Crimean autochthonous grape varieties as a factor of high-quality winemaking in a changing climate

An increase in ambient temperature affects the quality of wines, which is largely due to a change metabolism phenolic substances grapes. A possible solution problem use autochthonous varieties adapted unfavorable conditions. The influence agroecological conditions 4 vineyards on complex Crimean grape variety ‘Kokur Belyi’ has been studied. Methods geoinformation and mathematical modeling, HPLC were used. It established: differ heat resources row: Vilino < Privetnoe Solnechnaya Dolina Morskoe. supply territories caused accumulation acids, flavonols, (+)-D-catechine procyanidins B4 seeds decrease content (-)-epicatechine, B3 skin pulp. highest lowest monomeric components pulp was determined grapes from village Morskoye. Grapes contain 3.7 times less seeds, 6.5 3.6 more Conclusion: contributes both biosynthesis their polymerization during ripening grapes, leads significant differentiation Belyi’.
