Multidisciplinary strategies for understanding ill-defined concepts

Aims: The objective of the present work is to review strategies applied to decrypt multidimensional and ill-defined concepts employed by winemakers and to illustrate these strategies with recent applications. Methods and Results: The first group of strategies are based in acceding long-term memory of experts including description and association tasks. For example, in a recent study, Spanish […]

Adaptation to climate change by determining grapevine cultivar differences using temperature-based phenology models

OENO One – Special issue Grapevine phenology is advancing with increased temperatures associated with climate change. This may result in higher fruit sugar concentrations at harvest and/or earlier compressed harvests and changes in the synchrony of sugar with other fruit metabolites. One adaptation strategy that growers may use to maintain typicity of wine style is […]

Understanding provenance and terroir in Australian Pinot noir

Aims: This study aimed to (1) characterise colour and phenolic profiles of commercial Australian Pinot noir wines, (2) understand regional drivers of sensory and volatile profiles of commercial Australian Pinot noir wines, and (3) generate a deeper understanding of where Australian Pinot noir wines profiles sit in an international context. Methods and Results: A broad set of commercial […]

Evaluation of six red grapevine cultivars inoculated with Neofusicoccum parvum in a “terroir” of La Mancha wine región (Spain)

Aim: Among Botryosphaeriaceae species associated with Botryosphaeria dieback of grapevines, Neofusicoccum parvum is one of the most virulent and fastest wood-colonizing fungi. This study aimed to evaluate the susceptibility of six red grapevine cultivars (“Bobal”, “Monastrell”, “Garnacha Tinta”, “Moravia Agria”, “Tinto Velasco” and “Moribel” to N. parvum, under field conditions. Methods and Results: Pathogenicity studies were conducted, over two consecutive years, with one-year […]

Developing and assessing different cordon establishment techniques for long-term vineyard management

Aim: The aim of this research is to quantify the impacts of different cordon establishment techniques on vine health and longevity. It is hypothesised that wrapping developing cordon arms tightly around the cordon wire will cause a constriction of the vascular system, becoming worse over time and disrupting the flow of water and nutrients. Methods and […]

Towards the definition of a terroir of grape dehydration for the production of ‘Passito’ wines in Valpolicella (Italy)

Aim: The aim of this study was to investigate the relationship between the molecular response of grapes during postharvest dehydration and the specific environment of two naturally ventilated rooms (called ‘fruttai’), located in two different sites in Valpolicella.  Methods and Results: Grapes of Corvina and Corvinone were harvested in the same field in 2018 and placed in […]

Selecting varieties best adapted to current and future climate conditions based on ripening traits

Aim: The aim of this study was to quantify key berry sugar accumulation traits and characterize their plasticity in response to climate variation from data collected from different cultivars over seven years from an experimental vineyard. Methods and Results: Berry samples were collected weekly from different Vitis Vinifera (L.) cultivars at four replicate locations within a common-garden randomized complete […]

Application of fluorescence spectroscopy with multivariate analysis for authentication of Shiraz wines from different regions

Aim: To investigate the possibility of utilising simultaneous measurements of absorbance-transmittance and fluorescence excitation-emission matrix (A-TEEM) combined with chemometrics, as a robust method that gives rapid results for classification of wines from different regions of South Australia according to their Geographical Indication (GI), and to gain insight into the effect of terroir on inter regional variation.

Development of the geographic indication vale do São Francisco for tropical wines in Brazil

Aim: Geographical Indications-GI are commonly used to protect territorial products around the world, such as cheese and wine. This qualification is useful because it improves the producer’s organization, protects and valorizes the distinct origin and quality of the product, increases recognition and notoriety, and adds value for products. Tropical wines are mainly produced in Brazil, India, […]
