The aim of the presented article is to evaluate the impact of climate change on the sugar content of grapes in the Czech Republic during the period 2000–2019 through selected indicators on the basis of available secondary sources. Attention is focused on the developments in both the main wine-growing regions of Moravia and Bohemia. In the field of viticulture and wine-growing, the sugar content of grapes, as a basic parameter for the classification of wines, plays an important role. In the Czech Republic, the average sugar content of grapes has had a constantly growing trend. This trend is evident both in the wine-growing region of Bohemia and in the wine-growing region of Moravia. The impact of climate change, especially the gradual increase of average temperatures in the growing season, cannot be overlooked. It greatly affects, among other things, the sugar content of grapes. Calculations according to the Huglin Index and the Winkler Index were used to determine the relationship between climate and sugar content. These indexes summarize the course of temperatures during the entire vegetation period into a single numerical value. The results show that both indexes describe the effect of air temperature on sugar content in both wine regions of the Czech Republic in a statistically significant way. The Huglin Index shows a higher correlation rate. The Winkler Index proved to be less suitable for both areas. Alternatively, the Winkler Index calculated for a shorter growing season was tested, which showed a higher degree of correlation with sugar content, approaching the significance of the Huglin Index.

The current globalized world requires individuals to take responsibility for their decisions. Therefore, it is necessary that the younger generation reach a certain level of knowledge, including knowledge of financial literacy. Financial literacy covers an important area security in old age. The aim of this paper is to assess the level of financial literacy amongst university students, with a focus on income security in old age. Primary data were obtained by quantitative research using a questionnaire survey (n = 1 437) in 2018 amongst full-time bachelors and masters degree students at three universities. The selected universities focus on economy and agriculture and each of them is located in a different region of the Czech Republic. The results show that 47.8% of respondents worry about their income security in old age. As a way of financing the retirement, most of the respondents chose the option “from the state pension and in another way”. Statistical evaluation proved dependence between the gender of respondents and the responses mentioned above. Women more often chose the “from state pension and in another way” option than men. On the other hand, men chose the “in another way” option more often. It follows that men do not want to be dependent on the state, but they want to secure themselves in another way.
