Abstract

In order to increase the production of original and recognizable sparkling wines, base wines from autochthonous grape varieties can be used for their preparation. Based on the studied basic and advanced physicochemical and organoleptic characteristics, it was concluded about the possibility of using autochthonous grape varieties - ‘Makhrovatchic’, ‘Tsimlyanskii Belyi’, ‘Tsimladar’, ‘Kefesiya’, ‘Kokur Krasnyi’ and ‘Chernyi Krymskii’ - for production of high-quality sparkling wines. The relationships of the phenolic complex components with the parameters of sparkling wines, characterizing their appearance, was established, so for white sparkling wines - mass concentration of polymeric forms of phenolic substances with yellowness index (r = 0.925); for red ones - mass concentration of monomeric forms of phenolic compounds and mass concentration of coloring agents with the index of color intensity r = 0.580 and r = 0.786, respectively; for white and red sparkling wines - mass concentration of polymeric forms of phenolic substances with a maximum foam volume (r = 0.628). It was also noted as a positive factor that all samples accumulated a sufficient amount of the bound CO₂ (not less than 8% of the total bottle content.
