The purpose of research is to establish the physicochemical and organoleptic properties of wines produced by OOO Imenie Sikory, determined by the agroclimatic and technological conditions typical for a given geographical object, in order to search for criteria for their geographical identification. The objects of research were wines produced by OOO Imenie Sikory in 2012–2016. The organoleptic properties of the wines (aroma, taste, color) were assessed, which are caused by the presence of a complex of volatile components: aldehyde, esters, higher alcohols, volatile acids; as well as the presence of organic acids, monomeric and polymeric phenolic compounds. The study established stable quality of the products with bright and complex varietal aroma characteristics typical for the following grapes: Chardonnay — floral and fruity with hints of apples; Sauvignon Blanc — floral with hints of gooseberry and currant leaf; Riesling – from floral-citrus to bright petrol-mineral; Pinot Noir – fruity-berry and musky notes; Cabernet Sauvignon – berry-fruity with shades of violet and morocco leather. The taste of white and red wines was distinguished by harmonious acidity and coherence, which is due to the implementation of the malolactic fermentation cycle, as a necessary technological method, which significantly affects the composition of organoleptic properties. As a result of the complex physicochemical and organoleptic analysis, the stability of the quality characteristics of the wines of OOO Imenie Sikory was established within each product name. The ranges of variation in the concentrations of a complex of volatile components, organic acids and phenolic compounds were identified, and their change depending on the aging period of the wine was shown. The properties of the studied wine samples were determined by the natural conditions characteristic of the geographical object Semigorye, the agrotechnical measures and technological methods used.
