is the overall ecological awarness among Spanish winemakers related to their attitudes towards natural wines?

Abstract

The Agenda 2030 of the EU sets out the main guidelines for transitioning towards a resilient, green and safe economy. To this regard, the wine sector is experiencing an ecological transition in different ways such as increasing the production of ecological crops, or promoting the production of wines under more environmental-friendly and healthier (i.e., lower levels of SO2) products. These alternatives to conventional production are a smaller proportion of wines, in constant growth and demand, and follow alternative and minority practices, which range from sustainable to deeply philosophical thoughts. Among these methods there are organic, biodynamic and, more recently, natural wines. While organic and biodynamic wines are well defined as they are subject to certifications, the concept of natural wines is blurry and projects important discrepancies and conflicts among the different actors of the wine industry. In this context, this work examines the attitudes among Spanish winemakers towards natural wines and their relationship with their overall Ecological compromise. Therefore, an online questionnaire was completed by 307 Spanish winemakers. It consisted in three main parts: 1) evaluation of their attitudes towards natural wines with 32 effective questions (covering 8 different dimensions related to health, economy, ecology, tradition, mode, social identity, technology, and sensory) using a 4-point-Likert scale, 2) overall ecological awareness in their everyday life through a 13-item questionnaire measuring the frequency of following eco-friendly acts in a 6-point scale (an Eco-Score was calculated as the average of 12 out of the 13 questions), and 3) demographic information.

Results shows four main independent drivers involved in the formation of the different attitudes among Spanish winemakers towards natural wines related to the following dimensions 1) Ecological Awareness, Tradition and Social Identity, 2) Sensory and Technology, 3) Health, and 4) Economy. Interestingly, their attitudes in terms of ecological awareness, tradition and social identity towards natural wines are strongly linked to their overall ecological awareness. Five main clusters of winemakers could be identified, showing Cluster 1 (22% of participants) significantly higher Eco-score than Cluster 4 (12%). Clusters 2 (25%), 3 (21%) and 5 (21%) show an intermediate ecological awareness. The implications of this study are wide in that how experts, that are opinion leaders in the wine sector, conceptualise natural wines can help to understand their behaviour in terms ecological transition.

Biodiversity and biocontrol ability of Trichoderma natural populations in soil vineyards from Castilla y León region (Spain)

Trichoderma is a microorganism present in many agricultural soils and some of its species could be used as natural biological control agents. In this work, the presence of natural populations of Trichoderma was estimated in soil vineyard and its biocontrol capacity against Phaeoacremonium minimum, one of the main agent causals of grapevine trunk diseases instead of using pesticides. Moreover, physicochemical variables in soil such as pH, organic matter and nutrients were evaluated to determine a possible correlation to natural populations of Trichoderma.

A sensometabolomic approach to understand wine mouthfeel percepts

Targeted analytical methods can overlook compounds that are a priori unknown to play a role in the mouthfeel sensations. This limitation can be overcome with the information provided by untargeted metabolomic analysis using UPLC‐QTOF-MS. To this end, an untargeted metabolomic approach applied to 42 red wines has allowed development of a model with predictive capacity by cross-validation for the “dry”, “oily” and “unctuous” sensations perceived by a sensory panel. The optimal PLS model for “dry” retained compounds with positive regression coefficients (≥ 0.17) including a trimer procyanidin, a peptide, and four anthocyanins.

Oenococcus oeni clonal diversity in the carbonic maceration winemaking

This essay was aimed to describe the clonal diversity of Oenococcus oeni in the malolactic fermentation of the carbonic maceration (CM) winemaking. The free and the pressed liquids from CM were sampled and compared to the wine from a standard winemaking with previous destemming and crushing (DC) of grapes [1]. O. oeni strain typification was performed by PFGE as González-Arenzana et al. described (2014) [2]. Results showed that 13 genotypes, referred as to letters, were distinguished from the 49 isolated strains, meaning the genotype “a” the 27%, the “b” the 14%, the “c” the 12%, the “d and e” the 10 % each other, and the remaining ones less than the 8% each one.

Mycorrhizal symbiosis modulates flavonoid and amino acid profiles in grapes of Tempranillo and Cabernet Sauvignon 

Arbuscular mycorrhizal fungi (AMF) symbiosis is probably the most widespread beneficial interaction between plants and microorganisms. AMF has been widely reported to promote grapevine growth, water and nutrient uptake as well as both biotic and abiotic stress tolerance[1]. However, the impact of AMF on grape composition has been less studied. The aim of this work was to evaluate the effects of the association between two commercial grapevine cultivars (Tempranillo and Cabernet Sauvignon grafted onto 110 rootstock) and AMF on the anthocyanin, flavonol and amino acid concentrations and profiles of grapes.

Culturable microbial communities associated with the grapevine soil in vineyards of La Rioja, Spain

The definition of soil health is complex due to the lack of agreement on adequate indicators and to the high variability of global soils. Nevertheless, it has been widely used as synonymous of soil quality for more than one decade, and there is a consensus warning of scientists that soil quality and biodiversity loss are occurring due to the traditional intensive agricultural practices.
In this work we monitored a set of soil parameters, both physicochemical and microbiological, in an experimental vineyard under three different management and land use systems: a) addition of external organic matter (EOM) to tilled soil; b) no tillage and plant cover between grapevine rows, and c) grapevines planted in rows running down the slope and tilled soil.
