May : In our vineyards . . .

May is a turning point in the vineyard vegetation cycle. The vineyard growth accelerates. It is necessary to ensure protection against the most dangerous parasites: mildew and oidium. The suckers growing at the base of the vine stock must be removed. This long and fastidious work is essential to restrict the risks of contamination by the mildew and oidium spores in the soil. In addition, it protects the vines against any risk of exhaustion and thus a reduction of the grape sugar content. The grape clusters appear. At first, they will extend and bear flowers, which will convert into berries after fecundation. The flowering period is essential, as it determines the yield of the future crop. Favourable weather conditions (sun, heat) are also essential to ensure a good fecundation of the flowers. A bad fecundation would result in a smaller crop as a result of flower abortion and a smaller size of the berries (millerandage).
