However, during the process of defining these regions and sub-regions, the influence of climatic and soil factors crucial in the determination of dependent characteristics, such as the physiology of the grapevine and the quality of the grapes and wine, was not researchedVitis viniferathoroughly enough. This work presents the climatic characteristics of the existing sub-regions, as well as the results of the climate’s impact on the physiological reactions of the most common domestic grape cv. Vranac ( L.), facilitating a new viticultural zoning in Montenegro. Over a period of 56 years, the following climatic parameters were analysed: air temperature, precipitation, insolation and air humidity. These parameters suggest that all the sub-regions in Montenegro have uniform climatic parameters. The modification of certain climatic parameters is influenced by two large bodies of water – the Adriatic Sea and Lake Skadar – and by altitude. The duration of the individual phases and vegetation of the Vranac grape variety differed only slightly in the different sub-regions. As a reflection of the influence of climatic factors in different locations, Vranac grape and wine was analysed chemically and given a sensory evaluation. The analysed parameters indicate a nearly uniform chemical composition and sensoryKeywords evaluation of all wines. Wines produced at lower altitudes were distinctive for their superior quality. : Montenegro, viticulture, zoning, grape, wine, climate indeces Introduction According to the 2007 Law on Wine, Essentially, zoning involves the establishment Montenegro’s viticultural area is classified into ampelotechnicalof boundaries of methods lower-category are implemented. areas within two regions: the Montenegrin Coast and the Lake the entire viticultural region where similar Skadar basin (Fig. 1). It is more than obvious that the previous Although Montenegro is an old European names of the regions have been only slightly and Mediterranean grape-growing country, due changed. to regaining statehood only in 2006 and its small Zoning practices were originally introduced viticultural region covering only 2,700 hectares by growers of Old World established wine regions (National Bureau of Statistics, 2014), it is facing a solely to protect their livelihoods (Skelton, 2009). zoning problem as a new viticultural country. A large number of established grape-growing After World War II, Montenegro, as a Yugoslav countrieset al such as France, Italy and Spainet completed al republic, was classified as an Adriatic grape- the zoning of their viticultural territory long ago growing region, with two sub-regions – the (Party ., 1990; Lebon,et 1993; al Sotés ., 1994; Montenegrin coast and the area of Lake Skadar Falcetti, 1994; Carbonneau, 2000; Tonietto and (Jelaska, 1954; Ulićević, 1959). In the 1970s, the Carbonneau, 2004; João ., 2012). new zoning classified the grape-growing regions With regard to zoning, New World regions, into two viticultural zones: the Montenegrin coast such as California, Chile, South Africa, Australia and the Titograd area (Grupa autora, 1977). and New Zealand use a classification based on 74 SAVIĆ and VUKOTIĆ Figure 1. Montenegro and the borders of grape-growing regions temperature accumulation (degree days), that the demarcation of registered designations of was proposed by Amerine and Winkler (1944). origin or protected geographical indications is one Today, climate indices have also been introduced of the most obvious zoning aims. (heliothermal, hydrothermal, bioclimatic, etc.), as In New Zealand, Shanmuganathan (2010) well as the impact of the soil and the interaction used cartography and two main categories that between the soil and the grapevines that affects included dependent factors (grape yield and wine the quality of the grapes and wine produced quality, but also others), as well as independent (White, 2003). An approach to particular zoning factors (climate, environment, etc.). The factors involves analysis using a Geographical Information producersof both categories to understand were analyzed and predict using the historical, reaction System (GIS) which incorporates factors related to biotic and modelling data, thereby enabling climate, topography and the soil (Madruga, 2015). In the process of zoning, phenology is also of grapevines to different impacts. taken into account (the duration of the ripening Gridded daily precipitation totals and daily of grapes, temperature accumulation and minimum, mean and maximum air temperatures precipitation during the growing season) (Köse, across Europe were used for the bioclimatic 2014), then the soil’s gravel content, aset well al as the index calculations (Santos et al., 2012), and percentage of clay and sand in the soil next to the the application of the EFI index (ecologicalet root system (Carbonneau, 2003, Tesic ., 2010) alfavourability index) for the evaluation of the and other factors. favorability for ecological viticulture (Antoce Various authors have suggested different aims ., 2007). of zoning: Winkler et al. (1974) stated that the taste Digital mapping methods and remote sensing of wine in very warm regions is often pungent and techniques have revolutionized viticultural zoning raw, while other ingredients are poorly balanced, at all levels, ranging from individual plots to the therefore, these regions can usually produce regional level. only dry table wines. Dokoozlian (1996) said However, none of these classifications can that viticulture zoning among wine producers or be accepted or applied unconditionally. A large professional organizations pertains to the spatial number of environmental factors act in unison, characterization of zones that are likely to produce reducing or increasing the intensity of each of grapes or wines of similar composition, while them. Also, one should not forget that the climate enabling operational decisions to be implemented is a dynamic category. We see, depending on the at the various stages of production.

The areas at higher altitudes are used wine-growing areas, study the climatic impacts for the development of the tourist infrastructure, on the physiology and quality of Vranac grapes and wine, the most widespread grape variety in Besides the state-owned company Plantaže, Montenegro, as well as to find justification for the in recent years private wine cellars have also existingMaterials zoning. and methods been increasingly planting varieties (Chardonnay, Viticultural zone of Montenegro Malvasia, Sauvignon Blanc and Krstac) for the production of white wines.
