“…Alternatively, models relating macroclimate to local climate parameters are used to statistically downscale (Hewitson et al ., ) climate model outputs before applying models of the relationship between local climate and viticulture (Santos et al ., ). Statistical models have been applied to measure climate change impacts on yield (Santos et al ., ), grapevine pathogens (Francesca et al ., ; Calonnec et al ., ), and various measures of harvest quality from vintage ratings (Jones et al ., ; Moriondo et al ., ) and harvest prices (Webb et al ., ) to sugar content (Urhausen et al ., ; Neumann & Matzarakis, ) and other physicochemical properties of berries (Barnuud et al ., ). Dynamic, or process‐based, crop growth models have been widely used for measuring climate impacts on annual crops (Rötter & van de Geijn, ; Rosenzweig et al ., ) but have been less often applied to studies on viticulture. Dynamic models of grapevine growth range from growing season, field‐scale simulation models primarily used as decision‐support and forecasting tools, to functional models offering insight into specific plant physiological processes (Moriondo et al ., ). Several of the most widely used crop growth models have been applied to assess impacts of, and adaptation to, future climate projections.…”

The cultivation of grapevines for winemaking, known as viticulture, is widely cited as a climate-sensitive agricultural system that has been used as an indicator of both historic and contemporary climate change. Numerous studies have questioned the viability of major Accepted ArticleThis article is protected by copyright. All rights reserved.viticulture regions under future climate projections. We review the methods used to study the impacts of climate change on viticulture in the light of what is known about the effects of climate and weather on the yields and quality of vineyard harvests. Many potential impacts of climate change on viticulture, particularly those associated with a change in climate variability or seasonal weather patterns, are rarely captured. Key biophysical characteristics of viticulture are often unaccounted for, including the variability of grapevine phenology and the exploitation of microclimatic niches that permit successful cultivation under sub-optimal macroclimatic conditions. We consider how these same biophysical characteristics permit a variety of strategies by which viticulture can adapt to changing climatic conditions. The ability to realise these strategies, however, is affected by uneven exposure to risks across the winemaking sector, and the evolving capacity for decision-making within and across organizational boundaries. The role grape provenance plays in shaping perceptions of wine value and quality, illustrates how conflicts of interest influence decisions about adaptive strategies within the industry. We conclude by considering what lessons can be taken from viticulture for studies of climate change impacts and the capacity for adaptation in other agricultural and natural systems.

The Heliothermal Index (HI) is one of the most common methods used to identify suitable areas for viticulture, using sums of air temperatures and latitude of locations. For this study, the HI and a modified version of it was applied to estimate annual wine characteristics in the federal state of Baden-Württemberg in southwest Germany. For this process, measurement data of 11 climate stations from 1960 to 2010 were used. In order to develop a method, 40 years of observation were selected and split into 30 years for developing an estimation method and 10 years for validation. The HI was modified by varying the time periods with which the index was calculated. Time periods with little effect on wine characteristics were identified and excluded to improve the estimation. The must density could be estimated with a bias of about 1 °Oe absolute value, which equals 0.21 °Brix, a mean average error (MAE) of about 4 °Oe / 0.82 °Brix and a root mean square error (RMSE) of about 5 °Oe / 1.03 ° Brix. The titratable acidity could be estimated with a bias of about 0.1 g/L absolute value, a MAE of about 0.7 g/L and a RMSE of about 0.9 g/L.
