“…The length of growing season is also a determining factor in grape composition (Jackson and Lombard 1993, Duchene and Schneider 2005, Webb et al 2007). Some authors confirmed that earlier ripening periods in a season may have negative effects on grape composition and, therefore, on wine quality Davis 2000, Hall andJones 2009). Furthermore, grape texture is linked to growing location, reflecting a terroir influence on grape quality (Le Moigne et al 2008a).…”

“…The relationship between climate and berry properties has attracted considerable attention; temperature is recognized as the main climatic variable affecting vintage quality (Jackson andLombard 1993, Hall andJones 2009). Nevertheless, the impact of temperature on harvested grape quality can vary for different grapevine cultivars as a consequence of genotype-environment interaction.…”

Texture analysis is a well-established analytical technique in the food industry for evaluating the mechanical and physical characteristics of both raw ingredients and finished products. Instrumental mechanical properties of table grapes, acquired using universal testing machines equipped with specific probes, may be of interest in the viticulture and postharvest sectors to recognize the potential of each variety and help satisfy market requirements. The measured parameters are related to some sensory properties and, therefore, indirectly to consumer acceptability of the product. As texture analysis is a rapid and low-cost analytical technique, it can also be favorably applied in enology as a routine tool for monitoring winegrape quality. Among the different mechanical parameters measurable, berry skin thickness and hardness are indices that reflect anthocyanin extractability and dehydration kinetics with adequate reliability. This review collects the most recent research results from grape texture studies, emphasizes the potentiality and limits of this analytical technique when applied to grape studies, and highlights trends that require further understanding.

“…Therefore it is possible, for example that climate, disease and pest conditions in the Italian regions may become typical for South Germany in the future. Changes in the location and extent of areas suitable for viticulture are anticipated for the 21st century (White et al 2006, Hall & Jones 2009). Hall & Jones (2009), for example, expect that Australia will experience a decrease of areas suitable for high quality wines, since viticulture is close to reaching its southern limit on this continent, and there is no land to allow it to migrate further south.…”

We estimated changes in viticulture conditions over the 21st century in BadenWürttemberg, southwest Germany, using scenario runs of 3 regional climate models for 1961-1990, 2021-2050 and 2071-2100. The scenario runs were compared and validated with local observational data. By applying the Huglin Index, possible expansions of areas suitable for viticulture, as well as suitable grape varieties for the region, were determined. Optimal grape varieties are changing to those more suitable to a warmer climate. This development was found in all examined simulation runs.

The scenarios used cover the time period up to 2055, and the main method applied was the Huglin Index (HI, Huglin 1978). The HI is a commonly used heat summation index to identify suitable areas for different grape varieties, and has been applied in studies of Tonietto & Carbonneau (2004) as well as Petgen (2007).In the present study, we examined the possible expansion of suitable areas for different grape varieties, using the HI, for 3 different periods, 1961-1990, 2021-2050 and 2071-2100. Simulation runs of 2 dynamical regional climate models (DRCMs) were used, the regional model REMO, developed by the Max-PlanckInstitute for Meteorology (Jacob & Podzun 1997, Jacob et al. 2007, and the Consortium for Small-scale Modeling (COSMO) model in climate limited-area Modelling (CLM) mode (COSMO-CLM or CCLM) (Steppeler et al. 2003. The Special Report on Emissions Scenarios (SRES) A1B and B1 were used for the simulation runs (IPCC 2007). Both emission scenarios are based on the assumption of an integrated world with rapid economic growth. B1 includes reductions in material intensity and the introduction of clean and resourceefficient technologies, together with a change to a more service and information orientated economy. A1B comprises the rapid introduction of new and more efficient technologies together with a balanced use of all energy sources, but is less focused on environmental sustainability than B1. For 2 different climate stations, the model output is validated and compared with simulations of the statistical based regional climate model WETTREG of the Max-Planck-Institute for Meteorology (Enke et al. 2006, Spekat et al. 2007). The present study assesses potential changes and examines the possible expansion of those areas suitable for viticulture over a long time scale (up to 2100) according to the 2 DRCMs. In addition, we discuss possible limits of the models used and of the HI. DATA AND METHODSData from 3 models, 2 dynamical and one statistical, were used to validate the results and were coupled with observation data for verification purposes. To determine values for a particular point, an inverse distance weighted interpolation was applied using the surrounding dynamic...

“…Temperatures in wine regions worldwide have increased 1-3°C over the last 25 to 50 years Hall and Jones, 2009) and approximately 0.1°C/decade in New Zealand (Mullan et al, 2010), which would mean that the 1971-2000 climate normals used in this research should be updated to the next period normals once the data become available. For example, showed that GDD values from stations from the 1971-2000 climate normals in the western US were on average 10 % higher than those experienced during the middle of the 20th century.…”

Aims: This research analyzes four climate indices derived from gridded, interpolated data to assess New Zealand's climate structure and variation among wine regions. Methods and results:High resolution gridded data based on 1971-2000 climate normals was used to characterize climate indices depicting viticultural suitability in a geographic information system. The statistical properties of each index were assessed over 21 New Zealand viticulture regions. The results show predominately cool to moderately warm climate suitability in New Zealand, comparable to many European and United States regions. While many viticulture regions have one primary class of suitability, variability of climate within regions can be significant, with some regions containing two to four climate classes, making them suitable for a greater range of cultivars. Conclusion:While the indices depict broad patterns expected over New Zealand, both within and between region variations can be substantial among the indices. However, two indices, Growing Season Average Temperature (GST) and Growing Degree-Days (GDD), are functionally identical, but GST is easier to calculate and overcomes many methodological issues in GDD.Significance and impact of the study: This research provides the basis for evaluating general suitability for viticulture in New Zealand, assists comparisons between viticulture regions in New Zealand and worldwide, and offers growers measures of assessing appropriate cultivars and sites.
