Champagne wines are complex hydroalcoholic mixtures supersaturated with dissolved carbon dioxide (CO2). During tasting, while serving the champagne in a glass and for the few minutes that follow, the headspace of the glass is progressively invaded by

In wine tasting, tasters commonly swirl their glasses before inhaling the headspace above the wine. However, the consequences of wine swirling on the chemical gaseous headspace inhaled by tasters are barely known. In champagne or sparkling wine tasti

Spectroscopic techniques based on Distributed FeedBack (DFB) Quantum Cascade Lasers (QCL) provide good results for gas detection in the mid-infrared region in terms of sensibility and selectivity. The main limitation is the QCL relatively low tuning

The favorable downscaling behavior of photoacoustic spectroscopy has provoked in recent years a growing interest in the miniaturization of photoacoustic sensors. The individual components of the sensor, namely widely tunable quantum cascade lasers, l

The chemical space perceived by a consumer of champagne or other sparkling wines is progressively modified all along tasting. Real-time monitoring of gas-phase CO2 concentration was performed, through a CO2-diode laser sensor, along a two-dimensional

We demonstrate a mid-infrared spectrometer based on a quantum cascade laser operated in the intrapulse mode coupled with a custom dense pattern multipass cell. Detection in the range of hundreds of ppm to a few percent has been achieved due to a spec

Key upgrades to a previously developed CO2-Diode Laser Sensor (CO2-DLS) were done to monitor as accurately as possible the level of gas-phase CO2 in champagne glasses. The upgraded CO2-DLS allows to access a wide range of CO2 concentrations (10-100%)
