Acceptability of canned wines: effect of the level of involvement of consumers and type of wine

Abstract

In recent years there has been a growing demand for alternative packaging designs in the food industry focused on diminishing the carbon footprint. Despite the environmental advantages of cans versus bottles, the traditional environment of wine has hindered the establishment of less contaminant containers. In this context, the objective of this study was to understand and generate knowledge about consumers´ perception of canned wines in comparison to bottled wines.

A total of 127 wine consumers from La Rioja and surroundings participated (traditional wine region). Each consumer evaluated the quality and liking of two young wines (white and red). Each wine was presented in duplicate, but with two different information: “wine in bottle” and “wine in can”. In addition, consumers described the samples using the RATA method. Finally, the involvement of the participants in wine was evaluated through 23 items in a Likert scale. [1]

Four groups of consumers with low (n=16), low-intermediate (n=35), intermediate-high (n=50) and high (n=26) levels of involvement were identified. A two-way ANOVA was calculated for each type of wine (white or red) with level of involvement of the judges and packaging as fixed factors. Consumers with the highest level of involvement perceived canned white wines as lower in quality, and they were less preferred, as they perceived them as more alcoholic and bitter than bottled wines. For red wines, the canned sample was perceived lower in quality, and less preferred than bottled wine regardless of the level of consumer involvement as the wine was perceived with higher notes of reduction (rotten eggs, rubbish) and undergrowth (mouldy).

In overall results show that average traditional wine consumer (except for highly involved) would accept white wines in cans, while they show lower tolerance to canned red wines in comparison to bottled wine.

Energy partitioning and functionality of photosystem II in water-stressed grapevines during heatwaves revealed by continuous measurements of chlorophyll fluorescence

The increased intensity and frequency of heatwaves, coupled with prolonged periods of drought, are a significant threat to viticulture worldwide. During these conditions the more exposed leaves can show visible symptoms of heat damage. We monitored the functionality of photosystem II (PSII) in the field to better understand the impact of heatwaves on canopy performance. A factorial experiment was established in summer 2023 using Shiraz grapevines in the Barossa valley of South Australia, involving water-stressed and well-watered vines.

Characterization of spoilage yeasts from Malbec grapes from San Rafael wine region (Argentina)

The yeast ecosystem in grape musts is quite broad and depends on the region and the health of the grapes. Within this, there are yeasts that can generate fermentative deviations and/or cause defects in the wine. It is very important to address this issue because there are significant economic losses in the wine industry when the fermentation process and/or the organoleptic characteristics of the wine are negatively affected, even more today since climate change has a marked effect on the composition of this ecosystem. The aim of this work is to characterize the behavior regarding detrimental oenological features of potential spoilage yeasts isolated from viticultural environments.

Genetic identification of 200-year-old Serbian grapevine herbarium

Botanist Andreas Raphael Wolny collected a grapevine herbarium from 1812-1824 in Sremski Karlovci (wine region of Vojvodina, Serbia), which represents local cultivated grapevine diversity before the introduction of grape phylloxera in the region. The herbarium comprises over 100 samples organized into two subcollections based on berry colour (red and white varieties), totaling 47 different grape varieties. The objective of this study was to investigate the historical varietal assortment of Balkan and Pannonian winegrowing areas with long viticulture traditions.

Effects of progeny in the modulation of the response to water stress in isohydric and anisohydric varieties

Each grapevine variety has a specific water use regulation response under drought, and it is still unclear whether this regulation results from innate genotypic behavior (iso- and anisohydric), or is a response to environmental factors, namely recurrent water stress priming effects. In the present work, we explored the influence of the field-grown genotypes’ drought memory in the drought-response phenotype of their vegetative progenies, in Trincadeira (isohydric) and Castelão (anisohydric) varieties under a drought event followed by recovery in a glasshouse. Cuttings from both cultivars subjected to full irrigation (FI) and non-irrigation (NI) treatments for 5 consecutive years were used.

Application of antagonistic Metschnikowia strains against Botrytis cinerea in vineyards 

Less and less chemical plant protection products are approved by the E U. Plant pathogenic fungi become increasingly resistant to the active ingredients that have been around for a long time. Besides, there is a valid demand for effective products that can be applied in organic cultivation.
We examined Metschnikowia strains under laboratory conditions in order to find effective strains against B. cinerea. The antimicrobial mechanism of these yeasts is based on the competition for the ferric ions from the environment. Metschnikowia cells release the pulcherriminic acid which chelates with Fe3+, forming the pigment pulcherrimin.
