coulure

Term (French: coulure) for a fertilisation disorder in the vine. Other terms are "rooting out", "trickling out" and, in extreme cases, "trickling through". This can occur up to three weeks after flowering and is manifested by the loss of flower buds or young, usually still very small berries the size of peas, which fall from the stems. For the most part, this process is normal, because a vine can never bring all the berries of all the grapes to ripen completely. If fertilisation does not take place or is inadequate, berries do not form at all, because such blossoms fall off. Depending on the grape variety, the flowering rate is only 30 to 60%. After flowering, the young grapes are most susceptible to this when they need vital carbohydrate resources to develop fully.
