To the wineexpert (oenologist) and to the winemaker rain is appreciated when necessary. Indispensable during the period of ripening, that is to say when, at the beginning of maturation, fruits have the greatest need of it and an excessively dry climate could compromise it.
Rain is desirable immediately before the harvest as a slight water stress speeds up the loss of water from the grape.
The scientific literature considers the vine to be cultivable when the rainfall is at least 700 mm/year, of which at least 400 mm are needed during the vegetative period.
