Вот ПОЧЕМУ виноград кислый — ранняя чеканка губит сахар, не сорт #виноград #дача

Do you have large, beautiful grapes every August, but the berries are sour and don't ripen before the Feast of the Protection of the Virgin? You're probably pruning according to the calendar, as your neighbors taught you, for Ilya's Day or the Feast of the Savior. But by this time, the vine is still actively growing, and your early pruning only reduces its sugar content. I'm Alexey Berezhnoy, I've been gardening for sixty years, and I've been growing grapes since the 1980s. I'll tell you about the most reliable sign of grape pruning, which the vine itself gives, and which you simply need to watch for. This is the straightening of the shoot crown, plus the beginning of the berry's softening. I'll show you how many leaves should be left above the bunch (at least twelve, ideally fourteen to eighteen), why early pruning reduces sugar content, how to distinguish pruning from pinching, and what the difference is between the Isabella, Moldova, Arcadia, Lydia, and Vostorg varieties. I'll tell you about a story from 2003 with my godfather Mityai, when I pinched grapes according to the calendar and got half a bush of vinegar wine. This video is for anyone who has grapes at their dacha or on a plot in the foothills, south, or central Russia. Please tell us in the comments what variety you have and how old the vines are.
