The importance of landscape in wine quality perception: l’importanza del paesaggio nella percezione qualitativa del vino

Abstract

The wine quality is a characteristic that is both difficult to define and communicate, because the quality attributes can be divided into intrinsic (objective, such as alcohol degree, acidity, colour, grape variety etc.) and hedonistic components (extrinsic) that is based upon a subjective evaluation. That means that the attributes that signal quality to consumers are not always objective, but also extrinsic, which impact on wine preference and is a study in progress. The wine area production seems to be a very important variable influencing consumers’ judgement, because it reflects the wine origin, its quality, its traceability (as variety, climate, soil morphology, wine law assessment). The landscape is an important component of the wine origin and it summarises several wine attributes: e.g. climate and soil for grape quality, the local history and the grape production traditions. The mountain viticulture landscape is also an expression of handwork and authenticity. With the aim to quantify the importance of landscape and frame of mind in wine quality perception and how much they can influence consumers’ decision to purchase wine, using a new statistical test, Choice-Based Conjoint AnalysisCBCA, we have evaluate the relevance of the attribute landscape at four different levels. The results pointed out a direct relation that tie a well conserved and scenographic landscape with the wine quality perception and confirm that landscape is an important factor of the extrinsic wine quality.

Qualitative and productive characterization of a minority variety: ‘Branco lexítimo’ in DO Ribeira Sacra (Spain)

The actual climate changes, together with the strong regulation of the European Union and Spanish government, in search of sustainable viticulture, have forced the recovery of minority varieties, expanding the range of grape varieties, as well as the possible development of wines with unique profiles. In the Ribeira Sacra DO (Spain), a comparative study of the agronomic and qualitative behavior of the ‘Branco lexítimo’ variety has been carried out, compared to the majority white variety in the DO: ‘Godello’, located in the same study plot, with identic soil and climatic conditions. The study contemplated the analysis of phenology and leaf water potential, as well as the productive results and the analysis of the must quality, during four seasons: 2018 – 2021.

Impact of red blotch disease on Cabernet Sauvignon and Merlot grape and wine composition and wine sensory attributes

Grapevine Red Blotch disease (RB) is a recently discovered disease that has become a major concern for the viticulture and winemaking industry in California, USA. The causal
agent, Grapevine Red Blotch Virus (GRBV) was identified in 2011 and its presence was confirmed in several states in the US, in Canada, and in Switzerland. It has been demonstrated that RB compromised the regulation of ripening by suppressing specific ripening events, altering the expression patterns of transcription factors and causing hormonal imbalances in Zinfandel.

Survey of pesticide residues in vineyard soils from the Denomination of Origin Ribeiro

Vineyards from mild temperature, high humidity locations receive often treatments with fungicides to prevent damages produced by fungi responsible for mildium, oidium and botrytis infections. In addition, insecticides are also applied to vineyards to fight again pests, which affect directly, or indirectly (as vectors of different diseases), their productivity. A fraction of the above compounds reaches the soil of vineyards, either during application, or when released from the canopy of vines due to rain-wash-off. Thereafter, depending on soil conditions (pH, organic matter) and environmental variables (regimen of rain, slope of vineyards), they might persist in this compartment, be degraded and/or transferred to water masses, modifying the biodiversity of soils and/or affecting the quality of water reservoirs.

Exploring relationships among grapevine chemical and physiological parameters and mycobiome composition under drought stress

Improving our knowledge on biotic and abiotic factors that influence the composition of the grapevine mycobiome is of great agricultural significance, due to potential effects on plant health, productivity, and wine characteristics. Among the various environmental factors affecting the morphological, physiological, biochemical and molecular attributes of grapevine, drought stress is one of the most severe, becoming increasingly an issue worldwide.

Riesling as a model to irrigate white wine grape varieties in arid climates

Regulated deficit irrigation (RDI) is a common viticultural practice for wine grape production. In addition to the potential improvement of water use efficiency, the adoption of this technique favors smaller canopies with higher levels of fruit sun exposure, enhancing quality attributes associated with red wine grapes such as smaller berries with higher tannins and anthocyanins. However, these quality attributes do not necessarily transfer to white wine grapes. The goal of this project was to assess whether partial rootzone drying (PRD) is more suited than RDI to grow high-end white wine grapes in arid climates, especially aromatic varieties, using Riesling as a model.
