Viticulture and climate: from global to local


Aims: This review aims to (1) present the multiple interests of studying and depicting and climate spatial variability for vitivinicultural terroirs study; (2) explain the factors that affect climate spatial variability according to the spatial scale considered and (3) provide guidelines for climate zoning considering challenges linked to each methodology considered.

Methods and Results: Scientific contributions of the 12 Terroir Conferences proceedings since 1996 have been reviewed together with Vitis-Vea, Oeno One, ASEV, ScienceDirect, SpringerLink and Wiley Online Library data bases with various keywords combination of “Climate”, “Spatial analysis”, “Wine”, “Viticulture”, “Area”, “Scale”, “Terroir” and “Zoning”, including English, Italian and Spanish languages. This literature review led to the classification of climate spatial analysis related studies according to the spatial extent, scale, source of data, spatialization method and indices used to depict the spatial structure of climate. To illustrate the scale issue for climate spatial analysis of wine growing terroirs, a comparison of spatial structure of climate depicted by either large scale data (Worldclim v2.0and CRU4.2TS), point data (weather stations) and spatial interpolation of local weather stations was performed in Bordeaux (2001-2005 period) wine region. It shows the limitations of coarse resolution (macroclimate scale) data to depict mesoscale data.


The climate spatial variability of wine producing regions have been widely documented, yet not exhaustively. However, climate indices and period are not standardized which makes it difficult to compare the climate of terroirs based on the existing literature. Analysing spatial structure might lead to different conclusions according to the source of the data, and thus special care should be provided to the methods, scale and uncertainties associated to spatial data.

Significance and Impact of the Study: This study provides in a nutshell an overview of climate analysis for terroir studies that could be useful for students, winegrowers and researchers interested in climate spatial analysis.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
