The “resources profile®”: a relevant decision and support system for adapting viticultural practices to soils agronomic properties and limiting their environmental impacts


Soil is a three-dimensional complex system, which constitutes a major component of Terroir. Soil characteristics strongly influence vine development, grape oenological potentialities and thus wine quality and style.

Soil profile description by means of pits is essential for a relevant characterization of the soil. However, the interpretation of results is very difficult for non-specialists, as for most of advisors or winegrowers, due to the multitude of parameters and their variability within the soil profile.

We propose here a novel method to represent soil parameters variability, integrating thickness and depth of the different horizons, providing an operational Decision and Support System (DSS) for winegrowers and advisors.

For each parameter, soil profile is represented by a vertical block divided in 10 centimeters layers, in order to highlight the thickness of the different horizons. According to the parameter value, a specific color code, based on analytical references, is applied for each horizon. This method has been applied on different soil parameters : coarse fragments content, clay content, slaking and compaction index, carbonate content, pH, organic content and stock, carbon/nitrogen ratio, cation exchange capacity, exchangeable cations contents, base saturation percentage.

This method, called « Resources Profile® », has been tested on a large number of soil types, representative of soils variability in Bordeaux wine production area (France). It allows to easily visualize soil parameters variability within soil profile and to evaluate agronomic properties, such as hydrological soil properties, organic and calcic status, mineral resources or degradation sensitivities.

We believe that the « Resources Profile® » is a relevant DSS for adapting viticultural practices to soils characteristics and for limiting their environmental impacts. This DSS is likely to facilitate the spread of soil science knowledge to the vinegrowing industry.

Politics meets terroir. The story of Prosecco – Are GI’s just a protectionist racket?

The recent Free Trade Agreement negotiations between Australia and the European Union have again put the issue of Geographical Indications (GIs) in the spotlight. Australia has long demonstrated its understanding of GIs and maintains a clear and rigorous GI protection system for wine. For many years, Australia’s wine sector was a strong advocate for GIs and a strong system to protect the

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.

Rare earth elements distribution in grape berries

Rare Earth Elements (REEs) include 15 lanthanides, yttrium and scandium. Their occurrence in soil and plants seems to be closely tied to the geological composition of the underlying mother rock, to the physical and chemical properties of the soil and to the specific ability of the plant to take up and accumulate these microelements.

Methoxypyrazine concentrations in grape-bunch rachis are influenced by rootstock, region, light, and scion.

Methoxypyrazines (MPs) are readily extracted from grape berry and rachis during fermentation and can impart “green” and “herbaceous” sensory attributes to wine. Irrespective of whether MPs, including 3-isobutyl-2-methoxypyrazine (IBMP), 3-isopropyl-2-methoxypyrazine (IPMP), and 3-sec-butyl-2-methoxypyrazine (SBMP), are extracted from berry or other vine material, techniques for remediation of wine with overpowering sensory characters attributable to MPs suffer from poor specificity or produce undesirable sensory outcomes, meaning that alternative control approaches are needed.

The impact of global warming on Ontario’s icewine industry

Ontario’s wine regions lie at the climatic margins of commercial viticulture owing to their cold winters and short cool growing season. The gradual warming of northern latitudes projected under a human-induced climate change scenario could bring mixed benefits to these wine regions.
