Flavoring wine with Artemisia species, together with other aromatic herbs and/or fruits, is a practice that has evolved in different parts of Bulgaria. The aromatized wine-based beverage, called pelin, is named after the Bulgarian common name for the genus Artemisia. In this paper, we present Zmeyovski pelin, the history of which dates back to the early 20th century. We employed semi-structured interviews with 15 pelin producers from the Zmeyovo village with an age span from 44 to 83 years. The relative frequency of citation for each stated taxon was recorded. We explored the changes in the plant knowledge of the pelin makers and discussed the drivers for it. From a modern perspective, pelin can be considered a functional beverage since the aromatic plants and fruits adds a variety of biologically active substances to it, thus enhancing its health benefits. We regard the consumers’ inquiry about the benefits of the added plants as a driver for mitigating the plant awareness disparity among the local community.

Introduction. The condition of the vegetation cover can be traced from Space. Aim of the research. To assess the condition of the vegetation cover in Bulgaria during the last twenty years – its distribution over the country, its change in connection with the typical climatic changes, its seasonal change. Material and methods. The vegetation index NDVI according to NASA data was used to analyze the condition of the vegetation cover in Bulgaria for the years 2000-2020. The methods used were: seasonal data decomposition, t-test, GIS methods for spatial representation of data, Fourier analysis. Conclusions. 1. During the summer months the vegetation in the eastern parts of the territory of Bulgaria is noticeably weaker than in the western parts. The influencing factors-drought and frequent fires are probably related to global warming. 2. For the territory of Bulgaria there is a seasonal rotation of the horizontal gradient of the vegetation index in a counterclockwise direction-from east to west in summer, from northeast to southwest in autumn and from north to south in winter. 3. There is a winter increase in vegetation for Northern Bulgaria and to the greatest extent for Northeastern Bulgaria, as well as for Southwestern Bulgaria. Together with the decreasing snow cover, the winter vegetation contributes to the drought in the eastern parts of the country.
