Plain Language Summary Global warming and the wine industry Global warming is a phenomenon that refers to the gradual increase in Earth’s average surface temperature caused by human activities. This phenomenon has far-reaching consequences that affect the environment, society, and economy and has created a multitude of challenges for the wine industry. The wine industry faces many problems due to global warming, affecting grape cultivation, wine production, aging, and quality management. To analyze the negative impact of global warming on the wine industry and to examine ways to maximize welfare and profit in the face of climate change, we used a mathematical model that considers the various stages of wine production. Our analysis shows that global warming affects the wine industry’s equilibrium, causing measurable distortions and an inefficient market solution. However, our analysis also indicates that adaptation to global warming is possible by adopting and adjusting new agricultural practices. This means winemakers can adjust their agricultural practices to adapt to the changing climate and still produce high-quality wine. Our findings suggest that global warming has a notable negative impact on the wine industry. To address this issue, policymakers should promote the adoption of renewable energy sources and sustainable farming practices in the wine industry. They should also provide financial incentives and regulatory support to maximize welfare.

Research background:
The global agri-food complex changed in last years. From global scale point of view agri-food complex must face new challenges in the field of changes of natural conditions and ...in the field of social and trade relations. Vine growing is due to the specific demands on its production is a suitable representative of these global changes.
Purpose of the article:
The aim of this paper is to investigate relationship between area of vineyards and its production in context of globalization.
Methods:
Secondary data were obtained from official information sources. From the point of view of the methodological apparatus, the analysis of time series were used. Based on the selection of a suitable trend function were forecasted following two period. Furthermore, modifications to the data matrix were made. For individual variables, which were compared using appropriate statistical methods. The growth coefficient was determined. The relationship between the variables was investigated.
Findings & Value added:
Based on the data, there is an obvious degressive trend in vineyards, which could be caused by the European Union standard for maximum planting up to 2 % per year. Wine production fluctuates significantly during monitoring and it is very difficult to determine its trend. In the last decade, there is possible to see an increasing of wine consumption. In future research, the relationship between consumption and production, or the production and overall performance of agriculture as a sector, may be examined.
Growing of high-qualitative table grapes for storage and transportation is carried out by using separate agrotechnical methods. To study these problems we have founded experience in the farm “Haji ...Aleddin farmer Ltd.” 100 ha of vineyards possess in this farm.
It was established that the qualitative crop suitable for storage and transportation the of table varieties Tayfy pink obtained by remaining 40 bushes of green shoots after the first debris and pruning of fruit shoots to the length of 12–15 holes. And Sultana varieties respectively 35 green shoots and trim the length of 10–12 buds.
This paper reviews the authors’ theoretical and empirical views on the factors influencing wine production. The theoretical framework indicates the presence of many factors affecting the vine growing ...and winemaking enterprises. The indicators are summarised in terms of terroir, the competitiveness of the enterprise, its ability to innovate, the production quality and the quality of wine product intended for the market. The analysis assists in highlighting the following more important conclusions: evolution of the object of study from an enterprise to a whole supply chain; regarding the subject of study, many factors that affect the object, combined into leading factors and indicators characterising the factors, can be identified; the terroir and the human factor are the main factors influencing the quality of the wine produced.
To cope with different types of risks, farmers can implement on-farm strategies and risk-sharing strategies. Risk management tools within EU Common Agricultural Policy are subsidized crop insurance, ...mutual funds (MF), and income stabilization tool (IST). While subsidized crop insurance is widely applied, IST and MF are not so common. Price volatility and climate change risk significantly influence farm income. Mediterranean area is especially exposed to climate change, so Istria County as part of Mediterranean is chosen for research. IST could protect against income variability, but more research and discussions are needed prior to its commercial scale implementation. Qualitative research on the small sample was applied with the goal to explore attributes that could impact the selection of IST. Paper provides an overview of IST and previous experience of IST on the EU level, on the basis of semi structured interviews, explains the perception of climate risks and IST on wine cases in Istria. The results show that all selected cases were familiar with subsidized crop insurance; however, they were not familiar with IST. After being introduced to the IST, wine producers were ready to consider its application. Lack of experiences in business linkages could be a constraint in the development of IST and challenge for policymakers.
•Grape seeds as a by-product after winemaking may be a valuable source of nutrients.•Tocol and polyphenol contents are affected mainly by winemaking and grape variety.•Essential macro- and ...microelements are beneficial phytonutrients of grape seeds.•Microelement content in grape seeds is particularly affected by a vine-growing area.•White or red vinification has significant impact on remaining nutrients in seeds.
