The use of plasma activated water in barrel disinfection: impact on oak wood composition

Abstract

The use of barrels is a practice that improves the quality of wines. The porous structure of wood favors the accumulation of microorganisms that can deteriorate the quality of wines so that barrel cleaning and sanitizing treatments are essential. The burning of sulphur discs has been the most common practice in winemaking because ots biocide effect. Nevertheless, its effectiveness is still insufficient and it is harmful for human health.

In this work, the effect of the use of plasma activated water (PAW) on the volatile composition of medium toasted American oak wood was evaluated. PAW was directly for 30 minutes and fragments of oak staves, measuring 5 cm, were placed in the PAW for 24 hours. Untreated water and sulphiting of the staves by burning sulphur tablets for 15 min were used as control treatments.

The results showed that the use of PAW did not negatively influence the volatile composition of the oak wood. This treatment reduced the content of negative aroma compounds with respect to sulphited being similar to that obtained with untreated water. Furanic aldehydes increased with the use of PAW, while the rest of the analyzed compounds (lactones, volatile phenols, aldehydes and ketones, etc.) were similar to the control with untreated water. Furfural and cis-whiskylactone allowed the discrimination of the samples.

The surprising role of VvLYK6 in grapevine immune responses triggered by chitin oligomers

For sustainable viticulture, the substitution of chemical inputs with biocontrol products has become one of the most considered strategies. This strategy is based on elicitor-triggered immunity that requires a deep understanding of the molecular mechanisms involved in plant defense activation. Plant immune responses are triggered through the perception of conserved microbe-associated molecular patterns (MAMPs) which are recognized by pattern recognition receptors (PRRs) at the plasma membrane.

New oenological criteria for selecting strains of Lachancea thermotolerans for wine technology

The study conducted various fermentations of different grape juices using various strains of Lachancea thermotolerans and one strain of Saccharomyces cerevisiae. Because of the new conditions caused by climate change, wine acidity must be influenced as well as the volatile profile. Non-Saccharomyces yeasts such as L. thermotolerans are real options to mitigate the impact of climate change in wine production.

How are canned wine drinkers perceived? An investigation involving Swiss nationals and different scenarios of outdoor leisure activities

This study examines how people who consume wine in cans are perceived in terms of their basic personality characteristics, helps understand the role of cultural background on people’s perception, and verify the role played by the consumption context on the perception. Our hypothesis is that prejudice and negative attitudes towards wine in cans might exert a negative effect on the evaluation of people who consume canned wine. To evaluate this hypothesis, the consumption of wine in cans was evoked in four different contexts of use during outdoor leisure activity (beach resort, ski resort, desert safari, and party). In order to examine the effect of culture on subject’s response we use participants from Switzerland, a country where three different cultures, associated with three different languages, cohabit.

Application of DEXI PM Vigne sustainability tool to the assessment of alternative vineyard protection strategies

Implementing alternative grapevine systems that incorporate sustainable strategies and innovative farming practices is essential. However, we lack tools for measuring the impact of these new practices on the overall sustainability of vineyards. DEXi PM Vigne (Gary et al., 2015) is a tool developed for ex ante assessment of the sustainability of grapevine cropping systems, from the plot to the farm scale. In the present study, we focused on implementing new strategies of integrated crop protection management with limited pesticide use in vineyards.

Agronomic and oenological behavior of the minority Mandón variety on two rootstocks in the D.O. Arribes

A large population of vines of the Mandón minority red variety (synonymous with Garró) has been located in old vineyards of the D.O. Arribes (Zamora and Salamanca) to conserve and recover this minority variety. The wines made with this variety are characterized by their good structure and color, interesting harmony, an excellently low pH, with high acidity, as well as complex aromas of blue fruits and a marked and expressive minerality.
