach and learning.

Findings

The module successfully engaged 127 visitors, including K–12 students, in NMR-based wine analysis.

Participants learned about NMR operation, wine metabolites, and how chemical composition affects wine characteristics.

Exit surveys showed increased public interest in research and improved understanding of NMR applications.

Abstract

Profiling complex chemical mixtures provides a unique
opportunity
for outreach and education. Here, we develop a teaching module using
one-dimensional 1H nuclear magnetic resonance (NMR) spectroscopy
to study wine. The demonstration is delivered at the Georgia Tech
NMR Center during the Atlanta Science Festival to 127 visitors from
diverse backgrounds, including families with K–12 children.
Participants interact with wine samples through cognitive and sensory
experiences. Visitors engage with a live demonstration of a high-field
NMR spectrometer, including real-time measurement and automated analysis
of 1H NMR spectra for 14 wines. The module enables instructors
to showcase how an NMR spectrometer works, quantify 70 wine metabolites,
and discuss how chemical composition relates to wine characteristics.
Practical examples highlight how 1H NMR can detect wine
fraud. An exit survey suggests that the module increases public interest
and excitement for research. Adults report learning factors affecting
wine characteristics and the basics for how NMR is applied to research.
K–12 students retain information about wine composition and
enjoy sensory aspects of the activity. A description of the demonstration’s
design and implementation is provided to facilitate its adoption in
outreach efforts and introductory chemistry courses.
