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.

Foliar application of urea improved the nitrogen composition of Chenin grapes

The nitrogen composition of the grapes directly affects the developments of alcoholic fermentation and influences the final aromatic composition of the wines. The aim of this study was to determine the effect and efficiency of foliar applications of urea on the nitrogen composition of grapes. This study was carried out during 2023 vintage and in the Chenin vineyard located in Estacion Experimental Mendoza (Argentina). Three urea concentrations 3, 6 and 9 Kg N/ha (C1, C2, and C3, respectively) and control (T) were applied in this vineyard at veraison. In all solutions were added 1ml/l of Tween 80 ® surfactant.

Can soil nitrate explain polyphenol and anthocyanin content in vineyard with similar available soil water regime? 

Nitrogen (N) is quite important nutrient in grapevine development and must quality, but under Mediterranean climatic conditions, available soil water (ASW) during grapevine development can also influence vigour and must quality. The aim was to determine the influence of soil nitrate (NO3-) availability on N foliar, yield, and must quality in vineyards with similar available water holding capacity (AWC). For this purpose, four cv. Tempranillo (Vitis vinifera L.) vineyards were selected. All of them are placed in Uruñuela municipality (La Rioja, Spain), separated less than 2.5 km and in a slope <1 %, in soils with similar soil chemistry properties and with similar rooting depth (ranging between 105 cm and 110 cm).

Overall conceptual characterization of aged dry white wines using a mental descriptive questionnaire

The purpose of the present study was to understand the overall concept of an aged dry white wine using a descriptive mental questionnaire. A total of 680 worldwide participants, grouped according to their involvement in the wine business, replied to an online questionnaire to characterize the sensory analytical and synthetic descriptors of an aged dry white wine. The descriptors were selected using a Check-All-That-Apply (CATA) approach concerning wine colour, aroma, taste, mouthfeel, and global appreciation.

Lipids at the crossroads of protection: lipid signalling in grapevine defence mechanisms

Understanding grapevine molecular processes and the underlying defence responses is vital for developing sustainable disease control strategies. Lipid signalling pathways, involving the synthesis and degradation of lipid molecules, have emerged as a key regulator in plant defence against pathogens. This study aims to elucidate the role of fatty acids and lipid signalling in grapevine’s defence response to P. viticola infection. The expression of lipid metabolism-related as well as lipid signalling genes was analysed, by qPCR, in three grapevine genotypes: Chardonnay (susceptible), Regent (tolerant) with Rpv3-1 resistance loci, and Sauvignac (resistant) harbouring a pyramid of Rpv12 and Rpv3-1 resistance loci.

Exploring the genetic diversity of leaf flavonoids content in a set of Iberian grapevine cultivars: preliminary results

The use of grapevine genetic diversity is a way to mitigate the negative impacts of climate change on viticulture systems. Leaf epidermal flavonoids (including flavonols and anthocyanins) are involved in plant defense mechanisms against environmental stresses, like high temperatures or excessive solar radiation [1,2]. Among other factors, they modulate light absorption, which reduces photoinhibition processes in photosynthetic tissues [1]. Therefore, the identification of grapevine cultivars with an increased content on leaf epidermal flavonoids arises as a potential avenue to improve grapevine tolerance to some detrimental environmental stresses.
