The most significant risk for viticulture is that the sugar content of the grapes will increase in the future due to rising temperatures. As a result, it will be possible to produce wines with increasing alcohol content in the future. Excessively high alcohol content can significantly reduce the wines’ marketability and viticulture’s profitability. Our study seeks to answer how the expected drought in the Southern and Central regions of Europe will affect the future change in the sugar content of grapes. The degree of dryness was examined using the dryness index in the study. Finally, it was analyzed how the dryness index affects the past and future occurrence of maximum sugar content for six grape varieties. The probability of the occurrence of maximum sugar content for most vine grape varieties will decrease in the near future. However, in the distant future, there is a likelihood that the occurrence of maximum sugar content will increase again. If we can maintain the DI ≥ −10 condition with regulated deficit irrigation, the probability of the occurrence of maximum sugar content may decrease significantly in the near future. Ensuring moderate dryness is the only way to achieve the proper sugar content.

To produce high-quality wine in vineyards, it's necessary to understand the characteristics of the cultivation environment. This knowledge is obtained through long-term monitoring. To provide this knowledge, we developed a new wireless sensor network (WSN) that could be used to monitor the vineyard growing environment. To support the use of this data, we developed a Web-based application to help growers take advantage of the information obtained on cultivation conditions. In the WSN, we adopted the 920 MHz band that is used in the Wi-SUN standard (to replace the older 2.4 GHz band) to obtain data from a weather station and soil moisture sensors. In the WSN data-acquisition method, data was standardized using a predetermined name for each sensor and standardized measurement units. The accuracy of the acquired weather station data was verified by comparison with data from a nearby Japan Meteorological Agency weather station. The Web application let growers improve cultivation management using data on the growing environment, such as the cumulative growing degree-days (GDD), growing season temperature (GST), cool-night index (CI), heliothermal index (HI), biologically effective degree-days (BEDD), and dryness index (DI).

In many regions, water availability influences grape yield fluctuations more than thermal conditions. This study analyzes dryness indices calculated from observed and simulated RCM data to establish statistical relationships with observed yield data, considered an indicator of food safety. Five dryness indices were analyzed: the number of days without rain, the maximum number of consecutive dry days, climatic water balance, dryness index, and vineyard water indicator. These indices were analyzed for three periods: 1986–2005 (recent past), 2016–2035 (near future) and 2081–2100 (distant future). After this analysis, quadratic regression connections were established between the indices and available wine grape yields in the 22 wine regions of Hungary for 2005–2021 without information on grape varieties and for 2017–2021 with data on grape varieties. Linear agro-technological trends were extracted from these wine grape yield series, whereas the residuals exhibited significant quadratic regression in slightly over 50% of the indices and regions, according to the F-test for the 17 year series. For the short series, these proportions are 29 and 27% for the selected seven white and seven red wine grapes. According to the most significant quadratic regressions, combined with the projected dryness indices, we can expect less average yields with higher interannual variability in the future.