Seeds of twelve white and red vine varieties cultivated on six vine-growing areas were assessed as a by-product after winemaking on the contents of total polyphenols (TP) and phosphorus (P) spectrophotometrically, total tocols (TC) by HPLC-FLD, and metals (Ca, Mg, Na, K, Fe, Zn, Cu and Mn) by FAAS. Remaining TP and TC levels were mainly affected by the variety, while levels of microelements (Cu, Mn and Zn) and P or K by the vine-growing area. The highest TC levels were found in the seeds of the Müller Thurgau, Pinot Noir and Zweigeltrebe varieties. Different white and red winemaking methods have significant impact on the TP content with higher remaining levels in white varieties. Conversely, red varieties contained higher levels of macroelements except P, however no significant differences between varieties have been found. Red varieties contained higher Fe, Cu, Zn and comparable Mn levels. Results herein revealed the considerable potential of grape seeds, a by-product of the vinification process, as a valuable inexpensive source of high added value of nutritionally beneficial compounds – polyphenol and tocol antioxidants and macro- and microelements for use as feed additives in animal nutrition.
The main aim of this work was to analyse the diversity of wild Saccharomyces cerevisiae isolated from spontaneous fermentations of grapes collected from heroic vine-growing area.
A first screening ...based on several technological traits was used to select 39 strains among 132 isolates. By using three molecular typing techniques (evaluation of cell wall gene polymorphisms, mtDNA restriction analysis, inter-delta amplification analysis) a significant genetic variability was found. The analysis of principal aromatic compounds produced during inoculated fermentation of two grape musts demonstrated the strain impact on wine flavour and a significant influence of grape must on strain metabolic behavior. One selected strain was used in fermentation at cellar level and the analysis of inter-delta region on yeast colonies isolated during the process revealed the high-implantation ability of this strain. The obtained results demonstrate the usefulness of different molecular and technological markers for the evaluation of natural biodiversity among S. cerevisiae strains. This study represents an essential step towards the exploitation and the preservation of biodiversity of strains isolated from heroic vine-growing area. Selected S. cerevisiae strains could represent starter cultures available for winemakers addressed to production of quality premium wines maintaining differential properties of their own area.
► We analyzed wild Saccharomyces cerevisiae yeasts from grapes of “heroic vineyards”. ► Use of different molecular techniques is necessary for reliable strain biotyping. ► Strain variability for metabolite production was tested in two grape musts. ► High metabolic biodiversity was found only in the isolation grape must fermentation. ► A heroic vineyards strain showed higher implantation than strain of different origin.
Unequivocal evidence of Roman vine cultivation and wine making is provided from studies of combined archaeological remains from the site of Gasquinoy (Southern France). Waterlogged and charred plant ...material (fruits/seeds/wood) collected from wells located in the close vicinity of cultivated fields and wine making establishments confirms the local significance of this activity. The results offer insights on particular aspects of wine production (‘traumatic’ treading of grapes and straining) and provide evidence of secondary agricultural activities such as cereal production and fruit tree cultivation. The potential use of monocotyledonous stems such as
Arundo/
Phragmites in the farming system is discussed.
Purpose
Vine growing for the production of wine constitutes one of the major areas of agriculture of the Czech Republic, and in recent years, it has been qualitatively improved. The purpose of this ...paper is to find out whether oligopolistic market structures have come into being on the sparkling wine market in the Czech Republic, and whether some wine firms have a dominant position on the sparkling wine market.
Design/methodology/approach
The purpose of this study is to find, compare and carry out a statistical analysis of data on the production and sale of sparkling wines in the Czech Republic, in particular the indicators of the sales and profits of the dominant producer, Bohemia Sekt. In retail chains in the Czech Republic, the price of domestic and foreign sparkling wines was then compared with a comparative analysis.
Findings
The dominant seller of sparkling wine on the Czech market is Bohemia Sekt, which is also the largest domestic non-sparkling and sparkling wine producer. Bohemia Sekt sold 11 m bottles of sparkling wine on the Czech market in 2015 and maintained a 67 per cent share of the domestic market. Traditionally, Christmas time and the end of the year is the main season for selling sparkling wines in the Czech Republic, as more than one-third of the annual production of all wineries is sold at this time.
Originality/value
The paper presents a finding about the consistency of the prices of sparkling wines offered in retail chains in the Czech Republic. This confirms the validity of using the model of oligopolistic competition with a dominant company on the sparkling wine market in the Czech Republic. The dominance of Bohemia Sekt in the given market is mainly due to the loyalty of Czech consumers to this brand.
Vine in the Slovene Kras (Karst) region is unique due to the specific geologic, climatic, geomorphologic and soil conditions. Small sized villages with low number of inhabitants are typical for the ...area as well as fragmented land units. The percentage of the active population in agricultural sector is continuously decreasing. With the land use data for years 1961, 1994 and 2000 we studied the changes in land use by land register units in the area.Abandonment of arable land and its grass overgrowing, insufficient vineyard renewal, abandonment of cattle breeding and forest overgrowing are the biggest threats to the vine growth in the area. Due to forest overgrowing the local wind called "burja" is weaker and less frequent which leads to higher relative air moisture. The last mentioned fact is of the most important ones, because the local vine is very sensitive to high air moisture conditions which cause different kinds of plant diseases. The renewal of the vineyards in the Karst area is insufficient to maintain the present situation. In the last few years local farmers have been trying to protect the local wine called "Teran" as a regional specialty.
