Monitoring gas-phase CO2 in the headspace of champagne glasses through diode laser spectrometry

Abstract

During Champagne or sparkling wine tasting, gas-phase CO2 and volatile organic compounds invade the headspace above glasses [1], thus progressively modifying the chemical space perceived by the consumer. Gas-phase CO2 in excess can even cause a very unpleasant tingling sensation perturbing both ortho- and retronasal olfactory perception [2]. Monitoring as accurately as possible the level of gas-phase CO2 above glasses is therefore a challenge of importance aimed at better understanding the close relationship between the release of CO2 and a collection of various tasting parameters.

Based on the tunable diode laser absorption spectroscopy (TDLAS), a diode laser spectrometer (namely, the CO2-DLS) dedicated to monitor gas-phase CO2 in the headspace of champagne glasses was developed [3,4]. The concentration of gas-phase CO2 found in the headspace of champagne glasses served under multivariate conditions was accurately monitored, all along the first 10 minutes following the action of pouring. Our results show the strong impact of various tasting conditions (such as the volume of wine dispensed, the glass shape, the wine temperature, or the level of effervescence, for example) on the release of gas-phase CO2 above the champagne surface. Moreover, a recent upgrading of the CO2-DLS allowed us to evidence that the concentration of gas-phase CO2 in the headspace of a champagne glass is far from being homogeneous in either space or time, with much higher gas-phase CO2 concentrations close to the wine interface.

Biological control of the vineyard: new microbiological findings from CREA-VE

According to the Food and Agriculture Organisation (FAO), 75.866 km2 of the world is dedicated to grape cultivation. About 71.0% of the world’s grape production is destined for winemaking, 27.0% for consumption as fresh fruit and 2.0% as raisin. Grape production is mainly hindered by fungal infections, that can develop both in field and post-harvest.

Study of grape physiology and wine quality (cv. Merlot) in different identified terroirs of the canton Ticino (Switzerland)

Une étude de la physiologie de la vigne (cv. Merlot) et de la qualité des vins a été réalisée au Tessin de 2006 à 2008. La méthodologie utilisée pour cette étude intégrait tous les paramètres qui définissent les terroirs: facteurs naturels (géologie, pédologie et climat), facteurs physiologiques de la vigne et qualité des vins qui sont les révélateurs de la valeur d’un terroir.

Comparative study of qualitative and quantitative characters of grape cultivar ‘Mavrodafni’ (Vitis vinifera L.) grown in different regions of the PDO Mavrodafni Patras

‘Mavrodafni’ (Vitis vinifera L.) is considered one of the oldest grapevine cultivars indigenous to the Greek vineyard, with western Peloponnese being its primary center of cultivation. ‘Renio’ is considered to be either a variant of ‘Mavrodafni’ or an altogether different cultivar. Both ‘Mavrodafni’ and ‘Renio’ can be found in the vineyards of the centers of cultivation, since ‘Renio’ is considered to be more productive compared to ‘Mavrodafni’, and for this reason, it has gradually replaced ‘Mavrodafni’ from cultivation over the course of time. The aim of the present study was to assay the mechanical properties, the polyphenolic content and the antioxidant capacity of skin extracts and must of berries coming from ‘Mavrodafni’ and ‘Renio’, cultivated in the same vineyard as well as in the different regions of cultivation of the PDO Mavrodafni Patras.

Different oxygen and sulphur dioxide concentrations in ‘Sauvignon blanc’ must: effect on the composition of the must and wine

The effects of different oxygen and sulphur dioxide additions to South African ‘Sauvignon blanc’ musts were investigated. Oxygen addition without SO2 protection led to lower levels of certain volatile thiols in the wines, with a corresponding decrease in certain phenols and glutathione concentrations.

Isolation, biofilm formation and control of the wine spoilage yeast Brettanomyces bruxellensis

Brettanomyces bruxellensis, commonly referred to as “Brett,” is one of the most notorious microorganisms implicated in wine spoilage. This yeast species has developed a noteworthy resistance to sulfur dioxide, a widely used preservative in winemaking, prompting the wine industry to seek new antimicrobial agents.
