“…As White (2003) suggests, the true influence of terroir can only be satisfactorily studied for small areas mapped at large scale, an idea that is strongly supported by the results presented here. Furthermore, such studies, supported by the use of Precision Viticulture, may promote development of a more robust digital terroir function than the regionally derived site index of Tesic et al (2002); the recent work of Taylor (2004) strongly supports this view. Thus, whilst precision viticulture raises questions about the utility of the concept of terroir at regional scales, it has much to offer in promoting robust understanding of the impacts of soil and land attributes on grape and wine production, and thus, how management practices might be modified to gain greater control over fruit and wine quality, and indeed, over at least some of the aspects of terroir.…”

Aims:The aims of this work were to see whether the traditional regionallybased view of terroir is supported by our new ability to use the tools of Precision Viticulture to acquire detailed measures of vineyard productivity, soil attributes and topography at high spatial resolution. Methods and Results:A range of sources of spatial data (yield mapping, remote sensing, digital elevation models), along with data derived from hand sampling of vines were used to investigate within-vineyard variability in vineyards in the Sunraysia and Padthaway regions of Australia. Zones of characteristic performance were identified within these vineyards. Sensory analysis of fruit and wines derived from these zones confirm that contrasting wines may derive from different areas within the same, uniformly-managed vineyard. Conclusions:The performance of vineyards is variable whether yield, fruit quality, wine quality, wine style or value is the measure of interest. The tools of Precision Viticulture enable both growers, winemakers and researchers to see that within vineyards deemed characteristic of a region, terroir is spatially variable at the within-vineyard scale.Significance and impact of the study: Whilst precision viticulture raises questions about the utility of the concept of terroir at regional scales, it has much to offer in promoting robust understanding of the impacts of soil and land attributes on grape and wine production, and thus, how management practices might be modified to gain greater control over fruit and wine quality. Accordingly, at least some of the elements of terroir can be considered to be manageable.Keywords: vineyard variability, grape yield, wine quality, spatial scale, Australia Objectifs : Les objectifs de ce travail sont de montrer si la façon traditionnelle d'appréhender le terroir à l'échelle régionale est confirmée par notre nouvelle capacité à utiliser les outils de la viticulture de précision afin d'obtenir des mesures détaillées sur la productivité du vignoble, les variables du sol et la topograhie à haute résolution spatiale. Conclusions : La performance des vignobles est variable en ce qui concerne le rendement, la qualité du fruit et du vin, le style du vin ou sa valeur. Les outils de la viticulture de précision permettent aux producteurs, aux vinificateurs and aux chercheurs de voir qu'à l'intérieur même des vignobles considérés comme caractéristiques d'une région, le terroir est variable spatialement à l'échelle intra-parcellaire. Signification and impact de l'étude : Alors que la viticulture de précision soulève des questions sur l'utilité du concept du terroir à l'échelle régionale, elle a beaucoup à offrir en favorisant une forte compréhension des effets du sol et des caractéristiques du terrain sur la production de raisins et de vins, et de ce fait, comment les pratiques du management pourraient être modifiées, afin de mieux contrôler la qualité du fruit et du vin. En conséquence, au moins certains éléments du terroir peuvent être considérés comme modulable par la gestion technique du...

“…As a general trend, the highest phenolic concentrations (anthocyanins, in particular) in berries are found in soils with higher clay and/or organic matter content (Choné et al 2001;Tesic et al 2001;Morlat and Bodin 2006;Ramos et al 2015). In addition, a clay-induced soil effect is often greater in wet and intermediate years than in dry years when abundant ABA biosynthesis controls plant responses to drought, independently from soil properties.…”

Grapevine adaptations to water-stress are described, by focusing on soil/root interactions and root-to-shoot signaling to control both plant water relations and fruit ripening process.Root response to drought, tolerance of available rootstock germoplasm, mechanisms of embolism formation and repair in root, aquaporin control of plant water relations, and abscisic acid biosynthesis and delivery are highlighted, by reviewing recent insights coming from either (eco)physiological literature or viticultural assays addressing vineyard-soil relationships.

“…The clay-calcareous and clay soils that had good water-holding and drainage capacity produced wines richer in volatiles than wines produced from fruit grown on sandy soils. Based on a New Zealand study, the authors suggest that physical characteristics of different soil types should be considered relevant at least because of their apparent effect on soil temperature and soil moisture content, which in turn impact vine growth and resulting wine quality (Tesic et al 2002). A greater degree of flexibility in the required soil attributes and the resulting influence on vine water status exists for sparkling wine production than for table wine varieties such as the Bordeaux varieties examined in the work of van Leeuwen et al (2004), due to the lower sugar concentration required at harvest.…”

Abstract:The current understanding of the influences of climate and viticultural practices on fruit quality at harvest and on sparkling wine quality is reviewed. Factors such as variety, clone, planting density, pruning method, local climate and soils, and current and future climate warming are discussed in the context of achieving a desired harvest quality. A common observation was the relatively less intensive viticultural management applied to grapes destined for sparkling wines compared to table wines throughout the world. Few studies have focused on management of fruit specifically for sparkling wine production. Given that it is accepted that a lower pH, higher titratable acidity, and lower soluble sugars than table wine are considered desirable for sparkling wine production, the literature from viticultural studies for table wines which influence these desired fruit quality parameters has been reported. Specific findings on canopy management, leaf removal, and yield manipulation for the production of table wines indicate potential for application and development to optimize fruit for the production of sparkling wines. Fruit quality targets are remarkably uniform across international growing regions but distinct combinations of variety, clone, and management are currently used to arrive at those targets. Further, studies of viticultural management, particularly those that alter cluster temperature and exposure to incident light, yield manipulation, and fruit quality are likely to best inform production techniques that result in fruit quality ideal for the production of premium sparkling wines. New challenges include the need for increasing mechanization to maintain cost-effective production and climate warming, which affects the production of fruit for premium sparkling production in terms of flavor development and high acidity. Current trends include the diversification of growing regions to cooler regions that enable the production of high acid fruit and increased exploration of alternative varieties and clones that are better suited to a warmer climate.
