Grape Forty Years of October

The grape variety "Forty Years of October" is a technical variety developed by the Institute of Viticulture and Enology named after V.E. Tairov. This variety was obtained by hybridizing the varieties Kopchak and Alicant Bouschet and occupies significant areas in the Odesa region. The vines are vigorous, with medium-sized, round leaves featuring sharp teeth. The flowers are hermaphroditic, which contributes to good fruiting. The clusters are medium-sized, conical or branched, with medium-sized, round, black berries and dense flesh. The berries have a dark ruby or dark blue color with juicy juice and a pleasant flavor with cherry undertones. The growing season of the variety lasts approximately 155 days, with berry ripening occurring in the third decade of September, classifying it as a late-ripening variety. The average cluster weight varies from 180 to 210 grams. The juice sugar content reaches 18-22%, and acidity ranges from 8-11 g/l, making this variety suitable for producing high-quality red table and fortified wines with good color and extractive properties. The yield is high and can reach 80-120 centners per hectare, indicating its economic attractiveness for grape growers. The variety exhibits resistance to diseases such as mildew and gray mold, but is sensitive to frost and has low winter hardiness, requiring careful selection of planting location and agronomic practices. Pruning is recommended on 4-10 buds depending on the growth strength of the shoots and the intended use of the harvest. It adapts well to rootstocks such as Riparia x Ruprectis 101-14 and Berlandieri x Riparia Teleki 5Ц, promoting its adaptation and stable fruiting.
